coronary sinus
all tissues of the heart
venous valves: where
in limbs, both deep and superficial ones have them but more prevalent in deep
superficial veins are ____ and do not accompany____
larger, arteries
superficial veins return most of the blood to ____
the heart
superficial and deep veins ______ with each other extensively
anastomose
deep veins
brachiocephalic, subclavian, axillary, brachial, ulnar, and radial
superficial
cephalic, basilic, median antebrachial
_____, ____ ,_____, ______, all drain into the brachial vein
radial, ulnar, median cubital, basilic
cephalic veins drain into_____
axillary
ductus venosus
a way in fetal circulation to bypass the liver (attached to the placenta)
____ in the left atrium increases at birth, resulting in closure of the ______
pressure, foramen ovale
medial umbilical ligaments
remnants of the umbilical arteries
umbilical vein
collapses to form the ligamentum teres (round ligament)
postcapillary venules
TI: endothelium and basement membrane, no TM and sparse TE, pass blood into muscular venules, permit exchange of nutrients and wastes between blood and interstitial fluid and functionin white blood cell emigration
muscular venules
TI: endotheluim . and basement membrane, TM: one or two layers of circularly layers of smooth mjscle, sparse TE, pass blood into veins, reservoirs for accumulating large volumes of blood
veins
TI: endothelium and basement membrane, no internal elastic lamina, contains valves, lumen much larger than accompanying artery, TM: much thinner that in arteries, no external elastic lamins, TE: thickest of 3 layers, return blood to the heart facilitated by valves in veins in limbs
venous sinuses have..
a thin endothelial lining and no smooth muscle
capillaries
TI: endothelium and basement membrane, no TM or TE, permit exchange of nutrients and wastes between blood and interstitial fliud, distribute blood to postcapillary venules
3 different kinds of capillaries
continuous, fenestrated, sinusoids
blood flows through the capillary bed when sphincter is ____
relaxed
continuous capillaries
most common, small intercellular cleft, tight junctions to prevent leaking
fenestrated capillaries
found in kidney, small intestine, choroid plexus (brain capillary=CSF), endocrine glands, contain many pores
sinusoids
largest pores/leakiest of the 3, in liver, spleen, bone marrow, adrenal/pituitary glands
thoroughfare channel
a way to bypass the capillary bed if precapillary sphincters are contracted
subdivisions of the systemic circuit
coronary, cerebral, hepatic portal
