Blood Components

Blood is made up of several key components: 1. **Red Blood Cells (RBCs)** - These cells transport oxygen from the lungs to the body and carry carbon dioxide back for exhalation. 2. **White Blood Cells (WBCs)** - These cells are part of the immune system, helping to fight infections and protect the body against diseases. 3. **Platelets** - These small cell fragments are crucial for blood clotting, preventing excessive bleeding when injuries occur. 4. **Plasma** - This yellowish fluid contains water, salts, enzymes, hormones, and waste products, serving as a transport medium for the blood components.
