MDCAT · CHAPTER 11
Circulation
Understand the heartbeat as a pressure-driven sequence and connect heart structure with pulmonary and systemic circulation.
Your study notes
01 / LESSON
Build the explanation.
- Trace blood through the four chambers and two circuits.
- Explain valve opening and closure using pressure differences.
- Relate electrical conduction to atrial and ventricular contraction.
02 / NOTES
The essentials, in one place.
- The right and left sides power pulmonary and systemic circuits.
- Pressure differences, not active valve movement, control one-way flow.
- The conduction system coordinates atrial then ventricular systole.
- Vessel structure reflects pressure, direction and exchange function.
03 / ACTIVITY
Test the idea by changing something.
Predict the result first, run the activity, then explain what changed and why.
04 / DIAGRAM
Make the connections visible.
Venae cavae return deoxygenated blood.
Pumps blood through the pulmonary artery.
Gas exchange oxygenates the blood.
Pumps blood through the aorta to the body.
Cover the labels, redraw the sequence or comparison, and explain each connection aloud.
