The lungs. Oxygen enters our lungs as part of the air that we breathe. It goes to the blood vessels deep in our lungs and then on to all parts of our body.
The organ that takes in oxygen is the lungs. While in breathing process, oxygen passes through the lungs from the air by means of inhaling.
Mostly arteries.

All the organ system in the body needs glucose and oxygen for survival

Circulatory system
placenta
The spiracles (tiny holes in the sides of the animal) and the trachea (small tubes attached to them).
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
The lungs are the organ that gets oxygen into the blood.
The placenta is where the material between mother and child, like nutrients and oxygen, travel from one to another.
