In the body it is the pulmonary system.
Cellular Reproduction
The respiratory system gets the oxygen from the air and releases CO2 from our body. The circulatory systemdistributes oxygen to individual cells and carries CO2 waste to the respiratory system.
The main waste gas produced by cells is carbon dioxide.This is produced by the process of respiration:glucose + oxygen ----> water + carbon dioxide
The blood or the circulatory system carries oxygen and nutrients to the tissues and removes waste from them
No the digestive system cannot absorb oxygen. The digestive system absorbs nutrients, eliminates waste, break down foods, and more.
the respiratory system brings oxygen to the blood and removes the waste gas carbon dioxide
the respiratory system brings oxygen to the blood and removes the waste gas carbon dioxide
The respiratory system supplies oxygen to the blood cells and removes waste gases from the blood cells. Carbon dioxide is the primary waste gas that is removed.
The nervous system controls the rate of the heart. In turn the cardiovascular system brings oxygen & nutrients to the brain & the removes all the waste.
In Biology, respiration refers to cellular respiration - the process where cells use oxygen and glucose to produce energy. Breathing refers to taking air into your lungs and exhaling waste gases.
When your lungs move to bring in air and remove gases you are breathing.
Breathing or Respiration
Oxygen and carbon dioxide are exchanged by way of the circulatory system. Cells use oxygen for energy and produce carbon dioxide as a waste. Capillaries are where this exchange occurs. Veins carry this product back to the heart. This blood goes to the lungs were you blow off the carbon dioxide and take in oxygen. So the circulatory system and lungs work together to exchange gases.
You inhale due to expanding and contracting your diaphram. The respiratory system provides oxygen to your blood, and expells waste gases such as carbon dioxide.
It is called breathing. Breathing is the movement of the chest that brings air into the lungs and removes waste gases. The air entering the lungs contain oxygen. It passes from the lungs into the circulatory system because there is less oxygen in blood when it enters the lungs than in the cells of the lungs.

Basically, the lungs exchange inwards of oxygen for outwards of waste gases.
