Explanation:
The kidney is an important organ of the human body responsible for various functions. One of its primary functions is excretion, which involves filtering the blood to remove waste products and excess water and electrolytes from the body.
The nephron is the structural and functional unit of the kidney responsible for the excretory function. It is a complex structure consisting of a glomerulus, tubules, and collecting ducts that work together to filter and remove waste products from the blood.
The kidney also plays a regulatory function in the body, maintaining the balance of water, electrolytes, and acid-base levels in the blood. This function is also performed by the nephrons, which reabsorb or excrete various substances to maintain the balance of the body's internal environment.
However, the kidney does not have neurons for the excretory function. Neurons are specialized cells of the nervous system responsible for transmitting signals throughout the body. Instead, the kidney has specialized cells called juxtaglomerular cells that regulate blood pressure and the production of hormones such as renin.
Therefore, option B is the correct answer as the kidney has nephrons for the excretory function.
Summary:
- The kidney is responsible for excretion and regulatory functions in the body.
- The nephron is the structural and functional unit of the kidney responsible for the excretory function.
