Blood Basics

Our blood is a living tissue with a variety of critical functions: It delivers oxygen and nutrients to our organs, fights infections and creates blood clots, preventing us from bleeding excessively when a blood vessel is damaged. ...

Plasma also carries the solid part of our blood -- white blood cells, which work to destroy viruses and bacteria; red blood cells, which carry oxygen through the body; and platelets, which help clotting.
