A patient lost a lot of blood during surgery and his blood pressure dropped from 120/80 to 90/50. Describe how the kidneys respond to this change in blood pressure
What will be an ideal response
When arterial blood pressure declines, special cells in the kidneys release the enzyme renin into the blood. Renin triggers a series of enzymatic reactions that produce angiotensin II, which is a potent vasoconstrictor. Angiotensin causes an increase in systemic blood pressure, and increases the rate of blood delivery to the kidneys and renal perfusion. It also stimulates the adrenal cortex to secrete aldosterone, a hormone that enhances renal reabsorption of sodium, and prods the posterior pituitary to release ADH, which promotes more water reabsorption. As sodium moves into the bloodstream, water follows; thus both blood volume and blood pressure rise.

Answer the following questions true (T) or false (F)
1. Serous fluid lubricates around organs and reduces friction as the organ moves against adjacent structures. 2. Negative feedback loops produce responses in the opposite direction of the initial stimulus while positive feedback loops produce responses in the same direction of the initial stimulus. 3. According to the principle of complementarity of structure and function, structure and function are related only at the cellular level.
