  1. Respiration and Excretion

  2. The respiratory system is what brings oxygen into your body and moves it around to your cells. It then expels waste from your body in the form of carbon dioxide.

  3. Define Key Terms page 410 • Respiration • Cilia • Pharynx • Trachea • Bronchi • Lungs • Alveoli • Diaphragm • Larynx • Vocal cords We already talked about the respiratory system…BREATHING…. But you need practice with the key terms.

  4. Respiration…… • What gases are exchanged by the respiratory system? • Oxygen and Carbon Dioxide!!! • The path of air….. • Nose…Pharynx…Trachea…Bronchus… • To the lungs!

  5. Gas exchange in the alveoli… • After air enters and alveolus, oxygen passes through the wall of the alveolus and then through the capillary wall into the blood. Carbon dioxide and water pass from the blood into the alveoli. • The whole process is known as gas exchange! What muscles are involved in breathing? The rib muscles and diaphragm.

  6. Excretory System…Key Terms • Excretion • Urea • Kidney • Urine • Ureter • Urinary bladder • Urethra • nephron

  7. The excretory system is the system in the body that collects wastes produced by cells and removes the waste from the body!

  8. How do the kidneys filter waste? • Open book to page 427 Kidneys

  9. Homeostasis: The body’s way of keeping it’s own 98.6 degree temperature despite the different temperatures of the environment. • Excretion maintains homeostasis by keeping the body’s internal temperature stable and free of harmful levels of chemicals. In addition to the kidneys, organs of excretion that maintains homeostasis include the lungs, skin, and liver.
