Draw the diagram of nephron. Recognize the parts of glomerulus and tubular reabsorption. Write how those actions take place.

Explanation

1. Glomerular filtration : Blood flows inside the glomerulus under the influence of pressure due to the broadness of afferent arteriole. As a result it undergoes pressure .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.
