Introduction:
Kidneys are primarily involved in the process of excretion. The renal cells remove the waste products of the blood through filtration. The kidneys are also responsible for the maintenance of the homeostasis between the body constituents.
Answer to Problem 1DYKB
Correct answer:
The correct answer is option (d) production of plasma proteins.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) plasma proteins are produced by the liver (reticuloendothelial cells). Hence, this is not the function of the kidneys.
Explanation for incorrect answer:
Option (a) the process of gluconeogenesis is controlled by insulin and glucagon hormones. This process takes place in the liver and kidneys. Hence, this is an incorrect answer.
Option (b) the protein called erythropoietin is responsible for red blood cell production. This protein is generated in the renal cells in response to low R.B.C count. Hence, this is an incorrect answer.
Option (c) kidneys also regulate blood pressure by releasing a hormone called renin. This is released in response to low blood pressure. Hence, this is an incorrect answer.

- Mr. Duderino comes to the doctor with high blood pressure. Test show that he also has elevated levels of renin in his blood and atherosclerotic plaques that have nearly blood blow flow through his renal arteries. Mr. Gregory is puzzled. Explain to him how decreased blood flow in his renal arteries could cause renin secretion to increase. Map the pathways through which elevated renin causes high blood pressure for Mr.Gregoryarrow_forwardWhat would have to happen to the afferent and efferent arterioles to increase pressure? What would have to happen to decrease pressure? Think in terms of constriction and dilation. Afferent Efferent To increase pressure To decrease pressurearrow_forwardWhich of the following is NOT a function of the excretory system? * Filtration of wastes from the blood. Secretion of ADH from the collecting duct. Maintaining pH balance by secretion of H+ ions. Osmoregulation via sweating. Releasing carbon dioxide waste from the lungs.arrow_forward
- Under circumstances of having low blood pressure , how does the sympathetic nervous system decrease glomerular filtration rate ? stimulates constriction of the efferent arteriole only stimulates relaxation of the mesangial cells stimulates secretion of erythropoietin stimulates constriction of both the afferent and efferent arteriolesarrow_forwardWhich of the following are an effect of angiotensin II production? Select all that apply. Group of answer choices ADH release Rise in blood pressure Aldosterone release Vasodilationarrow_forwardWhich of the following is not a function of the kidneys?

- In the presence of anti-diuretic hormone (ADH), which of the following does NOT occur? OAquaporins will be present ONLY in the apical membrane of the collecting duct ADH will bind to an ADH receptor, which is a metabotropic receptor O Adenylate cyclase will be activated, producing CAMP OWater flows down its concentration gradient, from high to low solute concentrations OAll of the above would occurarrow_forwardWhen Jay had diarrhea his blood pressure dropped so his body took an action to compensate. Which one of the followings would better describe the mechanism Question 64 options: BP drop affects blood vessels baroreceptors and activates renin-angiotensin-aldosterone mechanism leading to increase ADH release BP drop affects blood vessels baroreceptors and activates renin-angiotensin-aldosterone mechanism leading to decrease ADH release BP drop affects blood vessels baroreceptors and inhibit renin-angiotensin-aldosterone mechanism leading to decrease ADH release BP drop affect blood vessels baroreceptors and inhibit renin-angiotensin-aldosterone mechanism leading to increase ADH releasearrow_forwardWhich statement concerning vasopressin secretion is NOT true? Group of answer choices Vasopressin secretion is closely ties to plasma osmolality changes in blood volume also alter vasopressin secretion a reduction in effective blood volume overrides the effects of plasma osmolality in regulating vasopressin secretion All of these are true no references, just homework.arrow_forward
