Question
Brenda donated Wood today decreasing the volume of blood in her circulatory system. As the blood was removed from Brenda's body, baroreceptors in her carotid arteries and detected a decrease in blood pressure. Which of the following mechanisms would directly restore her blood volume and thereby her blood pressure? systemic arteriole vasoconstriction atrial natriumetic peptide action on the granular cells of the kidney antidiuretic hormone acting on the kidney tubules staying in a reclined position The optimum pH of arterial blood is 7.4, while venous blood is 7.35. What is the reason for this discrepancy? Venous blood is blue. The presence of higher pCO_2 in venous blood. The presence of higher O_2 in arterial blood. Blood in arteries is under higher pressure. The chief cation of the intracellular compartment is Cl^- Mg^2+ k^+ Na^+Explanation / Answer
Ans 7 c antidiuretic hormone acting on the kidney tubules
As we know, more than half of the blood donated is made up of water, so immidiately after donation our body makes up for the loss by avoiding water loss from the body in the form of urine. This is regulated by anti diuretic hormone ADH
