Trace molecule of oxygen from the external nares to the pulmonary capillaries of the lungs?

nose - nasal cavity - larynx - trachea - primary bronchus - secondary bronchi - tertiary bronchi - terminal bronchi oles - respiratory bronchioles - alveoli - alveolar sacs
the alveolar sacs contain the pulmonary capillaries. the actual gas exchange occur here by simple diffusion. O2 goes from the lungs into the O2 depleted RBC.

The movement of oxygen from the lung into the pulmonary capillaries is by?
diffusion
What is the site at which oxygen enters the pulmonary blood?
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.
Exchange of gases between alveolar air and pulmonary capillary blood?
Oxygen passes from the air sacs in the lungs to the blood in the capillaries, carbon dioxide passes the other way.
What is the exchange of oxygen an carbon dixoide through the cell membrain an capillaries?
This process, from the alveoli in the lungs, to the pulmonary capillaries, is generally termed "respiration".
What does the oxygen molecule do when it is in the alveoli?
It diffuses into the blood capillaries surrounding the alveoli.
How does oxygen-rich blood travel from the heart to capillaries around the body?
through pulmonary veins
When the oxygen goes into the bloodstream it goes into arteries veins or capillaries?
Oxygen moves into the lungs to the alveoli in the lungs into capillaries into pulmonary veins to the heart then to arteries that go through the rest of the body.
Do capillaries transfer waste filled blood from tissues into the pulmonary circulation?
The Capillaries transfers waste filled blood from the tissues into the Pulmonary circulation.capillariesTiny blood vessels that pass food and oxygen to cells and receive waste from cells.
Do arteries carry oxygen-rich blood to capillaries?
Systemic Arteries carry oxygen rich blood (also called oxygenated blood). Pulmonary Arteries carry oxygen poor (deoxygenated) blood
Trace a molecule of oxygen from the air until it reaches the blood?
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.

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.
