  1. Aim: How does the Human Respiratory System maintain homeostasis? HW #18 Read Text pages 956 to 963 Pg.963 section 37-3 ans. ques. 1-5 Pg.968 ques. 19-22 Complete sentences, neatness counts

  2. Respiration can be described… At the cellular level – oxygen is used to break down glucose in the production of the high energy compound ATP (occurs in the mitochondria of the cell) Groups: formula for aerobic respiration At the organ level – structures bring air containing oxygen into the body where it can be transferred to the red blood cells.

  3. Figure 37-14 The Respiratory System Trace a molecule of oxygen to the capillary in the alveolus Section 37-3 Pharynx Nose Larynx Trachea Mouth Bronchiole Lung Epiglottis Bronchus Alveoli Bronchioles Diaphragm Capillaries Edge of pleural membrane

  4. Figure 37-15 Gas Exchange in the Lungs Alveoli Section 37-3 Bronchiole Gas exchange occurs by diffusion across the membrane of an alveolus and a capillary. Capillary
