Question

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.

Answer 1

Homeostasis is the body's ability to maintain a constant and healthy internal environment via negative and positive feedback. Buffers are substances that maintain pH balance, which is crucial for homeostasis. The skin contributes to homeostasis by regulating temperature and providing protective barriers.

Step-by-step explanation:

Homeostasis is the maintenance of a stable internal environment within the body. It is crucial for the well-being of cells and for the overall function of organ systems. The body uses both negative and positive feedback mechanisms to maintain a state of equilibrium. Negative feedback mechanisms involve responses that counteract a change to keep things at a set point, like insulin reducing high blood glucose levels. In contrast, positive feedback mechanisms amplify responses, such as the increase of contractions during childbirth due to the hormone oxytocin.

A buffer is a chemical substance that helps maintain the pH balance by reacting with acids or bases to minimize their effects on the pH of a solution. This is critical for chemical homeostasis in the body. If a patient were given sterile water instead of saline, they would receive a hypotonic solution. The tonicity of the solution is lower than that of the red blood cells, leading to water influx and potential cell lysis, disrupting homeostasis.

The skin plays a significant role in maintaining tissue and organ homeostasis. It regulates body temperature through sweat and provides a protective barrier from pathogens. The presence of skin-associated lymphoid tissue (SALT) and the synthesis of Vitamin D are specific examples of how skin contributes to homeostasis.
