A healthy elastic artery ________. Select one: a. reduces blood flow b. is compliant c. is a resistance artery d. has a thin wall and irregular lumen

Answer:

It allows for higher blood pressure in the systemic compared to the pulmonary circuit, leading to high efficiency of oxygenation of tissues. Oxygenated and deoxygenated blood have no possibility of mixing. Respiratory gas exchange is maximized because blood with lowest oxygen concentration from vena cava is directed toward the respiratory surfaces.

Explanation:

Final answer:

The separation and independent pumping of blood through the heart allows for efficient oxygenation of the blood and delivery of oxygenated blood to the body.

Explanation:

The consequence of the separation and independent pumping of pulmonary and systemically-derived blood through the heart is that it allows for efficient oxygenation of the blood and delivery of oxygenated blood to the body. The right side of the heart pumps oxygen-poor blood to the lungs where it receives oxygen, while the left side of the heart pumps oxygenated blood to the rest of the body. This separation ensures that oxygenated and deoxygenated blood do not mix, allowing for efficient oxygen exchange in the lungs and delivery of oxygen to the body's organs and tissues.

Drainage

Explanation:

Root operation refers to the procedures performed on the medical patient which includes taking some part of the body, putting in or putting back to the body.

In the given question, the synovial fluid present in the joints which reduces friction and absorbs the shock is taken out from the body for the diagnostic and therapeutics. The root operation performed to take out the fluid or the gases from the body is known as the "drainage root operation" like the taking out of the synovial fluid.

Thus, Drainage is the correct answer.

“Taking or letting out fluids and/or gases from a body part.”

irst, your doctor will give you a local anesthetic to numb your joint. Then, she'll put a needle in and take some fluid out. How much depends on the size of the joint and how many tests you're going to have.

Your doctor will send your fluid to a lab, where a technician will do one or more of these:

Check your fluid's color and thickness

Measure chemicals like glucose, protein, and uric acid

See how many red and white blood cells and crystals your fluid has

Test for bacteria, viruses, or other germs

The 'root operation' in this scenario is 'drainage'. The key purpose of 'diagnostic needle arthrocentesis' is to remove the pathological fluid for diagnostic purposes.

In medical terminology, the term 'root operation' refers to the objective of the surgical procedure. In this case, the patient underwent a 'diagnostic needle arthrocentesis' - a procedure that involves the use of a needle to remove fluid from a joint space for analysis. The main purpose or 'root operation' of this procedure is 'drainage', because the main goal is to remove the pathological fluid from the knee for diagnostic purposes.

1) in "holistic." We take the whole picture of the patient, the environment, the parttern of the disease, the relationship of pet with owner which will enable us to develop treatment using a wide range of therapies for healing the patient, while Allopathic medicine, or allopathy, is a science-based medicine, such as the use of medications or surgery to treat or suppress symptoms or the ill effects of disease.

2) The conditions or problems veterinary chiropractic treatment might be used include degenerative joint disease, acute neck pain, autonomic nervous system problems, weakness of musculoskeletal. It is useful because animal chiropractors examine and treat areas that most times go unnoticed by the traditional veterinary care. By working in conjunction with veterinarians, whole patient treatment is achieved on the animal by chiropractors which restores the pet's optimal health.

3) Essential oils need to be used carefully with animals because without understanding how to use them correctly on the animals, it could become toxic, since the compounds they contain are biologically active, series of dangerous side effects could be caused and also organ damage if not used properly

4)Some veterinarians believe that herbal or botanical medications may be better than allopathic medications in some cases because they use the whole plant instead of one extracted part of the plant which makes the chemical less toxic, harsh, and reduces the amount of side effects.

5) some of the conditions that hydrotherapy might be used for include: Rett syndrome, cerebral palsy etc. it will be a good choice to help treat these conditions because being immersed in warm or hot water raises the body temperature, increasing blood flow around the circulatory system and so alleviating pain. The improved circulation will in turn help to heal injured tissues and rehabilitate damaged muscles or joints.

Answer:

3432 Hz.

Explanation:

The resonant frequency of the canal can be calculated as follows:

f = v/ 4l

Here, f is frequency, v is velocity of sound and l is the pipe length.

l = 2.5 cm = 0.025m and v = 343.2m/s.

Put these values to find the resonant frequency

f = 343.2 / 4 * 0.025.

f = 3432 Hz.

Thus, the answer is 3432 Hz.

Myoglobin is a protein which contains iron and can bind oxygen similar to the hemoglobins. The myoglobin is found in the muscle cells as it stores the oxygen for muscle.

The myoglobin is made of 156 amino acids which forms the globular structure and form 3D conformation.

The 3D structure of myoglobin is formed of the conserved structure of proteins called motifs and the domains. These motifs and domains are composed of the helical forms and plated sheets.

Thus, all of these is the correct answer.

Myoglobin is a complete three-dimensional protein structure, and although it contains domains and possibly motifs, it is incorrect to classify it solely as a motif or a domain.

Myoglobin is neither a motif nor a domain; it is a complete three-dimensional structure. Protein terminology often classifies structures in terms of motifs, domains, and complete structures. A protein motif is a reusable component of the protein's structure that performs a specific function. On the other hand, a protein domain refers to a portion of the protein's structure that can exist independently of the rest of the protein chain.

Myoglobin, as a complete three-dimensional structure, contains one or more domains within its structure and it might include motifs as functional components, but it is not right to classify it as solely a motif or domain.

Answer:

The rational explanations of doctors related to folk explanations concerning the properties of some foods began in the early days of ancient civilizations, when medicine was not yet a definable subject and folk explanations were the only ones who brought knowledge to bear on the field of health, and "try, taste and wait for the end of the process", was the only way to find out the food´s properties.

Explanation:

The ancient Greeks civilization, seeking for logic got curious about folk´s  explanations about existence and the whies paving the road for important developments the rational explanations in medicine and the relationship with food propierties.

The set up medical schools leaving the informatily of folk explanations hidden in the darkness, to open a path to the scientific observations of patients who were sick, although many of them were philosophers, they investigated on nutrition as possoble causes for illness, even though many folk traditions already practiced on certain foods to get healthier or to get health maintenance.

Doctor´s observations on folks´ remedies like using olive oil to increase temperature in the body, were the base for them to develop techniques, which could become sophisticated medicine procedures.

This theory remained popular in Western Europe until the 17th century. However, while the ancient Greeks pushed medicine forward in many ways, the theory of humors posed an obstacle to advances in medical practice.  But many of the folk´s natural remedies are similar to some home remedies practiced today.

Folks´ natural cures have doctors become herbalists treatment specialist, turning natural remedies into rational treatments using foods as the barley soup plus vinegar and honey to cough up phlegms; purging a person with food laxatives, diuretics or emetics to restore body´s balance; taking celery, to relieve inflamation; and in general rationalizing the concept of eating healthy foods, so the basis of modern medicine comes from the folk´s knowledge on food properties.

Meningococcal disease is caused by a bacterium called Neisseria meningitides. There are different serogroups of meningococci. Serogroups A, B, C, W and Y are the most frequent cause of disease worldwide, while serogroups B, C and Y are the most frequent cause of disease in the United States.

Explanation:

Meningococcal germ is spread by direct contact with the nasal or pharyngeal secretions of an infected person, that is, coughing, kissing or sneezing very close to other people, or also when people live together. Only people who have been in close contact (family unit members, intimate contacts, health care staff, etc.) should be considered for preventive treatment. These people are advised to obtain a prescription for an antibiotic, such as rifampin, ciprofloxacin or ceftriaxone. The casual contact that can occur in a regular class, in the office or in a factory environment and is usually not important enough to be of concern, so it will depend on whether the lady considers that she was in contact with some of the previously anticipated risk factors.

Answer:

Explanation:

A cardiogenic circulatory shock is the one in which any damage to the heart muscle or inability of heart to pump blood may cause a shock due to decrease blood supply to the brain.  this cardiogenic shock may also occur as a result of congestive heart failure evident in blood vessel defects. The hypovolemic shock occurs when the blood volume is decreased.

Vascular shock is a type of circulatory shock resulting from excessive vasodilation due to a loss of vasomotor tone.

Out of the listed options, the correct one is C. vascular shock. This type of shock is characterized by extreme vasodilation, which results from a loss of vasomotor tone. Vascular shock, also known as vasodilatory shock, can result from various conditions including severe inflammation and anaphylactic reactions.

Cardiogenic shock does not result from defects in blood vessels, but rather from the heart's failure to pump blood efficiently. Hypovolemic shock is actually caused by a decreased blood volume not increased. Lastly, the term circulatory shock is a general term used to describe inadequate blood supply to the body tissues, and not a specific type of shock itself.

Answer:

28.836 C

Explanation:

Data provided in the question:

Total number of electrons passed through the pocket calculator during a full day's operation = 1.80 × 10²⁰

Now,

We know that the charge of an electron is 1.602 × 10⁻¹⁹ C

Therefore,

The total charge moved through the calculator during the operations

= Total number of electrons passed × Charge of an electron

= (1.80 × 10²⁰) × ( 1.602 × 10⁻¹⁹ )

= 28.836 C

Total, 2.88×101 coulombs of charge moved through the calculator during a full day's operation.

The number of coulombs of charge moved through a pocket calculator when 1.80×10²⁰ electrons flow can be calculated using the charge of a single electron.

The charge of one electron is approximately -1.602×10⁻¹⁹ coulombs. Therefore, to find the total charge Q in coulombs, we multiply the number of electrons by the charge per electron:

Q = (number of electrons) × (charge per electron)

Q = (1.80×10²⁰ electrons) × (1.602×10⁻¹⁹ C/electron)
Q = 2.88×101 coulombs
Therefore, 2.88×101 coulombs of charge moved through it.

Answer: Δβ = 28.5278 dB

Explanation:

from the question we are given that;

the sound gathering area Ga = 15.0 cm²

total area Ae = 0.800 cm²

efficiency ε = 38 %

therefore we have that the effective gathering area of the stethoscope is;

As = ε Ga

As = 38 % × 15 = 5.7 cm²

But I ∝ 1/A

where Ie/Is = As/Ae

Ie/Is = 5.7/0.800 = 7.125

given that we are to assume that  sound is transmitted into a stethoscope 100 times, this gives

I'e/I's = Ie/Is × 100 = 7.125 × 100 = 712.5

Δβ = βe - βs = (10dB) log (I'e/Io) - (10dB) log (I's/Io)

Δβ = (10dB) log (I'e/I's)

Δβ = (10dB) log (712.5) = 28.5278

Δβ = 28.5278 dB

Final answer:

The solution calculates the gain in decibels produced by a stethoscope based on its sound gathering area, the eardrums' area, and efficiency. Therefore, the gain in decibels produced by the stethoscope is approximately 5.88 dB.

Explanation:

Solution:

Given information:

Sound is transmitted 100 times more effectively into a stethoscope compared to through the air.

Sound gathering area of the stethoscope is 15.0 cm².

Total area of the two eardrums is 0.900 cm² with an efficiency of 40.0%.

Calculations:

First, calculate the effective area concentrating the sound onto the eardrums.

Effective area = Total area of eardrums * Efficiency

Effective area = 0.900 cm² * 40.0% = 0.360 cm²

Now, find the gain in decibels using the formula:

Gain in dB = 10 * log₁₀(Effective area / Sound gathering area)

Substitute the values to calculate the gain in decibels produced by the stethoscope.

Gain in dB = 10 * log₁₀(0.360 / 15.0) ≈ 5.88 dB

Therefore, the gain in decibels produced by the stethoscope is approximately 5.88 dB.

Hope this helps.

The most reliable indication of adequate uteroplacental and fetal perfusion from an electronic fetal monitor (EFM) is the reactive pattern of fetal heart rate. This pattern showcases at least two accelerations of FHR over a 20-minute span, with each acceleration exceeding the baseline by at least 15 beats per minute and continuing for at least 15 seconds. Other features also suggest sufficient perfusion, but the reactive pattern is the most precise.

The data provided by an electronic fetal monitor (EFM) that most reliably indicates adequate uteroplacental and fetal perfusion is the reactive pattern of the fetal heart rate (FHR). The reactive pattern shows at least two accelerations of FHR during a 20-minute period, with each acceleration rising at least 15 beats per minute above the baseline and lasting for at least 15 seconds. This pattern usually indicates a well-oxygenated and non-acidotic fetus, thus indicating adequate uteroplacental and fetal perfusion.

It's also noteworthy to mention that features like fetal movements, variability in fetal heart rate, and the absence of decelerations also indirectly indicate adequate perfusion. However, the reactive pattern remains the most reliable data provided by an EFM for this purpose.
