Carbon dioxide is a waste product of cellular respiration; it is exhaled through the lungs into the outside environment.
During respiration, Carbon Dioxide or CO2 is exhaled as a waste product.
Carbon dioxide is the atmospheric gas expelled by body cells. It is produced during cellular respiration and is then exhaled out of the body through the lungs.
Oxygen leaves the body through the process of respiration. During inhalation, oxygen is taken into the lungs and transferred to the bloodstream, where it is then distributed to cells in the body. As cells use oxygen for metabolic processes, carbon dioxide is produced and exchanged back through the bloodstream to the lungs, where it is exhaled out of the body.
Burning carbohydrates for energy in the muscles produces CO2 and H2O as by-products. These are then dissolved into the blood, and exhaled by the lungs. [This is why you need a pee after about an hour's exercise.]
Oxygen enters the blood through the lungs and binds to hemoglobin in red blood cells, which then carries it to cells throughout the body. Carbon dioxide is produced by cells during metabolism and is transported in the blood, mostly in the form of bicarbonate ions, to the lungs where it is exhaled out of the body.
You breathe in oxygen and breathe out carbon dioxide. Inhaling brings oxygen into your lungs, which is then absorbed by your blood for use by your body's cells. The carbon dioxide produced by your cells is carried back to your lungs and exhaled out of your body.
A molecule of oxygen enters the body through the respiratory system, where it is inhaled into the lungs. It then diffuses across the walls of the lungs into the bloodstream, where it is carried by red blood cells to tissues and cells throughout the body for cellular respiration. After being used by cells for energy production, carbon dioxide is produced as a waste product and transported back to the lungs to be exhaled.
Carbon dioxide is produced in the tissues through a process called cellular respiration. During this process, cells break down glucose to produce energy, releasing carbon dioxide as a byproduct. This carbon dioxide is then carried by the blood to the lungs, where it is exhaled out of the body.

'What is the importance of respiration in animals?' Respiration is the in and exhaling of gasses through the lungs. Oxygen is inhaled and carbon dioxide is exhaled. Oxygen is necessary for cell life, carbon dioxide is secreted by the cells and then exhaled by the lungs and nostrils as it is toxic to the body. (It has the same importance as in humans)
Red Blood Cells
Oxygen is transported in the human body by binding to hemoglobin in red blood cells. Hemoglobin carries oxygen from the lungs to tissues in the body, where it is released for cells to use in cellular respiration. The carbon dioxide produced is then transported back to the lungs to be exhaled.
