Cardiovascular, circulatory and lymph: week 1 Flashcards
Chamber of the heart that receives deoxygenated blood from the body is the
Right atrium
Chamber of the heart that pumps oxygenated blood to the body is the
Left ventricle
Chamber of the heart that receives oxygenated blood from the lungs is the
Left atrium
Chamber of the heart that a pumps deoxygenated blood to the lungs is the
Right ventricle
Strongest changer of the heart is the
Left ventricle
The sustained elevation of systemic arterial blood pressure is
Hypertension
What stage of hypertension has a systolic reading of 160 or higher
Stage 2 hypertension
What is the normal range for blood pressure
120 / 80
Condition which the heart pumps out less blood then it receives is
Congestive heart failure
A condition in which the oxygen rich blood is stopped, blocked, or restricted to a specific part of the body
Ischemia
Irregular patterns in the beating of the heart or change in the force of the speed of the hearts contractions
Arrhythmias
What classification of drugs are used to increase the force of myocardial contractions without causing an increase in the consumption of oxygen
Cardiac glycosides
Classification of hypertension drugs are used to eliminate excess sodium and water via urinary tract
Diuretics
Classification of drugs allow more blood to exit the heart, preventing congestion and increasing cardiac output
Vasodilators
Classification of drugs block the conversion of AI to AII, keeping the blood vessels from constriction and blood pressure from increasing
ACE inhibitors
The heart pumps approximately how many gallons of blood per day
1,900 gal
What is a fluid filled sack that surrounds and perfects the heart
Pericardium
The inner most heart wall and covers the inside surface of the heart
Endocardium
Surrounds the heart and causes the chambers to contact
Myocardium
Beta 2 receptors are found in the
Lungs
Beta 1 receptors are found in the
Heart
Occurs when there is an insufficient blood flow to the heart via the right or left coronary artery
CAD Coronary Artery Disease
Type of drug breaks down blood clots by reversing clotting order and interfering with the synthesis of clotting factors
T-PA
Drug used as an antidote for heparin overdose
Protamine sulfate
A drug used an an antidote for thrombolytic overdose
Aminocaproic acid
Cholesterol is synthesized in the
Liver
“Bad” cholesterol
Low - density lipoproteins or LDN
“Good” cholesterol
High - density lipoproteins or HDL
Cholesterol level of 225 mg/dl would be considered
Borderline high cholesterol
Drugs used to prevent the progression of coronary artery disease by lowering plasma lipid levels
Angihyperlipidemics
Purpose of the heart is to pump what kind of blood though the body
Oxygen rich blood
The conduction system controls the what of the hearts contractions
Speed
A persons is considered to have normal blood pressure if their systolic reading is
Less than 120
Direct is lower blood pressure by decreasing And blood force against the vessel walls
Blood volume
Peripheral vasodilators work directly on blood vessels in what area treating moderate to severe hypertension
Arms & legs
Trade name for isoxsuprine HCL
Voxsuprine
Many ACE inhibitors have the suffix
Pril
Angiotensin I what affect on blood pressure
None
Cardiac glycosides main mechanism of action is to lock ATP inside the
Myocardium
What is known as a natural pacemaker
SA node
Blood pressure is measured in
Millimeters of mercury
Most commonly used diuretic for CHF
Thiazides diuretics
Pericardium
Double layer of serous and fibrous tissue, a fluid filled sac that surrounds and protects the heart
Right ventricle (RV)
Pumps deoxygenated blood to lungs to pick up oxygen and drop off waste
Right atrium (RA)
Receives deoxygenated blood from the lungs
Left ventricle
Strongest chamber, pumps oxygenated blood to rest of body and back to heart
Tricuspid valve
Located between RA and the RV
Pulmonary valve
Located between RV and the pulmonary artery
Mitral or bicuspid valve
Located between left atrium and left ventricle
Aortic valve
Located between left ventricle and aorta
Arteries
Blood vessels or tubes which oxygenated blood travels
Largest artery
Aorta
Veins
Carry deoxygenated blood, take blood back to heart then to lungs
Capillaries
Network of tiny blood vessels connecting arterioles and carrying oxygenated blood and nutrients to venules
Arterioles
Smallest arteries
