It binds to red blood cells, which transport it to the tissues and organs.
Insects do have a respiratory system. The using organs called spiracles to introduce oxygen from the atmosphere into their bodies. These spiracles then let oxygen flow into the tracheal system which is a system of tubes that delivers oxygen to the parts of the body where it is needed.
During the respiratory system, oxygen travels through the respiratory tract and diffuses to the red blood cells from alveoli which receives carbon dioxide from the RBC's. The carbon dioxide comes from cells in the body. When the RBC's travel through the body to transfer oxygen to the cells it receives carbon dioxide. The carbon dioxide enters the alveoli and travels through the respiratory tract and is breathed out.
Respiratory System
When you inhale the oxygen, it enters to alveoli, end point of respiratory tract. Here oxygen enters the blood because of difference in concentration gradient. Carbon bi oxide goes inreversedirection. Again due to concentration gradient. So air going in lungs is rich in oxygen becomes less and replaced by carbon bi oxide. This oxygen isnecessaryforoxidation processes and carbon bi oxide is end product of oxidation processes.
It is false that if oxygen is present in a cell, pyruvic acid in glycolysis enters the chloroplasts. The pyruvic acid enters the mitochondria if oxygen is present in a cell.
Oxygen enters through the nose but is involved with the Respiratory System.
The respiratory system.
Oxygen, respiratory means breathing.
The function of the respiratory system is to provide the body with oxygen. Oxygen enters the body through the respiratory system and is carried in blood throughout the body.
All the cells in your body require oxygen
Alveoli.
Alveoli (plural) and alveolus (singular)
Oxygen enters via the lungs.
Insects do have a respiratory system. The using organs called spiracles to introduce oxygen from the atmosphere into their bodies. These spiracles then let oxygen flow into the tracheal system which is a system of tubes that delivers oxygen to the parts of the body where it is needed.
Oxygen enters the blood in the alveoli of the lungs
bronchi
The blood delivers Oxygen from the respiratory system to the digestive system and the other parts of the body as it travels around the body to give the air to go around us and breathe healthily
