QUESTIONS AND CORRECT ANSWERS
⩥ Beta Blockers (book). Answer: 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). Answer: 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. Answer: 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). Answer: pumps blood through the lungs
, ⩥ Left Heart (book). Answer: sends blood throughout the systemic
circulation, which supplies all of the body except the lungs.
⩥ Arteries (hint A for away) (Book). Answer: 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). Answer: 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). Answer: carry blood from capillaries
back to the heart.
⩥ Lymph (Book). Answer: is returned to the cardiovascular system by
vessels of the lymphatic system.
⩥ Blood flow through the heart chambers/valves (Book). Answer: 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
