True-False Quiz 3 - Fetal Pig Dissection:
True / False

A mid-ventral incision is one made in the middle of the back of the fetal pig.

Tweezers are more specifically called forceps.

The external ear of the fetal pig is called the pinna.

Both male and female fetal pigs have teats.

The fetal pig has a gallbladder which is used to purify the blood.
True / False

The liver of the fetal pig will eventually produce bile for the emulsification of fats.

After the ventral side of the fetal pig is opened, 2 major body cavities are observed: the anterior abdomen and the posterior thorax.

The heart of a fetal pig is enclosed in the perineal sac.

In most fetal pigs, the testes are found inside the abdomen because they haven't descended yet. Small bumps (the testes) may be observed through the skin of the lower abdomen.

A tongue-shaped brownish organ lateral to the stomach of the fetal pig is called the spleen.
True / False

The duodenum of the fetal pig is a section of large intestine.

Some fetal pigs are injected with a dye so that the arteries are stained red and the veins are stained blue.

The posterior vena cava (post cava, inferior vena cava) returns deoxygenated blood to the left atrium of the fetal pig.

The carotid arteries of the fetal pig carry deoxygenated blood into the head region.

The trachea of the fetal pig is a rigid white-coloured tube that lies under (dorsal to) the esophagus.
True / False

The ovaries of a fetal pig are easily located deep in the abdomen as pea-sized organs, usually brown in colour, and connected to twisting tubes called the oviducts.

A gland that looks a bit like cottage cheese or cauliflower and lies inferior to (beneath) the stomach of the fetal pig is the pancreas. This gland will be involved in blood sugar regulation.

Two glands that can be easily destroyed in a rushed dissection of the fetal pig are found in the neck and chest region. These are the thymus and the adrenal gland.

If you dissect deep into the abdomen of the fetal pig, you will certainly find two quite large organs embedded in fat and connective tissue. These are the kidneys.

The term "dissection" is given to the cutting open/exploration of dead organisms. The term "vivisection" is given to the cutting open/exploration of live organisms.
