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)?
Where can we find good bacteria?
Digestive system or intestine
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?
Chicken pox, Covid -19, HIV are all considered _________
Virusus
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. They are considered NOT alive.
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?
What type of infectious agents cause strep throat, food poisoning and ear infections?
Bacteria
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?
Good bacteria are used to make food we eat such as ________
Yogurt or Cheese
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. They are considered alive.
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?
the brain, heart, lungs, immune system, and nervous system
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?
