Bleeding

Well done! Let’s talk about blood …

Blood is circulated around the body through blood vessels by the pumping action of the heart. In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from the tissues to the lungs to be exhaled.

Its function is to form blood clots when bleeding so as to stop the body from losing too much blood.
