BYU Cell 220 lesson 17: Blood vessels || 100% Accurate Answers.
What direction do arteries transport? What oxygen level do they carry and to what circuit?
correct answers -transports blood away from heart
-oxygen richin systematic circuit
-oxygen poor in pilmonary circuit ans umbikicak artery
What direction do veins transport and what oxygen level and circuit? correct answers -transports
towards heart
-oxygen poor in systematic
-oxygen rich in pulmonary bc bringing blood to heart and lungs
Where are capillary functions located? correct answers -located at gas and nutrient exchanges
between blood and tissues
What are the 3 vessel tunics and the parts inside them? What is the hole called? correct answers -
hole: lumen
1-Tunica Intima
-endothelium
- basement membrane
- internal elastic membrane
2- Tunica Media
-smooth muscle
-external elastic membrane
3- Tunica Externa
, -Vasa vasorum
What epithelial tissue is tunica íntima? correct answers Made of simple squamous epithelium
How is tunica medial arranged and where is it located? correct answers -arrangement: circularly
arranged smooth muscle fibers
-location: vasodilation and vasoconstriction
What is túnica externa made of? correct answers Collagen, elastic fibers, and contains vasa
vasorum
What are the walls, lumen and thickest tunic layer of arteries, capillaries, and veins? correct
answers Walls
- artery: thick
- vein: thin
Lumen
-artery: small
-vein: large
— capillary: very small
Tunica
-artery: media
-vein: externa
-cap: intima
Where do the blood vessels travel throughout body? correct answers heart-> elastic arteries->
muscular arteries-> medium veins-> large veins-> heart
