Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The process that reduces the volume of the kidney filtrate and returns substances (water, glucose, amino acids) to the blood.
A
reabsorption
B
perspiration
C
excretion
D
transport
Explanation: 

Detailed explanation-1: -Together these processes complete the transformation of the glomerular filtrate into urine. Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream.

Detailed explanation-2: -Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced. A high ADH level causes the body to produce less urine. A low level results in greater urine production.

Detailed explanation-3: -Most of the reabsorption of solutes necessary for normal body function such as amino acids, glucose, and salts takes place in the proximal part of the tubule. This reabsorption may be active, as in the case of glucose, amino acids, and peptides, whereas water, chloride, and other ions are passively reabsorbed.

Detailed explanation-4: -Reabsorption is the movement of water and solutes from the tubule back into the plasma. Reabsorption of water and specific solutes occurs to varying degrees over the entire length of the renal tubule. Bulk reabsorption, which is not under hormonal control, occurs largely in the proximal tubule.

Detailed explanation-5: -Filtration involves the transfer of soluble components, such as water and waste, from the blood into the glomerulus. Reabsorption involves the absorption of molecules, ions, and water that are necessary for the body to maintain homeostasis from the glomerular filtrate back into the blood.
