plus summaries)
1. 3 main components of the CVS: Heart, Blood, and vessels
2. Main functions of the CVS: Transport of Oxygen to tissues from lungs Transport of
CO2 from tissues to lungs
Transport of nutrients Transport of
waste products
Transport of Hormones from endocrine glands Transport & radiation
of heat
3. what aspect of cardiac muscle allow it to respond to stimulation differently than skeletal
muscle: Involuntary, branched, intercalated disk
4. what phase of the cardiac cycle does the coronary artery fill with blood: -
Ventricle relaxation due to backward wave will fill the coronary arteries (diastole)
5. EKG Waves: P: atrial activity PR:
AV node
QRS: ventricular activity
T: repolarization of the ventricles
6. ST elevation and ST depression: ST elevation (myocardial infraction) ST De- pression (Cardiac
ischemia)
7. Depolarization of cardiac muscle: slow leak of sodium, calcium rushes in. Repolarization of
Potassium rushing out.
8. Main differences between arteries and veins: Veins (Thinner, less pressure, less smooth muscle
and connective tissue)
Arteries (Thicker, more pressure, deeper in the body, no valves).
9. Test to determine someones vascular health: ultrasounds
10.Basic components of blood: plasma,
formed elements: red blood cells, white blood cells, platelets
11.The main purpose of the respiratory system is: To supply oxygen to the body, To eliminate

12.baroreceptors: pressure receptors
13.chemoreceptors: chemical receptors
