How many gallons of blood does your heart pump each day?
What do Low-Density Lipoproteins(LDL) do?
Carries majority of cholesterol in blood
*known as "bad cholesterol"
What does High-Density Lipoproteins (HDL) do?
Carries cholesterol away from arteries to liver for metabolization and excretion
*known as "good cholesterol"
What are Triglycerides?
fat in food & body
converted from calories & stored
used for energy between meals
Myocardial arteries are called what?
What is the higher of the 2 readings and caused by the contraction of the ventricles?
What is the lower of the 2 readings and is the measure of the heart at rest?
What is the optimal BP reading?
<120/80 mm Hg
What system regulates heart rate?
What is Coronary Artery Disease?
The build up of plaque inside the coronary arteries which damages the inner layers which lowers BP
Creates imbalance between oxygen supply and demand
What is Arteriosclerosis?
Type of CAD that hardens arterial walls and decreases blood flow
Cholesterol deposits (plaque) on the arterial walls
What is Angina Pectoris?
A type of CAD that involves the blockage of coronary arteries
What is Acute Coronary Syndrome?
A spectrum of coronary artery diseases
Rupture of atherosclerotic plaque clot in coronary arteries
What is the valve between the right atrium and ventricle?
What is the valve between the left atrium and ventricle?
What is the valve between the left ventricle and the aorta?
What is the Valve between the right ventricle and the pulmonary artery?
What is Cardiomyopathy?
Structure/functional abnormality of the myocardium
Results in loss of muscle efficiency/heart function
What is Congestive Heart Failure?
Heart cannot pump enough blood/oxygen to organs
What is a Heart Murmur?
Abnormal Heart Sound
What is Rheumatic Fever?
What is Arrhythmias?
Any abnormal heartbeat
What are the three types of Arrhythmias?
What is the only vein in the body that carries oxygenated blood?
What is the only artery in the body that carries deoxygenated blood?
What is a Stroke?
Loss of bodily functions bc of insufficient supply of blood to brain
Blood obstructed->brain loses oxygen supply->brain tissue dies
What is Peripheral Vascular Disease?
Blood vessels outside the <3 affects peripheral circulation
What is the route of blood traveling through the heart?
blood comes in
2. from right atrium through the tricuspid valve into right ventricle
3. from right ventricle through the pulmonary valve to the pulmonary artery
4. to the lungs to become oxygenated
5. returns through pulmonary veins to the left atrium
6. from left article through mitral valve to left ventricle
7. From left ventricle through aortic valve to the aorta
8. oxygenated blood is distributed to the body
What kind of muscle is the myocardial?
Which valve controls the volume of blood being distributed to the body?
Where is the site of oxygen and nutrient exchange?
What does White blood cells do?
What do Platletts?
What is Plasma?
Fluid which everything is carried in
What do kidneys do when it comes to cardio output?
Affect BP by increasing or decreasing urine output
Which 2 medications disrupt coagulation?
What are the symptoms of Peripheral Vascular Disease
What is Hypertension?
What is Hypotension?
BP is low
What is Hyperlipidemia?
Metabolic abnormalities resulting in elevated cholesterol
This leads to artery plaque
What is Hypovolemic Shock?
Low bood volume shock caused by uncontrolled internal or external bleeding
What is Thromboembolic Disease?
What is Endocarditis?
inflammation of the heart lining valves caused by Valve malformation
What is Cardiac Arrest?
Cessation of heartbeat and respiration
CPR can restore.
What is Bradycardia?
Slow heart rate
What is Tachycardia?
Fast heart rate
What is Atrial fibrillation?
a beat thats rapid and shallow in a quivering motion
prevent the heart from filling or pumping blood
What is Flutter?
Rapid or chaotic heart rate
What is a Ventricular fibrillation?
*most serious form of arrhythmia*
ventricles stop filling w/blood
blood stops going to body
5 types of Arrhythmias
Whats the danger with Thromboembolic Disease?
If the build up in varocose veins becomes lose it can travel and cause coronary or lung blockage.
Characterized by chest pain that feels "like an elephant sitting on chest"
Inflamation of the bladder
Hardening of the arteries that can result in decreased blood flow
Condition characterized by inefficient pumping of blood by the heart
Chestive Heart Failure
Condition in which plaque builds up inside the coronary arteries
Coronary Artery Disease
Inflamation of the bladder
Presence of microorganisms in the urine
Urinary Tract Infections
Swelling of the kidneys caused by an infection
Inflammation of th heart lining and valves
Insufficient supply of blood to a part of the brain
Structural or functional abnormality of the heart muscle
Clotting Process step 1
1. Platelets activated by damaged blood vessels
2. platelets adhere to exposed collagen of blood vessel wall
3. Platelets get sticky and adhesive
Clotting process step 2
1. platelets stimulate coagulation factors
2. Cascade is initiated
- Vit K
- 13 clotting factors
- factors I, II, V, XIII
-Fibrinogen is converted into filaments of fibrin
Clotting Process Step 3
1. Fibrin filaments from meshwork
2. Meshwork traps platelets, RBCs and WBCs
3. Blood vessel is plugged
4. Fibrin contracts to form sold clot
Clotting Process Step 4
1. Clot begins to dissolve
2. Fibrinolysin breaks down fibrin meshwork
3. Soluble elements are scavenged and removed
What does CBC stand for?
Complete Blood Count
What is Blood Dyscrasias?
Drug-induced injuries or disorders of the blood
Decrease number of platelets
