Blood Comes Out When I Urinate - SPORTS

Blood is a specialized fluid that constantly flows throughout your body. It’s made of plasma, red blood cells, white blood cells and platelets. It has four main components: plasma, red blood cells, white blood cells, and platelets.

The blood that runs through the veins, arteries, and capillaries is known as whole blood—a mixture of about 55% plasma and 45% blood cells. About 7% to 8% of your total body weight is blood.
