RBC Full Form in Biology

RBC = Red Blood Cell (or Red Blood Corpuscle)

In medical terminology, RBCs are scientifically known as Erythrocytes (from Greek erythros meaning red, and kytos meaning cell).

• Shape: Mature RBCs in humans have a unique biconcave disc shape (like a donut without the hole fully punched out). This shape maximizes surface area for gas exchange.
• No Nucleus: To make maximum room for oxygen, mature mammalian RBCs do not have a nucleus or mitochondria.
• Function: Their primary job is to carry oxygen from the lungs to the body's tissues and carry carbon dioxide back to the lungs.
• Haemoglobin: They contain an iron-rich protein called Haemoglobin, which binds to oxygen and gives blood its characteristic red colour.

• Production: RBCs are continuously produced in the bone marrow in a process called erythropoiesis.
• Lifespan: A typical human red blood cell lives for about 120 days.
• Destruction: Old or damaged RBCs are destroyed primarily in the spleen (often called the 'graveyard of RBCs') and the liver.
