LEARNING FROM LECTURES 225

Ask yourself: “If the information I wrote in my notes was an answer

to a test question, what would the questions be?” In general, you

should have three to four questions for each page of notes. If you can-

not think of questions for certain parts of your notes, you probably

do not understand the content or did not write enough information

rt. & left atria —collect blood from major veins and

empty it into ventricles

right & left ventricles—muscles whose contract. forces

blood to flow-through arteries to all parts of body

f

lungs.

If valves are damaged, the efficiency of the heart as a pump

is diminished.

ent. are weakened he

What are the different

chambers of the heart?

What are the functions of the

different chambers?

What happens if the valves in a

heart are damaged?

What happens if the ventricles in a

heart are damaged?

Heart —muscular pump that provides pressure to pump

blood throughout body

Four chambers

Atrioventricular valves—between atria and ventricles that

allow blood to flow from the atria to the ventricles, prevent

flow in opposite direction.

Semiliunar valves—valves in aorta and pulmonary artery

aorta —carries blood from the le t ventricle to body

pulmonary artery—carries blood from the right ven-

tricle to the

person may develop sympt. such as enlarged heart.

Diagnosed by abnormal sounds as blood passes through

them —heart murmurs.

If v by infection , lack of exercise, etc. t

Symptoms—chest pain , shortness of breath

pain caused by heart not getting suff. blood.

Portion o heart muscle not receiving blood will die n time

Summary question (for complete lecture):

How does the heart function?
