Oxygen enters the lungs through inhalation. It is transfered through the thin alveolar tissue to the red blood cells of the pulmonary arteries through an intricate diffusion process. More specifically, the oxygen is bound by the hemoglobin contained within the RBC's. This oxygenated (red) blood is circulated throughout the body until it reaches the capillaries. Tissue is then supplied oxygen by a process called perfusion, the unloading of the oxygen bound within hemoglobin to the surrounding cells. The deoxygenated blood is returned back to the heart for a new cycle. The oxygen is to be used in oxidative phosphorylation (the creation of cellular energy) to continue healthy tissue function
After oxygen leaves the lungs, it enters the bloodstream through the alveoli in the lungs. It then travels to the heart, which pumps the oxygen-rich blood to various tissues and organs in the body. The oxygen is used by cells in these tissues and organs for energy production through a process called cellular respiration.
Oxygen enters our body through the process of respiration. When we inhale, air containing oxygen enters our lungs. The oxygen then diffuses from the air sacs in the lungs into the bloodstream, where it is carried by red blood cells to tissues throughout the body.
The lungs are the organs where oxygen enters the body and carbon dioxide leaves it through the process of respiration. Oxygen is taken in when breathing and carbon dioxide is released when exhaling.
Oxygen enters the blood through the process of respiration in the lungs. In the lungs, oxygen diffuses from the alveoli into the blood capillaries surrounding them. It then binds to hemoglobin in red blood cells for transport to tissues throughout the body.
Carbon dioxide enters through stomata in leaves, which is needed for photosynthesis. Oxygen and water vapor also exit through the stomata as byproducts of the photosynthesis process.
Oxygen and carbon dioxide are exchanged in body tissues through the process of diffusion. Oxygen in the blood enters the tissue cells, where it is used for cellular respiration. Carbon dioxide, a byproduct of this process, moves from the cells into the blood to be transported back to the lungs for exhalation.
This process is called gas exchange. In the lungs, oxygen enters the bloodstream through diffusion across the alveolar membrane, where it binds to hemoglobin in red blood cells for transportation to tissues.
The air that enters the lungs is richer in oxygen when it enters the lungs. when it leaves it has more carbon dioxide and less oxygen as the lungs expel carbon dioxde and some unused oxygen.
NUTRIENTS AND OXYGEN also water, minerals, and vitamins
The blood leaves the heart through the aorta, the largest artery in the body. From there, it travels to smaller arteries and arterioles, ultimately reaching the capillaries where oxygen and nutrients are exchanged with tissues.
Oxygen enters the blood through the process of diffusion in the lungs. In the alveoli, oxygen from inhaled air diffuses into the blood in the surrounding capillaries, where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
