Flashcards in Circulation Deck (44):
1

This is the largest artery in the body.

Aorta

2

These are the characteristics of dirty blood.

Low O2 and high CO2.

3

This pathway carries blood from the heart to the lungs and back.

Pulmonary Circulation

4

These are the 2 large veins that bring dirty blood to the heart.

Superior Vena Cava
Inferior Vena Cava

5

These structures prevent blood from back-flowing in the heart.

Valves

6

This is the gas exchange that happens in the body cells.

Capillaries drop off O2 and pick up cellular waste in the form of CO2.

7

This long pathway carries blood from the heart to the body and back.

Systemic circulation

8

Most arteries carry this type of blood.

Clean

9

This is the direction arteries carry blood.

AWAY from the heart

10

These are unusual ARTERIES because they carry dirty blood from the heart.

Pulmonary arteries

11

Most veins carry this type of blood.

Dirty

12

This is the direction veins carry blood.

TOWARD the heart

13

These are unusual VEINS because they carry clean blood to the heart.

Pulmonary veins

14

These blood cells carry large amounts of oxygen.

RBC's

15

This is the liquid component of blood.

Plasma

16

This spot in the heart receives nerve impulses and causes the 2 atria to contract.

Sinoatrial Node

17

This body system works with the circulatory system to recycle fluids back into circulation.

Lymphatic System

18

This is the % of plasma that is composed of water.

90%

19

This is the iron rich protein found in Red Blood cells that carries O2.

Hemoglobin

20

These are the smallest blood vessels in the body.

Capillaries

21

This is the gas exchange that happens in the lung cells.

Capillaries drop off waste CO2 and pick up O2.

22

This is the name of a tiny air sac in the lungs.

Alveoli

23

These heart chambers RECEIVE blood.

Atria

24

These heart chambers disperse blood.

Ventricles

25

This side of the heart controls pulmonary circulation.

Right

26

This is the wall between the 2 ventricles of the heart.

Septum

27

These things help you to avoid cardiovascular disease.

Exercise
Control Weight
Avoid excessive stress

28

This is the name of the valve found between the right atrium & right ventricle.

Tricuspid valve

29

This side of the heart controls systemic circulation.

Left

30

Clean blood travels through this valve when leaving the heart to go to the body.

Aortic valve

31

These are tiny veins.

Venules

32

These blood cells help fight infection.

White Blood Cells

33

This is the name of the valve between the left atrium and left ventricle.

Mitral Valve

34

These are fragments of broken cells that are used for clotting blood.

Platelets

35

The right ventricle squeezes blood through this valve.

Pulmonary valve

36

These are tiny arteries.

Arterioles

37

This spot in the heart receives an impulse and causes the 2 VENTRICLES to contract.

Atrioventricular Node

38

This is the location of the sinoatrial node.

Right atrium

39

This is the scientific name of red blood cells.

erythrocytes

40

This is normal human blood pressure.

120/80

40

Plasma makes up this % of blood

55%

41

Blood vessels are like the __________ of cities.

Roads

42

This short pathway is from the heart to the lungs and back.

Pulmonary circulation

43

These are the three functions of blood.

Regulate body temperature
Transport nutrients and waste
Fight infection
