nephron of the kidney- structure which carries out the filtration of our blood
resulting in two things:
- filtered blood (clean blood) with waste product
-urine (largely composed of water, salt ,NACL, MGCL), urea (nitrogen waste of the body very toxic)
bowmans capsule- filtration process begin (ultrafiltration), filtration of molecules
-the filtration of blood begins with bloof arriving in the kidney, in the nephron entering the afferent arteriole (blood enter), high pressure
- the blood vessel coming out has a smaller and narrower bloog vessel
- the blood vessels pressure increases in the glomerulus
- the high pressure forces the liquid within the blood (plasma- containing water, salts, amino acids, glucose, urea) forcing it outside the bowmans capsule
- when the plasma is forced in to the bowmans capsule, its called filtrate, and since its in the glomerulus its called the glomerulus filtrate
- the blood has been filtered by pressure due to the smaller restricted diameter of the blood vessel [efferent arteriole] generating a the pressure to be high
