out through the blood
The system by which gases enter and leave the body is called the respiratory system. It includes organs such as the lungs, nose, and trachea that work together to allow for the exchange of oxygen and carbon dioxide between the body and the environment.
Examples of substances that enter the body include nutrients from food, oxygen from the air we breathe, and medications. Substances that leave the body include carbon dioxide when we exhale, waste products such as urine and sweat, and toxins removed by the liver.
Blood carries Oxygen through the body but, not food.
Gases enter and leave the body primarily through the process of respiration. Inhalation brings oxygen-rich air into the lungs, where oxygen diffuses into the bloodstream and carbon dioxide, a waste product of metabolism, is exchanged. During exhalation, carbon dioxide is expelled from the lungs back into the atmosphere. This gas exchange occurs in the alveoli, tiny air sacs in the lungs, facilitating the transfer of gases between the air and blood.
The respiratory system is responsible for delivering oxygen to the body through the process of breathing. Oxygen is inhaled into the lungs, where it is absorbed into the bloodstream and transported to cells throughout the body.
The red blood cells in your body contain oxygen and carbon dioxide. So, as the red blood cells travel through your bloodstream, the oxygen travels through to your heart, then your lungs, along with the oxygen.
diffusion
It is returned back to the heart to be sent throughout the body to deliver nutrients such as oxygen.

The capillaries are the site of diffusion of wastes, oxygen, and nutrients. This allows these materials to enter and leave body tissues.

Our body obtain oxygen to our body by breathing.
in photosynthesis leave do take carbondidxside from the air and leave oxygen

Oxygen is used for producing energy in your body. None of your body's cells can survive long without oxygen. Oxygen is needed for practically every single chemical reaction in your body.
The blood carries oxygen around your body and to the body's cells.
Oxygen content in the body refers to the amount of oxygen present in the blood. This is measured as arterial oxygen saturation (SaO2) or oxygen partial pressure (PaO2). Adequate oxygen content is vital for proper functioning of organs and tissues in the body.
