Oxygen
The symbol for this element is O,as used in the chemical compound in water, H2O
The process involved in the passage of gas between the alveolus and the blood is called gas exchange. This occurs through diffusion, where oxygen moves from the alveolus into the capillaries and carbon dioxide moves from the capillaries into the alveolus.
Heart to arteries to capillaries to veins.
They are small blood vessels that take deoxygenated blood to the heart. Gas exchange.
The three types of blood tubes are arteries, veins and capillaries. Arteries carry blood away from the heart, and veins carry blood to the heart. Capillaries connect small arteries to small veins, and are the site of gas exchange.
Two primary gases are found in the blood stream. Leaving the capillaries and going out into the tissue is OXYGEN which was carried by the hemoglobin in the red blood cell. Leaving the tissue and entering the capillary is CARBON DIOXIDE or "CO2" which is transported via carbonated water (aka carbonic acid) in the plasma of the blood stream.
Gas moves by diffusion from areas of high concentration to areas of low concentration. In the lungs, oxygen moves from the alveolar ducts into the blood in the capillaries, while carbon dioxide moves from the blood into the alveolar ducts to be exhaled.
All arteries carry oxygen-rich blood from the heart to capillaries throughout the body. Likewise, veins carry CO2=loaded blood back to the lungs for re-oxygenization.
Blood vessels transport blood throughout the body. There are different types of blood vessels - the main ones being arteries, veins and capillaries. Arteries carry blood away from the heart, veins carry blood towards the heart and capillaries are where gas exchange occurs.
carbon dioxide
Gas exchange primarily occurs in the capillaries, not in arteries or veins. Arteries carry oxygen-rich blood away from the heart to tissues, while veins return oxygen-poor blood back to the heart. The capillaries, which are small blood vessels that connect arteries and veins, facilitate the exchange of oxygen and carbon dioxide between the blood and surrounding tissues. Therefore, gas exchange does not take place directly in arteries or veins.
The capillaries are the blood vessels that connect arteries and veins. Capillaries are the site of gas exchange in the body.
Gas exchange primarily occurs in the alveoli of the lungs. The alveoli are tiny air sacs where oxygen from the inhaled air diffuses into the bloodstream and carbon dioxide from the blood diffuses into the alveoli to be exhaled. This exchange of gases is facilitated by the thin walls of the alveoli and the surrounding capillaries.
