Cardio - Chambers and Associated Great Vessels Flashcards
Hollow cavities or chamber of the heart:
- 2 atria (Recieve blood from veins)
- 2 ventricles (Pumps blood to arteries)
The primarily receiving chamber
- not important in the pumping activity of the heart
- Assist with filling the ventricles
Superior Atria
Think-walled, discharging chambers
- actual pumps of the heart
- blood is propelled into the circulation as they contract
Inferior Ventricles
- divides the heart longitudinally
- divides atria
Interatrial Septum
- divides the ventricles
Interventriculat Septum
- carries blood away from the heart
Arteries
- carries blood towards the heart
Vein
- receives oxygen-poor blood from the veins and pumps it out through pulmonary trunk
Superior and Inferior Vena Cava
- carry blood to othe lungs, here oxygen is picked up and carbon dioxide is unloaded
Pulmonary Arteries
- transfers oxygenated blood from the lungs to the left side of the heart
Pulmonary Veins
- carries blood away from the heart towards all body tissues
Aorta
- wall is thicker
- much more powerful since it pumps blood over the much longer systemic pathway through the body
Left Ventricle
The circuit
- from right ventricle
- to lungs
- back to left atrium (to carry blood)
- to lungs (for blood exchange)
- return it to the heart
Pulmonary Circulation
Pulmo kasi may lungs
THe Circuit
- from left ventricle (through the body tissues)
- back to atrium (that supplies oxygen and nutrient-rich blood)
- to all body organs
Systemic Circulation
What happens in Pulmonary CIrculation?
The circuit
- from right ventricle
- to lungs
- back to left atrium (to carry blood)
- to lungs (for blood exchange)
- return it to the heart
