What is the main function of cortical nephrons ?
Reabsorption ,filtration ,excretion
Nephrons have two lengths with different urine concentrating capacities: long juxtamedullary nephrons and short cortical nephrons. The four mechanisms used to create and process the filtrate (the result of which is to convert blood to urine) are filtration, reabsorption, secretion and excretion.
They are present by 70% of total Nephrons they are actively working when there is proper water level in body because they are having short loops of henle and water reabsorption is less through them
