1.) They protect delicate organs
2.) They permit significant changes in size and shape of internal organs
Acoelomates, pseudocoelomates and coelomates
The mouth of a cnidarian, such as a jellyfish or sea anemone, opens into a central body cavity called the gastrovascular cavity. This cavity serves both digestive and circulatory functions, as it allows nutrients to be absorbed and distributed throughout the organism's body.
Pisces or fish have true internal body cavity.
A cavity that houses body organs is called a body cavity. The main body cavities are the thoracic cavity, abdominal cavity, and pelvic cavity, which contain organs such as the heart, lungs, stomach, and intestines.
The liver is an organ located entirely in the abdominal cavity. It is one of the largest organs in the body and plays a crucial role in functions like metabolism and detoxification.
The three major functions of the nasal cavity are to warm, moisten, and filter the air that is inhaled. The nasal cavity also helps to detect and process odors through specialized olfactory receptors. Additionally, it contributes to resonating sound during speech.
The pelvic cavity is the most inferior body cavity. The pelvic cavity is bounded by the bones of the pelvis. The pelvic cavity primarily contains reproductive organs, the urinary bladder, the pelvic colon, and the rectum.
Acoelomates, pseudocoelomates and coelomates
The liver is the largest organ in the body cavity. It is responsible for various functions including detoxification, protein synthesis, and production of biochemicals necessary for digestion.
The marrow cavity is responsible for producing and storing blood cells, including red blood cells, white blood cells, and platelets. It also plays a role in storing fat and regulating calcium levels within the body.
The cranial cavity is the empty space inside the skull. It is where the brain is kept. That makes the cranial cavity especially important, since the brain is what controls most of the processes and functions of the body.
The major cavities of the human body are the cranial cavity (housing the brain), thoracic cavity (housing the heart and lungs), abdominal cavity (housing the digestive organs), and pelvic cavity (housing the reproductive organs). These cavities are lined with protective membranes and contain various organs that perform specific functions.
For all mammals, the three functions of fat in the body are to provide energy, to absorb vitamins, and to sustain a normal body temperature.

The brain and the spinal cavity are located in the dorsal body cavity.
