  1. The Respiratory and Circulatory System

  2. O2 O2 What is Respiration? O2 • The process in which the body brings in Oxygen and gets rid of Carbon Dioxide. CO2 CO2 CO2

  3. Respiratory System • Includes: • The Pharynx • The Larynx • The Trachea • The Bronchi • The Lungs • The Diaphragm

  4. Organs • Pharynx- A tube-like passage used by food, liquid and air. • Larynx- Airway to which the vocal cords are attached.

  5. Organs Larynx • Trachea- Tube that connects the Larynx to the lungs. • Bronchi- Two short tubes that branch into the left and right lungs. Trachea Bronchial Tubes

  6. O2 O2 O2 O2 O2 O2 O2 O2 O2 O2 Lungs CO2 CO2 • Organs that take in Oxygen and release Carbon Dioxide. • Contain Alveoli- Tiny grapelike clusters where Oxygen and Carbon Dioxide changes place. CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2

  12. Organs • Diaphragm- Muscles beneath the lungs that contracts and relaxes every time you breath. • This helps to pump the lungs allowing Oxygen to enter and Carbon Dioxide to leave.

  16. Respiratory Disease • Lung Cancer- Smoking is the leading cause of Lung Cancer. • Bronchitis- Inflammation of the Bronchial Tubes. • Causes shortness of breath, wheezing and coughing to bring up mucus. • Emphysema- Damage to the Alveoli that results in breathing problems and coughing.

  17. Respiratory Disease • Asthma- Inflammation of the Respiratory System resulting in wheezing and shortness of breath. • Triggers- Allergens such as pollen, dust and cigarette smoke.

  18. What is Circulation? • The process by which nutrients and oxygen are taken to cells, and carbon dioxide and waste are taken from cells.

  19. Cardiovascular System • Includes: • The Heart • Blood Vessels • Blood

  20. The Heart • The Heart pumps blood throughout the body. • Atriums- The upper chambers of the heart. • Ventricles- The lower chambers of the heart.

  21. Types of Circulation • Coronary Circulation- Supplies the heart with blood. • Pulmonary Circulation- Supplies the lungs with blood. • Systemic Circulation- Supplies the body with blood.

  22. Vessels • Arteries- Carries blood away from the heart. • Veins- Carries blood towards the heart. • Capillaries- Where arteries and veins connect. • Capillaries are very thin so O2 and CO2 can diffuse into and out of the cells.

  23. Capillaries Red Blood Cells move through capillaries one at a time! Artery Vein Body Cells

  24. What Makes up Blood? • Plasma- The liquid part of Blood- Mostly water. • Platelets- Cell fragments that helps blood clot. • Red Blood Cells- Transport O2 and CO2 throughout the body. • Contains Hemoglobin- Molecule that carries O2 and CO2. • White Blood Cells- Used to fight off infections.

  25. Function of Blood • Transports O2 and CO2 throughout the body. • Carries waste to the Kidneys. • Carries food nutrients to our cells. • Fight infections and heal wounds.

  26. Blood Types • A • B • AB • O

  27. Cardiovascular Diseases • Hemophilia- Disease that prevents people’s blood from clotting. • Anemia- Disease where not enough oxygen gets to the body cells. • Leukemia- Disease where the body makes too many white blood cells. • Arteriosclerosis- When fat deposits build up inside arteries. • Hypertension- When blood pressure is too high, making the heart work over-time.

  28. Preventing Cardiovascular Disease • Good diet, reduced stress, exercising and not smoking can reduce the chance of Cardiovascular Disease.

  29. Working Together • The Circulatory and Respiratory System work together to give Oxygen to all our body cells, and to get rid of Carbon Dioxide.
