Oxygen enters the respiratory system through the nose or mouth and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the tiny air sacs called alveoli and is then transported into the bloodstream by binding to hemoglobin in red blood cells. The oxygen-rich blood is pumped by the heart to the rest of the body, where it is delivered to cells for energy production.
Oxygen is inhaled into the lungs and binds to hemoglobin in red blood cells. Hemoglobin then carries the oxygen-rich blood through the arteries to tissues in the body where it is released for cellular respiration. The oxygen-depleted blood returns to the lungs through the veins to pick up more oxygen.
When we breathe in, oxygen enters through the nose or mouth and travels down the windpipe (trachea) into the lungs. In the lungs, oxygen is absorbed by tiny air sacs called alveoli and then enters the bloodstream through tiny blood vessels called capillaries. The oxygen-rich blood is pumped from the lungs to the rest of the body by the heart, where it is used for energy production in cells through a process called cellular respiration.
Oxygen enters the body through the respiratory system, where it is inhaled and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the bloodstream through the alveoli. The oxygen-rich blood is then pumped by the heart to various parts of the body through arteries, eventually reaching individual cells where it is used in cellular respiration to produce energy.
Yes, when we breathe in, oxygen from the air enters our lungs. This oxygen is then absorbed into the bloodstream through tiny air sacs in the lungs called alveoli.
All organs of the respiratory pathway are important in delivering oxygen. These include the pharynx, trachea, and lungs.

In air through the passageways to the lungs, by diffusion through the alveoli into the blood, by diffusion out of the blood into the cells and through the cells into the mitochondria - where it ceases to exist as oxygen and becomes water.

The pathway of oxygen is like a tube or pipe in the breathing system.
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.

Pulmonary circulation :)
no, it is anaerobic metabolism. (without oxygen, rather than with oxygen.)
