Matching Exercise
- Perfusion
- The flow of blood through the lumen of a vessel.
- Hypertrophy
- Growth of muscle tissue secondary to increased work.
- Diastole
- Period of the heart cycle characterized by filling of the ventricles with blood.
- Systole
- The phase of the cardiac cycle characterized by contraction.
- Automaticity
- Characterized by independence from central nervous system control. Enables the heart to produce action potentials.
- Blood Pressure
- The tension of blood within the arteries.
- Shock
- A condition characterized by failure of the circulatory system to maintain adequate perfusion of vital organs.
- Tamponade
- Compression of the heart resulting from an increased volume of fluid in the pericardial sac.
- Beta-receptor
- A receptor which, when stimulated, increases heart rate and contractility, as well as dilates the bronchial tree and vascular smooth muscle.
- Contractility
- The ability of a muscle fiber to shorten or increase its tension.
- Depolarization
- Characterized by a change in polarity.
- Action Potential
- The change in the electrical potential of a membrane that occurs when a nerve or muscle cell is excited.
