Explanation:

( Respiratory Tract)

1. The body cells need a continuous supply of oxygen for the metabolic processes that are necessary to maintain life. The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood.

2.Your respiratory system brings oxygen into your body and helps to remove carbon dioxide. Problems with your respiratory system can reduce the oxygen that reaches your lungs, which can make you unwell.

( Circulatory Tract)

1. The circulatory system is your heart and blood vessels, and it's essential to keeping your body functioning. This finely tuned system carries oxygen, nutrients, electrolytes, and hormones throughout your body.

2. All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body.
