External Nares (Nostrils) --> Nasal Cavity --> Inferior, Superior, & Middle Nasal Conchae --> Pharynx --> Larynx --> Trachea --> Primary Bronchi (Left & Right) --> Hilus --> Bronchioles --> Respiratory Bronchioles --> Alveolar Ducts --> Alveoli (the grape-like sacs) --> the the "spider web" of Pulmonary Capillaries.
What else can I help you with?
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.
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.
Actual molecule in rcbs that enables the blood cells to carry oxygen?
The molecule in red blood cells that enables them to carry oxygen is hemoglobin. Hemoglobin is a protein found in red blood cells that binds to oxygen in the lungs and releases it to body tissues as blood circulates. Each hemoglobin molecule can bind to four oxygen molecules.
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 does 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.
How is transported oxygen by blood in animals?
Oxygen binds to a molecule called hemoglobin in red blood cells.
What is the molecule in red blood cells that carries oxygen?
The molecule in red blood cells that carries oxygen is hemoglobin. Hemoglobin is a protein that binds to oxygen in the lungs and carries it to tissues throughout the body.
What is a specific molecule that diffuses into the blood at the lungs?
oxygen
What component of the blood carries the molecule oxygen?
Haemoglobin
What molecules in red blood cells contains the oxygen?
The hemoglobin molecule in red blood cells are responsible for transporting oxygen.
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.
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.
