9

Formed elements are produced from

stem cells in red bone marrow.

10

True/ False
Erythrocytes are modified for transport of oxygen.

~TRUE~

11

True/False
Most of the oxygen (from modified erythrocytes) is bound to the pigmented protein hemoglobin.

~TRUE~

12

There are ___ types of leukocytes.

5

13

The 5 different types of leukocytes can be distinguished on the basis of

card image

size, appearance of the nucleus, staining properties, presence & absence of visible cytoplasmic granuels.

14

White blood cells are active in

card image

phagocytosis (neutrophils & monocytes) and antibody formation (lymphocytes).

15

Blood serves to

transport oxygen & nutrients to body cells & to carry away carbon dioxide & metabolic wastes.

16

True/False
Blood carries away carbon dioxide & metabolic waste.

~TRUE~

17

Does blood transport oxygen & nutrients to body cells?

~YES~

18

Plasma contains approx. _a__% proteins, __b__, ___c__, _d___ & __e____, which are dissolved or suspended in water.

a. 10%
b. ions
c. nutrients
d. waste products
e. hormones

19

What happens to the proteins, ions, nutrients, waste products & hormones contained w/in plasma?

They are dissolved or suspended in water.

20

The heart is a __a__ _a__ that sends blood to the __b_ for oxygenation through the __c__ __c__ & to the remainder of the body through the __d_ _d__.

card image

a. double pump
b. lungs
c. pulmonary circuit
d. systemic circuit

21

Blood is received by the _a__ & is pumped in circulation by the __b__.

card image

a. atria
b. ventricles

22

True/False
Valves between the atria & ventricles include the tricuspid on the RIGHT SIDE of the heart & the bicuspid on the LEFT SIDE of the heart.

card image

~TRUE~

23

The valve on the LEFT SIDE of the heart is the___ valve?

BICUSPID

24

The valve on the RIGHT SIDE of the heart is the ___ valve?

TRICSUPID

25

What valves are found at the entrances of the pulmonary trunk & the aorta?

card image

SEMILUNAR VALVES

26

Blood is supplied to the heart muscle (myocardium) by what arteries?

card image

Coronary arteries

27

What is the myocardium?

card image

The heart muscle

28

Circulation of blood through the heart- visualization-

card image

Follow the blood flow path, while looking at the picture to get a better understanding of the pathway our blood travels through our heart.
**Bicuspid valve is also called the mitral valve.

29

Blood drains from the ____a_____ directly into the ___b__ __b__ through the ___c__ __c__.

a. myocardium
b. right atrium
c. coronary sinus

30

The hearts intrinsic beat is initiated by the __a__ _a__ and transmitted along the conduction system through the __b____.

a. Sinoatrial node
b. Myocardium

31

The intrinsic beat intiated by the sinoatrial node along the conduction system through the mycardium -is a wave of electrical activity & is what is measured on a

card image

ECG- Electrocardiogram

32

The cardiac cycle is the period from the

end of one ventricular contraction to the end of the next ventricular contraction.

33

True/False
The contraction phase of the cycles is __a__; the relaxation phase is __b__.

a. systole
b. diastole

34

The contraction phase of the cardiac cycle is called

systole

35

The relaxation phase of the cardiac cycle is called

diastole

36

The vascular system contains

card image

arteries, veins & capillaries.

37

Arteries carry blood

AWAY from the heart

38

Veins carry blood

TOWARD the heart

39

Capillaries is where

exchange takes place between blood & cells of the body.

40

True/False
Capillaries are microscopic vessels.

~TRUE~

41

As arteries get farther away from the heart they

become thinner & thinner

42

The smallest arteries are called

arterioles

43

True/ False
The veins parallel the arteries and usually have the same names.

~TRUE~

44

The ___a_________________ are the _b__ _b__ that empty into the __c__ __c__ of the heart.

card image

a. Superior & Inferior venae cavae
b. large veins
c. right atrium

45

True/ False
The walls of the arteries are thick & elastic, because they carry blood under high pressure.

~TRUE~

46

Vasoconstriction & Vasodilation result from

Contraction & relaxation of smooth muscle in the arterial walls.

47

Vasocontriction is ______ of the smooth muscle in the artery wall.

contraction

48

Vasodilation is ____ of smooth muscle in the artery wall.

relaxation

49

True/False
The contraction & relaxation influence blood pressure & blood distribution to the tissues.

~TRUE~

50

Vein walls are ___a___ & less ___b___ than those of the arteries, because they carry blood under lower pressure.

a. thinner
b. elastic

51

True/False
Arteries are thicker & more elastic than veins because they carry blood under high pressure.

~True~

52

Mechanisms that help draw venous blood back to the heart include:

a. pressure of the skeletal muscles on the veins
b. expansions of the chest in breathing
c. valves in the veins of the legs that keep blood moving in a forward direction.

53
