To move oxygen through the body to the cells and to move the waste away from the cells.

What is the purpose of the digestive system?
To break down food so that the nutrients and glucose can be small enough to be used by cells
100
What gas that is breathed in is absorbed in the blood in the lungs?
Oxygen
100
What is a cell?
The basic structure of life that preforms all basic life functions.
100
Digestive System: What happens during ingestion?
The food enters the body
200
Why is oxygen so important to the circulatory system?
Cells need the oxygen that is moved by the blood for cellular respiration.
200
What are the stages of your digestive system?
Ingestion, Digestion, Absorption, and Elimination
200
What gas is released out of the blood into the lungs?
Carbon Dioxide
200
What is a tissue?
a group of the same type of cells doing the same job
200
Digestive System: What happens during absorption?
Nutrients from your food enters the blood
300
What is the heart's purpose?
To pump blood throughout the body
300
What are the two different types of digestion?
Mechanical and Chemical

Explain what happens to air when you breathe.
It enters the mouth or the nose, it travels down the trachea, into the bronchi, then to the lungs and into the alveoli where the oxygen enters the blood
300
What is an organ system?
A group of organs working together
300
How is the digestive system connected to the circulatory system?
it breaks down the food small enough to enter the blood so that is can be carried to the cells of the body
400
Where does blood with oxygen in is travel to when it leaves the heart?
To the cells of the body
400
What is the job of the stomach?
Mixing of food and breaking down with enzymes and acids
400
What is the job of your mouth and nose in the respiratory system?
To warm the air before it enters the lungs
400
What is an organ?
Different types of tissues that are working together for a complex function
400
How is the respiratory system connected to the circulatory system?
it takes in the oxygen that is absorbed by the blood and carried to the cells in the body
500
Where does deoxygenated blood travel to when it leaves the heart?
To the lungs
500
What is the job of the small intestines?
Absorb nutrients from the food into the blood
500
Where in your lungs does oxygen enter and carbon dioxide exit?
Where the capillaries meet the alveoli

List the four levels of the organization of life in order from least complex to most complex.
Cells, Tissues, Organs, Organ Systems

How are all three systems connected to the process of cellular respiration?
The digestive system breaks down food for glucose, the respiratory system brings in oxygen and the circulatory system carries the glucose and oxygen to the cells for cellular respiration
