Pig hearts are used for dissection for this reason.
Why is it similar in size and function to a human heart?
Another name for the bicuspid valve.
What is the mitral valve?
A blockage in the coronary artery can lead to this.
What is a heart attack?
_____ carries blood away from the heart, _____ carries blood toward the heart.
What are arteries and veins?
The difference between the right and left side of the heart.
Why is the right thinner and the left thicker?
The name of the first cut made in the pig heart dissection.
What is a frontal cut?
There are this many chambers in a mammalian heart.
What is four?
Function of the heart?
What is a muscular double pump with two functions: receiving oxygen-poor blood and oxygenated blood?
These chambers receive the blood as it comes back to the heart.
What are atria?
The medical name for "heart strings".
What is the chordae tendineae?
Cutting into the aorta during a dissection reveals semilunar valves shaped like this geometric form.
What are semi-circles or half-moons?
This wall of tissue divides the heart's right and left sides.
What is a septum?
The reason why backflow is harmful.
How does it forces the heart to work harder, making it less efficient at pumping blood? It can lead to heart failure.
These are the major vessels returning blood to the heart.
What are the superior and inferior vena cava and right & left pulmonary veins?
The pumping and receiving chambers of the heart.
What are the
pumping = ventricle
receicing = atria
This is the best way to prevent students from cutting through both sides of the heart.
What is a probe?
The reason why the inner walls of the ventricle have ridges and aren't smooth.
How does it increase the surface area, strengthen walls, and aid in pumping?
This happens if the chordae tendineae rupture.
What is sudden valve failure that causes backflow and can lead to fluid filling in the lungs?
The blood vessels are where the exchange of oxygen and nutrients occurs.
What are the capillaries?
This artery originates just behind the aortic semilunar valve cusps.
What are the coronary arteries?
This is a tough, outer tissue sometimes seen on the heart.
What is fibrous pericardium?
If there is damage to the left ventricle, it causes more severe consequences than damage to the right.
Why does it supply the entire systemic circulation?
Explain broken heart syndrome.
What is the temporary weakening of the heart that is typically triggered by emotional or physical stress?
Following the flow of the heart, name each structure in order.
What is the
Superior/inferior vena cava, right atrium, tricuspid valve, right ventricle, pulmonary semilunar valves, pulmonary artery, lungs, pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic semilunar valve, aorta?
Receives deoxygenated blood from the right atrium via the tricuspid valve, and pumps it into the pulmonary arteries via the pulmonary semilunar valve and pulmonary trunk.
What is the Right Ventricle?
