Animal Dissection: No Longer Cutting Edge American Politics 115-01 Dr. Griffith Chelsea Morrison April 24‚ 2012 The use of animals in science that results in harm or death has traditionally played an integral role in education. Many thousands of animals have been killed worldwide during attempts to teach practical skills or to demonstrate scientific principles which have‚ in many cases‚ been established for decades. Anatomy and experimental physiology started to be practiced around 300 B.C

The circulatory system consists of the heart‚ blood vessels‚ and blood. The heart has two receiving chambers‚ or atria‚

Cow’s eye dissection AIM ~ To locate and distinguish specific parts to an eye of a cow‚ in particular‚ its lens. OBSERVATIONS ~ Before actually beginning the dissection of the cow’s eye‚ we were about to sketch a fairly relative picture of our observing’s of the exterior body of the eye. The eye‚ having almost completely being sheltered in fat and muscle‚ was quite firm and only the cornea and optic nerve was identified. By further cutting down the fat‚ we were able to spot a rather tough pinkie

Dissection lab In the past 3 weeks we have been dissecting animals of all different sorts. We dissected a worm‚ crayfish‚ grasshopper‚ and a perch (fish). In my conclusion I will explain the diet‚ habitat‚ and how these relate to the structure of these animals. First I am going to be talking about the worm. The Earthworms have setae in groups around or under their body. The setae‚ paired in groups on each segment‚ can be moved in and out to grip the ground or the walls of a burrow. Worms travel

Aerobic Exercise on Heart Rate Introduction: Our bodies need to be in balance in order to function properly‚ and there are many ways the body maintains balance‚ or homeostasis. Homeostasis is the maintenance of nearly constant conditions in the internal environment. Our normal heart rate is an example of our body in homeostasis and any sort of change‚ or stimulus‚ can alter it. Exercise‚ adrenaline in the blood‚ and a low blood pH are all stimuli that increase the heart rate. Exercise‚ for example

Introduction: Heart Rate is defined as the amount of times a person’s heart beats in one minute. A resting heart rate is the person’s heart rate prior to any activity or exercise. As activity increases‚ the heart rate will increase in speed. An increased heart rate is essential as it replaces oxygen in the muscles that is used during said activity and gets rid of excess carbon dioxide through the blood stream. Blood pressure is the force of the blood pushing on the walls of the veins and arteries

Effect of Exercise on Heart Rate. Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Hypothesis: I predict that as I increase the intensity of the exercise I do‚ that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat

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
