100
It is the approximate size of your heart.
What is the size of your fist?
100
It is what you call the visceral layer of the serous pericardium.
What is the epicardium?
100
It is the double-walled sac that curround the heart.
What is the pericarduim?
100
These are two vessels that return blood to the heart.
What are the superior and inferior venae cavae and the right and left pulmonary veins?
100
These are the discharging chambers of the heart.
What are the ventricles?
200
It is the dome shaped muscle your heart is located above.
What is the diaphragm?
200
It is the endothelial layer of the inner myocardial surface.
What is the endocardium?
200
It is what separates the parietal and visceral layers of the heart.
What is the fluid-filled pericardial cavity?
200
These are two vessel that convey blood away from the heart.
What are the pulmonary trunk (which split into the right and left pulmonary arteries) and the ascending aorta (which has three branches, brachiocephalic, left common carotid, and subclavian arteries)?
200
These are the receiving chambers of the heart.
What are the atria?
300
It is what your heart is anterior to.
What is your vertebral column?
300
It is the cardiac muscle layer forming the bulk of the heart.
What is the myocardium?
300
They are two functions of the pericardium.
What are protects and anchors the heart, prevents overfilling of the heart with blood, and provides a relatively friction-free environment?
300
These arteries supply the external heart with blood.
What are the right and left coronary, marginal, circumflex, and anterior interventricular arteries?
300
This circulation is the functional blood supply to the heart muscle
What is the coronary circulation?
400
It is what your heart is posterior to.
What is the sternum?
400
It is what the fibrous skeleton of the heart is comprised of.
What are crisscrossing, interlacing layers of connective tissue?
400
They are the two layers of the serous pericardium.
What are the parietal layer and visceral layer?
400
These veins drain the exterior heart.
What are the small cardiac, anterior cardiac, and great cardiac veins?
400
It is the function of collateral routes.
What is to ensure blood delivery to the heart when major vessels are occluded?
500
It is the location of your heart according to your midline.
What is left of the midline?
500
It is the type of tissue the heart wall is made of.
What is cardiac muscle tissue?
500
It is where the fibrous pericardium is in relation to the serous pericardium.
What is superficial?
500
They are the valves that prevent backflow into the atria when the ventricles contract.
What are the AV valves?
500
It is the function of heart valves.
What is to ensure unidirectional blood flow through the heart?
