What gas exchange occurs in the alveoli and the body cells?
In alveoli: molecular oxigen - go in (to blood vessels) Carbon dioxid - go out (from blood vessels) In Cells: molecular oxigen - go in (to mitochondrion) Carbon dioxid - go out (from mitochondrion & cytoplasm)
What order does alveoli lung trachea nose and bronchi go in to reach the blood?
The correct order is:nosetracheamain bronchusbronchi (two) which is part of the lungsbronchioles - tinier than the bronchialveolismall capillaries surround each alveoli and cover each alveoli's surface-- CO2 passes from the alveoli to the venous blood supply; the blood passes O2 to alveoli and into the arterial blood supply
Blood goes into lung alveoli?
Blood does not go into the alveoli, that would only result from a hemorrhage. Blood does come close to the alveolar sacs via small capillaries that are there to perform an action called gas exchange. This process occurs as a result of diffusion and releases the carbon dioxide in the red blood cells and is replaced by oxygen to be carried to the body tissues and used in tissue respiration.
What is the structure of the atrium?
the left atrium is above the left ventricle. the blood which has been oxygenated from the lungs due to the gas exchange between the alveoli and capillaries comes here from the pulmonary artery this blood then gets sent to the left ventricle through the bicuspid valve this stops the backflow of blood but it allows the blood to go to the left ventricle but does not allow the blood to go back

How does the blood get oxygen?
by suking it
What is the main unit of oxygen exchange in the human lung?
the capillary's, they are based on the alveoli and they pass oxygen from the alveoli sacks through to the blood stream- ready to go to the heart and be pumped around the body
What are capillaries for?
The capillaries are where the gas and nutrient exchanges occur. Because in a closed circulation system the blood can't go outside the vessels, it must go to the capillary beds where it is about 1 cell thick to have diffusion. Alveoli in lungs are covered by capillaries to allow gas exchange to happen. The capillaries are most abundant of all the blood vessels, because most part of your body requires oxygen, and capillaries are where it can be given to cells.
The respiratory system is responsible for the exchange of what?
In the respiratory system, we see the exchange of gases. In this gas exchange, carbon dioxide (CO2) leaves the blood and goes into air in the lungs, and oxygen (O2) leaves the air in the lungs and goes into the blood. It is this gas exchange, which occurs in the alveoli, that permits oxygenation of the blood and keeps us alive.
What is the of Alveolus?
The alveolus is a air sac that holds the oxygen. It squashes the oxygen molecules so they diffuse from the alveolus into the capillary. From there, they attach themselves to deoxygenated Red Blood Cells. The oxygen in the blood plasma are also squashed and are diffused. They go from the capillary to the alveoli to get breathed out. The alveoli transfers the oxygen to the lung capillaries and oxygenates the blood, then it is breathed out as Carbon Dioxide.
The bronchi go directly into the alveoli.?
The passage way is Bronchi to Bronchioles then alveoli to alveolar ducts and exchange of gasses occurs in alveoli. So Answer is No..bronchi not goes directly to alveoli.
Does air go to alveoli first then bronchi?
Trachea> Bronchii> Bronchioles (smaller branches of bronchii) > Alveoli
