Dissection is a common practice among high schools in the biology class. With new technology arising‚ there has been many debates that have been presented looking at the pros and cons of such behaviour. Millions of animals are killed annually‚ there are little to no control measures in place‚ and animals suffer for the use of dissection among students. In the United States‚ six million frogs are dissected annually in high schools. An additional amount is used in elementary and universities across

Structure and Function of the Body: Heart Dissection This assignment will describe my personal experience whilst participating in a heart dissection. It will explain the internal and external heart structure and detail the structure of blood vessels in relation to their function. This assignment will also describe what I did‚ saw and felt during my participation. My first thought when the sheep’s heart was given to our group was how fatty it looked to be. At first glance‚ the heart seemed

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. This

I believe the song‚ “Cat People (Putting Out Fire)”‚ is a great connection from song to text‚ between “The Joy Luck Club” and the song‚ because of the way it shows that if you try to solve a problem incorrectly it will cause that problem to get bigger. An example of this is in the scene‚ “Now everyone was standing up and shouting‚ and I heard my mother’s voice crying…If you take your daughter‚ she will become like you… And then with one shout this dark boiling soup spilled forward and fell all over

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
