Detailed explanation-1: -Coelom. In amniotes and some invertebrates the coelom is the large cavity lined by mesothelium, an epithelium derived from mesoderm. Organs formed inside the coelom can freely move, grow, and develop independently of the body wall while fluid in the peritoneum cushions and protects them from shocks.

Detailed explanation-2: -The abdominal cavity holds digestive organs and the kidneys, and the pelvic cavity holds reproductive organs and organs of excretion.

Detailed explanation-3: -“The coelom is the fluid-filled body cavity present between the alimentary canal and the body wall.” The true coelom has a mesodermal origin. It is lined by mesoderm. The peritoneal cavity present in the abdomen and similar spaces around other organs such as lungs, heart are parts of the coelom.

Detailed explanation-4: -The coelom (or celom) is the main body cavity in most animals and is positioned inside the body to surround and contain the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as molluscs, it remains undifferentiated.

Detailed explanation-5: -The coelom is the fluid-filled body cavity present between the alimentary canal and the body wall. The coelom is lined by mesoderm on both the sides, towards the body wall and towards the gut. Humans have a coelom and are known to be eucoelomates (Animals that have a true coelom).
