Question

About dialysis process

Answer 1

Hey mate,

Good Morning :-)

Dialysis is an artificial process used for filtering the blood in the human body. This treatment is introduced to a patient when their kidneys could no longer perform this function. It helps to get rid of extra body’s wastes and controls the blood pressure.

The word Dialysis is derived from the Greek word meaning dissolution. During dialysis waste and surplus water are eliminated from the blood and is used predominantly as a standby for the loss of kidney power in individuals with kidney breakdown.

Dialysis is used for people with a critical disorder in kidney functioning  (grave kidney damage, previously severe renal failure) or advanced but constantly deteriorating kidney function—a condition branded as chronic kidney disease stage 5 (end-stage renal failure or formerly chronic renal disease).

This treatment may continue for months or years, in comparison to severe kidney injury which is not typically reversible and dialysis is considered as a sustaining measure until the kidney transplant is performed for natural blood purification in the human body.

Dialysis functions on the ultrafiltration of fluid through a semipermeable membrane and concept of the dissipation of solutes. Diffusion is a characteristic of materials in water that has the tendency to flow against a concentration gradient.

Blood runs on one flank of the semi-permeable film, and a dialysate, or distinct dialysis fluid, flows on the opposite flank. A selectively permeable layer is a skinny membrane of material that comprises of pores of different sizes or holes. Minor solutes and fluid flow through the layer, but the membrane stops the path of bigger substances (for instance, large proteins, red blood cells). This imitates the filtering procedure that happens in the kidneys when the blood moves into the kidneys and the bigger substances are divided from the minor ones in the glomerulus.

Hope it helps you :-)

Answer 2

dialysis is a process of seperating the particles of colloid from those of crstalloids by means of diffusion through a suitable membrane

its based on the principle of the fact that colloidal particles can't pass through the parchment

guys hope my ans hopeful to u
