Ventricles
What is the difference in function between the right and left ventricles of the heart?
right ventricle receives deoxygenated blood from the right atrium and pumps it to the lungs for oxygenation. left ventricle, receives oxygenated blood from the left atrium and pumps it out through the aorta to the rest of the body.
What is the main job of the lungs?
bring oxygen into the body for cells and remove waste carbon dioxide.
What is the heart's main job?
Acts as a pump for the circulatory system, delivering oxygen and nutrients to tissues and removing carbon dioxide and waste.
What are arteries?
Carry blood away from the heart, carry oxygenated blood
What are capillaries?
tiny, thin-walled blood vessels that connect small arteries to small veins
What is the "interventricular septum"
The interventricular septum is a thick muscular wall that separates the right and left ventricles.

What is a "coronary artery"?
arteries that supply blood directly to the heart muscle itself
What are the three types of capillaries?
Continuous, fenestrated, and sinusoids.

What is the name of the muscle below the lungs that helps you breathe?
The diaphragm
What is the heart muscle called?
The myocardium.
What is a common cause of artery-related diseases?
