Cardiovascular Drugs Flashcards
one of the primary function is the delivery of oxygen, nutrients , hormones, electrolytes, and other essential to cells.
Circulatory system
The circulatory system is composed of:
Heart & Blood vessels
It is the pump that moves blood through the arterial tree.
Heart
It is the transport blood under high pressure to tissues.
Arteries
are control valves that regulate local blood flow.
Arterioles
are the sites for exchange of fluid, oxygen, carbon dioxide, nutrients, hormones, and wastes.
Capillaries
The one who collect blood from the capillaries.
Venules
Transport blood back to the heart.in addition, veins serve as a major reservoir for blood.
Veins
amount of tension ( stretch) applied to a muscle before contraction = force of venous return.
Preload
a load against which a muscle exerts its force= arterial pressure that the left ventricle overcomes to eject blood.
Afterload
It is controlled by the ANS
Heart Rate
It is determined by myocardial contractility (force with which the ventricles contract), cardiac afterload,and cardiac preload.
Stroke Volume
defined as a persistent systolic pressure of greater than 140 mmHg and/or a diastolic pressure of greater than 90mmHg.
Hypertension
determined by the product of cardiac out and systemic vascular resistance.
Blood pressure
amount of blood ejected from the left ventricle and measured in Lpm.
Cardiac output
It is a resistance to blood flow that is determined by the diameter of the blood vessels and vascular musculature.
SVR
Drugs that accelerate the rate of urine formation that results to the removal of sodium and water from the body.
Diuretics
What is the Systolic and Diastolic mmHg of a Normal Blood Pressure.
Less than 120 & Less than 80
What is the blood pressure category of higher than 180 of systolic and higher than 120 of diastolic.
Hypertensive Crisis
Give atleastone primary function of circulatory system.
> delivery of oxygen, nutrients, hormones, electrolytes, and other essential to cells and
> removal of carbon dioxide and metabolic wastes from cells. In addition, the system helps fight infection.
