Answer:
Execretion: The removal of unwanted and unused metabolic wastes from our body is know as excretion.
Nephron: Bundle of nerves is known as nephron.
Answer:
Ques.What is excretion?
Ans.Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin.
Excretion is an essential process in all forms of life.
For example, in mammals urine is expelled through the urethra, which is part of the excretory system.
Ques.Describe the structure of nephron with diagram.
Ans.A nephron is the basic structural and functional unit of the kidney. Its chief function is to regulate water and soluble substances by filtering the blood, reabsorbing .
There are about 1,000,000 nephrons in each human kidney.
This nephron contains a loop of Henle, so it is a mammalian nephron. While the loop of the nephron is special to mammals, the rest of the structure is seen in all vertebrate animals. The glomerulus is the net of capillaries inside of the glomerular capsule (aka Bowman’s capsule). While the picture shows the glomerular capsule and the rest of the renal tubule look to be the same in the graphic below, they are in fact composed of a wide variety of cell types, intended to extract and retain certain chemicals within the tubules.
Each nephron consists of one main interlobular artery feeding a single renal tubule. Each kidney in a vertebrate has hundreds to millions of nephrons, each of which produces urine and sends it to the bladder. The cells in each nephron are arranged so that the most concentrated cells are at the bottom of the nephron, while the cells at the top are less concentrated. The cells near the exit of the nephron are the most concentrated, and therefore extract as much water as possible from the ultrafiltrate before it is sent to the bladder.

Well....
