• Pneumonia (Respiratory)

  Fluids stuck in airway which causes trouble breathing
• Stroke (Circulatory)

  caused by hemorrhage of build up in arteries blood flow to brain causing stroke
• Pancreatitis(Digestive)


  Pancreatitis is swelling of the pancreas. Pancreatitis

  causes abdominal pain, nausea, and vomiting.
• Red Blood Cells


  Transport Oxygen
• White Blood cells


  Respond to infection and increase when fighting infection
• Platelets (Thrombocytes)


  Play a role in blood clotting
• Differences between internal and external Inspiration

  Internal = exchange of oxygen & Carbon dioxide between blood and body tissues

  External = Exchange of oxygen and carbon dioxide between blood and alveoli/lungs
• Role of CO2 in regulating breathing and heart rate

  • if CO2 is high then pH is low, this triggers the nerves to send a signal to the medulla
  • medulla sends a signal to diaphram and intercostal muscles to increase breathing rate
  • this affects heart rate because heart rate beats faster to remove CO2 and get O2 into vessels and transport throughout the body to increase pH
• Stomach involved in chemical and physical digestion

  • The stomach has peristalsis which moves food
  • HCl kills microbes the activates the pepsin into pepsinogen and breaks down protein in the stomach
  • Peristalsis moves moves food so most of it is physically digested and protein enzymes gets the smaller bits chemicaly digested
• Comparing four chambers of the heart

  • Right Atrium is deoxygenated the blood then goes to Tricuspid
  • Right Ventricle is deoxygenated then blood goes to Pulmonary semi-lunar valve
  • Left Atrium is oxygenated then goes to bicuspid
  • Left Ventricle is Oxygenated and goes to aortre semi-lunar valve
• Arteries Structure and Function

  • Thick elastic wall High pressure
  • Carry oxygenated blood away from heart
• Veins structure and function

  • Thin Walls with valves, low pressure
  • Carry deoxygenated blood to heart
