A & P 3 flash cards

Respiratory A & P test 3 flashcards

What percentage of the blood is solid and liquid 45% solid & 55% liquid
Function of the red blood cells Carries oxygen and carbon dioxide
name 5 white blood cell types Neutrophils, Eosinophils, Basophils, Lymphocytes, Monocytes
Increased white blood cell count shows signs of Infection (Bacterial)
Most numerous type of white blood cells Neutrophils
Function of platelets (Thrombocytes) Seals small tears in blood vessels (Blood clotting)
5 components of blood plasma Water 93%, Proteins, electrolytes, food substances, Respiratory gasses, Individual hormones, waste products
name of abnormally low RBC Anemia
what are two types of causes for Anemia Losing red blood cells, and not making red blood cells
What is the most common reason for Anemia Hemmoraging
What is the Normal RBC count 4 to 6 million (5 million)
What is the name for High RBC count Polycythemia
Normal range for white blood cells 4 to 11 thousand
Term that means below normal range for white blood cell count Leukopenia (under 4 thousand)
Term for higher than normal range white blood cell count Leukocytosis (over 11 thousand)
Define thrombus stationary blood clot
Define Embolus Moving blood clot
Define Anticoagulant Against clotting
Define thrombolytic Clot buster
give normal Hemoglobin for male and female Male 14 to 16 gram %, Female 12 to 15 gram %
What is the function of hemoglobin Carries oxygen to tissues and CO2 back to lungs
Two pumping chambers of the heart Left ventricle, right ventricle
what are the two sets of valves in the heart Atrioventricular valves, Semilunar valves
Trace conduction pathway through the heart SA node, Internodal tracts, AV node, bundle of HIS, right and left bundle branches, purkingie fibers
What is MI Myocardial infarction
What is CABG Corinary Artery Bipass Graph
What is ECG Electro cardiogram
What is EEG electro encephelogram
Trace the flow of blood through the heart from the vena cava to the Aorta Vena cava, right atrium, tricuspid, right ventricle, pulmonary semilunar valve (Pulmonic), pulmonary artery, lungs, pulmonary vein, left atrium, mitral valve (Bicuspid), left ventricle, aortic valve, aorta
3 layers of the heart Visceral paricardium (epicardium), myocardium, endocardium
two upper chambers of the heart Atria
two lower chambers of the heart ventricles
two pumping chambers of the heart ventricles
the walls that seperate these chambers are called septum
Atrioventricular valves include Right side tricuspid valve, left side bicuspid (mitral) valve
The right heart pumps blood to the lungs (pulmonary circulation)
the left heart pumps blood to all parts of the body (Systemic circulation)
Pulmonary artery pressure is 25 systolic/ 8 diastolic
% of venous blood that drains into right atrium 95%
% of venous blood that drains into Thebesian veins 5%
Thebesian veins empty into the left heart
Thebesian veins create anatomic shunt (Blood bypasses lungs without gaining oxygen)
Blockage of the coronary artery leads to MI (Myocardial infarction)also known as a heart attack
Electrocardiography Depolarization contraction (Systole)
Electrocardiography Repolarization relaxation (diastole)
Electrocardiography P wave begin atrial depolarization
Electrocardiography QRS Ventricular depolarization
Electrocardiography T wave ventricular repolarization
Atrial repolarization is hidden behind QRS complex
ECG traces the electrical imulse through the heart
When the hearts electrical pulse is messed up arrhythmmia occurs
Arrhythmia means the heart is out of it's normal rhythm
Heart block refers to blockage of electrical impulses which cause heart contractions
what may be indicated to correct the electrical pulses & make them regular pace maker
Heart failure inability of heart to pump enough blood due to weak heart muscle
Heart failure is caused by cardiomyopathy, valve disorders, myocardial infarction
poor myocardial tissue perfusion ischemia
complete coronary blockage results in necrosis (Tissue death)
left ventricle failure CHF (Congestive heart faiure)
Clinical sign of left ventricle failure pulmonary edema
right ventricle failure cor pulmonale
clinical sign of right ventricle failure distended neck veins
