Circulatory system
What is the primary function of the circulatory system?
What are the components of the vascular system?
Pg 93
• The primary function of the circulatory system is to nourish the visceral with nutrients and oxygen
• The components of the vascular circuit include the lungs (pulmonary), the peripheral vessels (mainly iliac vessels), the visceral organs (digestive and urinary system) and the cephalic
Coronary Artery Disease
Description of CAD?
Pg 441
CAD
Pg 441
Coronary artery disease: A condition involving the arteries that supply the myocardium, in which the arteries become narrowed due to atherosclerotic deposits over time, causing temporary cardiac ischemia and eventually heart attack
Etiology of CAD
Difference btn atheroma vs. thrombus?
Pg 80
Etiology of CAD
Atheroma- mass of fibro-fatty material, cells and lipids
Pg 80
Thrombus- A blood clot attached to the interior wall of the blood vessel, often causing vascular obstruction
Etiology of CAD
A combination of the endothelial damage and the atheroma is called a ______________

What measures are initiated to reverse a cardiac arrest?
Pg 79
Cardiac arrest
What measures are initiated to reverse a cardiac arrest?
CPR must be instituted within 4 to 6 minutes of cardiac arrest by a trained, advanced life-support personnel. Cardiac drugs including adrenaline, dobutamine and antiarrhythmic drugs must be administered.
In addition, therapeutic hypothermia can be tried

Hypertension
Pg 25
•What is the first indication of hypertension? Elevated blood pressure readings -- systolic reading greater than 140 mm Hg and diastolic reading greater than 90 mm Hg indicate hypertension
Hypertension
Discuss the treatment of hypertension
