Why are pig’s heart used to study the anatomy of human heart?
ANSWER: because they are very similar in structure, size and function to human hearts. These similarities, combined with the fact that they are much more readily available than human hearts, make them an ideal choice for research and study.
2. How can you say which side of the heart is the ventral surface?
ANSWER: There is a groove on the ventral side of the heart separating the left and right ventricle (where the sternum would be but on the outside). The left ventricle is the larger one.
3. How many chambers are found in the heart?
ANSWER: there are four chambers in human heart; two atriums and two ventricles
ATRIUMS- is a portion of the blood collection chamber of the heart. It is also sometimes called the auricle.
Ventricles- is one of two large chambers that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs.
4. Which chambers are the pumping chambers of the heart?
ANSWER: the pumping chambers are the lower two chambers, the ventricles. The right ventricle, pumps blood to the lungs, and the left ventricle pumps blood to the body through the aorta.
5. Which chambers are the receiving chambers of the heart?
ANSWER: there are two chambers on the top, the atria. The right atrium takes venous blood from the body, and the left atrium collects blood coming from the lungs where it has been oxygenated.
6. How will you compare the walls of the atria with the walls of the ventricles? Why are they different?
