Blood Vessels

Question 1

3 types of blood vessels
2 sub-types

Answer 1

arteries, capillaries, veins
arterioles, venules

Question 2

layers of arteries

Answer 2

tunica intima (endothelium, internal elastic membrane)
tunica media (smooth muscle, external elastin lamina)
tunica externa (connective tissue)

Question 3

layers of veins

Answer 3

lumen (valve)
tunica intima (endothelium, internal elastic membrane)
tunica media (smooth muscle, external elastin lamina)
tunica externa (connective tissue)

Question 4

clean blood waist blood

Answer 4

arteries release clean blood and the veins are sending waist blood back to the heart to get refiltered into clean

Question 5

capillary layers

Answer 5

endothelial cells, basement membrane

Question 6

capillary structures

Answer 6

continuous- tight gap junctions (artery)
fenestrated- loose gap junctions (vein)
sinusoidal- most permeable (liver, bone marrow, spleen)

Question 7

How are superficial veins and deep veins connected?

Answer 7

through a perforator vein

Question 8

blood clots

Answer 8

a clot is formed by backup, and an embolus is a piece of a blood clot that broke off. if that embolus enters the heart and into the lungs leading it to arteries where they get continuously smaller, it can clog and lead to cardiac event or stroke

Question 9

lymphatic fluid

Answer 9

contaminated/unfiltered fluid
interstitial fluid- clean lymphatic fluid that travels in arterial circulation

Question 10

lymphatic system structures

Answer 10

capillary bed, lymphatic vessels, lymph nodes

Question 11

lymphatic system functions

Answer 11

-transports oxygen, food material, and hormones, and brings CO2, metabolic waste sent to heart for filtration
- lymphatic fluid floods interstitial space

Question 12

lacteals

Answer 12

only located in the small intestine
- lymphatic vessels wrapped around arioles and veins

Question 13

lymph nodes function

Answer 13

filter fluids

Question 14

lymphatic fluid from the right quadrant and 3/4th

Answer 14

• collected and enters the venous system through the right subclavian jugular junction
• 3/4th collected through the thoracic duct and enters through the left subclavian jugular junction

Question 14

lymphatic fluid from the right quadrant and 3/4th

Answer 14

• collected through right lymphatic duct and enters through the right subclavian jugular junction
• 3/4th collected through the thoracic duct and enters through the left subclavian jugular junction
