Oxygen diffuses from the alveoli in the lungs into the blood by way of diffusion. The O2 passes across the thin cell membranes and is taken up in our capillaries by the haemoglobin in our red blood cells. Carbon dixide transfers in the opposite direction: from the blood plasma, across the cell membrane, and into the alveoli, where it is then exhaled.
The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. This barrier between air and blood averages about 1 micron (1/10,000 of a centimeter) in thickness. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body. Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide
You breath in oxygen which travels through the lungs into smaller and smaller passages called bronchi then it goes into grape like structures at the end called alveoli. The oxygen goes through the alveoli walls and into the capillary walls on the other side where the blood is located. Therefore giving the blood oxygen.
it transfers O2 in the blood and doesn't use CO2. CO2 is poisonous to the body.
Mostly nitrogen, oxygen, and carbon dioxide.
Carbon dioxide and water
oxygen enters the blood and carbon dioxide
Oximetry.
Oxygen and carbon dioxide easily pass back and forth between the alveoli and the blood through the capillaries.
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.

Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
Deoxygenated blood is low in oxygen and high in carbon dioxide.

The lung takes carbon dioxide out of your blood and replaces it with oxygen.
The mechanisms for transporting oxygen and carbon dioxide in the blood are the lungs. The blood vessels are also needed for transporting oxygen and dispelling carbon dioxide.
