Yes it is.

The blood gets oxygen in the heart. Once the oxygen has been replenished, the blood is sent back out to the organs.
The simplest answer is "arteries," which generally carry oxygen-rich blood from the heart to the body, but the pulmonary veins also carry oxygen-rich blood. The lungs have oxygen that gives oxygen to the cells. Our body is a closed system so the blood never leaves the body system unless we are cut. After the blood has used up all of the oxygen it has the blood is recirculated through the heart and lungs once more! Thus this process goes on and on! An ARTERY carries oxygen rich or oxygenated blood from the heart to the body cells to give oxygen to them. I remember this by: Artery Away Arteries carry oxygen rich blood from the lungs to other parts of the body. Veins return oxygen poor blood to the heart where it gets recirculated through the lungs and then throughout the body again. The arteries.
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore there will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium
you call ioygen entering the blood stream
the answer to apex is passive.
The respiratory system is the first link in the process of oxygen delivery to the body's tissues. The transport of oxygen in the air you breathe to the alveoli in your lungs allows for the diffusion of oxygen into the blood stream.
The lungs utilize diffusion to transfer oxygen into the blood stream and take the CO2 out. Another example is the oxygen gradient set up in the ATP transfer cycle.
Diffusion
the heart pumps oxygenated blood back to the lungs
The blood leaving the lungs is loaded with oxygen, while blood entering the lungs is about to get oxygen from the respiratory system.
The blood entering from the lungs has a high oxygen content and the blood entering from the body is high in carbon dioxide.
the blood is given oxygen as it passes next to the alveoli in the lungs. The process by which the blood gets oxygen is called diffusion
by diffusion
by diffusion
Yes, oxygen is transferred to the blood via aveolae in the lungs.
