During physical activity, such as exercise, what physiological response directly aids in delivering more oxygen to muscle cells?
During physical activity, such as exercise, what physiological response directly aids in delivering more oxygen to muscle cells?
- reducing blood flow to minimize oxygen usage
- decreasing perspiration to maintain body temperature
- increasing heart rate to pump blood faster (correct)
- slowing down the breathing rate to conserve energy

Study Notes
Ordering Biological Structures
- The correct order of biological structures, from smallest to largest, is: cells, tissues, organs, and organisms.
Oxygen and Exercise
- When Javier exercises, his muscle cells need more oxygen.
- Increasing the heart rate will increase the flow of oxygen-rich blood to the muscles.
Sensory Observation
- The nervous system transmits sensory information from the environment to the brain.
Muscle Contraction
- The nervous system controls muscle contraction and relaxation, allowing for movement.
Blood Classification
- Blood is a system because it transports essential nutrients and removes waste products from the body's cells.
