Similarities of Respiratory and Circulatory System

# data[].attributes.body
Both the systems are concerned with transportation of oxygen in the body.

The respiratory system moves gases into and out of the blood.

When deoxygenated blood enters the heart and it is then transported via pulmonary veins to be oxygenated by the lungs.

Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Both systems involve oxygen for the body to work.

Both the systems are involved in removing waste products out of the tissues and eventually out of the body, that is, Carbon dioxide.

The Circulatory system is made up of blood vessels that carry blood away from and towards the heart. The heart is the central organ for pumping the blood throughout the body. It is made of strong cardiac muscles. Heart pumps liquid blood a tissue where it transports nutrients, gasses waste and etc. The Right Atrium receive deoxygenated blood from the whole body which is pumped into the Right Ventricle. That sends the blood to the lungs for oxygenation through Pulmonary Artery. After that it the blood travels through Pulmonary Veins and is received in the Left Atrium. That pumps into the Left Ventricle, then goes to our Aorta which is the source of many arteries that carries oxygenated blood to different parts of our body.
