Reduction in diameter of arterioles due to the contraction of smooth muscles
What is vasoconstriction?
100
These receptor reflexes respond to changes in blood pressure
What are baroreceptor reflexes?
100
Released at the neurohypophysis, this hormone results in peripheral vasoconstriction and elevates blood pressure
What is Antidiuretic Hormone?
100
When chemoreceptors in the carotid bodies or aortic bodies detect either a rise in the carbon dioxide content or a fall in the pH of the arterial blood, this occurs.
What is the cardioinhibitory center is inhibited?
200
An example of a local vasoconstrictor
What is prostaglandin or thromboxane?
200
Increase in diameter of arterioles due to the relaxation of smooth muscles
What is vasodilation?
200
These receptor reflexes monitor changes in the chemical composition of arterial blood
What are chemoreceptor reflexes?
200
This hormone is released in response to a fall in renal blood pressure.
What is Angiotensin II?
300
An increase in this gas helps dilate vessels
What is carbon dioxide?
300
The neurotransmitter responsible for vasocontriction
What is norepinephrine?
300
The receptors that monitor blood pressure at the end of the systemic circuit
What are atrial baroreceptors?
300
This hormone stimulates the production and maturation of the red blood cells.
What is erythropoietin?
400
An increase in this gas helps dilate vessels
What is lactic acid?
400
The chemical compound responsible for vasodilation
What is nitric oxide?
400
Responds to the stretching of the wall of the right atrium
What is atrial reflex?
400
This hormone is produced by cardiac muscle cells in the wall of the right atrium in response to excessive stretching diastole.
What is Natriuretic Peptides?
500
In order for vasodilation to occur, temperature needs to do this
What is increase?
500
Center responsible for cardiac output and peripheral resistance
What is medulla oblongota?
500
The chemoreceptors are located in these locations
What are carotid bodies and aortic bodies?
500
A blockage ADH, aldosterone, epinephrine and norepinephrine decreases this
