    Certainly! Blood consists of several components, including: 1. **Red Blood Cells (RBCs or erythrocytes):** Responsible for carrying oxygen from the lungs to the rest of the body and transporting carbon dioxide back to the lungs to be exhaled. 2. **White Blood Cells (WBCs or leukocytes):** These cells are part of the immune system and help in fighting infections and diseases. There are different types of WBCs, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with its specific role in defending the body. These two types of cells are the primary cellular components of blood, along with platelets, plasma, and various proteins, ions, and nutrients essential for bodily functions.
