What is the component of respiratory system?
Some of the components of the respiratory system are the major structures like the throat, windpipe, and lungs. The other parts are smaller things like the alveoli, which are tiny sacs in the lungs where over a million of them work to transfer oxygen and carbon dioxide in and out of blood.
What is another example of diffusion other than osmosis?
The transfer of oxygen from the alveoli into the capillaries in the lungs, and the transfer of carbon dioxide from the capillaries into the alveoli (i.e. breathing in, and the oxygen going into the blood, and carbon dioxide going into the lungs to be expelled when we breathe out).
Why does smoking damage cilia and alveoli in the lungs?
Cilia are hair like structures that brush away particles in your lungs. When you smoke dust, pollen and other particles get stuffed into them and sit there. If they are there for a long time they form tar.
What was the first southern state?
The lining of the lung is made up of tissue called Alveoli. Alveoli are small "grapelike" structures which contain tiny capillaries. The heart pumps deoxygenated blood back to the lungs, exchange waste such as Carbon Dioxide and Nitrogen for a new "shipment" of oxygen and other air components which the body brought into the lungs through "inspiration. This exchange takes place in the alveoli. The oxygenated blood is then transported back to the heart then out through the arteries, arterioles and capillaries to the body, then waste is picked up by capillaries to venules then veins, back to the heart, then to the lungs and the process is started all over again.
What are alveoles?
An alveolus (plural: alveoli, from Latin alveolus, "little cavity") is an anatomical structure that has the form of a hollow cavity. Found in the lung, the pulmonary alveoli are spherical outcroppings of the respiratory sites of gas exchange with the blood. Alveoli are particular to mammalian lungs. Different structures are involved in gas exchange in other vertebrates.[1] They contain some collagen and elastic fibres, and they are lined with epithelium. The elastic fibers allow the alveoli to stretch as they fill with air when breathing in. They then spring back during breathing out in order to expel the carbon dioxide-rich air. The alveolar membrane is the gas-exchange surface.
What flows in the bronchioles?
The alveoli is found at the end of each Bronchiole and Bronchi. The alveoli gets rid of all the carbon dioxide that is in our lungs.If you need more help just ask another question and I'll be free to answer it.
Where does gas exchange occur in respiratory system?
AlveoliThe aveoli are small sacks in the lungs. A membrane that lines these sacks allows oxygen to move to the blood and carbon dioxide to move from the blood.Alveoli are particular to the lungs of mammals. Different structures are involved in gas exchange in other vertebrates.Air travels down the trachea, through thr bronchioles towards the terminal end of the respiratory tract, the alveoli. It is In the pulmonary alveolus that gas exchange with the surrounding capillary beds occurs. It is worth noting that alveoli are solely mammalian structures, so resporatory gas exchange occurs differently in other vertebrates and invertebrates.alveoli

Why does the exchange of gas take place in alveoli?
Alveoli are amazing little structures. Shaped like bunches of grapes, they give the largest surface area using the smallest space--like putting marbles in a box. All "sides" of their round shape allow the exchange of carbon dioxide and oxygen through tiny blood vessels. Because of their shape, alveoli are more effective than if we exchanged gases in other tissue of the lungs.
What tissue allows the rapid diffusion of oxygen form the aveoli in lungs to blood?
In the lungs, cells called alveoli form a thin membrane between the lungs and the capillaries. The alveoli extract oxygen from the air inhaled by the diaphragm, and transfers the oxygen to hemoglobin in red blood cells, which transport the oxygen to other parts of the body.
What are the harmful effects of pollution on the respiratory system?
Our lungs come in contact with ozone, lead, and other contaminants. This damages the alveoli and impairs lung function.
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
