Cardiovasculatory and Respiratory Systems
The graduate analyzes the structure and function of the human cardiovascular and respiratory systems.
INTRODUCTION
For this task, you will use your knowledge of the respiratory and cardiovascular systems. You will write an explanation of the normal operation and function of the respiratory and cardiovascular systems.
REQUIREMENTS
C. Explain the normal function of the respiratory and cardiovascular system by doing the following:
1. Explain the basic process of the respiratory system from initial respiration through gas exchange. (1.5)
2. Explain the blood flow through the gross cardiac and peripheral structures, starting with the right atrium. (1.9)
D. Acknowledge sources, using in-text citations and references, for content that is quoted, paraphrased, or summarized.
NOTES********************
For task 1, one needs to describe the steps of blood flow through the heart, to the lungs to get oxygenate, back to the heart and out to the body again. Again, I encourage telling a story, perhaps of a red blood cell on this journey. One needs to name and state the location/function of each of the four heart chambers, four valves, and the large blood vessels that directly enter or directly leave the heart. One also needs to include the locations and functions of key structures in the respiratory tract that air encounters on its way to the alveoli in the lungs, where gas exchange occurs, and the path of the blood back to the heart. It helps tremendously to find a labeled image of the heart on the internet and tell your story in your own words based on that. This allows one to avoid accidentally copying too many phrases from the learning resource. For the respiratory side, Dr. Shane Cutler made a great podcast for the class. Once can write down the structures he lists. Then, like the image, create that part of the story in one’s own words because one is just starting with the structures listed in order.
