What are the two parts of the kidney?
The structural and functional unit of the kidney is called nephron. It consists of two main parts viz. the glomerulus and the tubular system. The glomerulus is composed of Bowmans capsule and a tuft of leaky blood vessels encapsulated by the Bowmans capsule. The primary purpose of the glomerulus is filtration. The leaky vessels filter into the glomer ulus almost all the water, electrolytes, small proteins, nutrients such as sugar etc and excretory products such as urea etc. The filtration are dependent on the size and charge of the particles. The average pore size is 8 mm and hence particles of only smaller size will pass through. Also, the basement membrane carries a negative charge, hence preventing negatively charged particles from passing through. The tubular system is responsible for reabsorption of most of the water, electrolytes, nutrients as well as excretion of the remaining nutrients by means of secretion into the tubules. These tubules are responsible for the concentration of urine.
