are tube-like structures capable of expanding and contracting

Answer 2

Blood vessels

Question 3

Blood vessels are consist of three types:

Answer 3

capillaries, arteries, and veins.

Question 4

are microscopic blood vessels through which materials are exchanged between blood and tissue cells.

Answer 4

Capillaries

Question 5

These tiny hair-like vessels cover every organ and structure throughout the body.

Question 5

These tiny hair-like vessels cover every organ and structure throughout the body.

Answer 5

capillaries

Question 6

Every cell in the body must be able to make contact with a [?] to receive oxygen and nutrients and rid itself of waste products.

Answer 6

capillary

Question 7

carry blood away from the heart.

Answer 7

Arteries

Question 8

Arteries carry oxygenated blood (except for the [?]).

Answer 8

pulmonary artery

Question 9

They have thick elastic walls that expand and contract.

Answer 9

Arteries

Question 10

Arteries branch off into smaller arteries called

Answer 10

arterioles

Question 11

can be felt to have a “pulse” when a wave of blood is pushed through.

Answer 11

Arteries

Question 12

The [?] (the hollow passageway) of the artery is narrower than the vein.

Answer 12

lumen

Question 13

transport blood towards the heart.

Answer 13

Veins

Question 14

Veins carry deoxygenated blood (except for the [?] veins).

Answer 14

pulmonary

Question 15

They have thinner walls and area not as elastic.

Answer 15

Veins

Question 16

Large veins are made up of smaller veins called [?] that join together.

Answer 16

venules

Question 17

They also have small valves which prevent the backflow of blood, unlike in arteries where due to pressure backflow does not normally occur.

Answer 17

Veins

Question 18

The walls of the blood vessels have three
layers:

Answer 18

1. Tunica intima
2. Tunica media
3. Tunica externa

Question 19

› Innermost layer (towards the lumen)

Answer 19

Tunica intima

Question 20

› Comprised of a single layer of endothelial cells

Answer 20

Tunica intima

Question 21

› Middle layer

Answer 21

Tunica media

Question 22

› Comprised of smooth muscle cells, elastic and connective tissue

Answer 22

Tunica media

Question 23

› The layer is much thicker in arteries, and veins have fewer elastic fibers

Answer 23

Tunica media

Question 24

› Outermost layer

Answer 24

Tunica externa

Question 25

› Also known as the tunica adventitia

Answer 25

Tunica externa

Question 26

› composed entirely of connective fibers and surrounded by an external elastic lamina which functions to anchor vessels with

Answer 26

Tunica externa

Question 27

The veins of the arm may be divided into two groups:

Answer 27

deep veins and superficial veins

Question 28

accompany arteries within the fascial sleeve

Answer 28

deep veins

Question 29

lie for most of their course outside the fascial sleeve

Answer 29

superficial veins

Question 30

Deep veins, except for the axillary veins, are arranged in pairs, one on either side of the various arteries. The axillary vein, which is a direct continuation of the basilic vein, crosses the axilla and becomes the subclavian vein at the outer border of the first rib. Its branches correspond to those of the axillary artery, except for the thoracoacromial, which joins the cephalic vein. The axillary vein receives the brachial veins in the lower portion of the axilla and the cephalic vein in the upper portion of the axilla. These deep veins will not be of significance in venipuncture. The superficial veins of the upper limb are the veins selected for most elective venipuncture
