Excretory waste is eliminated through the excretory system in response to Many parts of the body play a role in this process, such as sweat glands, the liver, the lungs and kidneys. Two kidneys are present in every human being. There are three sections in each kidney There are three parts of the renal pelvis the renal cortex, the renal medulla and the renal medulla. Through the renal artery, which is divided into several afferent arteries, blood is transported to the kidney. The arterioles lead to Bowman’s capsules of the nephrons, where wastes are filtered out of the blood by pressure.
Moreover, there are peritubular capillaries that surround the nephron so that substances can be taken into and out of It is the outer layer of the kidney that is known as the renal cortex, while the inner layer is its medulla. In the renal pelvis, the ureter carries urine from the kidney to the outside world. The only body part with a bladder is the ureter, which provides the urine with a path to the urinary bladder, which expands In the urethra, urine is expelled from the body through the urethra.
