Question

Ultrafiltration, Excretion, Reabsorption,

Secretion​

Answer 1

Answer:

Ultrafiltration :- Ultrafiltration is the removal of fluid from a patient and is one of the functions of the kidneys that dialysis treatment replaces.

Excretion :- Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin.

Reabsorption :- Being absorbed again. For example, the kidney selectively reabsorbs substances it has already secreted into the renal tubules, such as glucose, protein, and sodium.

Secretion :- production and release of a useful substance by a gland or cell; also, the substance produced. In addition to the enzymes and hormones that facilitate and regulate complex biochemical processes, body tissues also secrete a variety of substances that provide lubrication and moisture.

Answer 2

1. Ultrafiltration:- (UF) is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density. Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane.
2. Excretion:- is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell.
3. Reabsorption: Being absorbed again. For example, the kidney selectively reabsorbs substances it has already secreted into the renal tubules, such as glucose, protein, and sodium. These reabsorbed substances are returned to the blood.
4. Secretion:- process by which substances are produced and discharged from a cell, gland, or organ for a particular function in the organism or for excretion.
