Study Notes
Overview of the Circulatory System
- The circulatory system is comprised of the heart and blood vessels.
- Its primary function is to transport blood throughout the body.
Function of the Heart
- The heart pumps both oxygen-rich and oxygen-poor blood.
- The left side of the heart receives oxygen-rich blood from the lungs and distributes it to the body.
- The right side of the heart pumps oxygen-poor blood to the lungs for re-oxygenation.
Heart Rate
- Under resting conditions, the heart beats between 60-100 times per minute.
- During physical activity, the heart rate increases significantly to supply more oxygenated blood to the muscles.
Interaction with the Respiratory System
- The circulatory system works closely with the respiratory system to ensure oxygen delivery.
- While the heart circulates oxygen to muscles, the respiratory system is responsible for oxygen intake.
