Question

What are the similarities and differences between the circulatory and respiratory systems?

Answer 1

The circulatory system pumps blood and respiratory system is the exchange of gases( carbon dioxide and oxygen)

Explanation:

The difference between these two systems is: Circulatory system is only made up of the blood, heart, blood vessels, lymph nodes
Respiratory System: Is only made up of the nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli(air sacs, where the gas exchange occurs)
Unlike the respiratory system, circulatory system is a network of blood.
Circulatory system pumps blood around the body and the Respiratory system is to take oxygen in and expel carbon dioxide.

Similarities: When deoxygenated blood enters the heart and it is then transported via pulmonary veins to be oxygenated by the lungs.
Both systems involve oxygen for the body to work.
