Ventral body cavity

body cavity
The two largest human body cavities are the ventral body cavity, and the dorsal body cavity. The dorsal body cavity includes the cranial cavity, enclosed by the skull and contains the brain, and the spinal cavity, enclosed by the spine and contains the spinal cord The ventral body cavity includes the thoracic cavity, enclosed by the ribcage and contains the lungs and heart; and the abdominopelvic cavity.
The ventral body cavity is a human body cavity that is in the anterior (front) aspect of the human body.

Abdominal cavity

abdominalabdomenabdominal (peritoneal) cavity
In the meninges for example the fluid is cerebrospinal fluid; in the abdominal cavity the fluid contained in the peritoneum is a serous fluid. The abdominopelvic cavity can be divided into the abdominal cavity, enclosed by the ribcage and pelvis and contains the kidneys, ureters, stomach, intestines, liver, gallbladder, and pancreas; and the pelvic cavity, enclosed by the pelvis and contains bladder, anus and reproductive system.
The abdominal cavity is a large body cavity in humans and many other animals that contains many organs.

Coelom

coelomic fluidacoelomatepseudocoelomate
In amniotes and some invertebrates the peritoneum lines their largest body cavity called the coelom. In amniotes and some invertebrates the coelom is the large cavity lined by mesothelium, an epithelium derived from mesoderm.
The coelom is the main body cavity in most animals and is positioned inside the body to surround and contain the digestive tract and other organs.

Serous fluid

serousserumsera
In the meninges for example the fluid is cerebrospinal fluid; in the abdominal cavity the fluid contained in the peritoneum is a serous fluid.
The fluid fills the inside of body cavities.

Thoracic cavity

The dorsal body cavity includes the cranial cavity, enclosed by the skull and contains the brain, and the spinal cavity, enclosed by the spine and contains the spinal cord The ventral body cavity includes the thoracic cavity, enclosed by the ribcage and contains the lungs and heart; and the abdominopelvic cavity.
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia).

Pelvis

The abdominopelvic cavity can be divided into the abdominal cavity, enclosed by the ribcage and pelvis and contains the kidneys, ureters, stomach, intestines, liver, gallbladder, and pancreas; and the pelvic cavity, enclosed by the pelvis and contains bladder, anus and reproductive system.
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis and which primarily contains reproductive organs and the rectum.

Dorsal body cavity

The two largest human body cavities are the ventral body cavity, and the dorsal body cavity. The dorsal body cavity includes the cranial cavity, enclosed by the skull and contains the brain, and the spinal cavity, enclosed by the spine and contains the spinal cord The ventral body cavity includes the thoracic cavity, enclosed by the ribcage and contains the lungs and heart; and the abdominopelvic cavity.
It is one of the two main body cavities, along with the ventral body cavity.

In amniotes and some invertebrates the peritoneum lines their largest body cavity called the coelom. In amniotes and some invertebrates the coelom is the large cavity lined by mesothelium, an epithelium derived from mesoderm.
Flatworms are acoelomates, lacking a body cavity, as are their closest relatives, the microscopic Gastrotricha.

Epithelium

In amniotes and some invertebrates the coelom is the large cavity lined by mesothelium, an epithelium derived from mesoderm.
Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs.

Serous membrane

serosaserosalserous membranes
The visceral layer will form the visceral layer of the serous membranes covering the lungs, heart, and abdominal organs.
The inner layer that covers organs (viscera) in body cavities is called the visceral membrane.

Mesothelium

In amniotes and some invertebrates the coelom is the large cavity lined by mesothelium, an epithelium derived from mesoderm.
Mesothelium derives from the embryonic mesoderm cell layer, that lines the coelom (body cavity) in the embryo.

Oligochaeta

oligochaeteoligochaetesoligochaete worm
Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.

Circulatory system

cardiovascularcirculationcardiovascular system
Their principal body cavity is the hemocoel or haeomocoel of an open circulatory system, often derived from the blastocoel.
Their body cavity has no lining or enclosed fluid.

Potential space

neck space
A body cavity is any space or compartment, or potential space in the animal body.

Central nervous system

Spinal cord

Intraembryonic coelom

Intra-embryonic coelom
Mammalian embryos develop two cavities: the intraembryonic coelom and the extraembryonic coelom (or chorionic cavity).
