By breathing air into their lungs, where the Carbon Dioxide and Oxygen exchange occurs in the little air sacks known as alveolae.

Elephants breathe in air through their trunks, which then travels to their lungs. In the lungs, oxygen from the air is absorbed into the bloodstream and transported throughout the body to support cellular functions. This process is vital for sustaining an elephant's life.
Elephants, like all mammals, have red blood cells that contain hemoglobin molecules. Each hemoglobin molecule contains four iron atoms but does not contain any oxygen atoms. Oxygen is carried by red blood cells bound to the iron atoms in hemoglobin.
No, a mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, a mole of sodium, carrots, and elephants would all contain the same number of particles.
No, oxygen-17 and oxygen-18 are different isotopes of oxygen. They differ in the number of neutrons each atom contains. Oxygen-17 has 8 protons and 9 neutrons while oxygen-18 has 8 protons and 10 neutrons.
4 liters of oxygen is 100% oxygen because the volume is entirely filled with oxygen.
An oxygen conserving device delivers oxygen to the user only when they inhale, as opposed to continuously flowing oxygen. This helps to reduce the amount of oxygen wasted during exhalation and increases the efficiency of oxygen delivery.
