In this experiment, we obtained a fresh heart and dissected it to examine and

observe the different parts of the heart, as well as studying how they function and work

Problem: How can we study the heart through dissection?

The most basic function of the circulatory system is to move the blood. The

organ that provides the force to push the blood through the vessels is the heart. The

mammalian heart is composed of four chambers to which large blood vessels are

connected. The walls of these chambers are made of cardiac muscle tissue. It is the

contraction of these muscular walls in a synchronized manner that moves the blood

through this pump and its connected vessels. Valves are present in several locations,

where they function to maintain a indirectional flow of blood.

By doing this experiment, we will gain an understanding of the complexity of a

inspecting the valves. We will also learn about our own hearts, because besides the

pumps blood to the rest of the body, except for the lungs, thus creating a double beat.

the left atrium. The atria contracts, and causes the ventricles to fill with blood. This

3) Why is the mammalian heart often described as "two hearts that beat as one"?

Materials: mammalian heart, glass probe, dissecting pan, single-edged razor blade,

The blood must be able to flow from the atria and to the ventricles. The lag
