Parts and their functions

• Whole blood (संपूर्ण रक्त) — Looks uniform — blood is a colloid; its cells do not settle on standing.
• Centrifugation (अपकेंद्रण) — Spinning at high speed pushes heavier particles outward — to the bottom of the tube.
• Plasma (top) (प्लाज़्मा (ऊपर)) — The lighter, straw-coloured liquid part.
• Platelets and white blood cells (प्लेटलेट्स और श्वेत रक्त कोशिकाएँ) — A thin middle layer.
• Red blood cells (bottom) (लाल रक्त कोशिकाएँ (नीचे)) — Heaviest, so they collect at the bottom. Blood banks store these components separately.
