How do you describe the sequence of oxygen carbon dioxide and blood flow in your own words?
Answer: 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. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.
What is the path of oxygen?
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Which sequence shows the transfer of oxygen from air to blood?
As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. Which sequence shows the transfer of oxygen for used by the body? Explanation: Air enters the lungs from the atmosphere and through the airwaves (trachea and bronchioles).
What happens to oxygenated blood when it is exhaled?
When we inhale the oxygen enters our respiratory system and the circulatory system transport it to different parts of our body (and every cells),when the oxygenated blood is transported it becomes deoxygenated (carries carbon dioxide) and it returns to the heart and lungs and we exhale it.
How do oxygen and CO2 get into the blood?
In your blood the oxygen and CO2 can find to your hemoglobin. The percentage of hemoglobin with oxygen attached is what’s called a hemoglobin saturation curve and it can be changed by things as simple as a change in pH, which is usually caused by a build up of carbonic acid, which is one way the CO2 is transported in the blood.
Where does gas exchange take place in the lungs?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
