Cardiovascular System
- Circulates a continuous supply of oxygen and nutrients to all parts of the body.
- Carries these materials in the body’s circulation within a series of blood vessels, pushed along mainly by the movements of the heart.
Functions of Cardiovascular System
-Heart (Pump)
-Blood Vessels (Pipes)
-Blood (Fluid)
Exchange of materials
Superior Vena Cava
Largest upper vein that returns blood to the heart
Inferior Vena Cava
Lower vein that returns blood to the heart
Pulmonary Artery
Artery that flows blood away from the body and into the lungs
Left Atrium
From the lungs
Tricuspid Valve
Prevents backflow
Bicuspid Valve
Prevents backflow
Endocardium
Inner Wall
Myocardium
Middle Wall
Epicardium
Outer Wall

Blood Capillaries
Exchange of oxygen, CO2, nutrients and waste products at the cellular level
Pulmonary Circuit

Circulatory Circuit
Left to right
Cardiovascular Disease
Can reduce or stop blood flow to parts of the body, which can result in cell death
Cardiology
Study of the heart
Cardiologist
Specializes in the heart
Cardiovascular
The entire circulatory system
Angina Pectoris
- A type of chest pain, pressure or discomfort
- Heart is not receiving enough oxygen due to narrowed coronary artery
- Rest and medication (nitrates)
Angiospasm
angi/o: blood vessels
Spasm: sudden involuntary muscle contraction (vasospasm)
-Chest pain at rest
Arrhythmia
Irregular Pulse
Dysrhythmia
Irregular Pulse
Bradycardia
Brady: Slow
Cardi/o: Heart
-ia: Condition of
Cardiogenic
Origin: The heart
Cyanosis
