deoxygenated blood goes to the lungs which then goes down into the bigger bronchi and the get a little smaller into the bronchioles and then goes into the alveoli which is a grape like cluster where the gas exchange takes place and the bad goes out and the good air stays in. this is a dumbed down version of what really happens so if you like my answer you do or you may want to look it up on the internet to get a little better explinaiton

∙ 12y agoAlveoli are small, balloon-like sacs at the end of the small air passages in the lungs (the bronchiole). Oxygen is inhaled and absorbed into the bloodstream through the thin walls of each alveolus, by way of the pulmonary veins. Carbon dioxide from the pulmonary artery is exhaled as a waste product of the lungs.
The greater the surface area the lungs have for gas exchange, the greater is their efficiency to absorb oxygen. The 700 million (or more) alveoli found in both lungs, if flattened out, would cover an area of some 50-100 square yards. This is approximately the size of a tennis court, and is all neatly folded and bundled into the chest cavity. Each alveolus has a wall that is only one cell thick. A capillary wall has about the same thickness. The distance between air and blood is about 1/1000th of a millimeter. The oxygen is transported by the red blood cells, which squeeze single file through the pulmonary capillaries. Red cells that are packed with hemoglobin, or red pigment, which attracts the oxygen. Carbon dioxide is diffused in the same way back through the capillaries and alveolar walls to be exhaled.
The enormous surface area of the alveoli and the short diffusion distance between alveolar air and capillary blood quickly allows the blood to achieve an equilibrium with gases of the alveolar air. This function is further increased by the fact that each alveolus is surrounded by a capillary network so extensive that it forms an almost continuous sheet of blood around each alveolus.

Are the alveoli distal or proximal to the bronchi?
The alveoli and bronchi are both parts of the respiratory tree. The main parts of this structure, in the order of air passing through during inspiration are: trachea, bronchi, bronchioles, and alveoli. The alveoli are distal to the bronchi, because they are farther away from the center of the body then the bronchi.
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.
Which part of the respiratory system divides into smaller and similar tubes in a pattern that resembles the branches of a tree?
trachea --> bronchi -->bronchioles --> alveoli
What are the tiny air sacs called in the bronchi branches?
Alveoli
What does each lung consist?
Bronchi, Bronchioles and Alveoli. Bronchi and Bronchioles - transport systems Alveoli - Respiration occurs
Which of the following is not a component of the lungs bronchi or alveoli or pharynx?
alveoli
In each of the two lungs' the bronchi diviinto smaller branches which contain millions of tiny air sacs called?
Alveoli
What are the terminal ends of the bronchi?
Bronchi is branched in primary and secondary. bronchi is branch of bronchus.
What are the small air tubes that lead to the alveoli called?
The tubes that connect the bronchi with the alveoli are the bronchioles.
What are small air sacs in your lungs?
Alveoli, (from Latin alveoli, "little cavities") are an anatomical structure which have the form of hollow cavities. Found in the lung, the pulmonary alveoli are spherical extensions of the respiratory bronchioles (small air passages leading off the windpipe) and are the primary sites of gas exchange with the blood. Alveoli are only found in the lungs of mammals.
Branches of the windpide that lead into the lungs are the?
trachea- primary bronchi- secondary bronchi- tertiary bronchi- bronchiole- alveoli
What is at the tip of each bronchi-ole?
Alveoli.
