To carry blood/wastes to and from the kidneys.
Arteries carry oxygenated blood from the lungs around the body. Veins carry 'used' blood back to the lungs.
The aorta does not play a direct role in the excretory system. The main function of the aorta is to carry oxygenated blood away from the heart and deliver it to the rest of the body. The excretory system primarily consists of the kidneys, which filter waste products from the blood and produce urine.
Veins and arteries are in the circulatory system. Therefore that means they have something to do with pumping blood to cells around the body. So I would say that the role the arteries play in the body is that it carries blood to and from the heart to other parts of the body
it carries the blood through the body
Kidneys play biggest role in fluid balance. They are part of the excretory system.
it excretes waste which is when you deficate (poopoo) through you anus
The heart and the lungs play a major role in the circulatory system. The circulatory system also include the arteries, capillaries, and veins.
They help prevent back flow.
Veins carry blood from the extremities of the circulatory system to the heart.
The excretory system works when you eat food and the bad substances form your food is carried to your kidneys. Then the nephrons purify the blood and the bad watery stuff goes down the ureter and then goes to the bladder. Then, once the bladder is almost filled, the urea goes down the urethra and outside of your body.
The bladder stores urine before it is released from the body via the urethra.
