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.
Answer:
Platysma.
Explanation:
Platysma is the sheet of muscle that arise from the chest and deltoid muscle. The muscle rises over the clavicle.
Platysma muscle comes upward from the slanting manner by the sides of the neck. This muscle draws the corners of the mouth and lower lip. Hence, platysma muscle is used to express horror and for the pouting.
Thus, the answer is platysma.

Answer:
The answer to fill in the blanks in the question: PCO2 is:____ in alveolar air and ____ in tissues, would be, D: 40mmHg for alveolar air and 45mmHg, for the blood that is returning from the tissues.
Explanation:
The reason for this comes from the purpose and the places that respiration takes place. Respiration has two purposes: take in oxygen from the air, and release CO2, a waste of cellular respiration processes, produced by the cells in tissues. The reason for the differences in molecules of CO2 being higher in the blood that comes from tissues, and not in the air from the alveoli is that in the alveoli, oxygen dissolves into the tissue of the alveoli and passes to the blood that is prepared to capture as many of the molecules as possible, to carry them to the cells. But in tissue blood, since oxygen has already been used in respiration, there is a high production of CO2. These molecules will dissolve in the blood and will be carried to the lungs, but this time to be released out of the body.
