explained in short about four organs of human excretory system?
Answers
Answer:
Explanation:The Excretory system is responsible for the elimination of wastes produced by homeostasis. There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. Every human has two kidneys.
Answer:
Every living organism generates waste in its body and has a mechanism to expel it. In humans, the excretory system takes care of waste generation and elimination. It comprises of the following structures:
2 Kidneys
2 Ureters
1 Urinary bladder
1 Urethra
Kidneys are the main organ of the human excretory system. Also, every individual has a pair of kidneys. They are located one on each side of the spine at the level of the liver. Kidneys are divided into three regions. Namely, the renal cortex which is the outer layer. Next, the renal medulla which is the inner layer. And lastly, the renal pelvis which carries the urine from the kidney to the ureter.
There is one ureter that comes out of each kidney as an extension of the renal pelvis. It is a thin muscular tube that carries urine from the kidneys to the bladder.
Urinary Bladder
The bladder is a sac-like structure. And a smooth muscle layer lines it. It stores the urine until micturition. Furthermore, Micturition is the act of expelling urine from the body. The bladder receives urine from the ureters, one from each kidney. In addition, the level of placement of the bladder in the body differs in men and women.
Urethra
The urethra is a tube that arises from the urinary bladder. Its function is to expel the urine outside by micturition. In addition, it is shorter in females and longer in males. Furthermore, in males, it functions as a common path for sperms and urine. Also, sphincter guards the opening of the urethra.
