_____ 1. All of following are functions of the kidney except
- a. gluconeogenesis, the formation of glucose from non-carbohydrate sources.
- b. release of erythropoietin to control erythrocyte production.
- c. control of blood pressure through the release of renin.
- d. production of plasma proteins to control blood volume.
Introduction:
Kidney balances the water and salt concentration in the body by removal of waste products from the blood. It maintains normal blood pressure by balancing the electrolytes such as sodium and potassium. It produces red blood cells and during starvation, performs gluconeogenesis.
Answer to Problem 1DYB
Correct answer:
Production of plasma protein to control blood volume is a function of the liver. Therefore, option d. is correct.
Explanation of Solution
Reason for the correct statement:
Option d. is given as “production of plasma proteins to control blood volume”. Protein present in blood such as albumin, fibrinogen, and globulin are produced in reticuloendothelial cells of the liver. Hence, the liver produces plasma protein which controls the blood volume.
Hence, option d. is correct.
Reasons for incorrect statements:
Option a. is given as “gluconeogenesis, the formation of glucose from non-carbohydrates source”. Gluconeogenesis occurs in the liver and kidney cortex. Hence, option a. is incorrect.
Option b. is given as “release of erythropoietin to control erythrocytes production”. Erythropoietin hormone is released by endothelial cells of peritubular capillaries present in renal cortex of the kidney. Hence, option b. is incorrect.
Option c. is given as “control of blood pressure through the release of renin”. Angiotensin-II hormone is responsible for increasing blood pressure and is produced in response to release of renin from the kidney. Hence, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
Production of plasma protein of blood takes place in the liver.
