Activity 7 – Connecting Concepts
Review topics: Homeostasis, Acids and Bases, the Cell Membrane, and Functions of the Integumentary System in Unit 1 Learning Content to respond to the following 1-2 well-composed paragraphs written in your own words. If any outside sources are used to inspire and support your response, please properly cite and reference them in APA format.
At the beginning of this unit we discussed the idea that our systems function on many levels – organs, tissues, cells, and chemicals working together to fulfill their purpose. When everything works correctly, we are in a state of homeostasis. In this task, you’ll share your understanding of homeostasis and provide examples of how the body works to maintain homeostasis.
Part One:
• Briefly compare and contrast negative and positive feedback in your own words – make sure you discuss both similarities and differences.
Part Two:
• Chemical Homeostasis: Define what a buffer is and briefly describe how it interacts with chemical substances to maintain the balance of pH needed by the body to function.
• Cellular Homeostasis: Saline is an isotonic solution; however, if a patient was accidentally hydrated with sterile water instead of saline:
o Describe the tonicity/osmolarity of the water and the relative tonicity/osmolarity of the patient’s red blood cells.
o What will happen to the patient’s red blood cells over time as they attempt to reach equilibrium? Are the cells maintaining homeostasis as they undergo this process – justify your answer.
• Tissue/Organ Homeostasis:
o Describe 2 roles of the skin in homeostasis making sure to include how a specific organ, tissue, cell, or chemical related to the skin helps the body maintain the proper conditions to function.
