fetal pig functions

pinna\*

helps the pig hear by focusing the sound into the middle ear

rostrum\*

the snout

umbilical cord

bringing of food and oxygen to the fetus and the removal of wastes

peritoneum

protects the organs that are within that specific area and contain fluid to allow free flow of movement between organs.

umbilical vein

carries oxygenated blood from placenta to fetus

umbilical arteries

carry deoxygenated blood from fetus to placenta

liver

makes blood cells, produces bile, detox

mesentery

holds the small intestine in place

large intestine

absorption of water, synthesis of certain vitamins, and the collection of waste materials or feces

rectum

help to move digestive wastes (feces) out of the body

cardiac valve

esophagus to stomach, carries food that was eaten to the stomach

pyloric valve

controls the flow of partially digested food from the stomach to the small intestine

gall bladder

stores bile and sends it to the duodenum through the bile duct

bile duct\*

attaches the gallbladder to the duodenum

pancreas

It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as an exocrine gland, secreting pancreatic juice containing digestive enzymes that pass to the small intestine

spleen

destroys, recycles and synthesizes red blood cells

posterior vena cava

brings deoxygenated blood from the body back to the heart and lungs to be reoxygenated

pericardium

the covering of the heart, lining the pericardial cavity which is the sac containing the heart, bathing it in fluid and keeping it separate from the expanding lungs during breathing

thymus gland\*

the site of T lymphocyte (white blood cell) maturation, and thus plays an important role in immunity

lungs

provide a large surface area for the exchange of oxygen and carbon dioxide

trachea

serve as a passageway for air to and from the lungs during inhalation and exhalation

esophagus

carries food from mouth to stomach

carotid arteries

supply blood to the right and left side of the head and neck

jugular veins

bring deoxygenated blood from the head back to the heart

thyroid gland

produces thyroid hormone and also regulates cellular metabolism and calcium levels

larynx

produces sound and vocalizations

epiglottis

Acts as a switch to allow air into the larynx and food into the esophagus

left and right atria

Deoxygenated blood enters the heart at the right atrium via the superior vena cava. After oxygenation, the blood travels back to heart via the pulmonary veins and enters the left atrium.

left and right ventricle

The right side of the heart pumps blood to the lungs (pulmonary circulation), and the left side pumps blood out to the rest of the body (systemic circulation)

anterior vena cava

brings blood to the right atrium from the anterior part of the body

pulmonary artery

carry oxygenated blood to the lungs

pulmonary veins

carry deoxygenated blood to the lungs

aorta

pumps the blood out to the body

dorsal aorta

carry blood from the aortic arch to smaller arteries

coronary arteries

supplies oxygenated, nutrient-rich blood to the ventral portion of the heart

kidneys

to filter waste from the blood and to regulate the blood's salt and water levels

ureter

carries urine down from the kidney to the bladder

urinary bladder

Urine is stored in the urinary bladder, an expandable, muscular sac, until it is excreted from the body

testes

the site of sperm production and maturation

vas deferens

transports sperm to urethra

ovaries

the site of oocyte production and maturation

oviducts

acts as the site of fertilization

uterus

acts as part of the birth canal

small intestine\*

digestion of food
