Anatomy Organ Functions and Locations For Fetal Pigs

Diaphragm

between liver and heart, a sheet of muscle and connective tissue that helps in breathing, separates thoracic cavity from the abdominal cavity

Pericardial sac

surrounds the heart and contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural (lung) cavity

Thymus gland

Located anterior to heart and medial, covers part of trachea, helps regulate the immune system

Lungs

sides of heart, responcible for respiration (expands when breathing in, contracts when breathing out)

How many lobes are in the right lung of a fetal pig?

4

How many lobes are in the left lung of a fetal pig?

3

Trachea

anterior to the esophagus, lower neck, in medial upper chest, connects to lungs., passage for air and protects the respiratory surface from an accumulation of foreign particles

Esophagus

behind trachea, carries food from mouth to stomach

Larynx

an enlarged structure on the trachea, produces sound and vocalizations, prevents aspiration of food

Large intestine

lower abdomen, near small intestine, larger than small intestine., deals with absorption of water, synthesis of certain vitamins, and the collection of waste materials or feces.

Gall bladder

small, attached to the underside of the liver, greenish because it stores bile.

Liver

below heart, above stomach, large organ, makes bile, makes proteins and immune cells, and it filters and breaks down toxic chemicals from blood

Small Intestine

Long organ, but small in thickness, located below stomach, lower abdomen, helps to further digest food coming from the stomach, it absorbs nutrients and water from food so they can be used by the body

Spleen

located near the stomach, a flat organ, deals with producing and maturing new blood cells and eliminating old ones. Blood passes through open sinuses in the spleen, rather than being confined to narrow blood vessels.

Stomach

part of it beneath the liver, near liver, to the side a bit. deals with storage, initiating the breakdown of nutrients, and passing the partially digested food into the small intestine

Heart

surrounded by a pericardial sac, center of upper abdomen, The right side of the heart pumps blood to the lungs, and the left side pumps blood out to the rest of the body, pumps blood

Mesentery

lines the abdominal cavity, thin, transparent sheets of connective tissue containing blood vessels connecting the intestine and other organs

Kidneys

behind intestines, filter waste from the blood and to regulate the blood's salt and water levels, urine is also produced

Urinary bladder

pelvic cavity, low low abdomen, stores urine, can expand

What does Retroperitoneal mean?

occurring behind the peritoneum

What is an example of something that is retroperitoneal?

kidneys, esophagus

What is the peritoneum?

the mucus membrane covering the abdominal cavity
