Sheep Heart Lab Report Essay
Aim:
To examine and dissect a sheep’s heart, to observe it’s structure as a two-part pump and it’s features.
Hypothesis :
That the left side of the heart will be bigger because the left side of the heart pumps blood around the whole body.
Apparatus:
Gloves
Dissection Board
Sheep’s heart
Scissors
Aluminium Foil
Newspaper
Method :
The heart was laid out with the septum coming diagonally from the upper right side to the lower left side.
The heart clambers were observed, examined and recorded.
The ventricles were pressed and pitched. Right side softer than left side.
The right ventricle was cut open parallel from the septum.
The left ventricle was cut open parallel from the septum.
The wall of the ventricle and valves were observed. …show more content…
The septum was diagonal from the upper right side to the lower left side. The left ventricle was much larger than the right ventricle. The left ventricle wall was nearly three times as hick as the wall of the right ventricle. The valves were ‘flaps’ attached by ‘strings’ to the heart muscle. When a finger was poked through the atria you could see it coming through the left ventricle. When a finger was poked through the pulmonary artery we saw the finger tip poked through right ventricle. Interpretation of Results:
The atria looked like ‘flaps’ because there was on blood flow because the heart had been removed.
The septum was diagonal not straight up and down because the left ventricle was larger in size than the right ventricle because it pumps blood to the whole body.
The right ventricle was a lot softer because it had less muscle than the left ventricle. As stated in the External Observations.
LV needs to exert more force.
The flaps are flaps to stop back flow of the blood and the valves need to be strong to last your whole life.
