Molecules and the Body
These tiny particles make up all living and nonliving things.
What are molecules?
This system moves blood around the body.
What is the circulatory system?
The smallest unit of life that needs energy to function.
What is a cell?
When a patient has low oxygen in the blood, which system might have a problem?
What is the respiratory or circulatory system?
This molecule is used by cells to release energy.
What is glucose?
This system takes in oxygen from the air.
What is the respiratory system?
Cells use oxygen and glucose to release this.
What is energy?
If a patient’s digestive system isn’t working, this molecule might be missing from their blood
What is glucose?
This molecule from the air moves into the bloodstream through the lungs.
What is oxygen?
This system breaks down food into smaller molecules.
What is the digestive system?
This process happens inside cells to release energy.
What is cellular respiration?
A patient’s cells aren’t getting enough energy. These are the two possible causes.
What are not enough oxygen or not enough glucose?
This molecule is made when cells use glucose and oxygen to release energy.
What is carbon dioxide?
These are the tiny blood vessels where oxygen and glucose move into cells.
What are capillaries?
If cells don’t get enough oxygen, this happens to energy production.
What is it decreases or stops?
The oxygen and glucose levels are normal, but the patient’s cells still aren’t using them. What might be wrong?
What is a problem with the cells themselves (cell malfunction)?
When a person doesn’t have enough glucose or oxygen, this happens to their cells.
What is the cells can’t release enough energy?
When these body systems work together, they get oxygen and glucose to all cells.
What are the respiratory, circulatory, and digestive systems?
Name two molecules cells need and two molecules they produce during cellular respiration.
What are oxygen and glucose (need); carbon dioxide and water (produce)?
This kind of evidence helps scientists figure out which body system is not working properly.
What is medical evidence or data?
