Oxygen is entered through the mouth and carbon dioxide is released out of the mouth.
Oxygen is brought into the blood stream by inhalation. Carbon dioxide moves out of the cells, into the blood, and taken to the lungs to be exhaled. Oxygen in, carbon dioxide out.
Oxygen and carbon dioxide easily pass back and forth between the alveoli and the blood through the capillaries.
Carbon dioxide rich blood, which is red blood cells lacking oxygen but high in carbon dioxide concentration.These blood cells have circulated through the body and given up much of its oxygen while collecting waste carbon dioxide. The pulmonary artery carries this blood from the heart to the lungs, where it picks up a fresh supply of oxygen and eliminates carbon dioxide.
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
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 oxygen releases carbon dioxide
the oxygen releases 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.
The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygenenters the lungs and reaches the alveoli. 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.
