Structure and function of urinary system in the human body
The urinary system
The urinary system is the system or the group of organs that clarifies the blood from the nitrogenous wastes (urea and uric acid), excess salts and excess water. It lies inside the abdominal cavity near the backbone.
The function of the urinary system
The urinary system filters the blood from some excess salts, urea, uric acid, and other waste materials, and it expels these wastes outside the body in the form of urine, The excretory system removes excess, unnecessary materials from the body to prevent the damage and the urinary system rids the body of the wastes produced by the cells.
The structure of the urinary system
The urinary system consists of three parts which are the two kidneys, the two ureters, and the urinary bladder.
The two kidneys are bean-shaped organs that are located on both sides of the backbones, and they are the most important organs of the urinary system.
The function of the two kidneys is the filtration of the blood from some wastes such as urea, uric acid, excess salts, and other waste materials, and they get rid of these wastes in the form of urine.
The two ureters are the two narrow tubes that connect the two kidneys with the urinary bladder. They transfer the excretory materials ( the urine ) from the two kidneys to the urinary bladder.
The urinary bladder is a balloon-like sac that receives the urine from the two ureters, It stores the urine temporarily until it is released outside the body through the urethra.
The urethra is a tube that extends from the urinary bladder and opens outside the body, and it allows urine to pass outside the body.
There is an artery that carries the blood rich in oxygen but contains the waste materials to the two kidneys.
