parts of the lower respiratory tract?
The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygenenters the lungs and reaches the alveoli. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
The respiratory system is involved in removing carbon dioxide from the body. Carbon dioxide is carried to the alveoli by the circulatory system. There, it diffuses across the membrane into the alveoli and is exhaled.
The respiratory system functions to bring oxygen into the body and make it available to the cells, and to remove carbon dioxide from the cells and expel it. The cardiovascular system works with the respiratory system by picking up the inhaled oxygen and delivering it to the body's cells, and by taking carbon dioxide from cells and delivering it to the lungs to be exhaled.
The gases that are exchanged are oxygen and carbon dioxide.
The circulatory system takes up oxygen, and releases carbon dioxide.
The respiratory system moves oxygen in and carbon dioxide (CO2) out.
The respiratory system utilises oxygen from the environmrntal gases and expires carbon dioxide (CO2).
The primary function of respiratory system is to provide blood with supply of oxygen, which is needed by every part in the body. This is done via breathing. Oxygen is inhaled while carbon dioxide or waste is exhaled.
we breathe in oxygen and we release carbon dioxide
The carbon dioxide enter the lungs & exchange of gasses takes place. The oxygenated blood still flows in to our body.. then, it flows back to our heart. The carbon dioxide will be inhaled by the nose and when we exhaled carbon dioxide in our body will pass out through our nose. if you want to answer that we inhale oxygen....that's not true because our world is very polluted.So, we inhale CARBON DIOXIDE.
