Fetal Pig - External Anatomy
External Anatomy/General Internal Anatomy/Integumentary System:
Two characteristics that are unique to mammal: hair located on the surface of the skin and nipples for the ejection of milk.
- the opening in the body through which food can pass and enter the digestive system, oxygen may enter the respiratory system, and carbon dioxide may leave the respiratory system. The mouth consists of the tongue, lips, teeth, and gums.
- The tongue is a movable organ in the mouth that helps move around food to be chewed when eating and to taste.
- the small white structures in the mouth that are held in place by the gums. Teeth are used in chewing, tearing, and scraping.
The teeth of the pig suggest that its diet comprise mainly of plants but may also contain meats.
- the hard bony part in the front of the roof of the mouth.
- the soft tissue part in the back of the roof of the mouth. The soft palate is responsible for the shutting off of the nasal passages during swallowing.
- tiny nerve endings on the upper surface of the tongue that allow us to recognize a variety of different tastes.
An animal that walks on its digits, better known as toes, uses digitigrade locomotion. Humans on the other hand use plantigrade locomotion because they walk with the soles of their feet planted to the ground.
- The two sacs of tissue that contain the testicles.
- the external opening of the rectum in which feces are expelled during defecation.
- the opening in which wastes and reproductive fluids are excreted and expelled out of the body.
- the flap of tissue covering the urogential opening.
- best known as the nipple, it is mainly used in female mammals for the excretion of milk.
- the tube connecting the fetus to the placenta so that nutrients and other necessary molecules can be transported to and from the mother and her offspring.
- There are usually two and they transport deoxygenated blood from the fetus to the placenta.
- a blood vessel that provides oxygen-rich blood from the placenta to the fetus.
Carbon-dioxide would be found in the blood of the umbilical arteries. Oxygen would be found in the blood of the umbilical vein.
