Heart Dissection September 30‚ 2012 Introduction/Purpose In this lab experiment‚ I examined a pig’s heart and compared it to a human’s heart. The pig’s heart is very similar to a human’s heart by having the same structures‚ veins‚ valves‚ and chambers. I was unable to perform hands on examination on a human heart so I examined a pig’s heart. I was able to identify major areas of the heart and dissect it to examine the inside chambers and valves.

Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

Aortic Dissection An aortic dissection is a tear in your aorta. The aorta is the main blood vessel that carries blood out of your heart to supply the rest of your body. It comes out of your heart and curves around‚ then goes down through your chest (thoracic aorta) and into your belly (abdominal aorta). The wall of the aorta has inner and outer layers. Aortic dissection occurs most often in the thoracic aorta. This is more likely to happen if the inner layer of the aorta has a weak spot or gets

Tools needed for the dissection of the sheep heart are; 1 scalpel and 3-4 mall probes. Before cutting into the heart‚ trim the fat around the atria and great vessels. Also be sure to identify and explore a few structures/features such as the base and apex of the heart before making any incisions. [pic] You will need to orient the heart so that the vena cava is placed dorsally. The apex of the heart will be inferior to the base. The superior/inferior

Preparing for Dissection The first thing to do when preparing to dissect a shark is to get a pair of gloves so the smell of shark and the raw shark is not touched and on whoever will be dissecting. The next thing to do is get all of the materials that will be needed while dissecting the shark. The things that will be needed are: scalpel‚ tweezers‚ prop‚ pickups‚ scissors‚ and a tube to put the shark in. Then of course the last thing needed before beginning the dissection is the shark.

For my final project in Zoology I choose to write about the Starfish and Mussels we dissected. I chose these because‚ for me‚ these dissections were the most fun! Seeing what was inside of the starfish was nothing I had thought it would be‚ and the mussel is something I eat but usually it is mostly cleaned out by then so it was interesting to see what it looked like before it was cooked. As well as dissecting these animals‚ I was able to learn about how they interact with one another. In this essay
