CORRECT!!
Clinical implication for Beta blockers? (book) - (Correct Answer)Atrial fibrillation, chronic left
heart failure or reduced ejection fraction
Beta Blockers (book) - (Correct 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) -
(Correct Answer)Calcium interacts with troponin C which causes tropomyosin to move thus
allowing actin and myosin to work心的坚强决定了我们的命运。当

Cardiac Output - (Correct 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) - (Correct Answer)pumps blood through the lungs
Left Heart (book) - (Correct Answer)sends blood throughout the systemic circulation, which
supplies all of the body except the lungs.
Arteries (hint A for away) (Book) - (Correct 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) - (Correct 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) - (Correct Answer)carry blood from capillaries back to the heart.
Lymph (Book) - (Correct Answer)is returned to the cardiovascular system by vessels of the
lymphatic system.
Blood flow through the heart chambers/valves (Book) - (Correct Answer)The right heart pumps

The coronary arteries provide blood to which part of the heart. (Book) - (Correct Answer)The
myocardium and other heart structures are supplied with oxygen and nutrients by the coronary

What are the two major coronary arteries? (Book) - (Correct Answer)The major coronary arteries
are the right coronary artery (RCA) and the left coronary artery (LCA)
The transmission of electrical impulses, termed cardiac action potentials move throughout the
myocardium. Analyze the process of action potentials. (Book) - (Correct Answer)As an electrical
impulse passes from cell to cell (fiber to fiber) in the myocardium, it stimulates an intracellular
process that results in fiber shortening—that is, muscular contraction or systole. Between action
potentials, the fibers relax and return to their resting length, causing diastole.
The various phases of the cardiac action potential are related
to changes in the permeability of the cell membrane to sodium,
potassium, chloride, and calcium(Book) - (Correct Answer)Threshold is the point at which the
cell membrane's selective permeability to these ions is temporarily disrupted, leading to
