Flashcards in circulatory worksheet Deck (36):
1

Small arteries that deliver blood to capillaries

Arterioles

2

The largest artery in the human body

Aorta

3

Layer of simple squamous epithelium lining all blood vessels

Endothellium

4

Cerebral circulation is the route for what

Blood to Brain

5

Capillaries with no gaps between endothelial cells
Present in nervous and muscle tissue

Continuous Capillaries

6

Middle layer of blood vessel walls, consisting of smooth muscle cells and elastic and collagen fibers

Tunica Media

7

Largest diameter arteries; often called conducting arteries

Elastic Arteries

8

Deposittion of a fat-like substance containing cholesterol in walls of arteries to form plaques

Atherosclerosis

9

Degenerative changes in arteries that make them less elastic

Arteriosclerosis

10

Blood passes from right ventricle directly into this vessel

Pulmonary Valve

11

Portion of the aorta that gives rise to the right and left coronary arteries

Ascending Aorta

12

Longest part of the aorta, running from the aortic arch to the common iliac arteries

Descending Aorta

13

Vein that returns blood from the head, neck, thorax, and upper limbs to the heart

Superior Vena Cava

14

______________is a bulge in a weakened blood vessel wall

Aneurysm

15

Vessels with the lowest resistance

Veins

16

Major means by which nutrients and waste products are exchanged across capillary surfaces

Diffusion

17

Given the following vessels:
aorta
inferior vena cava
pulmonary arteries
pulmonary veins

Which vessels carry oxygen-rich blood
(Pick two)

Aorta
Pulmonary Veins

18

Which artery is most commonly used to take the pulse near the wrist
basilar
brachial
cephalic
radial
ulnar

Radial

19

Facts about Pulse Pressure

The difference between systolic and diastolic pressure.

Increases when stroke volume increases.

Increases as vascular compliance decreases

20

Facts about veins

Increase their volume because of their large compliance

21

A sudden release of epinephrine from the adrenal medulla

Increases heart rate
Increases stroke volume
Causes vasoconstriction in visceral blood vessels

22

The outer layer of the arteries is the:

Tunica Adventitia
(also called Tunica Externa)

23

The ability of the arteries to withstand a sudden large increase in pressure is accomplished by the:

Elasticity of the smooth muscles

24

The major structural difference between arteries and veins is that in the veins, the:

Walls are thinner, Valves are present

25

The contraction of skeletal muscle:

Assist in venous return

26

Swollen Veins

Varicose Veins

27

Bleeding in blood vessels in brain

Brain Hemorrhage

28

Varicose veins in the walls of the recturm

Hemorrhoids

29

Bluish discoloration of the skin

Cyanosis

30

Blood in veins is kept flowing in one direction by the presence of

Valves

31

The maximum pressure in the artery, occurring during ventricular contraction is:

Systolic Pressure

32

Blood pressure is highest in the:

Artery

33

The Pulmonary Vein enters the:

Left Atrium

34

The abdominal aorta ends with the right and left______________arteries

Common Iliac

35

What is the pulse site used for CPR

Carotid Artery (in the neck)

36

Where do you take the most ACCURATE heart rate

Femoral Artery (groin)
