Question
BIO 135: Basic Anatomy & Physiology Chapter 14: Respiratory System 8. Gas Transport (p. 347-348; Fig. 14.10) a. 97% of oxygen entering the capillaries in the lungs will be transported to tissue cells in the red blood cells. How is the last 2 -3% of bound oxygen carried to tissue cells? i. When oxygen binds to hemoglobin in the lungs, the hemoglobin changes shape and the name changes to This O₂- blood travels throughout the body supplying oxygen to our tissue cells. to ii. At the tissue cells, oxygen diffuses from concentration from the systemic capillaries into the ECF and then into the tissue cells. Now the blood in the system capillaries have (high or low) oxygen concentrations. This causes the hemoglobin the red blood cells to change shape again and its name changes from oxyhemoglobin to This O₂ -- to pick up more blood is now on its way to the oxygen. b. Approximately. % of CO₂ that enters the systemic capillaries from the tissue cells, will travel as a dissolved gas in the blood. About. % of CO₂ will travel attached to a portion of the hemoglobin molecule forming About % of CO₂ will travel as the ion to the lungs. Where does this ion come from? CO₂ + H₂O + H₂CO3 HCO3+H* -- notice this is a reversible reaction. Be sure to read this section of the chapter - more than once! i. Blood pH = C. 1. Is blood very acidic, slightly acidic, very basic, or slightly basic? 2. What happens to blood pH when there is a build up in CO₂? Why? How should the primary respiratory center respond to this change in blood pH? 3. Lung Cancer: (read Medical Focus - p. 351-352) i. More prevalent in: who but now there is an increase in ii. Explain what happens to the upper respiratory tract in a person who smokes? iii. Metastasis: iv. Treatment: 6
