What are the similarities and differences between the circulatory and respiratory systems?
The circulatory system pumps blood and respiratory system is the exchange of gases( carbon dioxide and oxygen)
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.
