OBJECTIVES: • Become familiar with mammalian anatomy by sketching different organ systems • Understand how different organ systems work together to carry out vital processes in the individual • Learn about the function of different organs and their roles in multiple systems Heart Humans rely on specialized internal FIGURE 98.1 Organs of different organ systems body organs that perform vital functions. Those organs and associated structures that perform similar functions are grouped Ribs together as organ systems. Different Lungs organ systems carry out unique functions. For example, the musculoskeletal system is Diaphragm responsible for movement, while the immune system is crucial for defense. Different organ systems may perform different functions but are linked to other systems in order to carry out vital processes in the individual. For example (Figure 9B.1), the circulatory system and respiratory system are interconnected because oxygen and carbon dioxide are transported in blood vessels from the lungs to the body and from the body back to the lungs, respectively, by pumping actions of the heart. Just like the organ systems interact and assist one another, individual organs and structures often play multiple roles for an organism because they also have vital functions for other organ systems. For example, blood vessels, a structure of the circulatory system, transport nutrients for the digestive system, deliver oxygen and remove carbon dioxide from body cells as part of the respiratory system, carry 7 Fulls antibodies and white blood cells for the immune system, and the blood itself is in turn filtered by the kidneys of the urinary system. In Figure 98.1 above, the ribs (and connected intercostal muscles) are important for ventilation of the lungs, but they are bony and muscular structures that are part of the musculoskeletal system. In lecture and lab, you have studied the individual organs (Table 9B.1), their roles within particular organ systems, and their location within the human body. in Lab 09-A you watched the dissection video of a fetal pig, and you should now be very familiar with the internal and external anatomy of a pig.

Draw all the structures of 3 different organ systems of your choice in a silhouette (pig outline) provided to you in the PDF file attached to in Question 1. You may also draw your own pig outline for your drawing. Use the information from Lab 09-A, your textbook, and your learned knowledge of the anatomy of a fetal pig (and humans) to complete these drawings. As you complete your drawings, be sure to: • Have a total of 3 drawings: A separate drawing for each of the 3 organ systems. • Labelall major organs and associated structures following the list provided to you in Table 98.1 above. • Draw each organ in your systems of accurate size, shape, and location on the silhouette. • Show how the different organs within and between systems are physically connected (this means draw and label appropriate vessels that may connect organs to each other). Question 1 Homework Draw your own or use the pig outline in the attached file to make 3 separate drawings of distinct organ systems, and I drawing of all the systems connected together. Put all your drawings in one PDF file or image and upload it here when finished. pigsilhouette.pdf (80KB) Browse your computer or drag and drop file here Max file size: 50MB Accepted file types: PDF, JPG, JPEG, PNG 0/20 File Limit Activity B: Interactions between organ systems 2. In this activity you will use your knowledge of organ physiology (function) to explain how your 3 organ systems are interconnected in the mammalian body. Question 2a Homework – Unanswered In a paragraph, explain the primary role of each of the organ systems you drew? Be sure to discuss all 3 organ systems separately. Unanswered Submit Question 26 Homework – Unanswered In a few sentences, explain how your 3 systems function together (how are they linked?) Unanswered Submit
