when your body's cells use O2 in cellular respiration they give off Co2 as a waste product which fills up your lungs. when you then inhale O2 into your lungs they enter air sacks made of a thin tissue that allows gasses to pass through. The O2 then diffuses into your blood stream while the Co2 diffuses out. Your lungs are now filled with Co2 in which you exhale wile your body's cell are producing more Co2. You then in hale and the cycle restarts.
O2= oxygen
Co2= carbon dioxide
diffusion= movement of the concentration from high to low
When oxygen is inhaled, it travels to the lungs. In the lungs, millions of tiny sacs called alveoli intertwine with a network of very small blood vessels. The alveoli allow carbon dioxide from the blood to be exchanged with oxygen in the lungs. The oxygen molecules are bound to hemoglobin, a protein found in red blood cells. From there the circulatory system carries the red blood cells through the body, and the oxygen is carried wherever it is needed.
Air to lung alveoli, across the epithelial [also capillary] barrier-lining of Cells to the heme-groups of hemoglobin found in red-blood-cells. Oxygen containing RBC's are then transported to another set of capillaries located [found] at the/our extremeties.
It is transported there by the bloodstream. Red blood-cells get their colour from a molecule called haemoglobin. When these molecules pass through the lungs they pick up oxygen, forming oxy-haemoglobin. When a molecule of this passes a cell which needs oxygen, the oxygen is stripped off, and haemolobin continues on it's journey. Note. Haemoglobin is dark red; oxy-haemoglobin is a brighter red. That's why arterial blood is a brighter red than venous blood.
Oxygen and glucose are two substances that pass into the blood. Oxygen is essential for cellular respiration, while glucose provides energy for cells.
The blood in the right atrium receives deoxygenated blood from the body through the superior and inferior vena cava. It then passes through the tricuspid valve into the right ventricle to be pumped to the lungs for oxygenation.
The process of simple diffusion. Oxygen moves from the alveoli into the blood where it binds to hemoglobin in red blood cells, while carbon dioxide moves from the blood into the alveoli to be exhaled out of the body.
The three gases that pass through the stoma are carbon dioxide (CO2), oxygen (O2), and water vapor (H2O). Carbon dioxide enters the plant through the stoma for photosynthesis, while oxygen and water vapor exit as byproducts.
alveoli
Oxygen and other gases pass through the capillaries.
The last valve oxygen-depleted blood must pass through before being pumped to the lungs is the pulmonary valve. This valve separates the right ventricle from the pulmonary artery and prevents blood from flowing back into the heart. Once the blood passes through this valve, it enters the pulmonary artery and travels to the lungs for oxygenation.
You breathe the oxygen into your lungs. The oxygen then dissolves into the water lining which is called the alveoli. Finally, the oxygen will cling to the red blood cells as they pass through the alveolar capillaries and now the oxygen is in the blood.
Oxygen in the alveoli diffuses across the thin alveolar membrane into the adjacent capillaries where it binds to hemoglobin in red blood cells. This oxygenated blood is then transported throughout the body to supply tissues and organs with oxygen for cellular respiration.
The function of the blood vessel is to pass oxygen through the body via the blood.
Oxygen and glucose are two substances that pass into the blood. Oxygen is essential for cellular respiration, while glucose provides energy for cells.

The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
The blood in the right atrium receives deoxygenated blood from the body through the superior and inferior vena cava. It then passes through the tricuspid valve into the right ventricle to be pumped to the lungs for oxygenation.
Oxygen is able to pass into your blood through diffusion. In the lungs, oxygen moves from the alveoli in the lungs into the surrounding capillaries where it binds to hemoglobin in red blood cells for transport throughout the body.
