The Heart Dissection Lab

A  Sheep's Heart

A Cow's Heart

A Pig's Heart

A Sheep's Heart has four chambers like most mammals. Two of the chambers are right and left atrium and the other chambers are left and right ventricles. During this lab we dissected some animals hearts. Our group dissected a pig's heart.
We measured the measurments of the heart.
Right Atrium- 9cm
Right Ventricle- 8cm
Outer Wall- 5cm
Aorta- 4.5cm
Pulmonary Trunk- 5cm
Left Atrium- 7cm
Left Ventricle- 10cm

Reflection Questions:
- The blood vessel that has the thickest walls are the arteries because of the amount of blood it has to carry.
-After viewing the cardiac muscle prepared slide under the microscope the cardiac muscle was striated.
- The danger of having this atherosclerotic plaque on the coronary artery is that it will block the blood flow.
- The heart closed reasembles the pigs because of the simparity between them , but most of the hearts have similar structures.
- Many differences that I observed in the heart specimens are as obvious as sight but the smaller parts are different from each other but basically the same expect for the smaller details.
- Adaptive reasons for these reasons is that animals hearts are adapted to fit the lifestyle and have larger arteries to pump blood faster while the heart of a human is smaller and compacted to fix our size.

By doing this lab I learned about the structure of the heart in animals. I learned more about arteries and what all is found in the heart more in depth. I gained knowledge about a sheep's, cow's, and a pig's heart. I learned that the heart in these three types of animals all have a similar structure. It was fun measuring the things that are found in the heart of how big it was and how thick it was. A human's heart is very similar to that of a pig, sheep, and a cow in which that was neat to learn about and explore it.
