This hormone is responsible for driving glucose into the cell
What is insulin?
What is fat?
An issue with this part of the cardiac conduction system would prevent electrical signals from traveling from the atria to the ventricles!
What is the Bundle of His?
What is parasympathetic withdrawal (removal)?
Gas exchange between the air and alveoli occur at this structure
What is the respiratory membrane?
This hormone is produced by the adrenal cortex
What is Cortisol?
Insulin decreases during exercise to regulate this molecule
What is glucose?
Ventricular depolarization is represented by this part of an EKG signal.
What is the QRS complex?
During exercise, most of your blood goes here.
What is muscle or active muscles?
For air to enter the lungs, the ribcage must do this.
What is expand?
Thyroid Hormone's primary function is this.
Regulate Metabolism
During exercise, concentrations of this hormone go up, then back down.
What is cortisol?
Vasoconstriction and vasodilation are regulated by this vascular structure!
What are arterioles?
SV plateaus during exercise due to decreased ventricular filling time and this.
What is (maxed out) contractility?
What is bicarbonate?
This hormone(s) increases the contractility of the heart and blood pressure!
What are the catecholamines (epinephrine and norepinephrine)
Depletion of this substrate increases with exercise intensity.
What is glycogen?
This relationship posits that preload is directly related to the stretching of the ventricles during diastole.
What is the Frank-Starling mechanism/law?
This measure of extraction increases with exercise intensity
What is a-vO2 Difference?
The Ventilatory Breakpoint is the point at which ventilation exceeds oxygen consumption, primarily driven by this metabolic byproduct.
What is H+?
These hormones increase fat mobilization!
What are glucagon, growth hormone, catecholamines, and cortisol?
Concentrations of sympathetic hormones begin to increase at this intensity level!
40-56% VO2 Max
This is the Cardiac Output (Q) of an individual with a Stroke Volume (SV) of 0.05L and a Heart Rate (HR) of 140BPM.
What is 7 (L/min)?
What is VO2 = 0.112?
A right shift in the oxyhemoglobin curve is caused by this.
What is increasing body temperature and decreasing pH (H+)?
