Practical report on the disection of a sheep heart.

Heart Dissection Practical Report.

Introduction

On the of July 2002, a sheeps heart was figured by dissection. The heart is a muscle in all mammalian bodies that is used to handle agate line and nutrients through with(predicate)out the body.

A sheeps heart was used in this prac because handle the human heart it has four chambers and is similar in size. Two of these chambers are receiving chambers called the leave and castigate atrium. The other two are pumping chambers called the right and left ventricle.

The reliability of the cycle of blood through the body depends on the sequence of contractions from the atrium and the ventricle. When ever the atriums contract it is called the systolic phase. And when ever the ventricles contract, it is called the diastolic phase. These sequences ensure the blood flow through the heart. These occur sensation after the other to create a heart beat.

The blood flow through the heart starts when the right atrium takes the blood that flows through the superior or inferior vena cava. The right atrium and then fills with blood and the pressure of the blood causes the tricuspid valve to open. The blood then travels through into the right ventricle where it pusses the blood into the pulmonary arteries. by and by this the blood is pumped into the lungs where it is oxygenated, the oxygenated blood travels through the left ventricle then pushes the blood through the aorta, which provides the body with blood.

Aims

The aims and goals of this procedure was to:

1.Dissect and examine a mammalian heart

2.Develop dissection skills

3.



An in-depth investigation into how the heart works.

Materials

Materials used in this dissection were:

1.Sheeps heart

2.Scalpel

3.Rubber gloves

4.Dissection tray

5.Paper

Procedure

The first step in the dissection is to put on the synthetic rubber gloves before...

Does a thorough crinkle of not only inform us about a sheep heart but of how the dissection was done. I dissected a frog, but my report wasnt this detailed. Good job overall, but you need to look at your grammar a superficial more closely, it could be improved.
