Study Notes
Cardiovascular System Morphology and Function
- Large Circulatory Loop End: The large circulatory loop ends in veins.
- Small Circulatory Loop End: The small circulatory loop ends in vessels.
- Venous Blood Flow in the Heart: Venous blood in the heart flows into the chambers.
- Coronary Blood Supply: The heart's blood supply branches from the aorta.
- Cardiac Septum Function: The heart is separated by a wall to prevent mixing of blood.
- Semilunar Valve Function: Semilunar valves are supported by muscles to ensure they close tightly.
- Atrioventricular Valve Function: The atrioventricular valve assists separation between ventricles and atria.
- Tendinous Cords Anchor Valves: Tendinous chords secure the valves in position to support function during contractions.
- Cardiac Cycle Measurements: The cardiac cycle can be charted and measured with electrocardiography (ECG) for diagnostic purposes.
- Heart Sound Characteristics: Contractions and relaxations within the heart can be described by characteristic sounds.
- Reasons for Heart Rate Changes: A faster heart rate can be symptomatic of certain conditions.
- Artery Branching: The brachiocephalic artery is a branching point for blood supply.
- Unpaired Organ Blood Supply: Abdominal organs, particularly those without paired counterparts, obtain their blood supply from specific large arteries.
- Veins of the Abdominal Cavity: Veins contribute to the transport of blood from the abdominal organs to the heart.
- Portal Vein Function: Blood collected from digestive organs flows into the portal vein.
