Diaphragm and Internal Intercostals
Abdominals and Internal Intercostals
Abdominals and External Intercostals
Sympathetic autonomic regulation of the heart causes all of the following except_______.
Positive chronotropic effects
Vasodilation of coronary arteries
Vasoconstriction of the coronary arteries
Increased myocardial contractility
If a patient is 38 years young with a resting heart rate of 68 bpm, what is the individuals heart rate reserve (HRR)?
182 bpm
114 bpm
252 bpm
150 bpm
What period of the cardiac cycle represents the ventricles contracting and expelling blood into the aorta and pulmonary artery in the cardiac cycle?
mid to late ventricular diastole phase
Early (Isovolumetric contraction) ventricular systole phase
mid to late ventricular Systole phase
Early diastole
In a healthy heart, preload is directly proportional to____________.
Stroke volume
Heart rate
Blood pressure
Afterload
Which statement is true regarding cardiac output?
The higher the afterload, the more easily blood is ejected from a ventricle
SV is the percent of blood pumped out of a ventricle with each contraction
An inverse relationship exist between venous return and preload
Within limits increased venous return= a greater volume of blood ejected from the heart

20-40 bpm
40-60 bpm
100-120 bpm

Left ventricular wall thickening (decreased compliance)
Decreased vascular thickness (increased compliance)
Decreased HR and SV
Decreased cardiac output
