your lungs
The lungs are responsible for picking up oxygen from the air we breathe. Oxygen diffuses across the thin walls of the lung's air sacs (alveoli) into the surrounding blood vessels, where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
i think it`s through blood stream
Oxygen is a specific molecule that diffuses into the blood in the lungs during the process of respiration. This exchange occurs in the alveoli, where oxygen moves from the air sacs into the bloodstream to be transported to tissues in the body.
In the mammalian fetus, the exchange of carbon dioxide for oxygen occurs in the placenta. The placenta is a temporary organ that develops during pregnancy to allow for the transfer of gases, nutrients, and wastes between the maternal and fetal bloodstreams. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide from the fetus diffuses into the mother's blood for elimination.
The lungs diffuse oxygen into the bloodstream. Oxygen from the air we breathe is absorbed into the bloodstream through the walls of the alveoli in the lungs, where it is then carried by red blood cells to be delivered to the body's tissues.
Oxygen is transported in blood by binding to the Hemoglobins. Then Hemoglobin will carry O2 through out our body. When blood reach to the organ, or cells, DIFFUSION process will be activated, O2 from High concentration (blood stream) diffuses to the Low concentration (cells).
The organ that supplies a human's bloodstream with oxygen from the air is the lungs. When we inhale, air enters the lungs, and oxygen from the air diffuses into the bloodstream through the alveoli, tiny air sacs where gas exchange occurs. This oxygen-rich blood is then circulated throughout the body to supply tissues and organs.
The embryo receives oxygen via the mother's bloodstream through the placenta. This organ provides a direct connection between the mother and the developing fetus, allowing for the exchange of oxygen and nutrients. Oxygen from the mother's red blood cells diffuses across the placental barrier and enters the fetal blood circulation.
The brain consumes 40% of the oxygen in your blood.
