Completion Questions
1. septum
2. pacemaker
3. pulmonary arteries
4. vena cavae
5. aorta
Definition/Function questions
1. Valves prevent blood or lymph from flowing backward.
2. The septum divides the heart into right and
left sides separating
the oxygenated and deoxygenated
blood.
Short Answer Questions
1. The left ventricle has to be more muscular as
it pumps blood to the
entire body.
2. Oxygenated blood is higher in oxygen and lower
in carbon dioxide than deoxygenated blood.
