24
Q

Also called pulmonary or pulmonic valve

A

Right semilunar valve

25
Also called bicuspid
Left AV valve
26
Located at the entrance of pulmonary artery
Right semilunar valve
27
Located between Left atrium & left ventricle
Left AV valve
28
Located at the entrance of aorta
Left semilunar valve
29
Located between the right atrium and right ventricle
Right AV valve
30
Separates the right and the left ventricles
Interventicular septum
31
Partition that separates the right and the left atria
Interatrial septum
32
receives blood supply thru the left and right coronary arteries, and coronary veins return the oxygen depleted blood from the heart muscle back to the heart.
Coronary circulation
33
The force which was exerted by the blood on the walls of the vessel which is measured by the sphygmomanometer. The blood pressure is the difference between the systolic (pressure during contraction) and diastolic (pressure during relaxation).
Blood Pressure
34
A rhythmic throbbing resulting from the alternating expansion and contraction of the artery
Pulse
35
The average heart rate is 72 beats per minute (bpm) and the cardiac output refers to the volume of blood pumped per minute
Heart rate and cardiac output
36
"lubb" which is the first sound as the ventricles contract or the AV valves close and "dupp" or the second sound which is heard when the semilunar valves close and the ventricles relax.
Origin of heart sounds
37
Provides the graphical representation of the cardiac cycle's activity
Electrocardiogram (ECG)
38
Sends electric impulses throughout the myocardium which is initiated by the sinoatrial (SA) node (pacemaker)
Electrical conduction system
39
Systole (contraction) & diastole (relaxation) which lasts about 0.8 seconds
Cardiac cycle
40
Disorders of the circulatory system
1. Angina pectoris 2. Aortic stenosis 3. Bacterial endocarditis 4 . congestive heart failure 5 . Myocardial infarction 6. Pericarditis
41
Diagnostic tests for heart disorders
✓Arterial Blood Gases (ABG) ✓Aspartate aminotransferase ✓Oxaloacetic transaminase ✓Creatine Kinase (CK) ✓Creatine kinase (CK) ✓Digokin ✓Electrocardiogram (ECG or EKG) ✓Lactate dehydrogenase (LD) ✓Microbial cultures ✓Myoglobin ✓Potassium (K) ✓Triglycerides ✓Troponin T (Tnt)
42
the loop which consists of a system of blood vessels through which blood is circulated to the rest of the body
Vascular System
43
Two divisions of vascular system
1. Pulmonary circulation 2. Systematic circulation
44
Structure of the vascular system
✓Arteries ✓Arteriotes ✓Veins ✓Venules ✓Capillaries
45
Blood vessel structure (Layers) -outer connective tissue
Tunica Adventitia
46
Blood vessel structure (Layers) -middle, muscle and elastic fiber
Tunica media
47
Blood vessel structure (Layers) -inner, endothelial cells
Tunica intimia
48
Disorders of the vascular system
1. Aneurysm 2. Arteriosclerosis 3. Atherosclerosis 4. Embolism 5. Embolus 6. Hemorrhoids 7. Phlebitis 8. Thrombophlebitis 9. Thrombus 10.Varicose veins
49
Diagnostic Test of the vascular system
✓D-Dimer ✓Fibrin degradation products (FDP) ✓Lipoproteins ✓Prothombin time (PT) ✓Partial thromboplastin time (PTT/APTT) ✓Triglycerides
50
the red fluid that is transported throughout the body through the circulatory system.
Blood
51
Two functions of blood
1. Arterial Blood 2. Venous Blood
52
Carries oxygen away heart
Arterial blood
53
Carries carbon dioxide toward heart
Venous Blood
54
Human blood composed of ___________________Contains gases (02, CO2, N), minerals (Na, K, Ca, Mg), carbs & lipids, proteins, etc
Plasma ang other formed elements
55
a clear, straw-colored liquid portion of the blood which is 90% water
Plasma
56
Three components of human blood
1. Erythrocytes (red blood coll) - to transport gases 2. Leukocytes (white blood cell) - Fight For infections 3. Thrombocytes (platelets) - for blood clotting
