The smallest blood vessels are the
arteries
arterioles
capillaries
veins
The correct blood flow through the heart is:
Body - RA - RV - lungs - LA - LV - body
Body - LA - LV - lungs - RA - RV - body
Body - RV - RA - lungs - LV - LA - body
Body - LV - LA - lungs - RV - RA - body
The right atrium
delivers deoxygenated blood to the lungs
delivers oxygenated blood to the body
receives deoxygenated blood from the body
receives oxygenated blood from the lungs
Blood from the LEFT ventricle goes to the
aorta
left atrium
right atrium
left ventricle
De-oxygenated blood is first received in the
left atrium
left ventricle
right atrium
right ventricle
The layer of the walls of arteries that helps maintain diastolic blood pressure is made of:
fibrous connective tissue and elastic connective tissue
smooth muscle and fibrous connective tissue
smooth muscle and elastic connective tissue
fibrous connective tissue and simple squamous epithelium
Backflow of blood within veins is prevented by:
Smooth muscle
Valves
Precapillary sphincters
The middle layer
In capillaries, O2 and CO2 are exchanged between the blood and tissue fluid by the process of:
Osmosis
Filtration
Active Transport
Diffusion
A systematic blood pressure reading always consists of two numbers, which are called:
systemic/systolic
systolic/diastolic
diastolic/systolic
diastolic/systemic

liver/heart
liver/brain
heart/liver
Following a large loss of blood, as in severe hemorrhage, blood pressure will?
Increase
Decrease
Remain the same
Increase, then decrease
Epinephrine increases blood pressure because it:
