PPT-Lungs Gaseous Exchange Breathing

Learning objectives Must say what the job of the lungs is and name the main parts Should describe the special features the lungs have to do their job really well Could explain how the alveoli work. Essentials of Exercise Physiology. Respiration. External respiration:. . ventilation and exchange of gasses in the lungs (pulmonary function).. Internal respiration. : . ventilation and exchange of gasses in the tissues (pulmonary function).. “In with the good air, out with the bad air”. Samantha Dow, SPT. Improve ventilation and increase efficiency of breathing. Aid in movement and clearance of mucous / sputum from lungs and airways to prevent build and increased risk of infection. PowerPoint. ®. Lecture Slide Presentation by . Robert J. Sullivan. , Marist College. EXCHANGE OF GASES. RESPIRATORY SYSTEM. The human respiratory system allows one to obtain oxygen, eliminate carbon dioxide. . Oxygen is needed for _______________. Oxygen is needed for . cellular respiration.. What is the difference between breathing and gaseous exchange? . Discuss with a peer. 1 and . half minutes. After respiration the oxygen gas . Gaseous Exchange. General factors affecting ‘flow’. F = k * . Δ. P / R. K = constant. Δ. P = delta P, ‘pressure gradient’. R = ‘resistance’ . For exchange of respiratory gases in lungs…. Breathing. Ch. . 15.2 Mechanism of Breathing . pp. . . 288 . to . 291. What does respiration mean?. Respiration refers to the . entire. process of getting . O. 2. to the body cells and ridding the body of . Function of Respiration. SBI 3U1. What is the function of the . Respiratory System?. To that ensure that . oxygen. is brought in and . carbon dioxide. is removed from each cell in the body…. . The 4 stages of Respiration:. The Layout of the . R. espiratory Organs. Breathing. Before Exercise. After intense exercise. Breathing is regular. Breaths have less volume. Enough oxygen is being provided to the muscles. Breathing is frantic. Inhalation. Nasal cavity. Hairs: filter air. Mucus: filters & moistens. Blood vessels: warm air. • . Pharnyx. (throat). • Larynx (voice box)- glottis, epiglottis. • Trachea (wind pipe)- mucus & hairs.. Breathing(External respiration) . The . process of exchange of O2 from the atmosphere with CO2 produced by the cells.. Respiratory Organs . • Direct respiration by diffusion from the environment – sponges, coelenterates, flat worms etc.. Do Now activity:. Identify some of the organs involved in the gas exchange system in the human body.. Discuss with your partner what function of some of these organs might be within this system. Explain why organisms need an efficient gas-exchange system. Lungs are the organs of respiration. . What is. gas exchange. ?. The right lung is a little bigger than the left lung. This the left lung has to fit around the heart making it slightly smaller.. The lungs are split into lobes. 1. Pulmonary ventilation. = exchange of gases between lungs and atmosphere.. 2. External respiration. = exchange of gases between alveoli and pulmonary capillaries.. 3. Internal respiration. = exchange of gases between systemic capillaries and tissue cells.. Breathing(External respiration) . The . process of exchange of O2 from the atmosphere with CO2 produced by the cells.. Respiratory Organs . • Direct respiration by diffusion from the environment – sponges, coelenterates, flat worms etc..
