What else can I help you with?
Where does O2 come from in your alveoli?
The plants and algae around the world.from air normal
What do a frogs lungs do?
The lungs are an exchange point where CO2 leaves and O2 enters the blood
Where in the human body is o2 and co2 exchanged?
Oxygen (O2) is exchanged for carbon dioxide (CO2) in the lungs. In the alveoli, tiny air sacs in the lungs, oxygen from the air is transferred into the bloodstream while carbon dioxide from the blood is released into the air to be exhaled.
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
Air passage ways between trachea and lungs?
air enters the mouth or nose into the nasal cavity, it passes the eppiglottis and larynx then it enters the trachea where it goes onto the bronchi which divide into bronchioles which divide into the Alveoli where gases co2 and o2 are echanged then back to the lungs and to the heart through the polmonary vein.
How the movement of oxygen takes place in human?
During Inhalation the Oxygen enters the Alveoli of the lungs . The alveoli is surrounded by very tiny Blood vessels called Capillaries . Through Diffusion The O2 Moves out of the alveoli and into the Blood . Now the Blood carries it all over to the body with the help of Hemoglobin .The Blood Passes through Tissues then the O2 diffuses into the cells due to its higher concentration in the blood .The O2 Combines with the digested food present in the cells to give out Energy . So this is how O2 moves . Hope This Helped Thanks
Why does blood enter the lungs?
they enter the lungs in order to obtain oxygen and get rid of carbon dioxide. this process occurs in the alveolus of the lungs by diffusion.
What substance needed by the body cells enters the body through the lungs?
O2 and Co2, but we breathe out the Co2 again + the O2 which is converted in more Co2
Carries oxygen in blood?
The haemoglobin molecule, because it has an Iron atom at its core, will carry four oxygen (O2) molecules, per trip, from the capillaries in the lungs to capillaries elsewhere, where the O2 is released into all of these tissues, thereby enabling cellular O2 requiring processes..
What happens to the blood as it passes through the lungs?
There are two types of circulations, known as lesser and greater circulation. They are placed in series. say blood enters in right atrium through superior and inferior vena cave. Then it enters right ventricle. Then it passes to lungs, via pulmonary trunk. After purification from here it goes to left atrium. From it goes to left venrticle. From left ventricle it goes to all the body, but lungs. then from superior and inferior vena cave it again enters the left atrium.
Why do the walls of the capillaries and aveoli need to be thin?
The walls of alveoli are thin to allow the exchange of gases (Co2 and O2) between blood capillaries and the aveoli in the lungs.
How does the oxygen get into cells?
oxygen (O2) enters the body via respiration (breathing) it enters small pouches in the lungs called alveoli. these alveoli are surrounded by tiny blood vessels called capillaries. there is an exchange at these alveoli, carbon dioxide (CO2) exits the blood and O2 enters the blood. this freshly oxygenated blood is now returned via the pulmonary vein to the Left side of the heart. the left ventricle pumps blood to the body. as the blood vessels get smaller they again form capillaries. there is another exchange of gasses, O2 is transferred out to the cells and CO2 (the waste product from cellular metabolism) is transferred to the blood. the Deoxygenated blood is then returned via the venous system to the right side of the heart. the deoxygenated blood is pumped back to the lungs and the alveoli via the pulmonary artery. and then the whole cycle starts over again.hope this helps :)
