Answer:

The answer to the question: Name the phase when the atrioventricular valves and the semilunar valves are all closed during ventricular diastole, would be: the isovolumic, or isovolumetric relaxation.

Explanation:

The systolic and diastolic cycles of the heart ensure that blood is always being circulated around the body from the heart, and from the body to the heart. While systole implies the moments of contraction and active motion of the heart muscles to ensure the correct passage of blood from the four chambers of the heart (atria and ventricles), to and from the body, diastole is the time when either the atria, or ventricles relax to allow the flow of blood into them. To also ensure this process is seamless, there are a series of valves, the atrioventricular valves, or AV valves, and the aortic and pulmonary (semilunar) valves, that will ensure that blood can flow from the atria to the ventricles (AV valves) without flowing back, and that blood will flow towards the body through the aorta, and the lungs, through the pulmonary arteries, through the aortic and semilunar valves, without going back into the ventricles. At one point, when the ventricular diastole begins, there is an early stage known as the isovolumic, or isovolumetric stage, meaning, volumes are pressures are equalized and then both the AV valves and aortic and pulmonary valves are closed only for a bit as the ventricles relax. Not soon later, the AV valves will start opening to allow the gentle flow of blood from the atria, to the ventricles, before actively initiating atrial systole.

Which of the following is true concerning oxygen in regards to aerobic respiration?
andrew-mc [135]

Answer:

Correct answer is c. It is the final electron acceptor in the aerobic respiration.

Explanation:

Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.

Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.

Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.

The nurse knows that which statement is a description of peritoneal dialysis when compared to hemodialysis:
Feliz [49]

Peritoneal dialysis and hemodialysis are both used to manage kidney failure. Hemodialysis involves the use of a synthetic membrane called a dialyzer, which filters wastes and removes excess fluid from the blood. Peritoneal dialysis does not use a dialyzer.

<h3>What do you mean by Dialysis?</h3>

Dialysis may be defined as the process of removing blood from an artery, purifying it by dialysis, adding vital substances, and returning it to a vein.

In hemodialysis, your entire blood is circulated outside and it is filtered with the help of an instrument known as a dialyzer. While in peritoneal dialysis, clean blood flows through a tube into the part of the abdomens. The biggest difference in these two dialysis processes is that Hemodialysis requires an artificial kidney machine to filter blood while peritoneal dialysis does not require such kind of arrangement.

Therefore, the difference between hemodialysis and peritoneal dialysis is hemodialysis occurs outside the body while peritoneal dialysis occurs inside the body.
