Muscular System
Why does your heart rate increase when you do exercise?
Because your body requires more oxygen which is in the blood, so your heart needs to pump blood faster around the body so you can do exercise
Because your body requires more carbon dioxide in the muscles to exercise
Because your body requires oxygen from your respiratory system which will move blood around your body
Because you are unfit
How does the respiratory system and circulatory system work together to allow someone to exercise?
Carbon dioxide is inhaled and travels through the blood in the circulatory system to give the body energy to exercise
Food is digested in the digestive system and gives the body energy to exercise
Oxygen is inhaled and the faster someone breathes, the more glucose they get to give them energy to exercise
Oxygen is inhaled and travels through the respiratory system and then enters the circulatory system through the blood and is moved around the body to the muscles
If a person's heart rate is increasing because they are running laps, what do you think would happen to their respiratory rate (how fast they breathe)?

It will get faster (increase)
It will stay the same as if they were not running

If the small intestine was damaged and the villi inside was harmed, what do you think will happen to the percentage of absorption of nutrients?
It will increase and more nutrients will be absorbed
It will not change how many nutrients are absorbed
It will decrease and less nutrients will be absorbed
The small intestine has a large surface area which helps with absorption, but it also has a long _________
