EXCRETORY AND REPRODUCTIVE SYSTEM

Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water and excrete them in the form of urine.

The ureter is a tube that carries urine from the kidney to the urinary bladder. The ureter is about 10 to 12 inches long in the average adult. There are two ureters, one attached to each kidney. The upper half is located in the abdomen and the lower half is located in the pelvic area.

The renal arteries are large blood vessels that carry blood from your heart to your kidneys. Renal is another word for kidney. We have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.

Gynaecology is a branch of medicine that specializes in the care of women during pregnancy and childbirth and in the diagnosis and treatment of diseases of the female reproductive organs.

Urobilin or urochrome is the chemical primarily responsible for the yellow colour of urine. It is a linear tetrapyrrole compound that, along with the related colourless compound urobilinogen, are degradation products of the cyclic tetrapyrroheme.
