Anatomy- Cardiovascular System review

The heart is enclosed by this double layered sac

• serotonin

• pericardium

• cartilage

• synovial joint

The function of the cardiovascular system is

• to create hormones that are used to create memories

• to form a strong structure

• to contract and move the skeleton

• to supply oxygen and nutrients to tissues and remove waste

The part of the cardiovascular system that exchanges O2 and CO2 is the

• systemic circuit

• pulmonary circuit

• nervous circuit

• tissue circuit

Select the three layers of the heart (choose 3 answers)

• endocardium

• myocardium

• supracardium

• Epicardium

The function of the ventricles is to (choose two)

• receives blood from the lungs

• pushes blood into the pulmonary artery, then the lungs

• receives blood from vena cava

• pushes blood into the aorta

Heart valves prevent what?

• backflow

• heart beats

• fibrillation

• heart attacks

The AV valves (bicuspid and tricuspid valves) and Semilunar valves (pulmonary and aortic valves) have this relation:

• opposite

• identical

• they open and close together

• they are made of chordae tendinae

What valve does blood pass through between the left atrium to the left ventricle?

• tricuspid

• aortic

• pulmonary

• bicuspid

When blood leaves the lungs it travels into the left atrium via the:

• vena cava

• aorta

• coronary artery

• pulmonary veins

When the ventricles contract, pressure inside the ventricles increases sharply causing these valves to close to prevent backflow into the atria.

• Pulmonary bicuspid

• Chordae tendinae

• Semilunar valves (aortic and pulmonary)

• AV valves (tricuspid and bicuspid)
