Cardiovascular Anatomy
This component of the blood consists of water, proteins, nutrients, hormones, etc.
What is plasma?
These "air like sacs" are the site of gas exchange in the lungs.
What are the alveoli?
This reflex is responsible for blood pressure homeostasis.
What is the baroreflex?
These receptors detect changes in arterial pH.
What are the chemoreceptors?
The effect of aerobic training on resting heart rate.
What is lower?
These arteries supply oxygenated blood to the heart itself.
What are the coronary arteries?
These principal muscles during inspiration elevate the rib cage.
What are the external intercostals?
The part of the brain is responsible for feed forward responses that activate the autonomic nervous system
What is central command?
This law describes the inverse relationship between volume and pressure at constant temperature.
What is Boyle's Law?
A condition in which the body has more volume of a liquid (i.e., plasma)
What is hypervolemia?
These sensory nerves detect changes in blood pressure.
What are the baroreceptors?
During quiet breathing, exhalation is facilitated by this
What is recoil [of principal muscle groups]?
This response is due to afferent feedback from metabo and mechanoreceptors in the active skeletal muscle.
What is the exercise pressor response?
What is hemoglobin?
This type of hypertrophy in the heart is associated with an increase in sarcomeres in series.
What is eccentric hypertrophy?
Cardiac cells are connected by these structures
What are desmosomes/intercalated discs?
These muscles pull the rib cage down and in during forced breathing.
What are the internal intercostals?
This refers to the blunted vasoconstrictor response in the active skeletal muscle.
What is functional sympatholysis?
The effect that results in the oxy-hemoglobin dissociation curve shifting to the right.
What is the Bohr effect?
The equation that determines maximal aerobic capacity (VO2 max).
What is the Fick Equation?
These autonomic nerves largely innervate the arteries
What are sympathetic nerve fibers?
This motor nerve innervates the diaphragm.
What is the phrenic nerve?
This mechanism describes the volume loading effect of increased venous return.
What is Frank Starling Mechanism?
The change in arterial and venous oxygen content due to skeletal muscle extraction.
What is the arterial venous oxygen difference (AVO2)?
The limiting factor in endurance performance.
