∙ 9y agoThe path of an oxygen molecule is oxygen outside - it is breathed into the lungs. Then it is absorbed into the blood vessels in the lungs and attaches to a hemoglobin molecule - the hemoglobin molecule carries the oxygen now into the heart and is pumped out to the body from the aorta - when the blood reaches an area that is low in oxygen it releases oxygen, which leaves the blood vessel and is absorbed into the tissue.

What is the pathway of an oxygen molecule from the atmosphere to its combination with a hemoglobin molecule?
Oxygen reaches the hemoglobin in the blood cells by entering the lungs. The key area of the lungs where the transfer of oxygen and carbon dioxide is made is called the alveoli. The Alveoli has very thin cell walls which allow oxygen and carbon dioxide to pass freely in and out of the blood stream.
What happens when blood reaches tissue that doesnt have enough oxygen?
Once oxygenated blood reaches the capillaries, the velocity of the blood is very slow - which favours the exchange of oxygen. Oxygen therefore diffuses across the walls of the capillaries into the tissues that need it.
The life cycle of an oxygen molecule?
an oxygen molecule is inhaled and then goes through the blood
How is oxygen transferred to the cell?
Oxygen is transferred to the cells by our red blood cells which have a special molecule called hemoglobin inside. The hemoglobin molecule binds to the oxygen molecule and the reb blood cells transports the oxygen to wherever it is needed.
How does oxygen circulate in the body?
Oxygen circulates through the body in blood. A molecule of oxygen (O2) from the lungs binds loosely to a molecule of hemoglobin in a red blood cell. The red blood cell travels through the capillaries and the oxygen molecule is released from the hemoglobin and is delivered to the cells.
What happens to the oxygen when it reaches the alveoli?
oxygen enters the blood and carbon dioxide
Carries oxygen?
The molecule that carries oxygen is the hemoglobin molecule. The cell that carries oxygen is the red blood cell.Blood. Red Blood cells. Or Haemoglobin in the red blood cells depending on what level you are looking at.The protein that carries oxygen in the blood is Haemoglobin(hemoglobin).

How is transported oxygen by blood in animals?
Oxygen binds to a molecule called hemoglobin in red blood cells.
What is a specific molecule that diffuses into the blood at the lungs?
oxygen
What component of the blood carries the molecule oxygen?
Haemoglobin
Actual molecule in rcbs that enables the blood cells to carry oxygen?
Hemoglobin is the molecule in red blood cells that allows the blood to carry oxygen. Iron is one of hemoglobin's main components.
