BIO202L Lab 13 The Respiratory System Updated Examination Study Guide 2022/23 Pre-Lab Questions 1. Name two functions of the nasal cavity mucosa. Moistens, warms, and filters air passing through nasal cavity 2. Why is the trachea reinforced with cartilaginous rings? It helps to avoid collapse during pressure changes occurring from breathing, which prevents airway blockage. 3. Describe the path a molecule of oxygen takes to get to body tissue, starting with the nares. Nares --> pharynx --> trachea --> bronchi --> bronchioles --> aveoli --> left ventricle --> aorta --> artery --> arteriole --> capillaries at which point diffusion occurs 4. What is asthma? A condition in which a person’s airways become inflamed, they start to narrow and swell, and produce extra mucus. This in turn makes it difficult for a person with asthma to breathe. A person who has asthma experiences a constriction of their bronchial tubes that will not allow air to pass into smaller tubes. Experiment 1: Microscopic Anatomy of the Respiratory System Table 1: Experimental Observations Respiratory Image Description of Visible Structure(s) Trachea - goblet cell - cilia - basement membrane - columnar cells - connective tissue of lamina propria Lung - bronchi -capillaries - alveoli - bronchiole - simple squamous epithelium - alveolar sac Post-Lab Questions 1. Label the arrows in the slide images below. A- Golblet Cell BIO202L Lab 13 The Respiratory System Updated Examination Study Guide 2022/23 B- Basement Membrane C- Connective tissue of lamina propria D- Cilia E- blood vessel F- Bronchi G- Alveolar sac H- Alveoli BIO202L Lab 13 The Respiratory System Updated Examination Study Guide 2022/23 Post-Lab Questions 1. How many diaphragm(s) exist in the human body? one 2. Does deoxygenated blood become oxygenated in the upper respiratory tract, the lungs, or the diaphragm? lungs 3. Is the trachea superior or inferior to the diaphragm? superior 4. Which component is more medial: the right lung or the tracheal bifurcation? Tracheal bifurcation 5. What is the most inferiorly located organ of the respiratory system? the diaphragm Experiment 3: Understanding Lung Mechanics Table 2: Understanding Lung Mechanics Observations Squeezed Bottle Observations (Step 3) Released Bottle Observations (Step 4) The balloon inflated upon squeezing the bottle, and the bottle lost air capacity as well. The balloon deflated to a smaller size upon releasing the bottle. BIO202L Lab 13 The Respiratory System Updated Examination Study Guide 2022/23 Post-Lab Questions BIO202L Lab 13 The Respiratory System Updated Examination Study Guide 2022/23 1. What happens to the balloon? Why? the balloon inflates and deflates depending on oxygen being released or pushed into the balloon. 2. What would happen if the seal at the base of the bottle leaked? Air would slowly leak out and have a harder time filling the balloon 3. What causes a collapsed lung? A collapsed lung can be caused by an injury to the lung, or in some cases it can be caused by air blisters which are also known as blebs that break open and send air into the space around the lungs. 4. Is a collapsed lung functional? Why or why not? A collapsed lung will not allow your lung to function at full capacity. The lung would not be able to fill up with air, nor filter out oxygen. Experiment 4: Spirometry Patient A Table 1: Patient A Spirometry Data Predicted Values Resting Value Exercise Value FVC 4.93-5.91 5.319 5.021 FEV1 4.88 4.63 4.02 FEV1/FVC 83.3% 87% 80.2% Observations of spirometry graph shapes: Click here to enter text.

BIO202L Lab 13 The Respiratory System Updated Examination Study Guide 2022/23 4. Based on the results of the spirometry test, what do you think is the cause of Patient D’s respiratory symptoms? Explain your answer using the data collected during the test. Conduct your own external research if necessary. Click here to enter text. 5. Based on the results of the spirometry test, is Patient E suffering from asthma? Explain your answer using the data collected during the test. Click here to enter text. 6. What are some potential drawbacks to relying on spirometry to diagnose respiratory conditions? Conduct your own external research if necessary. Click here to enter text. Experiment 5: Fetal Pig Dissection: The Respiratory System Post-Lab Questions 1. Describe the interior lining of the trachea. The lining is ciliated columner 2. Were there many or few vessels serving as conduits between the lungs and the heart? Why is this important? There were many vessels due to the lungs and heart needing a certain amount of blood that’s oxygenated at any time. 3. Describe the function of the diaphragm during inhalation and exhalation. During inhalation the diaphragm contracts. This causes the thoracaic cavity to enlarge. When we breathe out the internal intercoastal muscle relaxes.
