Circulatory Quiz Review



Pulmonary vs. Systematic:

Pulmonary:
blood takes up oxygen in lungs
deoxygenated blood
right side of the heart
walls are thinner

Systematic:
oxygenated blood
blood distrubuted to body
walls are thicker

Similarities:
carry blood to the tissues of whole body
both necessary to homeostasis

Arteries vs. Veins:

Arteries:
have a thicker wall because of larger middle area
have arteriole

Veins:
layer in diameter
have venule and valves
thinner wall
walls have less smooth muscle & connective tissue

Similarities:
walls have 3 layers
inner layer composed largely of endothelium with basement membrane that has elastic fibers
middle layers is smooth tissue
outer layer is connective tissue (collagen fibers)

Fetal Circulation:

Ductus Venosus: umbilical vein attaches to vena cava
Ductus Arteriosis: between pulmonary trunk and aorta, make sure blood doesnt go into fetus lungs
Foramenovale: allows blood into R.A and L.A
