Body Systems interactions

What happens to blood flow during physical activity?

• Blood flow decreases to conserve energy.

• Blood flow remains the same regardless of activity level.

• Blood flow increases to deliver more oxygen and nutrients to active muscles.

• Blood flow is redirected away from the muscles to the digestive system.

What is the role of the skeletal system in movement?

• The skeletal system protects vital organs from injury.

• The skeletal system produces hormones that regulate metabolism.

• The skeletal system provides structure and support for the body, allowing muscles to pull on bones for movement.

• The skeletal system stores fat and minerals for energy.

What happens to your body during exercise?

• Your heart rate decreases, blood flow decreases, and less oxygen is delivered to muscles.

• Your heart rate increases, blood flow rises, and more oxygen is delivered to muscles.

• Your body temperature drops, and muscles become less active.

• Your heart rate remains the same, and blood flow is unaffected.

How do the respiratory and circulatory systems work together?

• The respiratory system brings oxygen into the body, which the circulatory system then transports to cells.

• The circulatory system filters toxins from the blood while the respiratory system absorbs carbon dioxide.

• The respiratory system regulates body temperature while the circulatory system provides nutrients to cells.

• The circulatory system is responsible for gas exchange while the respiratory system pumps blood throughout the body.

What is the role of the circulatory system in the body?

• To provide structural support to the body

• To transport oxygen, nutrients, hormones, and waste products throughout the body

• To facilitate digestion and absorption of food

• To regulate body temperature and fluid balance

What systems are involved in digestion?

• The digestive system and the respiratory system

• The digestive system, muscular system, and circulatory system

• The digestive system and the nervous system

• The digestive system and the endocrine system

What is the function of the respiratory system?

• To circulate blood throughout the body.

• To take in oxygen and expel carbon dioxide from the body.

• To digest food and absorb nutrients.

• To regulate body temperature.

How does the body respond to a pinch?

• The body ignores the pinch and continues its activity.

• The nervous system detects the pinch, sends a signal to the muscular system, which then contracts to move the arm away.

• The skin absorbs the pinch and no response occurs.

• The body immediately falls asleep to avoid feeling pain.

What is the importance of oxygen for muscles during exercise?

• Oxygen is essential for muscles to produce energy efficiently during exercise.

• Oxygen helps muscles to recover after exercise.

• Oxygen is not important for muscle function during exercise.

• Oxygen increases muscle size during exercise.

How do the nervous and muscular systems work together?

• The nervous system sends signals to the muscular system to initiate movement, allowing the body to respond to stimuli.

• The muscular system generates signals that the nervous system interprets for movement.

• The nervous system and muscular system operate independently without interaction.

• The muscular system controls the nervous system to regulate body functions.
