### Red Blood Cells (RBCs) - Full Details Red blood cells (RBCs), also known as **erythrocytes**, are the most abundant type of blood cell in the human body and play a crucial role in transporting oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs. Here’s a detailed overview of RBCs: ### 1. ** Structure and Composition** - **Shape**: RBCs have a unique **biconcave disc shape**. This shape increases the surface area for gas exchange and allows RBCs to deform, which helps them pass through narrow capillaries. - **Size**: The average diameter of a red blood cell is around **7–8 micrometers**. - **Membrane**: The outer membrane of RBCs is composed of a lipid bilayer embedded with proteins, including **glycophorin** and **spectrin**, which contribute to the cell's flexibility and shape. - **Cytoplasm**: The cytoplasm of RBCs is packed with **hemoglobin**, a protein responsible for oxygen and carbon dioxide transport. ### 2. ** Functi...
