How many chambers does the heart have?

What are the 3 main types of blood vessels?
Arteries, veins, capillaries
What is a healthy blood pressure for a young adult?
120/80
Which side of the heart is filled with deoxygenated blood?
Right side
What is the role of capillaries in the circulatory system?
What is the other name of the condition "high blood pressure?"
Hypertension
Compare and contrast the structure of arteries and veins
Arteries are thicker, veins are thinner. Arteries have high pressure, veins have low pressure. Arteries do not have valves, veins have valves. Arteries usually carry oxygenated blood, veins usually carry deoxygenated blood.
What instrument is used to measure blood pressure?
Sphygmomanometer
What are four functions of the circulatory system?
Transport: carbon dioxide, wastes, nutrients, oxygen, immunity, heat regulation, etc.
Which arteries supply blood to the heart muscle itself?
Coronary arteries
The condition where cholesterol deposits form plaques within arteries, reducing their diameter and increasing blood pressure.
Atherosclerosis
Name the four valves in the heart.
2 atrioventricular valves (tricuspid and bicuspid/mitral) and 2 semilunar valves (aortic and pulmonary)
Which blood vessel has the highest pressure in the whole body?
Aorta
Define vasoconstriction, vasodilation, and describe their effects on blood pressure.
Vasoconstriction is the narrowing of blood vessels, increases BP. Vasodilation is the widening of blood vessels, decreases BP
