Contextualization

Life on our planet is incredibly complex and diverse, ranging from simple unicellular microorganisms to complex multicellular creatures, like us humans. But have you ever stopped to think about how all the parts of our body work together to keep us alive and functioning? In this context, "Organization of Systems" refers to how the different parts of an organism work together, organized into systems, to create a functional and healthy organism.

In the case of humans and other animals, these systems include the respiratory system, the circulatory system, the nervous system, among others. Each of these systems has a specific role and is composed of various organs and tissues that work together. For example, the circulatory system is responsible for transporting blood (and the nutrients it carries) throughout the body, while the respiratory system allows us to inhale oxygen and exhale carbon dioxide.

This organization into systems is one of the characteristics that allows us to live and carry out our daily activities. For instance, when you run, your respiratory system works harder to supply oxygen to your muscles, while your circulatory system speeds up the blood flow to transport this oxygen to where it is needed. But what would happen if one of these systems was not functioning properly?

Importance of Organizing Systems

Understanding the organization of systems allows us to better understand how our bodies function and how we can keep them healthy. Furthermore, it is crucial for healthcare professionals, such as doctors and nurses, to understand the organization of systems so they can diagnose and treat various diseases and medical conditions effectively.

For example, if a doctor understands how the circulatory system works, they can more easily identify problems like heart diseases or hypertension. Similarly, a good understanding of the respiratory system can help treat conditions like asthma or chronic obstructive pulmonary disease (COPD).

Moreover, understanding the organization of systems also has applications in engineering, particularly in biomedical engineering. Biomedical engineers use their knowledge of the organization of systems to design and create medical devices, such as pacemakers or prostheses.

Activity

Activity Title: Modeling Human Body Systems

Project Objective:

The objective of this project is to allow students to gain a better understanding of the different systems of the human body, how they are organized, and how they interact to keep the body functioning in a healthy manner.

Detailed Project Description:

Students will be divided into groups of 3 to 5 people. Each group will be responsible for creating a 3D model of a specific system of the human body (for example, circulatory system, respiratory system, nervous system, etc.). The students should research their assigned system, understand its different components, how each component contributes to the system as a whole, and how the system contributes to the overall functioning of the human body.

After creating the models, each group will present their system to the class, explaining its functions and importance for the human body. The project will culminate in a written report, where students will describe their research, the model construction process, and what they learned about the organization and interaction of systems in the human body.

Required Materials:

• Materials for building the models (e.g., clay, papier-mâché, plastic, etc.)
• Research materials (books, internet access, etc.)
• Documentation materials (paper and pen, or computer)
• Camera to document the process (optional)

Detailed Step-by-Step Guide for the Activity:

1. Research and Preparation (1 hour): Each group should research the assigned system. They should identify and understand the main components of the system, how these components interact with each other and with the rest of the body, and how the system contributes to the overall functioning of the body.

2. Model Planning (30 minutes): The groups should decide how they will represent their system in a 3D model. They should consider accuracy and scale, as well as the practicality and availability of materials.

3. Model Construction (2 hours): The groups should work together to build their model. They should ensure that all the main components of the system are represented and that the model is clear and understandable.

4. Presentation Preparation (30 minutes): Each group should prepare a brief presentation explaining their model, the components of the system they represented, and how these components interact to form the complete system.

5. Presentation (1 hour): Each group should present their model and findings to the class.

6. Report Writing (2 hours): After completing the practical activity, each group should work on their report detailing the process they went through, their findings, and their conclusions.

Project Deliverables:

Students should deliver two main products: the 3D model of the human body system and a detailed written report.

The 3D model should be a clear and accurate physical representation of the assigned human body system. It should show all the main components of the system and, if possible, how these components interact with each other and with the rest of the body.

The written report should be presented in the format of a formal report and should include:

1. Introduction: The student should contextualize the topic, its relevance and real-world application, as well as the objective of this project.
2. Development: The report should detail the research conducted by the students, the process of building the model, and their findings about the human body system they studied.
3. Conclusion: The students should conclude the work by summarizing their main points, explaining the learnings obtained, and the conclusions drawn from the project.
4. Bibliography: The report should include all sources consulted during the research.

Writing the report should not be seen as an individual task, but should be a collaboration of the whole group, sharing and discussing ideas and findings. This way, the project offers the opportunity to practice important socio-emotional skills, such as time management, communication, problem-solving, creative thinking, and proactivity.
