Graded A+
Clinical implication for Beta blockers? (book)
Ans: Atrial fibrillation, chronic left heart failure or reduced ejection fraction
Beta Blockers (book)
Ans: reduce myocardial demand. By blocking beta receptors.
Myocardial contractility is a change in developed tension at a given resting fiber
length, which is simply the ability of the heart muscle to shorten. At the molecular
level, thin filaments of actin slide over thick filaments of myosin called the cross-
bridge cycle of muscle contraction. (video)
Ans: Calcium interacts with troponin C which causes tropomyosin to move thus
allowing actin and myosin to work together to cause contraction.
Explain the difference between cardiac hemodynamic measures Video Lecture:
Cardiac Output
Ans: Cardiac output is the amount of blood pushed from the left ventricle in 1
minute. It is calculated by multiplying the heart rate in beats per minute by the
stroke volume.
Right Heart (book)

Ans: pumps blood through the lungs
Left Heart (book)
Ans: sends blood throughout the systemic circulation, which supplies all of the
body except the lungs.
Arteries (hint A for away) (Book)
Ans: carry blood (away) from the heart to all parts of the body, where they
branch into arterioles and even smaller vessels until they become a fine
meshwork of capillaries.
Capillaries (Book)
Ans: allow the closest contact and exchange between the blood and the
interstitial space, or interstitium—the environment in which the cells live
Venules and the veins (Book)
Ans: carry blood from capillaries back to the heart.
Lymph (Book)
Ans: is returned to the cardiovascular system by vessels of the lymphatic system.
Blood flow through the heart chambers/valves (Book)
Ans: The right heart pumps de-oxygenated blood through to the right
atrium>through the tricuspid valve> right ventricle>pulmonary semilunar
valve>pulmonary artery>Lungs (now oxygenated blood)>Pulmonary veins>Left
Atrium>Bicuspid or Mitral valve>Left Ventricle>Aortic Semilunar Valve>Aorta
The coronary arteries provide blood to which part of the heart. (Book)
