SVHS Advanced Biology Name: Period 1 2 3 4 5 6 THE RESPIRATORY SYSTEM A picture of lung tissue magnified several hundred times. The small numerous structures are the alveoli. These small sac-like structures are the location where all gas exchange takes place between the blood of the pulmonary circulation and the air that we inhale. The larger structure to the right is a bronchiole which carries air to the alveoli.

Label the parts of the model with the names of the structure that is represented. To the side of the diagram explain what structures of the human respiratory system are not represented by the model. In a second paragraph, explain why the balloons inflate when the rubber sheet is gently pulled down and why they deflate when the rubber sheet is allowed to return to the original position. Be sure to mention air pressures and changes in the pressures. Bell Jar Model of Mechanics of Breathing PART C: In the space below diagram 2-3 alveoli using the microscope prepared slides of human lung tissue. Label the alveoli. Diagram a blood vessel and a bronchiole tube that you observe next to the alveoli. Label all structures. Beside the diagram explain what occurs in the alveoli during external respiration. Human Lung Tissue (100X) Diagram a section of this lung tissue that shows the cancerous tissue as it lies next to normal lung tissue. Label, using brackets and arrows, normal and cancerous tissue. What kinds of cells become cancerous? Explain. Metastatic Carcinoma of Lung (100X) normal tissue: Diagram the lung tissue that shows a distinct difference compared to normal lung tissue. Explain how emphysema tissue is different compared to normal tissue. How does this difference result in people not being able to walk up a flight of stairs? Pulmonary Emphysema (100X) Label Structures Observed and explain briefly how each slide differs from normal tissue. (internet search) How does hyaline membrane disease affect prematurely born infants? Hyaline Membrane Disease (100X) PART D: Below is a sample Spirogram. A machine monitors a person’s breathing. Each upward movement of the line represents inhalation and each downward movement of the line represents exhalation. The volume of air moved is recorded and can be read from the spirogram. The rate at which a person is breathing can also be read from the spirogram. Fill in the values in the column titled “Value from Spirogram” by reading the spirogram. The second column is for your measurements as measured by the instruments in class. ---------------------------------------------------------------------------------6000 ---------------------------------------------------------------------------------5000 ---------------------------------------------------------------------------------4000 ---------------------------------------------------------------------------------3000 ---------------------------------------------------------------------------------2000 ---------------------------------------------------------------------------------1000 - ml ml ml ml ml ml Time Lung Volume Tidal Volume Vital Capacity Expiratory Reserve Expiratory Capacity Inspiratory Reserve Inspiratory Capacity Total Lung Volume Residual Volume Value from Spirogram Your Measured Value PART E: A) Choose one of the “if... then” statements below to study.
