Introduction
The dissection of the fetal pig in the laboratory is important because pigs and humans have the same level of metabolism and have similar organs and systems. Also, fetal pigs are a byproduct of the pork food industry so they aren't raised for dissection purposes, and they are relatively inexpensive.
Procedure - as in the text book
Purpose:
The purpose of such activity is to dissect the fetal pig and observe various organs.
Materials:
Safety goggles
String
Dissecting pins
Lab apron
Scalpel
Scissors
Dissecting gloves
Hand lens
Ruler
Preserved Pig
Dissecting Tray
Forceps and probe
Observations
Using a ruler, measure the length of the pig from the snout to the tail. Use graph to estimate the age of the fetal pig.
30cm = 12 days old
Locate the liver ...
... are dorsal and ventral, although the dorsal mesentery is often interrupted and moved to one side or the other with the organs and the ventral mesentery is reduced to the membranes of the liver and bladder. Mesenteries running from organ to organ are usually called ligaments.
D) Why does the left ventricle contain more muscle than the right ventricle?
The left ventricle is much more muscular than the right as it has to pump blood around the entire body, which involves exerting a considerable force to overcome the vascular pressure. As the right ventricle needs to pump blood only to the lungs, it requires less muscle.
E) Why do the lungs feel spongy?
When we breathe in, air
