An increase in the permeability of the cells of the collecting tubule to water is due to a(n) ________.
OLga [1]
An increase in the permeability of the cells of the collecting tubule to water is due to an increase in production of ADH. Hormone ADH also called vasopressin is responsible for regulating the amount of water in the blood and is released from the pituitary gland based on signals from the hypothalamus, which detects the water levels of the blood. When too much water is in the blood, the hormone release is decreased and more water is excreted in the kidneys and thus increasing urine output.

g the period of time that begins with contraction of the atria and ends with ventricular relaxation is known as: question 36 opt
Archy [21]

The period of time that begins with the contraction of the atria and ends with ventricular relaxation is known as the Cardiac cycle.

<h3>What is a cardiac cycle?</h3>

The cardiac cycle describes a whole heartbeat from its onset to the beginning of the following pulse. It consists of the diastole, systole, and the interval in between. Heart rate, which is naturally expressed as beats per minute, serves as an example of how a cardiac cycle occurs.

<h3>Cardiac Cycle Physiology</h3>

The left and right halves of the human heart's four chambers make up the body. The right and left ventricles are located in the lower two chambers, while the left and right atria are located in the two top chambers. Pumping deoxygenated blood to the lungs through the pulmonary arteries and the pulmonary trunk is the right ventricle's main job. While the left ventricle is in charge of pushing freshly oxygenated blood to the body through the aorta.
