Hormones
During exercise, growth hormone does this to the release of free fatty acids.
what is increases?
The primary component of plasma.
What is water?
The accumulation of metabolic by-products in muscle leads to this.
What is vasodilation?
This is how prevalent deaths are during exercise.
What is rare?
The point at which ventilation increases disproportionately compared to oxygen consumption
What is the ventilatory threshold?
This is an example of upregulation.
These are three things that assist with venous return
What are the muscle pump, one way valves and respiratory valves?
These are three of the four factors we discussed that influence heart rate variability.
What are body core temperature, parasympathetic nerve activity, sympathetic nerve activity or respiratory rate?
This theory explains the rapid change in heart rate, cardiac output and blood pressure during exercise.
What is central command?
The majority of carbon dioxide is transported as this molecule.
What is bicarbonate?
The hormone that increases water reabsorption at the kidneys to help reduce water loss and dehydration.
What is ADH?
This is the Fick equation.
where Q = HR x SV?
A decrease in cardiac output after resistance exercise can lead to this happening to your blood pressure.
What is hypotension?
What is excess CO2 needs to be "blown off" or removed?
The portion of hemoglobin that CO2 binds to.
What is the globular protein (globin)?
The parasympathetic nervous system carries impulses to the SA and AV nodes via this hormone.
This the term for the blunting or overriding of sympathetic vasoconstriction in exercising muscle.
What is sympatholysis?
The typical resting and exercising cardiac output in L/min in a trained individual.
What is 5L/min and 40L/min?
Within the muscle cells, this transports oxygen.
What is myoglobin?
This posture improves ventilatory capacity during recovery from maximal exercise.
What is forward-leaning position?
This hormone is decreased from acute, vigorous exercise to reduce hunger.
What is ghrelin?
What is withdrawal of the parasympathetic system?
This is a physiological principle that explains how the heart responds to changes in venous return. Increases in venous return cause the heart's chambers to fill with more blood, which then causes the heart to stretch and contract more forcefully and pump more blood out to the rest of the body.
What is the Frank-Starling mechanism?
There are in the aortic arch and carotid arteries and are sensitive to changes in blood pressure.
What are baroreceptors?
The dropping of partial pressure of oxygen at sea level from dry ambient air to the tissues and into the venous circulation
What is the oxygen cascade?
