- Circulatory system has two main functions: transport and protection against disease
- Blood components include plasma, red blood cells, white blood cells, and platelets
- Circulatory process involves arteries, veins, and capillaries, with the heart acting as a unidirectional pump
- Heart has chambers with varying wall thickness, pressure, and specific functions
- Exercise leads to increased heart rate, cardiac output, and blood pressure, impacting the circulatory system
Understanding the circulatory system is important for understanding human biology and the impact of physical activity on the body.
