Question 5

peripheral blood smear

Answer 5

white space = plasma, darker purple = lymphocyte, neutrophil has a dip/space in the darker purple/nucleus

Question 6

bone marrow

Answer 6

monocyte has a dipped (no space) nucleus, eosinophil is lighter purple in cell and then has dark purple nucleus (may have a lighter pink tint to it), basophil is just all dark purple

Question 7

artery versus vein histology

Answer 7

artery has a much thicker media (it goes externa, media, intima) - I believe intima is one cell line

Question 8

tissue type surrounding blood vessels

Answer 8

adipose connective tissue

Question 9

elastic artery

Answer 9

ex: aorta, these are the largest arteries and have elastic connective tissue in the tunica media (withstand pressure from the heart and recoil to maintain shape)

Question 10

muscular artery

Answer 10

ex: radial artery, have a thicker smooth muscle layer at the tunica media, feel firm and rubbery under palpation in cadaver

Question 11

arteriole

Answer 11

small, smallest arteries, with an incomplete or very small tunica media

Question 12

venule

Answer 12

really small, lots of white around, smallest veins receiving blood from capillaries

Question 13

large vein

Answer 13

vena cava, do not have valves and will be found closest to heart, looks to have a thicker darker media

Question 14

Answer 14

brachial vein, have venous valves periodically along the length which facilitate one-way blood flow back to the heart. include deep veins and superficial veins

Question 15

what connects veins to arteries

Answer 15

capillaries

Question 16

lymphatic system (lymph node)

Answer 16

layers: capsule is outer layer, cortex is middle/blue, medulla is in total middle
so cap, cort, med
