Trace path of oxygen and carbon dioxide as it passes through the respiratory system • Air enters nose and mouth • Air travels through pharynx and larynx. • Between these two is the epiglottis, a flap to control air going to the trachea (has cartilage rings to hold its shape). • Branches into two bronchi; branches even more into bronchioles.3
Trace path of oxygen and carbon dioxide as it passes through the respiratory system • At the end of the bronchioles are grapelike sacs called alveoli. • They are surrounded by capillaries to exchange O2 andCO2 with the blood. • The membrane around the lungs is called the pleura. • The muscle called the diaphragm controls the inhaling and exhaling.
Where does the oxygen enters? Nose (1) and mouth (2)
What is located at #11? alveoli
Respiratory System • In which two openings does air enter the respiratory system? • Nose and mouth • What is another name for the trachea? Where is it? • Windpipe and located below epiglottis
Respiratory System • The trachea branches into what two pipes as it enters the lungs? • Bronchi • What are the grapelike clusters at the end of the small tubes in the lungs? • alveoli
Which electron carriers are in the form WITH the electrons? • FAD+ NAD+ FADH2 NADH • FADH2 NADH
NAD+ comes from: • Niacin • Vitamin C • Cholesterol • Vitamin E • ANSWER: niacin
What is redox? • HINT AND WHAT IT REPRESENTS • Leo goes Ger • Loss of electrons = oxidation • Gain of Electrons = reduction
