Answer: During exercise, several organ systems respond to the stimuli produced. The organ systems involved include:
1. Muscular System: The muscles contract and relax to produce movement and generate heat.
2. Cardiovascular System: The heart rate increases to pump more oxygenated blood to the working muscles. Blood vessels dilate to increase blood flow to the muscles and remove waste products.
3. Respiratory System: The rate and depth of breathing increase to supply more oxygen to the muscles and remove carbon dioxide.
4. Nervous System: The brain and spinal cord coordinate muscle contractions and regulate heart rate and breathing.
5. Endocrine System: Hormones such as adrenaline and cortisol are released to increase energy production and mobilize stored nutrients.
6. Skeletal System: The bones provide support and protection for the muscles and organs involved in exercise.
7. Integumentary System: Sweat glands produce sweat to cool the body during exercise.
8. Digestive System: Blood flow to the digestive organs decreases during exercise to redirect blood flow to the working muscles.
