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.

The lungs are the saclike organ in amphibians that take in oxygen from the air. Oxygen is then transferred from the lungs to the bloodstream through a process called respiration. This allows the amphibian to breathe and obtain the necessary oxygen for metabolic processes.
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.
Goldfish come to the top of the water to breathe air because they have a special organ called a labyrinth organ that allows them to take in oxygen from the surface.
The spiracles (tiny holes in the sides of the animal) and the trachea (small tubes attached to them).
Yes, gouramis have a labyrinth organ that allows them to breathe air in addition to extracting oxygen from water.
The placenta is the organ that allows nutrients to pass between the mother and embryo. It is connected to the uterus wall and facilitates the exchange of oxygen, nutrients, and waste products between the mother's bloodstream and the developing fetus.
