Definition
Systole is the first number of a blood pressure reading--refers to the amount of blood moved through the heart during contraction
Diasole is the second number (bottom number) and refers to the time between contractions, during which the blood enters the ventricles |
|
|
Term
|
Definition
| Amount of blood traveling thru the left ventricle and out to the body. |
|
|
Term
| List the path through the heart that blood travels |
|
Definition
Blood from body enters right atrium to right ventricle
Moves into pulmonary ARTERIESto lungs
Moves to pulmonary VEINS and into
Left atrium and ventricle to
Aorta to the body |
|
|
Term
| What do AV valves separate? |
|
Definition
| The atrium and ventricle of both sides of heart |
|
|
Term
| What do the SL valves separate? |
|
Definition
Semilunar valves separate the ventricles from the aortas, each containing 3 cusps.
Pulmonary Semilunar valve lies between right ventricle and pulomary trunk to lungs
Aortic semilunar valve lies between left ventricle and aorta to body. |
|
|
Term
| What does the second half of the heart beat signify (the dupp of lubb dupp) |
|
Definition
| Semilunar valve closure causing blood turbulence |
|
|
Term
| What is the average HR/minute |
|
Definition
|
|
Term
|
Definition
aka AV bundle
SA node creates an electrical current that travels to AV node, which works at a slower rate than SA to allow time for blood movement, creating a pause between lubb and dupp
Impulses are then sent to Bundle of His (which branch out to Purkinje fibers) and help to spread impulse to entire myocardium. |

Term
| Where are veins generally located |
|
Definition
Superficially and near skeletal muscle
This is why massage is done centripetally (toward center), to help move blood toward the heart |
|
|
Term
| What is the hepatic portal system? |
|
Definition
Part of the venous portal system (starts and ends with veins), it collects blood from digestive organs (stomach, intestines, gallbladder, spleen, pancreas) and delivers it to the liver for processing and storage.
The Portal Vein is formed by the union of superior mesenteric (from colon) and splenic (from spleen) veins.
The blood takes the detour through the liver before reaching the systemic circulatory system. |
|
|
Term
| What is the systemic circuit? |
|
Definition
Brings oxygenated blood from left ventricle to the body and back to the right atrium and to lungs through left ventricle.
