structure of the cardiovascular system Flashcards
what does the right side of the heart do
The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs.
what does the left side of the heart do
The left-hand side pumps oxygenated blood around the body.
what is the atria for
The atria (plural of atrium) are where the blood collects when it enters the heart.
what are the ventricles for
The ventricles pump the blood out of the heart to the lungs or around the body.
what is the aorta for
The aorta is the largest artery in the body. It carries oxygenated blood away from the left ventricle to the body.
what is the vena cava for
The vena cava is the largest vein in the body. It carries deoxygenated blood from the body back to the heart.
what is the pulmonary artery for
The pulmonary artery carries deoxygenated blood away from the right ventricle to the lungs.
what is the pulmonary vein for
The pulmonary vein returns oxygenated blood from the lungs to the heart.
how does the circulatory cycle go
mouth-lungs-left atrium-left ventricle-aorta-full body-right atrium-right ventricle-lungs-mouth
define heart rate
number of heart beats per minute.avg 60-100 bpm
define stroke volume
the amount of blood pumped out of a ventricle.avg 50-100ml
define cardiac output
heart rate x stroke volume
how do you figure out someones maximum heart rate
