The lungs are part of the respiratory system that with the circutory system add oxygen to your blood.
Bears, like all mammals, obtain oxygen through respiration. They take in oxygen from the air through their nostrils or mouths, which then enters their lungs where it is exchanged for carbon dioxide. The oxygen is then transported throughout their body via the bloodstream to fuel their cells and metabolism.
The Respiratory system. We breathe oxygen containing air into our lungs. Our hearts send 'old' blood to the lungs where the carbon dioxide is removed and oxygen added, and that oxygen enriched blood is carried around the body until it lands up in the lungs again. So is it really a joint effort by the circulatory system and the respiratory system.
The air we breathe is about 78% nitrogen and 21% oxygen. While we do breathe in more nitrogen than oxygen, our lungs extract and use the oxygen for cellular respiration, which is essential for producing energy, and we exhale the nitrogen along with other gases. This process helps maintain the balance of gases in our bloodstream and tissues.
The easiest way to describe it is this: at sea level 100 units of air will contain 21 units of oxygen. As you go higher there is less oxygen per unit of air so 100 units of air on Everest may only contain 15 units of oxygen (these aren't accurate figures). The body needs oxygen to respire: C6H12O6 (aq) + 6O2 (g) → 6CO2 (g) + 6H2O + 36( to 38) ATP Respiration is the oxidation of glucose to produce energy- ATP. Therefore up higher the body will need to breath more to get the same amount of oxygen inside of the body so it can then respire and produce energy.
Taking in oxygen and giving out carbon dioxide is called breathing. Breathing is only a part of the process Respiration. In respiration, th lungs take in oxygen, which mixes with blood and is then circulated to each and every cell of the body. After this, in a cell, the oxygen is utilised for oxidation of food materials to generate energy for various metabolic processes. This process liberates carbon dioxide since it is a chemical reaction involving many steps. This carbon dioxide is then carried from each cell by the blood to reach the lungs where it is expelled out.
Your nose and mouth.
The oxygen your body needs comes from the air you breathe. When you inhale, your lungs take in oxygen from the air, and this oxygen is carried to all the cells in your body through your bloodstream to be used in various metabolic processes.
most people by measuring the amount of CO2 (carbon dioxide) in your bloodstream. if you have COPD then the body checks on the amount of oxygen in the bloodstream

Your body takes in oxygen through the respiratory system to help produce energy through a process called cellular respiration. Oxygen is transported via red blood cells in the bloodstream to all the cells in your body. These cells use oxygen to convert nutrients into energy that the body needs to function properly.
The respiratory system takes in oxygen through the lungs and transports it to the bloodstream. The circulatory system then carries oxygen-rich blood to all the cells in the body for cellular respiration.
The lungs take in oxygen from the air you breathe. Inside the lungs, oxygen is transferred to red blood cells in the bloodstream through a process called gas exchange in the alveoli. The red blood cells then carry the oxygen to various parts of the body.
air contains oxygen the body needs
The lungs are the part of the human body that absorbs oxygen directly from the air. When you breathe, the lungs take in oxygen from the air and transfer it to the bloodstream to be transported to cells throughout the body.
Oxygen is inhaled into the body through the respiratory system. When you breathe in, the air travels through the nose or mouth, down the windpipe, and into the lungs. In the lungs, oxygen is absorbed into the bloodstream and transported to all parts of the body.
When you breathe in, you take in oxygen from the air. In the lungs, oxygen is diffused into the bloodstream, while carbon dioxide is released from the bloodstream into the air sacs to be exhaled. This exchange of gases helps regulate the levels of oxygen and carbon dioxide in the body.
When you breathe in, your lungs take in oxygen from the air and deliver it to your bloodstream. The oxygen is then carried by red blood cells to your body's tissues, where it is used for energy production. At the same time, carbon dioxide, a waste product of the energy production process, is picked up by the bloodstream and transported back to the lungs to be exhaled out of the body.
