5 True/False Questions
Stroke volume (SV) → is the volume of blood pumped during each heartbeat (cardiac cycle), and it is equal to end-diastolic volume minus end-systolic volume.
Superior Vena Cava → The semilunar valves are pushed open, and blood flows from the ventricles into the pulmonary trunk and aorta.
Heart Transplant → is the number of times the heart beats (contracts) per minute.
Endocarditis → is an inflammation of the serous pericardium.
Voltage-gated K+ channels → Temporarily substitutes for a patient's heart and lungs. It oxygenates the blood, removes carbon dioxide, and pumps blood throughout the body.
