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 |
Statement |
| |
|
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 |
Statement |
| |
|
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 |
Statement |

|
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.
