Study These Flashcards
A

Deoxygenated Blood

25
What vein carries oxygenated blood?
The Pulmonary Veins
26
The SA Node stands for...
Sinoatrial Node
27
The heart is a
Muscular organ that pumps blood through the body
28
Blood contains
CO², O², Nutrients, Hormones
29
Functions of blood
*Deliver O² & Nutrients to cells *Remove waste products (CO²) *Regulates body temperate *Transports hormones & immune cells *Protects against infection
30
Size of the heart
Roughly a clenched fist
31
Weight of the heart
10oz.
32
Location of the Heart
Superior to the Diaphragm, Posterior to the Sternum, Anterior to the Spinal Cord, Medial to the Lungs
33
The Pericardium is
a thin, fluid-filled sac that surrounds the heart; connected to major blood vessels (Aorta, Vena Cava)
34
The Epicardium is
the Innermost layer of the Pericardium
35
The Myocardium is
A thick, cardiac muscle
36
The Endocardium is
The innermost layer --> Smooth Lining
37
The Right Atrium recieves
Deoxygenated Blood from the Veins (Superior Vena Cava, Coronary Veins)
38
The Right Ventricle recieves
Deoxygenated Blood from the Right Atrium and pumps it to the Lungs (Via. Pulmonary Artery)
39
The Left Atrium recieves
Oxygenated blood from the Pulmonary Veins (Lungs) and pumps the blood to the Left Ventricle
40
The Left Ventricle recieves
Oxygenated Blood from the Left Atrium and pumps Blood into the Aorta.
41
The Strongest Chamber is
The Left Ventricle
42
Definition of Heart
A muscular organ that pumps blood through the body.
43
What are all the blood vessels?
Arteries, Arterioles, Capillaries, Veins, Venules
44
What is blood?
A fluid that contains oxygen, nutrients, & hormones.
45
What is 1?
Fibrous Pericardium
46
What is 2?
Parietal Pericardium
47
What is 3?
Epicardium / Visceral Pericardium
48
What is 4?
Endocardium
49
What is 5?
Myocardium
50
What is 6?
Pericardial Cavity
51
The Parietal cavity Contains...
Fluid
52
What is the Apex of the Heart?
The tip of the left ventricle (it also remains stationary throughout the entire cardiac cycle)
53
What happens if you have Bad Circulation?
Cells die, then tissues, then organs will fail. *The cardiovascular system is the MOST IMPORTANT, it begins life's functioning and will stop shortly after death.
54
Define Arterial Bleeding
- Spurts of bright, red blood - Each time heart beats ( continuous spurts of blood ) - Difficult to control, SERIOUS condition
55
Define Venous Bleeding
- Steady flow - Blood is dark red - Looks purplish--> oxygen poor blood
56
How much blood does someone have?
4-6L of blood (7-8% total bodyweight)
57
Erythrocyte meaning
Red Blood Cell
58
Luekocyte meaning
White Blood Cell
