Respiratory A & P test 3 flashcards
| Question | Answer |
|---|---|
| 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 |
