|---|---|---|---|---|---|
| Pericardium | Double-walled triple-layered sac, adheres to heart's outer surface & confines heart to its position
🗑
|
||||
| Myocardium | Contracting muscle layer
🗑
|
||||
| Endocardium | Lines chambers, covers valves
🗑
|
||||
| What is the function of the Inferior Vena Cava? | Returns deO2 blood from lower body to the Right Atrium
🗑
|
||||
| What is the function of the Superior Vena Cava? | Returns deO2 blood from upper body to Right Atrium
🗑
|
||||
| What is the function of the Pulmonary trunk & arteries? | Sends deO2 blood to lungs from Right Ventricle
🗑
|
||||
| What is the function of the Pulmonary veins? | Sends O2 blood to Left Atrium from lungs
🗑
|
||||
| What is the function of the Coronary Sinus? | Sends deO2 blood to Right Atrium from heart
🗑
|
||||
| What is the function of the Aorta? | Sends O2 blood to systemic circulation
🗑
|
||||
| How do Atria & Ventricles differ in function? | Atria RECEIVES blood from systemic circ. & lungs. Ventricles SEND blood to systemic circ. & lungs.
🗑
|
||||
| How are arteries & veins different? | Arteries take O2 AWAY from heart(except pulmonary & umbilical arteries). Veins bring deO2 blood to the heart(except pulmonary & umbilical veins).
🗑
|
||||
| What are the names of all of the Semilunar heart valves? | Pulmonary SL & Aortic SL
🗑
|
||||
| What are the names of all of the Atrioventricular heart valves? | Right AV valve = Tricuspid, Left AV valve = Bicuspid(mitral)
🗑
|
||||
| What is the Cardiac Cycle? | A complete heart beat. 2 atria contract while 2 ventricles relax < 2 ventricles contract while 2 atria relax < heart relaxes/all 4 chambers relax.
🗑
|
||||
| Explain the P, QRS, & T waves. | P: atrial depol. QRS: vent. depol. T: vent. repol.
🗑
|
||||
| What is the position of each heart valve during atrial & ventricular systole? | Atrial Systole: AV valves open & SL valves closed. Ventricular Systole: AV valves closed & SL valves open.
🗑
|
||||
| What does "Lubb" & "Dupp" represent? | Lubb: 1st sound (S1) Closure of AV Valves & Dupp: 2nd sound (S2) Closure of SL Valves
🗑
|
||||
| What is the relationship between Cardiac Output, Stroke Volume, & Heart Rate? | CO = SV x HR
🗑
|
||||
| What are the Primary, Secondary, & Tertiary factors affecting HR? | Primary: Normal demands(exercise, etc), abnormal demands(congenital cond. or tissue damage) Secondary: Autonomic NS, hormones, Tertiary: Other factors(temp, pain, emotions, age, gender, fever, etc)
🗑
|
||||
| What is the difference between semilunar & atrioventricular heart valves? | Semilunar: consists ONLY of cusps, each has 3 cusps. Prevent backflow of blood to ventricles. Atrioventricular: consists of cusps, chordae tendinae, and papillary muscles. Prevent backflow of blood to atria.
🗑
|
||||
| What is Systole? | contraction of the atrioles & ventricles
🗑
|
||||
| What is Diastole? | relaxation of the atrioles & ventricles
🗑
|
||||
| What is Isovolumetric Contraction & Relaxation? | For 0.05sec all 4 valves are closed - this occurs twice in the cardiac cycle
🗑
|
||||
| Duration of one heart beat? | 75 beats/min; 0.8sec (0.4sec all 4 chambers in diatole, 0.1sec atria contact, 0.3 venticles contract)
🗑
