Possible misconceptions from this unit over the human body systems and diseases are:
- The body systems operate in isolation from each other.
Students typically have a hard time understanding how the body systems function together to fight off disease. Because the body systems are typically studied in isolation from each other, it is critical to go over how the body systems work together.
- When we are not using a certain part of our body, functions of the organs/system stop.
This idea is probably one of the causes students have misconceptions on the body systems operating in isolation from each other. Students need to know that the body systems are at constant work at all times and any changes to a system can have affects on other systems.
- Viruses and bacteria are the same (living) organisms.
Many people do not understand the difference between viruses and bacteria because both viruses and bacteria are very tiny and can cause diseases. Students need to understand the main differences between viruses and bacteria in order to understand how transmission, symptoms, and treatments are possible with each disease.
