Cardiovascular Physiology Flashcards
The relaxation state of the heart in between heart beats in which the atrial chambers fill with blood.
a. Diastole
b. Systole
a. Diastole
The contraction state of the heart during heart beats when the ventricles pump blood out to the body.
a. Diastole
b. Systole
b. Systole
Protein found in red blood cells that helps to transport oxygen to all tissues.
Hemoglobin
Specialized to allow for continuous contractions via an enhanced sarcoplasmic reticulum and calcium delivery system to allow it to manage rapid and non-stop neural impulses.
Myocardium
Large, muscular-walled vessels suited for transporting oxygenated blood away from the heart to bodily tissues.
Arteries
Smaller, thinner-walled arteries that serve as the connecting units to capillaries.
Arterioles
Smallest vessels with the thinnest walls which allow for oxygen and nutrient exchange as well as waste product removal from muscles, organs, and other tissues.
Capillaries
Serve too pump deoxygenated blood back to the heart and lungs via special valves.
Veins
Measure of force exerted by circulating blood against arterial walls; it is modulated in response to activity, nutrition, body size, and health status.
Blood Pressure
Attempting to move a heavy load while holding one’s breath; it is contraindicated for those with hypertension.
Valsalva maneuver
CLINICAL diagnosis of high blood pressure that has a negative impact on cardiovascular function and causes vascular damage over time.
Hypertension
Maximal intensity of work that a steady state condition can be maintained; lactate accumulation begins to exceed removal which indicates acidity in the tissue and blood.
Lactate threshold
Transport oxygenated blood away from the heart to bodily tissues?
a. vein
b. arteries
c. arterioles
d. venules
