The correct Answer is:
To determine which statement is correct regarding blood and lymph, we will analyze each option step by step.
### Step 1: Analyze the first statement
- **Statement**: Blood has white blood cells and lymph has red blood cells.
- **Analysis**: This statement is incorrect. Blood contains both red blood cells (RBCs) and white blood cells (WBCs), while lymph primarily contains white blood cells and does not contain red blood cells.
### Step 2: Analyze the second statement
- **Statement**: Blood has white blood cells and red blood cells. Lymph has neither white blood cells nor red blood cells.
- **Analysis**: This statement is also incorrect. While it is true that blood contains both types of cells, lymph does contain white blood cells (specifically lymphocytes). Therefore, the claim that lymph has neither is false.
### Step 3: Analyze the third statement
- **Statement**: Blood has red blood cells and white blood cells. Lymph has white blood cells.
- **Analysis**: This statement is correct. Blood indeed contains both red and white blood cells, and lymph contains white blood cells (lymphocytes). This aligns with the biological understanding of blood and lymph composition.
### Step 4: Analyze the fourth statement
- **Statement**: Lymph has white blood cells and red blood cells. Blood has red blood cells.
- **Analysis**: This statement is incorrect. While lymph does contain white blood cells, it does not contain red blood cells. Blood contains red blood cells, but lymph does not.
### Conclusion
After analyzing all the statements, we find that the correct statement is the third one: "Blood has red blood cells and white blood cells. Lymph has white blood cells."
