Question

All the functions are performed by kidney except

• A. Regulation of B.P
• B. Regulation of body fluid pH
• C. Secretion of antibodies
• D. Removal of nitrogenous wastes

Answer 1

The correct option is C Secretion of antibodies

The principal function of the kidneys is to help maintain homeostasis by regulating fluid balance and excreting metabolic wastes. However, the kidneys have other functions as well. They produce the enzyme renin, which helps regulate fluid balance and blood pressure. They also produce at least two hormones: erythropoietin, which stimulates red blood cell production, and 1,25- dihydroxyvitamin D3, which stimulates calcium absorption by the intestine. Kidneys are not involved in antibody production or secretion.
