Features of plasma
- This extracellular fluid matrix is a connective tissue carrying white blood cells, platelets, red blood cells, hormones, waste materials and digested food.
- Plasma comprises about 55% of blood, appearing as a straw-coloured fluid, chiefly composed of water while carrying other particles.
- It imparts the fluid consistency to blood supplying all the essential substances and nutrients such as oxygen, sugar etc while carrying away wastes from the cells which over time is flushed out of the body through faeces, urine, lungs, sweat.
- In addition to this, blood also contains agents that help in blood clotting thus preventing excess loss of blood.
