Q

FhisAortic valve

A

between the left ventricle and the aorta; largest artery in the body; closes when the left ventricle is finished contracting; allows blood to flow into the aorta, preventing blood from flowing back into the left ventricle

20
Q

Describe the pattern of blood flow through the heart

A

Deoxygenated blood flows: body → right atrium → right ventricle → lungs.
Oxygenated blood flows: lungs → left atrium → left ventricle → body.

21
Q

Aorta

A

Largest blood vessel in the body; transports oxygen rich blood from the heart to the rest of the body

22
Q

First step in Conductive Pathway

A

SA node in the right atrium creates an electrical signal that tells the atrial muscles to contract

23
Q
A
24
Q

Second step of Conductive transfer

A

Signal moves to the AV node (nerve cells between atria and ventricles) slows the signal down so atria can finish pumping blood in the ventricles.

25
Q

Third step of Conductive Pathway

A

AV node signal travels down Bundle of His

26
Q

Bundle of His

A

Nerve fibers in the septum that carry impulses; Center of the heart.

27
Q

Fourth Step

A

The bundle splits into two ( one for right one fore left) and carry the signal to the bottom of the heart

28
Q

Fifth Step

A

signal spreads through thin fibers called the purkinje fivers, making the ventricles pump blood out to the body.

29
Q

Three main kinds of blood cells

A

Erythrocytes, Leukocytes, and Thrombocytes.

30
Q

Erythrocytes

A

red blood cells; contain hemoglobin

31
Q

Hemoglobin

A

carries oxygen and carbon dioxide; gives blood its color

32
Q

Leukocytes

A

white blood cells; fight infection by engulfing and destroying germs and pathogens

33
Q

Thrombocytes

A

aka platelets; fragments of cells that lack nuclei and vary in shape and size; main function is to stop bleeding by clotting.

34
Q

Anemia*

A

Inadequate number of red blood cells, low hemoglobin levels or both.

35
Q

Hypoxia

A

lack of oxygen supply

36
Q

Hemorrhage

A

Can cause rapid blood loss; acute blood loss anemia

37
Q

Iron deficiency anemia

A

When there’s in inadequate amount of iron to form hemoglobin

38
Q

Aplastic Anemia

A

results from injury to the bone marrow; results in poor or no formation of blood cells

39
Q

Pernicious anemia

A

When the red blood cells are abnormally large in size,

40
Q

Sickle cell anemia

A

inherited disease; production of abnormally shaped red blood cells

41
Q

Atherosclerosis

A

Occurs when fatty plaques are deposited on the walls of the arteries, narrowing the arterial opening; reducing or eliminating blood flow

42
Q

Bypass surgey is used when…

A

arteries are completely blocked

43
Q

Phlebitis

A

inflammation of a vein

44
Q

Thrombus

A

blood clot

45
Q

Thrombophlebitis

A

when a thrombus forms in a vein deep within the muscle

46
Q

Congestive heart failure

A

occurs when the heart muscles do not beat adequately enough to supply blood needs to the body
