How are the respiratory and the digestive systems similar?

Answer 1

The cardiovascular system consists of the heart, veins and arteries. Which are all part of the network which moves blood around your body.

Your respiratory system is your lungs and airways. This system is responsible for gas exchange (taking in oxygen and expelling CO2).

They work hand in hand, your respiratory system takes in oxygen and passes it into your cardiovascular system, which transports it to all of your muscles and organs. The muscles and organs pass back CO2 which is then expelled through your respiratory system.

Answer 2
