  1. RespirationandCirculation

  2. We will cover • Metabolism • Lungs • Mechanics of Breathing • Blood • Heart • Circulation • Summary

  3. Healthy Cells Food & O2 Energy LIFE Metabolism Living Body

  4. Epiglottis Trachea Bronchus Pleural Cavity Bronchiole Heart Diaphragm Airway & Lungs

  5. Bronchiole Capillaries Alveoli Airway & Lungs

  6. Trachea Lungs Diaphragm Inspiration Respiration

  7. Respiration Expiration

  8. Lung Capacities • Total Volume = 6.5 Litres • Tidal Volume = At rest, varies 0.5 - 2.5 Litres • Vital Capacity = At work, can be as much as 4.5 litres • Residual Volume = After max. expiration - still contains 1.5 Litres

  9. Blood • Plasma - Carries CO2 waste • Red Corpuscles - Haemoglobin • White Corpuscles - Fight Infection • Platelets - Aid in Clotting

  10. Deoxygenated Blood to each Lung Arterial Blood to Head - Trunk - Limbs Oxygen “Rich” Blood from each Lung Venous Blood from Head - Trunk - Limbs Right Atrium Left Atrium High Pressure (Left) Side Low Pressure (Right) Side Right Ventricle Left Ventricle The Heart

  11. Brain Carotid Artery Jugular Vein Aorta Brachial Artery Heart Lung Kidney Liver Radial Artery Femoral Artery Intestines Circulation

  12. Summary • Metabolism • Lungs • Mechanics of Breathing • Blood • Heart • Circulation

  13. Questions

  14. The Process of Metabolism is? • Where food & O2 are converted into energy • Where O2 combines with the blood • Where waste products are stored

  15. The Process of Metabolism is? • Where food & O2 are converted into energyMetabolic rate can vary with individuals • Where O2 combines with the blood • Where waste products are stored

  16. The Diaphragm is • The flap that stops food going into the lungs • A strong muscular partition separating chest from abdomen • A strong fibrous muscle that separates the lungs

  17. The Diaphragm is • The flap that stops food going into the lungs • A strong muscular partition separating chest from abdomenFlexing of the diaphragm is part of the breathing mechanism • A strong fibrous muscle that separates the lungs

  18. The correct route by which air travels into the blood is? • Mouth - Trachea - Bronchioles – Alveoli • Nose - Bronchi - Bronchioles - Alveoli • Mouth/Nose - Trachea - Bronchi - Bronchioles - Alveoli - Capillaries

  19. The correct route by which air travels into the blood is? • Mouth - Trachea - Bronchioles – Alveoli • Nose - Bronchi - Bronchioles - Alveoli • Mouth/Nose - Trachea - Bronchi - Bronchioles - Alveoli - Capillaries

  20. The location for the interchange of gases is at the junction of • The Alveoli of the blood Capillaries • The Pleura of the blood veins • The Bronchioles

  21. The location for the interchange of gases is at the junction of • The Alveoli of the blood Capillaries • The Pleura of the blood veins • The Bronchioles

  22. Haemoglobin is contained in the blood content, is it in • The White Corpuscles? • The Platelets? • The Red Corpuscles?

  23. Haemoglobin is contained in the blood content, is it in • The White Corpuscles? • The Platelets? • The Red Corpuscles?White corpuscles fight infection. Platelets are a clotting agent.

  24. The "High Pressure" section of the heart consists of • The Right & Left Ventricle • The Left Atrium & Left Ventricle • The Right Atrium & Right Ventricle

  25. The "High Pressure" section of the heart consists of • The Right & Left Ventricle • The Left Atrium & Left Ventricle • The Right Atrium & Right Ventricle
