Organ systems.
Blood flows through veins to carry ________ to cells and carbon dioxide away from cells.
Oxygen
Explain why the respiratory system is important.
It brings in oxygen for our body cells, and releases carbon dioxide (waste).
These are the two different types of cells.

Organs are made up of ________.
Tissues.
What are the different parts of blood?
Red blood cells, white blood cells, plasma, and platelets.
Name at least 3 parts of the respiratory system.
Mouth/nose, trachea (windpipe), lungs, bronchi, broncholues, alveoli, capillaries
Cells are made of __________ ___________ parts.
Many different
Anton van Leeuwenboek and Robert Hooke did what?
They discovered living and dead cells.
Put these in order: Organism, tissue, cell, organ system, organs.
Cell, tissue, organ, organ. organ system, organism.
Explain how the circulatory system works.
The heart contracts (squeezes together) to pump blood from the left side of the heart through the body. Blood travels around the body, delivering oxygen and picking up carbon dioxide. It travels to the right side of the heart, where it is pumped to the lungs to drop off carbon dioxide and pick up oxygen. It then is returned to the left side of the heart to start the process again.
Explain the gas exchange process.
We breathe in oxygen. It travels through the mouth/nose, trachea, bronchi, and to the alveoli. Here, the oxygen diffuses into the blood through the capillaries, and carbon dioxide diffuses into the alveoli from the blood. We then breathe out the carbon dioxide in reverse order.
