Lungs
Lungs are a pair of elastic and spongy organs that help the body breathe. They are present inside the rib cage in thoracic cavity of humans.

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
What is the prognosis for a patient with esophageal cancer?
Since most patients are diagnosed when the cancer has spread to lymph nodes or other structures, the prognosis for esophageal cancer is poor. Generally, no more than half of all patients are candidates for curative treatment. Even if.
They are called alveoli
How is oxygen and carbon dioxide exchanged in the bronchi and lungs?
When air is inhaled it is brought into aveoli, which are very small sacs surrounded by capilaries. These capilaries have blood flowing through them, and oxygen diffuses into the blood and carbon dioxide diffuses out of the blood and into the lungs.
The right lung has 3 lungs. The left lung has two to make room for the <3 heart
Where in the lungs does breathed in oxygen swap with carbon dioxide and water in the blood?
You have it backwards. In the tissues, the hemoglobin in the red blood cells pick up carbon dioxide (CO2) and releases oxygen (O2) to the cells of the tissues. It is then carried to the lungs where the opposite occurs: oxygen (O2) is picked up from the air and carbon dioxide (CO2 ) is released into the air and you expel it.
Does lung tissue repair itself after stopping smoking?
exercise more, you cough more, clearing out your lungs and airways.
This is good. Most likely you'll breath easier and build up your
endurance as you get further and further from your last cigarette.
What determines in which direction carbon dioxide and oxygen will diffuse in the lungs?
pressure difference between carbon dioxide and oxygen level between pulmonary artery and alveolar space
The condition is called emphysema (literally, swelling).
The condition is part of COPD (chronic obstructive pulmonary disease) and results from the destruction of the supporting structures of the lung. This prevents the normal exchange of oxygen in the alveoli. Smoking introduces tar residue into the lungs that causes significant tissue damage.
The tiny air sacs in the lungs that take oxygen from the air and put it into the blood?
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.
Recieves blood from the lungs?
I assume you're asking how the heart delivers blood to the lungs and back to the heart.
When your heart beats, deoxygenated blood is delivered to the right atrium via the superior vena cava and inferior vena cava, which are large veins. The right atrium then pumps the blood to the right ventricle which pumps it to the lungs for oxygenation via the pulmonary artery. Cellular respiration occurs in the lungs and your blood becomes saturated with the oxygen you're breathing and gets rid of its waste product (Co2) when you exhale. The now oxygenated blood gets pumped back to the heart via the pulmonary vein and enters the left atrium. The left atrium pumps it to the left ventricle and the left ventricle pumps it to the ascending and descending aorta, which delivers it to the rest of your body and organs.
What happens to the pressure inside the lungs as the volume of the thorax increase?
As your diaphragm expands, the pressure in your thoracic cavity decreases. Air rushes into the partial vacuum, and you inhale.
How are alveoli and bronchi related?
Bronchioles are part of the respiratory system and branch from the bronchus. Air from the bronchus enters the terminal bronchioles that terminate in air sacs known as alveoli.
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.
The more little sacs you have, the more surface area there is - and more surface area means more spots for oxygen to enter the blood system.
What part of the lung is oxygenated?
the alveoli
The oxygen in the lungs goes in to alveoli, which have a large surface area so that the oxygen can diffuse (spread out into) the capillaries surrounding the lungs.
It is part of the reproductive system. it is the opening to the birth canal
You can tell if its a right lung or not simply by looking at two structures. The right lung has three lobes and the left only two. Also, the heart is more towards the left side of the body so there is a bigger "indent" on the left lung.
Show picture of a healthy lung?
A smokers lungs are black and covered in a yellowish substance called infection. Once a smoker stops smoking, there lungs begin to heal themselves. The longer you stay not smoking the better your lungs will get.
How is the lungs affected when you breath the dirty air?
Particles can get into the lungs and can damage them or they can make the airways swell up and make it difficult to breath. Some types of pollution, like ciggarete smoke, can hurt the cells in the lungs
What do your bronchi and brochioles do?
bronchi and brochioles provide air to the lung. They carry both oxygen and co2.
