Static demand involves smaller groups of muscles under extreme resistance for brief period. An example is weight lifting. Dynamic training involves larger groups of muscles at lower resistance for extended periods of time. Examples are aerobic training
adapts to physical demands by enlarging, especially the left ventricle. Enlargement increases the cardiac output, the amount of blood pumped with each beat of the heart. The exact type of adaptation depends on the nature of the physical demand
No
Yes, blood pressure can be higher after exercise due to the increased demand on the heart and blood vessels during physical activity.

Cardiac enlargement is associated with dynamic training. The heart's response to static training is hypertrophy, thickening of the muscle walls of the heart

Thermodynamics involve heart-burns because of the gravity of the earth.
Defibrillators use static electricity to deliver an electric shock to the heart in order to restore normal heart rhythm in cases of cardiac arrest. The device generates a high-voltage charge that is discharged through the heart, allowing the heart muscle to contract in a coordinated manner and resume pumping blood effectively.
During exercise, the heart muscle's oxygen requirements increase significantly to meet the heightened demand for blood flow and energy. As physical activity intensifies, the heart pumps faster and harder, requiring more oxygen to support the working muscles. This increased demand is met by an increase in heart rate and stroke volume, ensuring that sufficient oxygen-rich blood is delivered throughout the body.
