Check out these fun lung facts
for kids. Learn more about the amazing organs that allow us to breathe in the
oxygen we need to live as well as breathe out the waste product carbon dioxide.
Read on and enjoy all the interesting facts about lungs. The primary functions
of your lungs are to transport oxygen from the air you breathe into your
bloodstream while taking away carbon dioxide, which is released into the air
when you breathe out. Most vertebrate animals (animals with spines) have two
lungs.Your left and right lungs aren’t exactly the same.
The lung on the left side of your
body is divided into two lobes while the lung on your right side is divided
into three. The left lung is also fish and a few snails. In mammals and the more complex life forms, the two lungs are located near the backbone on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxidefrom the bloodstream into the atmosphere. A large surface area is needed for this exchange of gases which is accomplished by the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alveoli. To understand the anatomy of the lungs, the passage of air through the nose and mouth to the alveoli must be studied. The progression of air through either the mouth or the nose, travels through the nasopharynx, oropharynx, larynx, and the trachea (windpipe). The air passes down the trachea, which divides into two main bronchi; these branch to the left and right slightly smaller, allowing room for your
heart. Can you live without one lung? Yes you can, it limits your physical
ability but doesn’t stop you from living a relatively normal life. Many people
around the world live with just one lung. People who have a large lung capacity
can send oxygen around their body faster. You can increase you lung capacity
with regular exercise. When resting, the average adult breathes around 12 to 20
times a minute. An average person breathes in around 11,000 litres of air every
day. The study of lung diseases is known as pulmonology. As well as other parts
of your body and your general health, smoking is bad for your lungs. Smoking
can cause lung cancer among other lung affecting diseases.
Asthma is a common disease that
affects the lungs. Asthma attacks happen when your airways narrow after being
irritated. The narrow airways make it hard for you to breathe in air. Pneumonia
is a dangerous disease that makes it harder for your lungs to absorb oxygen
from the air you breathe. Other lung diseases include emphysema, tuberculosis
and bronchitis. The lung is the essential
respiration organ in many air-breathing animals, including mosttetrapods, a few
fish and a few snails. In mammals and the more complex life forms, the two
lungs are located near the backbone on either side of the heart. Their principal
function is to transport oxygen from the atmosphere into the bloodstream, and
to release carbon dioxidefrom the bloodstream into the atmosphere. A large
surface area is needed for this exchange of gases which is accomplished by the
mosaic of specialized cells that form millions of tiny, exceptionally
thin-walled air sacs called alveoli. To understand the anatomy of the lungs,
the passage of air through the nose and mouth to the alveoli must be studied.
The progression of air through either the mouth or the nose, travels through
the nasopharynx, oropharynx, larynx, and the trachea (windpipe). The air passes
down the trachea, which divides into two main bronchi; these branch to the left
and right lungs where they progressively subdivide into a system of bronchi and
bronchioles until the alveoli are reached. These many alveoli are where the gas
exchange of carbon dioxideand oxygen takes place. Breathing is driven by
muscular action; in early tetrapods, air was driven into the lungs by
thepharyngeal muscles via buccal pumping, which is still found in amphibians.
Reptiles, birdsand mammals use their musculoskeletal system to support and
foster breathing. Medical terms related to the lung often begin with pulmo-,
such as in the (adjectival form:pulmonary) or from the Latin pulmonarius
("of the lungs"), or with pneumo- (from Greekπνεύμων
"lung").
