System Differentiation During Fetal Pig Dissection Abstract This report represents an in depth biological study of the sus scrofa and its internal organs located in the ventral body cavity. The purpose of this lab is to compare and contrast the functions of organ systems of humans and fetal pigs‚ primarily those contained within the ventral body cavity‚ which includes both thoracic and abdominal cavities. Also‚ to implement new skills such as dissection and the use of a scalpel as well as other

deGrouchy Mrs. Psitos Math IMP 2H 18 December 2007 Growth of Rat Populations This POW is about the growth of a rat population over a year. Two rats‚ one male and one female‚ are put on an island that has ideal conditions for rats. The female rat has a litter of six rats the first day‚ and will have a litter every forty days after that. There are three important things to remember‚ and they are that the number of rats in every litter is six‚ three females and three males. Secondly‚ every

Mammalian Brain Dissection Purpose: The purpose of dissecting the sheep brain is to learn the structure of the brain. We must learn a brains structure to help us learn its functions‚ because they are very important and part of the Central Nervous System. We must learn the Central Nervous System to learn how it communicates between different parts of the body and the body’s interactions with the environment because it is a California standard. Analysis Questions: 1.) What observable features

Introduction The purpose of this lab is to be able to trace the flow of blood through both the mammalian and the shark heart. Learn all the major structures of the body systems of the shark and functions of certain structures as well as for the rat. Understand the terms of retroperitoneal‚ ovoviviparous‚ oviparous‚ and viviparous. Know which

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

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

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
