which component of the blood transports carbon dioxide and urea in the body?
The component of the blood that transports carbon dioxide and urea in the body is the plasma.
Plasma is the liquid component of blood that makes up about 55% of its total volume. It is a colorless, watery fluid that carries various substances, including carbon dioxide and urea, throughout the body.
Carbon dioxide is a waste product of cellular respiration and is produced by cells as they break down glucose for energy. It is then transported from the cells to the bloodstream, where it dissolves in plasma. The plasma carries the carbon dioxide to the lungs, where it is exchanged for oxygen during the process of respiration.
Urea, on the other hand, is a waste product of protein metabolism. It is produced in the liver and transported to the kidneys, where it is filtered out of the blood and excreted in the urine. The plasma carries urea from the liver to the kidneys, allowing for its elimination from the body.
In summary, the plasma component of the blood plays a crucial role in the transportation of waste products like carbon dioxide and urea, ensuring their proper elimination from the body.
