Process of formation of blood is

Options

A. Haemolysis
B. Plasmolysis
C. Haemopoiesis
D. Haemoneogenesis.

Answer

### Step-by-Step Text Solution:

1. **Understanding Blood Composition**: Blood is classified as a connective tissue and consists of two main components: a fluid part known as blood plasma and a cellular part that includes various blood cells (like red blood cells, white blood cells, and platelets).

2. **Defining Hemopoiesis**: The process responsible for the formation of blood cells and their components is called hemopoiesis (or hematopoiesis). This is the correct term for the formation of blood.

3. **Differentiating Other Terms**:
- **Hemolysis**: This term refers to the rupture or breakdown of red blood cells (RBCs), which is not related to the formation of blood.
- **Plasmolysis**: This term describes the contraction of the protoplast in plant cells due to the loss of water, which is also not relevant to blood formation.
- **Hemoneogenesis**: This term is not commonly used and does not refer to the process of blood formation.

4. **Location of Hemopoiesis**: Hemopoiesis primarily occurs in the red bone marrow, which is located in the epiphysis of long bones and in flat bones such as the ribs, cranial bones, vertebrae, and pelvis.

5. **Conclusion**: The correct answer to the question regarding the process of blood formation is hemopoiesis.
