How is urine is produced

The process of jpe urine is formed: Just as the carbon dioxide is removed from the blood to the lungs , like that the nitrogenous waste i.e urine is to be removed from the body . The basic filtration unit on the kidneys like in the lungs is nephrons a cluster of very thin walled capillaries.A cup shaped and a coiled tube called bowmans capsule collects the filtrate . Each kidney had large numbers of these filtration units called nephrons packed close together.Some substance like amino acid , salts and a good amount of water is reabsorbed in the body.The water reabsorbed depends on how much is there in the body and is to be excreted out.The urine is the. Sent to the urinary bladder.Urine is stored in the urinary bladder.The urine is then passed to the urethra where the urine is removed out of the body.The bladder is muscular as it is under the nervous control.As a result we can hold urine until its urge to urinate

Nephron

The NEPHRON, functional unit of kidney produces the urine, this production of urine undergo the process of ultra filtration in the bowman's capsule, in the selective reabsorption take place in the Glomerulus and the urine is passed through the tubles, then finally the tubular secretion takes place from where the useful substances such as water amino acids are reabsorbed and urine produced through the collecting duct. This pass through the ureter to the urinary bladder where the urine is stored. The urinary blader urge urine to pass through the urethra. This how the urine formation and production take place Hope this may be useful
