Drawing Assignment - Respiratory System APII, Lisa Tracy Assignment Rationale To help you develop an understanding of the structure and function of four organ systems you will produce a drawing (diagram) that includes information about each system's structures and functions. This assignment is designed to encourage you to organize the material using a learning technique that differs from completing a table or flow chart. Full credit will not be given unless a drawing/diagram is completed and turned in on time. Remember your drawings do not have to be a work of art...just the basic outlines of the systems/structures etc. are required. Use only one side of one 8 X11 piece of paper. The work of keeping it brief is that you are determining the most important structures and creating a study tool. Assignment Overview The respiratory, urinary, digestive and reproductive systems all require and understanding of the movement of 'something' from one point to another (i.e. Point A to point B). For example, inspired air moves from the external nares through a series of conducting structures and, finally, deep within the lung into the final microscopic structures where gas exchange occurs. By tracing the movement of 'something' such as an oxygen molecule you will develop an understanding of the anatomy and physiology of each structure it moves through along its route. The additional information (epithelium, characteristics and functions) can be located anywhere on the diagram...while some students prefer to write it next to the structure others use a key method. For example, label the external nares #1 and then write stratified squamous, divided by the nasal septum, allows passage of air into the respiratory system, somewhere else on the paper. Remember you are creating a study guide for your own use so it is up to you to decide what works best for you. I provide you with reference drawings, but you are not meant to draw each of them. Doing so could actually hurt your grade if I cannot follow where the molecule is moving. Only original, hand drawn diagrams will be graded. Copies of drawings will not be accepted and, if you work with someone, you must each create your own unique diagram. You may type up labels and attach them to the diagram if you prefer. Please make certain your work is legible and neat so it is easy to grade. Due to the fast pace of the course, I will not usually be able to return diagrams to you before you need them to study for an exam. So, please make a copy or take a picture of your work to study from. OR, keep the original and turn in a scan or even a picture from your phone into the open assignment submission folder. Respiratory System Instructions Draw the respiratory diagram as though you are tracing a single oxygen molecule as it enters the external nares through all the conducting zone structures, the respiratory zone structures and, finally into a RBC located within an alveolar capillary (this means you must include a cross sectional drawing of the respiratory membrane, see figure 23.8). Information that should be included in your drawing Epithelium associated with each structure Characteristics (general and distinctive) such as size, location, etc. Function(s) Note: you are only tracing one inspired oxygen molecule so you do not have to trace it into both left and right structure as the molecule cannot be in two places at once. Grading Rubric for Drawings: 5 points: I can easily trace the corn kernel, oxygen molecule, creatinine molecule, or sperm from its origin to endpoint. All structures are named. Most structures have brief information about function, characteristics, and epithelium type. 4 points: Missing information about one of the following: function, characteristics, or epithelium. 3 points: Missing information about two of the following: function, characteristics, or epithelium. 2 points: I cannot easily trace the molecule from its origin to endpoint. Diagrams are a series of disjointed drawings of each structure, rather than a summary of movement between structures. OR many structures are missing or out of order. OR there is no information about function, characteristics or epithelium for structures. 0 points: Incomplete, inaccurate, messy attempt
