Do all cells perform cellular respiration?
YEAH! Every living thing needs energy. Check your characteristics of life worksheet in your notebook :]
What is the function of the circulatory system
To pump blood throughout the body because blood carries our nutrients that our cells need
Name 3 different type of cells
Hair, blood, eyes, skin, etc.
Chemical Reaction
process of changing molecules
Glucose and oxygen are needed for cellular respiration. How do you get those molecules?
Glucose - eating food (starch/fat)
Oxygen - breathing
BONUS POINTS - Mentions that you get oxygen from plants (photosynthesis)
Why do our organ systems work together?
Our systems work together to ensure that our body remains at homeostasis and keeps us healthy
process of producing energy in the body
Why do our cells perform cellular respiration?
Because your body needs ENERGY for ALL life processes
Give one example of two organ systems working together.
Respiratory gives oxygen to circulatory so it can give it to the cells
Digestive gives nutrients to circulatory so it can give it to the cells
