Body Systems
This system breaks down food into nutrients the body can use.
What is the digestive system?
his infectious agent can be prevented through vaccinations, while antibiotics are effective for treating this other type.
What are viruses (prevented by vaccination) and bacteria (treated by antibiotics)?
This is the term for all factors in an experiment that are kept the same except for the one being tested.
What are controlled variables (or constants)?
This is the smallest unit of matter that makes up everything around us.
What is an atom?
This system defends the body against infections and foreign substances.
What is the immune system?
This system supplies oxygen to the blood and removes carbon dioxide.
What is the respiratory system?
Some types of this infectious agent can be transmitted through mosquito bites, like the malaria-causing Plasmodium.
What is a parasite?
cientists do this when they use data and evidence to explain why their hypothesis was correct or incorrect.
What is defend a conclusion?
Atoms combine to form these, which are groups of two or more atoms held together by chemical bonds.
What are molecules?
This system is composed of muscles and bones that support movement and structure.
What is the musculoskeletal system?
Known for pumping blood throughout the body, this system includes the heart and blood vessels.
What is the circulatory system?
These infectious agents are much smaller than bacteria and cannot be treated with antibiotics.
What are viruses?
This is the factor in an experiment that is measured to see if it changes in response to the independent variable.
What is the dependent variable?
These are the basic building blocks of life, making up all living organisms.
What are cells?
The system that allows humans to create offspring, ensuring the continuation of the species.
What is the reproductive system?
This system removes waste products from the blood and helps regulate fluid balance.
What is the excretory system?
This type of infectious agent can cause ringworm and thrives in warm, moist environments.
What is a fungus?
This is the type of data that is typically represented in charts, tables, or graphs.
What is quantitative data?
A group of similar cells that perform a specific function together forms this.
What is tissue?
This system works closely with the respiratory system to deliver oxygen to body cells and remove carbon dioxide.
What is the circulatory system?
This body system is responsible for detecting and responding to internal and external changes.
What is the nervous system?
Unlike viruses, these infectious agents can reproduce on their own and do not need a host cell.
What are bacteria?
In an experiment, this is the factor that the scientist changes on purpose to observe the effects.
What is the independent variable?
These are structures composed of different types of tissues working together to perform a specific job in the body.
What are organs?
When you exercise, your circulatory and respiratory systems work together to increase oxygen delivery to muscles. These waste products are removed by the excretory system to maintain this balance in the body.
What is homeostasis?
