The primary functions of the heart and longs are:
Lungs:
- Oxygenate the blood
- Remove carbon dioxide from the blood
Heart:
Circulate blood in the body, so that cells receive oxygenated blood.
Circulate blood in the body, so that de-oxygenated blood is once again oxygenated and carbon dioxide removed.
To the lungs
heart lungs and skin
The heart is responsible for circulating blood through the body, and the lungs are responsible for oxygenating it. Both are needed to get the much needed oxygen to the cells of the body.
the heart does not give the body it's oxygen it is the lungs. The heart is used to pump the blood to the lungs to pick up oxygen and then to pump the blood throughout the body and add oxygen to the blood cells.
Oxygen is taken into the body through the respiratory system when we breathe in air into our lungs. The respiratory system includes the nose, mouth, trachea, bronchi, and lungs, where the oxygen is absorbed into the bloodstream and carried to all the cells in the body.
The red blood cells carry the oxygen from the lungs round the body. The heart pumps the red blood cells to go around the body. When the oxygen is given to the cells, the red blood cells return to the heart and get pumped back to the lungs while carrying carbon dioxide.
These serve in transporting blood between heart, organs, and muscles. Arteries usually leave the heart and transports blood to the body(systematic circulation) or to the lungs(pulmonary circulation).
To get rid of the carbon dioxide produced in the cells of your body, and to get new oxygen to transport to your cells.
The heart pumps blood all around your body and it picks up oxygen from the lungs to send to numerous cells throughout your body. The oxygen is carried in your blood by red blood cells.
Our Body Cells go to our lungs, and then our heart to help us breath.Other Body Cells takes out Carbon Dioxide. ( If you are in 5th grade you can look in your Science text book , and it should say it)
Red blood cells provide oxygen from the lungs to the various tissues in the body, and in so doing return CO2 to the lungs to be breathed out. They don't serve an immunological function.
Red blood cells give oxygen to the lungs. Also, they carry oxygen out to the body from the heart.
