Draw the diagram of nephron and recognize the parts of glomerulus and tubular re-absorption. Write how those actions take place.
1) Glomerular filtration :
Blood flows iriside the glomerulus under the influence of
pressure due to the broadness of afferent arteriole. As a result it undergoes pres¬sure filtration or ultrafiltration. Waste molecules, nutrient molecules and water are filtered out and enter the Bowman’s capsule. .
2) Tubular reabsorption
: The peritubular capillaries around proximal convoluted tubule reabsorb all the useful components of primary urine such as glucose, amino acids, vitamin C, potassium, calcium, sodium chlorides and 75% of water.
