What is significance of amniotic fluid ?

Options

A. Prevents dessication and helps in body movements of foetus
B. Provides nutrition
C. Helps in gaseous exchange
D. Helps in excretion

Answer

### Step-by-Step Solution:

1. **Definition of Amniotic Fluid**: Amniotic fluid is the liquid that surrounds and protects the developing fetus in the amniotic sac within the uterus.

2. **Prevention of Desiccation**: One of the primary functions of amniotic fluid is to prevent desiccation (drying out) of the fetus. It maintains a moist environment that is crucial for the health of the developing baby.

3. **Facilitating Movement**: Amniotic fluid allows the fetus to move freely within the uterus. This movement is important for the development of muscles and bones.

4. **Cushioning Effect**: The fluid acts as a cushion, protecting the fetus from physical shocks and impacts that may occur during pregnancy.

5. **Temperature Regulation**: Amniotic fluid helps in maintaining a stable temperature around the fetus, providing an optimal environment for its development.

6. **Sex Determination and Health Monitoring**: The composition of amniotic fluid can be analyzed to determine the sex of the fetus and to assess its health. It can reveal genetic disorders and other health issues.

7. **Distinction from Placenta Functions**: While amniotic fluid has several important roles, it is important to note that functions such as providing nutrition, gaseous exchange, and excretion are primarily the responsibilities of the placenta.

8. **Conclusion**: The significance of amniotic fluid lies in its protective, supportive, and diagnostic roles during fetal development.
