2. **Identifying the Liquid Component**: The liquid part of blood is known as plasma. Plasma is primarily composed of water, salts, and proteins.

3. **Identifying the Cellular Components**: The cellular components of blood include:
- Red Blood Cells (RBCs), also known as erythrocytes, which are responsible for transporting oxygen.
- White Blood Cells (WBCs), also known as leukocytes, which play a crucial role in the immune response.
- Platelets, also known as thrombocytes, which are essential for blood clotting.

4. **Combining Components**: Blood is made up of plasma along with these cellular components (RBCs, WBCs, and platelets).

5. **Conclusion**: Therefore, the complete composition of blood is plasma plus red blood cells plus white blood cells plus platelets.
