Valuable Substances in Filtrate are Returned to the Blood Through

Question

Valuable substances in filtrate are returned to the blood through what process?
A) filtration
B) reabsorption
C) secretion
D) excretion

Accepted Answer

Reabsorption is the process by which valuable substances such as glucose, amino acids, and ions are returned to the blood from the filtrate in the nephron. This process is crucial for maintaining homeostasis and preventing the loss of important nutrients and electrolytes from the body. Filtration is the initial step in urine formation, where blood is filtered through the glomerulus in the nephron. Secretion is the process by which wastes and excess ions are removed from the blood and added to the urine for excretion. Excretion is the process by which urine is eliminated from the body through the urinary system.
