This protects the fetus from injury. it also helps to regulate the temperature of the fetus.

Detailed explanation-2: -Amniotic fluid surrounds the growing fetus in the womb and protects the fetus from injury and temperature changes. It also allows for freedom of fetal movement and permits musculoskeletal development.

Detailed explanation-3: -Amniotic fluid is present from the formation of the gestational sac. Amniotic fluid is in the amniotic sac. It is generated from maternal plasma, and passes through the fetal membranes by osmotic and hydrostatic forces. When fetal kidneys begin to function around week 16, fetal urine also contributes to the fluid.

Detailed explanation-4: -What is the pericardium? The pericardium is a thin sac that surrounds your heart. It protects and lubricates your heart and keeps it in place within your chest. Problems can occur when the pericardium becomes enflamed or fills with fluid.
