all vertebrates have a primary systemic heart that pumps blood to a large blood
vessel termed an ________. (vertebrates)
Give this one a try later!
artery
,innermost lining of the heart, composed of connective tissue covered by a layer of
epithelial cells
Give this one a try later!
endocardium
how is angiogenesis controlled during wound healing?
Give this one a try later!
when new blood vessels are needed, the body secretes angiogenic
activator molecules that promote blood vessel growth
why can insect maintain a high metabolic rate although their circulatory system is very
much simple?
Give this one a try later!
this circulatory system does not play a major role in oxygen transport
they can move interstitial fluid through their pseudocoelom by bulk flow powered by
contractions of the muscles in their body walls

, round worms
which types of blood vessels and hearts allow blood to be circulating in some
invertebrates and early vertebrate embryos?
Give this one a try later!
pulsating or contractile blood vessels and tube-like hearts move blood by
peristalsis
how does blood circulate in earthworms (oligochaeta)?
Give this one a try later!
contain a series of blood vessels that connect the large dorsal and ventral
blood vessels that run the length of the animal. the dorsal vessel is
contractile, and moves blood toward the head using rhythmic waves of
peristaltic contraction. the blood then flows through 5 pairs of muscular
contractile tubes that pump blood from the dorsal to the ventral blood
vessel. small connecting blood vessels carry the blood from the tissues
back to the dorsal vessel.
the conus arteriosus, seen in amphibians, is also divided to form the base of 3 large
arteries.....which are they?
Give this one a try later!
1. pulmonary artery (leads to the lungs)
2. the right aorta
, 3. the left aorta
the __________ _________ of mammals, which leads from the heart to the lungs, carries
deoxygenated blood, while the pulmonary vein, which leads from the lungs to the
heart, carries _________________ blood. In contrast, the aorta carries oxygenated blood,
while the venae cava (the large veins leading from the body to the heart) carry
_______________ blood
Give this one a try later!
1. pulmonary artery
2. oxygenated
3. deoxygenated
how is angiogenesis controlled?
Give this one a try later!
by both activator and inhibitor molecules that influence the rate of growth
and division of vascular endothelial cells
-the most porous of all capillaries
-found only in very specialized organs such as the liver and bone marrow
Give this one a try later!
sinusoidal capillaries
