Human plasma is the liquid component of blood that makes up more than half (about 55%) of its overall content. It is a clear, straw-colored liquid that carries water, salts, enzymes, hormones, nutrients, and proteins to the parts of the body that need them. Plasma also helps to redistribute water where the body needs it, maintain blood pressure and circulation, regulate body temperature, and remove waste from cells and transport it to the liver, lungs, and kidneys for excretion. Plasma contains important components such as antibodies, clotting factors, and proteins like albumin and fibrinogen. When separated from the rest of the blood, plasma is a light yellow liquid. Plasma is used in therapies for rare diseases, and its proteins and antibodies are used in treatments that can help save the lives of people suffering from burns, shock, trauma, and other medical emergencies. Plasma is donated by healthy donors in a process called plasmapheresis, where plasma is removed from the donors blood and the remaining blood components are returned to the donor.
