Bell Work: 3/18/15 Anita sprinted around the track at her school. At the end of her run, she was taking more air into her lungs and her heart rate had increased. What systems regulate Anita’s breathing rate and heart rate? A.Muscular and skeletal B.Nervous and endocrine C.Digestive and excretory D.Respiratory and circulatory Human organ systems work together in many ways. Which statement accurately explains the relationship between two body systems? A.The excretory system regulates the temperature of the integumentary system. B.The skeletal system delivers nutrients absorbed by the endocrine system. C.The digestive system delivers oxygen absorbed by the respiratory system. D.The nervous system regulates the movement of the muscular system.

Standards SPI 0707.T/E.3 Distinguish between the intended benefits and the unintended consequences of a new technology. SPI 0707.T/E.4 Differentiate between adaptive and assistive bioengineered products. SPI Explain the basic functions of a major organ system. What are the intended benefits and the unintended consequences of the new technology? Are we able to differentiate between adaptive and assistive bioengineered products? What is the basic function of the skeletal and muscular systems? How do they work together for survival? Essential Questions

Biomedical engineers use their knowledge of the human body to design technologies to solve problems related to biology, health, and medicine. Biomedical engineers collect and analyze data about the human body to help inform the design of various technologies, such as prosthetics and pacemakers. In this challenge, you and your team will take on the role of a biomedical engineer as you collect data for an athletic shoe company, design and create knee braces for an injured knee, and design and create biomechanical equipment for a specific sport. Your team will focus on the muscular and skeletal systems (i.e. musculoskeletal system) and how they interact with one another. Your knee brace must support a model injured knee to enable it to move like a healthy knee, while at the same time being cost- effective. The biomechanical equipment for a specialized sport must either enhance performance or prevent injury, while also being cost-effective.

Restate your problem State what you already know List any limitations or controls

Research the following topics: Biomedical engineering or bioengineering Biomechanics External parts of the foot Muscular and skeletal systems—specifically how they interact with one another Muscular and skeletal systems—specifically how they interact with one another Internal parts of the knee Action research on foot shapes, sizes, and arch heights Knee braces Knee braces Your selected sport & biomechanical equipment Brainstorm ideas with your team for each problem.

Knee Brace Presentations You will be scored on the following: 1. Range of Motion 2. Usability 3. Durability 4. Presentation

Pick an Olympic sport (winter or summer) and design either a piece of equipment that will enhance the sport or help to prevent injury. You must research the Olympic sport in depth, including equipment used and common injuries related to the sport.
