Question

describe in brief the function of kidney, ureters, urinary
bladder and urethra

Answer 1

Kidneys are a natural filter of the blood, designed to remove impurities. The ureters carry urine from the kidneys to the urinary bladder. The urinary bladder stores urine, while the Sphincter muscle holds it closed until the person decides to go to the toilet. The urethra carries urine to the outside of the body.

Answer 2

Answer:

Renal artery: The renal artery carries blood to the kidneys from the abdominal aorta. This blood comes directly from the heart and is sent to the-kidneys to be filtered before it passes through the rest of the body. Up to one-third of the total cardiac output per heartbeat is sent to the renal arteries to be filtered by the kidneys. Each kidney has one renal artery that supplies it with blood. The filtered blood then can exit the renal vein.

Kidney: The kidneys perform the essential function of removing waste products from the blood and regulating the water fluid levels. The kidneys regulate the body’s fluid volume, mineral composition and acidity by excreting and reabsorbing water and inorganic electrolytes.

Ureter: The ureter is a tube that carries urine from the kidney to the urinary bladder.’ There are two ureters, one attached to each kidney.

Urinary bladder: The urinary bladder is an expandable muscular sac that stores urine before it is excreted out of the body through the urethra.
