OBSERVATION OF PIG HEART
Using the directions provided in this lab packet dissect the pig's heart. Identify the structures that are listed
below. From your text pages 342-347 identify the function of each of the structures and fill the information in on
the appropriate space. Each team of two will then bring their heart and their lab sheet to the front table for an
oral quiz. You and your partner will be asked to demonstrate the proper pathway that blood takes through the
heart, naming the structures as you progress. You will also be asked to describe how the heart creates this one
directional flow.

In the space below describe how the heart maintains a one directional flow of blood which leads to and from the
lungs and then to the body and back to the heart once again. Explain which areas contain oxygenated blood and
which areas contain deoxygenated blood.
Explain how the coronary circulation provides the heart muscle (myocardium) with necessary nutrients and removes
waste products.

occurs in the capillary
Observe the slides of "artery, vein, and capillary. Diagram a section of the wall of the vein and artery. Label the
parts discussed in the textbook. Next diagram the entire capillary as shown on the slide. Finally diagram an
atherosclerotic artery showing a comparison of the opening or lumen.

In the space below discuss what causes
atherosclerosis, how it damages the blood vessel,
and what changes it causes in the physiology of the
blood flow. Research information in classroom or
library resources.
