where is the heart located? - CORRECT ANSWERS - anterior to and between the lungs in the
mediastinum
-The apex is above the diaphragm tilted slightly left of the midline
- Mechanical pump regulated by electricity
heart wall - CORRECT ANSWERS •3 layers of pericardial
membranes:
1. Fibrous pericardium
2. Parietal pericardium: covering on the outside
3. Visceral pericardium: covering over the heart
•Myocardium: pumps the heart (heat m.)
•Endocardium: lining on the inside of the heart
how many ml of fluid should be in the pericardial space? - CORRECT ANSWERS between 2-
10ml anything more can be fluid overload changing the hearts ability to pump
automaticity - CORRECT ANSWERS The ability of the heart to generate and conduct
electrical impulses on its own.
excitability - CORRECT ANSWERS response to stimulation
conductivity - CORRECT ANSWERS the ability of the heart cells to receive and transmit an
electrical impulse (communicate)
contractility - CORRECT ANSWERS the ability of the heart to contract

refractoriness - CORRECT ANSWERS period of recovery that cells need after being
discharged before they are able to respond to a stimulus
How many chambers does the heart have? - CORRECT ANSWERS 4 chambers
• right: atria, ventricle
• left: atria, ventricle
cardiac circulation - CORRECT ANSWERS blood comes from superior and inferior vena cava
→ inters the right atrium → goes through the tricuspid valve → goes into the right ventricle
→ blood goes through through pulmonary valve → travels into the pulmonary artery
(deoxygenated) → travels out into the lungs → returns through the left pulmonary veins →
enters in through the left upper atrium → fills and passes through the mitral/bicuspid valve
→ fills into the left ventricle → blood goes through the aortic valve → then travels into the
aorta → blood perfuses the heart through the coronary arteries
Coronary Arteries - CORRECT ANSWERS •Supply oxygen to the myocardium
•Right and left branches come off the ascending aorta.
•Blockage of coronary artery causes ischemia or infarction (hypoxia - leading to necrosis)
(know the right and left - and that they perfuse the heart during diastole)
When are coronary arteries perfused? - CORRECT ANSWERS during diastole - when the
Aortic valve closes (resting)
Systole - CORRECT ANSWERS = Squeeze (contract)
• Lub: hearing the closure of the tricuspid/bicuspid valves (two biggest valves)
• 1/3 of cardiac cycle

• Contraction and emptying of atria and ventricles
Diastole - CORRECT ANSWERS = Relax (dilate)
• Dub
• 2/3 of cardiac cycle: heart is resting 2/3 of the time which means the heart is getting blood
and O2 perfused to it 2/3 of the time (this is good).
• Relaxation and filling of atria and ventricles
• Coronary arteries perfuse heart
Electrical Conduction - CORRECT ANSWERS • Mechanical Function of the heart is regulated
by electrical activity
• The myocardium responds to the
electrical impulses of special cells.
• Sinoatrial (SA) node generates impulse
• Impulses travel to the atrioventricular (AV) node
• Down the bundle of His, right and left
• Into the Perkinje fibers
Cardiac Cycle - CORRECT ANSWERS • Beginning of one heartbeat to the beginning of the
next
• At the beginning of systole, the
ventricles contract forcing the AV
valves to close (S1) & semilunar valves to open (AORTIC/PULMONIC = SEMILUNAR)
• At the end of systole/beginning of
diastole the semilunar valves close
(S2) and the AV valves open.

Arterial: vascular system - CORRECT ANSWERS • Delivers oxygen, nutrients, chemicals, and
body defense substances to tissues
• Delivers cellular wastes to excretory organs (kidneys and lungs)
• Contribute to temperature regulation by directing blood to skin or away from skin
• High pressure system
Venous: vascular system - CORRECT ANSWERS • Returns blood to the heart
• 2 series
• Deep veins run next to arterial system
• Superficial veins run parallel to subcutaneous tissue
• Can accommodate large shifts in volume w/ minimal venous pressure changes
• Valves prevent backflow
• Skeletal muscle contraction helps push blood forward in venous system
• Hydrostatic pressure
• Delayed venous return when pt is upright
• Increased return when lying down
Blood Pressure - CORRECT ANSWERS = Force of blood exerted against vessel walls
• Determined by cardiac output (CO = HR X SV) and vascular tone
- Normal:
• Systolic < 120
• Pressure during systole
• Diastolic < 80
• Pressure during diastole
