What is the internal body cavity?

Definition:

The internal body cavity is the fluid-filled space within an animal's body that holds and protects internal organs.

Details:

- It provides support, cushioning, and protection for vital organs.

- The main body cavity is subdivided into different compartments by mesentery, a membrane that connects organs to the body wall and to each other.

- In mammals, the main internal body cavity is known as the coelom.

- The coelom is further divided into the thoracic (chest) cavity, abdominal cavity, and pelvic cavity. Each of these cavities contains specific organs.

- In some animals, such as arthropods, the main body cavity is known as the hemocoel.

- The hemocoel contains blood and bathes the organs directly, allowing for the transport of nutrients and gases.
