How does carbon get back into the air from the food you eat?
when your food is converted into energy carbon dioxide is added to the blood stream and from there is exhaled out. i.e. when you breathe, oxygen in- carbon out
What do people breathe into the air?
People ( Humans) exhale nitrogen, carbon dioxide, and trace amounts of other gases. The nitrogen and other gases remain unreacted. from the atmosphere. Carbon dioxide is the result of breathing in (inhaling) oxygen travelling around the body in the blood stream, being used at the muscles etc., thereby being converted to carbon dioxide, which is carried in the blood stream to be exhaled. The carbon dioxide, being a heavy gas, falls to earth, is breathed in by green plant life, undergoes photosynthesis, and oxygen is released. The carbon compoent remains in the plant as biomass. The two gases , oxygen and carbon dioxide, are part of the oxygen/carbon cycle.
How does the oxygen that you breathe in get to the rest of your body?
You inhale oxygen/ It flows to the lungs. The lungs transfer the oxygen to the blood stream in exchange of carbon dioxide , which is exhaled. The blood stream flows to all parts of the body, and exchanged the oxygen for carbon dioxide, in muscles and other body organs. The carbon dioxide is then carried to the lungs and exhaled. This then begs the question, 'What happens to the carbon dioxide?. Carbon dioxide is a heavy gas and fall to the ground. Whereupon in is inhalked by green leafed plants; grass/leaves etc., In these plant, under the process of photsynthesis and in the presence of UV(sunlight) light, the plant breaks down the carbon dioxide into carbon , which is kept in the plant as biomass. The oxygen is then released back into the atmosphere for animals to breath. It is a natural cyclic process. That's putting it very simply. I am sure there are more complxities in the system.
Does your body need carbon dioxide to use the nutrients in the food you eat?
No. Carbon Dioxide is a waste gas and is removed from the blood stream.
How does your body obtain oxygen needed for repiration?
Its cellular respiration, which is the opposite of photo synthesis, which takes in oxygen through the nose or mouth then through the trachea to the lungs which extracts oxygen and sends it into the blood stream and then excretes carbon dioxide (exhale)
How do alveoli and capillaries help to get oxygen?
The alveoli is the point where the waste product of respiration (carbon dioxide) and oxygen are diffused into or out of the blood. Oxygen diffuses into the blood stream and are carried to the heart and carbon dioxide is diffused out of the lungs and expired. The alveoli have moist walls and are close to the capillaries which speeds up the process.
What is the pathway of an oxygen molecule from the atmosphere to its combination with a hemoglobin molecule?
Oxygen reaches the hemoglobin in the blood cells by entering the lungs. The key area of the lungs where the transfer of oxygen and carbon dioxide is made is called the alveoli. The Alveoli has very thin cell walls which allow oxygen and carbon dioxide to pass freely in and out of the blood stream.
What substance is removed from the blood stream by the alveoli in the lungs?
Carbon dioxide and water
What substance is removed from the blood stream by alveoli in the lungs?
Carbon dioxide and water
What is the tissue in the human body for breathing?
There is not really a tissue for breathing at all, more like an organ called the lungs. In the lungs, oxygen goes through the bronchial tubes into the alveoli In the alveoli the oxygen atoms are diffused into the blood stream and transported throughout the body by red blood cells. The same thing happens when you exhale, carbon dioxide is exchanged in the alveoli for oxygen, and the carbon dioxide exits the body, all in a matter of seconds.
The gas that goes into the blood stream through the blood is?
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.
Why do blood capillaries surround alveoli?
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
How does the gas exchange in the alveoli?
Gas is exchanged by diffusion. We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths. How does this waste material get into the air that we breathe out, or exhale? The thin walls of the alveoli actually have two purposes. When we breathe in, oxygen passes through the walls of the alveoli and into the blood. Carbon dioxide and water vapor then travel the opposite direction. They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth. In the alveoli, oxygen crosses over into the blood stream and carbon dioxide leaves the blood stream and enters the alveoli to be expelled through the lungs.
Are capillaries part of the lung?
Yes, capillaries form a network around the alveoli. It is through the alveolar walls and into the capillaries that oxygen enters the blood stream. Carbon dioxide leaves the blood by the reverse route.
What is the one use of iron?
To carry oxygen and carbon dioxide through the blood stream.
What is the use the use of ironing?
To carry oxygen and carbon dioxide through the blood stream.
What the site of gas exchange?
Gas exchange takes place inside the lungs in the alveoli. The alveoli are a "grape like" structure at the very end of the respiratory tract. The alveoli are composed of a very thin membrane that separates the blood vessels from the gas chambers. The thin membrane allows diffusion of oxygen into the blood stream and diffusion of carbon dioxide (CO2) out of the blood stream. Once the CO2 has diffused into the alveoli, it is exhaled.
