Joselyn Bodnar Heart lab dissection 3/2/15 The Human heart has many complicated processes. Dissecting a sheep’s heart can help to provide an active‚ firsthand learning experience that allows to illustrate what has been previously heard and read. The sheep heart and a human heart share the same function and purpose‚ which is to keep the body alive by continually circulating blood around the body. Like a human heart‚ a sheep’s heart contains two atria and two ventricles. These four chambers

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues‚ that is‚ they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells‚ the gelatin the support material for matrix‚ and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances‚ we can produce a material that is very hard like

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

Heart Dissection Sheep have a four-chambered heart‚ as do humans. By studying a sheep heart you can learn about your own heart at the same time. 1. Identify the right and left sides of the heart. Look closely and on one side you will see a diagonal line of blood vessels that divide the heart. The half that includes all of the apex of the heart is the left side. If you feel the heart‚ the left half will feel much firmer and more muscular than the right side. The left side of the heart has to

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

several colleagues undertook a test‚ involving rats‚ to attempt to explain drug tolerance. They injected rats with a small amount of ethanol every day for four days‚ before moving half of the rats to a new location and injecting them with a larger amount of ethanol. The rats that stayed in the same location remained relatively healthy‚ while nearly two-thirds of the rats in the new location died of alcohol poisoning. A similar experiment involving rats and morphine showed that the body can overcompensate

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

Background: As members of the class Amphibia‚ frogs may live some of their adult lives on land‚ but they must return to water to reproduce. Eggs are laid and fertilized in water. On the outside of the frog’s head are two external nares‚ or nostrils; two tympani‚ or eardrums; and two eyes‚ each of which has three lids. The third lid‚ called the nictitating membrane‚ is transparent. Inside the mouth are two internal nares‚ or openings into the nostrils; two vomerine teeth in the middle of the roof
