filtration takes place only at glomeruli part of nephron and nowhere else.
Glomerulus (Renal Corpuscle)
Filtration, tubular reabsorption, tubular secretion
The filtration membrane in the nephron is formed by the fenestrated endothelium of the glomerular capillaries, the glomerular basement membrane, and the podocytes of the Bowman's capsule that wrap around the capillaries. These structures work together to selectively filter and prevent the passage of larger molecules like proteins into the urine while allowing smaller molecules to be filtered.
Urine formation in the kidney
The filtrate from Bowman's capsule first travels to the proximal tubule of the nephron.
filtration of blood
filtration of blood
The kidney removes impurities from the blood in two ways. These processes are known as ultra filtration and selective reabsorption. The active component of the kidney involved with filtration is the nephron.
glomerular capsule.
The blood pressure in these capillaries is relatively high, so pressure filtration occurs. The blood's plasma and small waste materials and chemicals (the contents of the closet) are pushed out of the blood into the nephron, leaving behind larger proteins, nutrients, and blood cells.
The cup-shaped part of the nephron is called the renal (or Bowman's) capsule. It is located at the beginning of the nephron and surrounds the glomerulus, which is a network of capillaries. The renal capsule helps in the filtration of blood and the formation of urine.
The hollow bulb at the proximal end of the nephron is called Bowman's capsule. It is a cup-like structure that surrounds the glomerulus and is responsible for filtering blood to initiate the process of urine formation in the kidneys.
