You are tasked with making sure a diver is safe and healthy during a two-hour dive. What should you observe?
how much food and air molecules the diver gets
how much food is digested while he is diving
how much sleep the diver gets
how many different types of foods the diver gets
How does air go through the body. (label first step to last step)
The alveoli transport the oxygen to the blood
The nose and mouth take in oxygen and send it to the lungs
The blood brings oxygen to the cell
The cell takes in the oxygen and uses it to produce energy
Would it be hard to exercise if your digestive system wasn't working? Why or why not?
yes, because food wouldn't be broken down
no, you'd just breathe in more air
Yes, your cells would remain empty
Yes, you wouldn't be able to sleep
Your digestive system results are in: starch is high, oxygen is none and glucose is low. Can you exercise?
Yes, the body is functioning
No, the digestive system is putting together oxygen and glucose
Yes, you need to breathe in more air
No, the digestive system isn't breaking down food
You believe that the human body works best if it gets molecules from food and air. Are you correct?
No, the body works when lungs get air and the stomach gets food
No, the cells make all the molecules we need
No, the body needs molecules from different foods
Yes, the body works best with molecules from food and air
Your respiratory system stops working. Can you exercise?
No, the molecules from air are too large for the cell
No, the respiratory system wouldn't break down oxygen
No, your cells can't work without oxygen
Yes, the digestive system will work twice as hard
How do food molecules travel through the body. (List the steps from beginning to end)
Amino acids and glucose enter the blood stream
The blood brings the molecules to the cell where its used to produce energy
The stomach breaks down starches into glucose and proteins into amino acids
Food enters the body through the mouth and goes to the stomach
Your friend has asthma. Why can't he exercise?
he isn't getting enough sleep
he would need more molecules from air
his cells don't have all molecules, but he can exercise
he isn't getting different types of food molecules
Which system contains the mouth, wind pipe (trachea) and lungs?
circulatory
cells
digestive
respiratory
What is the respiratory system responsible for?
breaking down proteins and starch into amino acids and glucose
storing glucose
pumping blood around the body and bringing molecules to cells
taking in oxygen and releasing carbon dioxide
Which system contains the heart and all blood vessels?
respiratory
cells
digestive
circulatory
What is the circulatory system responsible for?
breaking down proteins and starch into amino acids and glucose
pumping blood around the body and bringing molecules to cells
storing glucose
taking in oxygen and releasing carbon dioxide
Which system contains the mouth, esophagus, stomach, small intestine and large intestine?
digestive
respiratory
cells
circulatory
What is the digestive system responsible for?
taking in oxygen and releasing carbon dioxide
