|
The cardiovascular system |
A closed system of the heart and blood vessels; it’s function is to deliver oxygen and nutrients and to remove carbon dioxide and other waste products |
|
|
The heart |
Located in the thorax between the lungs; it’s about the size of your fist; it’s also pumps bloodb |
|
|
Pericardium |
A double walled sac |
|
|
Fibrous pericardium |
The loosely fitting superficial part of this sac is called; it helps protect the heart and anchors it to surrounding structures |
|
|
Serious pericardium |
Is deep to the fibrous pericardium and is composed of 2 layers (visceral and parietal) |
|
|
Visceral pericardium layer |
Next to the heart; also known as epicardium |
|
|
Parietal pericardium layer |
Is the outside layer that lines the inner surface of fibrous pericardium |
|
|
Serious fluid |
The space between the pericardium is called this |
|
|
The heart wall |
3 layers (epicardium, myocardium, and endocardium) |
|
|
Epicardium |
Outside layer; it’s also called the visceral pericardium; mostly connective tissue |
|
|
Myocardium |
Middle layer; mostly cardiac muscle |
|
|
Endocardium |
The inner layer endothelium |
|
|
Heart chambers |
The right and left side; Syria and ventricles |
|
|
Atria |
Receiving chambers (right and left side) |
|
|
Ventricles |
Discharging chambers (right and left side) |
|
|
Inter-ventricular Septa |
Separates the two ventricles and the two atrias |
|
|
Valves |
Allow blood to flow in only one direction to prevent backflow |
|
|
Valves |
Allow blood to flow in only one direction to prevent backflow |
|
|
Four valves |
Atrioventricular (tricuspid and bicuspid); semilunar (pulmonary and aortic) |

|
|
Aortic valve |
Is attached to the aorta and goes from heart to aorta |
|
|
Av valves |
Are anchored in place by the chordae tendineae (heart strings); they open during heart relaxation and are closed during ventricular contraction |

Systemic circulation |
Blood flows from the left side of the heart through the body tissues and back to the right side of the heart |
|
|
Pulmonary circulation |
Blood flows from the right side of the heat to the lungs and back to the left side of the heart |
|
|
Arteries |
Aorta (leaves the left ventricle) and pulmonary no oxygenveinsc (leaves the right ventricle) |
|
|
Veins |
Superior and inferior venae cavae (enter the right atrium) and pulmonary four oxygens (enter left atrium) |
