What are the spaces in the body that contain organs?

What are the spaces in the body that contain organs?

A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity.

Which body cavity Do you feel like contains the most vital organs?

The abdomen contains many vital organs: the stomach, the small intestine (jejunum and ileum), the large intestine (colon), the liver, the spleen, the gallbladder, the pancreas, the uterus, the fallopian tubes, the ovaries, the kidneys, the ureters, the bladder, and many blood vessels (arteries and veins).

What are the main body cavities?

Body Cavities The two main cavities are called the ventral and dorsal cavities. The ventral is the larger cavity and is subdivided into two parts (thoracic and abdominopelvic cavities) by the diaphragm, a dome-shaped respiratory muscle.

How does a midsagittal plane divide the body?

Definition. The midsagittal plane or median plane divides the body into two parts. It vertically splits any object or organism into two relatively equal halves – left and right. In humans, each of the two bisected divisions includes half of the head, thorax, abdomen and genitals, one arm and one leg.

What does thoracic cavity contain?

[2] The thoracic cavity contains organs and tissues that function in the respiratory (lungs, bronchi, trachea, pleura), cardiovascular (heart, pericardium, great vessels, lymphatics), nervous (vagus nerve, sympathetic chain, phrenic nerve, recurrent laryngeal nerve), immune (thymus) and digestive (esophagus) systems.

Which body cavity contains the peritoneum?

the abdominal cavity
The peritoneum is the serous membrane that lines the abdominal cavity. It is composed of mesothelial cells that are supported by a thin layer of fibrous tissue and is embryologically derived from the mesoderm.

What does the cranial cavity contain?

Cranial. The cranial cavity is the anterior portion of the dorsal cavity consisting of the space inside the skull. This cavity contains the brain, the meninges of the brain, and cerebrospinal fluid.

Which of the following cavities are separated by the diaphragm?

The diaphragm is a thin dome-shaped muscle which separates the thoracic cavity (lungs and heart) from the abdominal cavity (intestines, stomach, liver, etc.).

What are imaginary anatomical dividing lines that separate body structures?

planes. imaginary, anatomical dividing lines useful in separating body structures. posterior. located behind or at the back, opposite to anterior. proximal.

Which organs are located in the median midsagittal section of the body?

In the soft tissues of the head, the median plane separates the brain into its two hemispheres, together with the near-equal separation of nasal cavity, tongue, pharynx, and larynx, the latter of which can be seen below.
