    • What are the responses to one session of exercise on the body systems?
      • Muscular: Increased blood flow, mineral uptake, increased temperature
      • Skeletal: Increased strength, improved flexibility
      • Cardiovascular: Increased heart rate, increased stroke volume, increased blood pressure, increased oxygen delivery
    • How many responses should be listed for the muscular system?
      3
    • How many responses should be listed for the cardiovascular system?
      4
    • What is the function of the sinoatrial node (SAN)?
      It sends impulses to contract the heart
    • What does the atrioventricular node (AVN) do?
      Acts as a buffer that slows down signals
    • What is the role of the Bundle of His?
      Transports electrical impulses from the AVN
    • What do Purkinje fibres do?
      They cause ventricles to contract and pump blood
    • What are the differences between the sympathetic and parasympathetic nervous systems?
      • Sympathetic: Prepares body for intense activity, increases heart rate
      • Parasympathetic: Calms the body, decreases heart rate
    • What is cardiac hypertrophy?
      Enlargement of the heart muscle
    • What happens to resting heart rate due to exercise?
      It decreases
    • What is stroke volume?
      Volume of blood ejected from the heart
    • What happens to blood pressure during exercise?
      It increases
    • How does regular exercise affect resting blood pressure?
      It decreases resting blood pressure
    • What is the name given to the contraction of the atria?
      Atrial systole
    • What is the name given to the contraction of the ventricles?
      Ventricular systole
    • What is the pathway of blood through the heart?
      1. Deoxygenated blood enters through vena cava
      2. Blood goes to right atrium
      3. Blood flows to right ventricle
      4. Blood is pumped to lungs via pulmonary artery
      5. Oxygenated blood returns through pulmonary vein
      6. Blood enters left atrium
      7. Blood flows to left ventricle
      8. Blood is pumped to the body via aorta
    • What is the function of heart valves?
      Stop backflow of blood
    • What is the role of the septum in the heart?
      Separates the left and right chambers
    • How does the structure of the heart support its function?
      Chambers and valves ensure efficient blood flow
    • What is the impact of high blood pressure on the heart?
      Heart works harder to pump blood
    • What are the symptoms of low blood pressure?
      Dizziness and fainting
    • What is the effect of dehydration on body temperature?
      Body temperature rises above normal
    • What happens when muscles contract in terms of heat production?
      Heat is produced as a byproduct
    • How does the body regulate temperature during exercise?
      Through sweating and increased blood flow
    • What is the role of the medulla oblongata?
      Controls heart rate and breathing
    • What is the significance of increased capillarization during exercise?
      Enhances oxygen delivery to muscles
    • What is the impact of increased blood volume on performance?
      Improves oxygen transport and temperature regulation
    • What is the function of the right atrium?
      Receives deoxygenated blood from the body
    • What is the function of the left ventricle?
      Pumps oxygenated blood to the body
    • What is the role of the pulmonary artery?
      Carries deoxygenated blood to the lungs
    • What is the role of the pulmonary vein?
      Returns oxygenated blood to the heart
    • What is the function of the aorta?
      Distributes oxygenated blood to the body
    • What is the significance of the heart's electrical conduction system?
      Coordinates heart contractions for effective pumping
    • How does the heart adapt to regular exercise?
      Increases efficiency and strength of contractions
    • What is the role of the valves in the heart?
      Prevent backflow of blood during contractions
    • What is the impact of exercise on the cardiovascular system?
      Improves heart function and blood circulation
    • What is the function of the right ventricle?
      Pumps deoxygenated blood to the lungs
    • What is the role of the left atrium?
      Receives oxygenated blood from the lungs
    • What is the significance of the septum in the heart?
      Separates oxygenated and deoxygenated blood
    • What is the pathway of blood from the body to the lungs?
