|
Blood vessels delivering blood to right and left atria |
Right atrium: superior and inferior vena cava and coronary sinus Left atrium: blood from lungs via four pulmonary veins |
|
|
Venticles: thickness and function |
Left ventricle thicker, pumps blood to systemic circuit (higher pressure, higher resistance) Right ventricle thinner, pumps blood ton pulmonary circuit (shorter distance, less resistance, less pressure) |
|
|
Gut to liver blood flow |
Oxygenated blood to gut, picks up nutrition, goes via Hepatic portal vein to liver as deoxygenated blood. |
|
|
Blood pressure in chambers |
RA: 5mmHg LA: 8mmHg RV: 27mmHg LA: 120mmHg |
|
|
Interventricukar sulcus |
Separates the ventricles on the exterior surface (anterior and posterior) |
|
|
Blood volume across body circuits |
Pulmonary: 9% Heart: 7% Systemic: 84% Total -> 5L Output 1 pump: 5L/min (at rest) |
|
|
Ventricular pump: Filling phase |
Walls of ventricles expanding, volume of blood increasing. Outlet valve by artery stops blood going backwards into ventricles. Inverse relationship b/w blood volume and wall expansion |
|
|
Ventricular pump: ejection phase |
Walls contract, blood volume decrease. Inlet valve prevents valve movie back into veins |
|
|
Ejection from right ventricle |
Blood goes to pulmonary trunk then out right and left pulmonary arteries |
|
|
Ejection from left ventricle |
Into aortic valve to aorta and systemic arteries |
