Oxygen enters your nose,then goes through the trachea,to the bronchi,and last to your lungs.
Oxygen passes into the body through absorption in the lungs.
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.
vains pass through the outer layer of the lung and the oxygen (being soluble) passes through and oxygenates the blood
Oxygen passes through the membrane by diffusion. Most other molecules must be transported (carried) across by proteins which reside within the cell membrane.

Oxygen is the gas that passes from the lungs to the bloodstream.

Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.

Carbon Dioxide
When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream. During the same process, carbon dioxide is outgassed from the blood to the alveoli When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream.

Your body warms and moistens the air that passes into the lungs to make it easier for oxygen to pass into the bloodstream.
oxygen passes from the air to the blood, where it binds with haemoglobin to form oxyheamoglobin (how it is carried around the bloodstream) Carbon dioxide passes (diffuses) the other way ie. from blood to air inside alveolus, and from there exhaled.
Oxygen is obtained from the atmosphere by a process called Respiration, this involves inhaling air and filling small air sacs in the lung, at which point the oxgen passes into the bloodstream through a process called Diffusion.
