INTERCOSTAL MUSCLES Inhalation and exhalation make up 1 breath Internal intercostal muscles External intercostal muscles Sternum Inhalation ? Also termed inspiration ? Diaphragm contracts and flattens. ? Internal intercostal muscles relaxes ? While the external intercostal muscles contract ? The rib cage moves up and out. ? Enlarging the thoracic cavity and decreases the air pressure within. ? Air from the surrounding enters the lungs Exhalation ? Also termed expiration ? Diaphragm relaxes and arch upwards. ? Internal intercostal muscles contracts ? While the external intercostal muscles relaxes ? The rib cage moves down and in. ? Air is forced out of the lungs Summary

Topic 6.5 Gas Exchange IB Objective Students will know that the lungs are actively ventilated to ensure that gas exchange can occur passively Distinguish between ventilation, gas exchange and cell respiration Explain the need for a ventilation system I. All Living Things Respire Why living things must respire (breathe): 1. Cellular Respiration ? controlled release of energy in the form of ATP from organic processes in the cell C6H12O6 + O2 ---> 6CO2 + 6H20 + ATP 2. Gas Exchange -- Exchange of gases (Oxygen, Carbon Dioxide) between an organism and it environments 3. Ventilation - process of "changing" or replacing gas (Oxygen, Carbon Dioxide) in a space (ex: lungs) II. Ventilation A. Single celled organisms can easily diffuse gas in and out of a cell

Chapter 9 notes Cellular Respiration: Harvesting Chemical Energy Concept 9.1 Metabolic pathways that release energy are called catabolic pathways - fermentation and cellular respiration _____________: partial degradation of sugars that occurs w/out the help of O2 ________: O2 is consumed as a reactant along w/ the sugar - more efficient Concept 9.1 Cellular respiration occurs in the _______________ Organic + O2 ? Carbon + H2O + Energy compounds dioxide C6H12O6 + 6O2 ? 6CO2 + 6H2O + Energy 1 glucose = -686 kcals Concept 9.1 ATP is the central molecule responsible for energy used by the cell The cell uses enzymes to transfer phosphate groups from ATP to other compounds (making them _________________) ATP ? ADP + phosphate Concept 9.1

Cellular Respiration Wednesday, March 06, 2013 5:23 PM ? Cellular Respiration Cellular respiration - an ATP-generating process that occurs within cells; energy is extracted from energy-rich glucose to form ATP from ADP and phosphate C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy Glucose + air = carbon dioxide + water + energy Aerobic respiration - cellular respiration in the presence of O2; divided into three components: glycolysis, the Krebs cycle, and oxidative phosphorylation ? Glycolysis Glycolysis - the decomposition (lysis) of glucose (glyco) to pyruvate (or pyruvic acid); nine intermediate products are formed and, of course, each one is catalyzed by an enzyme; in six of the steps, magnesium ions are cofactors that promote enzyme activity; summary of the steps:

By: Chlo? Durfee Sydney Modder Ramya Ramesh Megumi Sharma Chase Damis The Respiratory System Larynx (Voice Box) Connects pharynx to trachea Provides airway Prevents food from entering respiratory tract Produces sound Pharynx (throat) Provides passageway for respiratory and digestive tracts Tube like structure that connects nasal and oral cavities to larynx Coordinates breathing and swallowing while eating Larynx/Pharynx Larynx/Pharynx Epiglottis Blocks food and liquids from entering the trachea Spoon-like structure Epiglottis Lungs Pair of spongy, air-filled organs. Located on either side of thorax. Covered by thin tissue called pleura. Pull in oxygen and absorbs it into linings of lungs. Pushes oxygen into chambers of the heart so oxygen travels throughout the body.
