Question

Materials are returned to the blood from the filtrate by which process?

Answer 1

Reabsorbtion is a process in which materials such as nutrients, water, glucose and waste products are returned to the blood stream.

Step-by-step explanation:

Materials are removed from the process of filtration which occurs in the kidneys. Materials such as glucose ,water, salts and waste materila like urine are removed from the blood and only glucose, vitamins and some amount of water and salts are added to the blood while urine and extra water and salts are moved to the excretory system.

Answer 2

Answer: REABSORPTION

Explanation: Reabsorption or tubular reabsorption is one of the processes involved in urine formation,the other two(2) being ultra filteration and and active secretion.

Reabsorption takes place mainly in the proximal convulated tubule of the nephron, nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration re-enter the blood from the renal tubules,moving solutes out of the filtrate and back into the bloodstream.these solutes that are moved back into the bloodstream goes back into circulation alongside with the blood because it is needed for the normal functioning of the body system and maintanance of homeostasis.

In a situation where tubular reabsorption does not occur as a result of certain conditions like hyposecretion and diabetes insipidus,there will be imbalance of ions in the body as a result of useful ions leaving the body via urine and the body is left with ion deficiency.
