Function of the lungs?

The Lungs are made up of millions of tiny air sacs called alveoli. These alveoli are like the millions of little holes in a sponge.\n\nJust out of curiosity, did you feel them in a dissection or something?

Lungs. Same as humans and most land mammals.

The two organs of the circlatory system are the heart and lungs.  Does that help?

In the space between the pleura, NOT in the lungs...outside the lungs!  Te pleura lines the outside of the lungs and the inside of the chest wall (giving a smooth surface for the lung movment when breathing) .

Lungs ~ it comes through the mouth and nose doesn't it?

muscular system helps you move.....with out that you couldnt move anywhere......respiratory helps you breath.......circulatory helps the blood move through the body and other fluids get where they are going

It protects the lungs, heart and other vital organs.

squamous cells: function primarily in alveolar gas exchange and fluid balance. \ncuboidal cells: responsible for pulmonary surfactant secretion and metabolism.

Blood has lots of functions.  It carries oxygen and nutrients.  It causes clotting.  It is the avenue which the kidneys use to remove waste from our bodies.

a.The volume of thoracic cage increases,the lung pressure increases when we breath in.\nb.Mycobacterium tuberculosis spreads when we breath in the air that contains the bacterium as a droplet.\nc.Diagnosis of TB.\nd.Avoiding contact with affected people,vaccination,etc...\ne.Ovary releases the ovum into the oviduct,that collects them & reaches the ampulla for fertilisation.\nf.It dissolves in the haemoglobin & passes thro' the tissues.\ng.The ovarian membranes protects the foetus-Amnion,Chorion & Allantois.\nh.Spread of insect borne diseases thro' insects like mosquitoes & flies.\nk.Insulin,the hormone secreated by beta cells of Islets of Langerhans(present in the pancreas) reduces the increase in Blood glucose level.

The upper respiratory tract also functions to warm and humidify the air you breath so this is one function that is lost. To counter this the air/oxygen mix should be warmed and humidified. If not the lining of the respiratory tract would become dried and damaged as a result.\n\nThe upper respiratory tract also serves to filter particles from the air so filters must be attached to the ventilator.

haha the answer above me is funny...what what exactly do you want to know about it? theres a lot to do with respiration...theres inspiration where the air is taken in..this is caused by a contraction of the diaphragm..thens there structures like the epiglotis, trachea, pharynx...then the oxygen goes to your lungs..where gas exchange occurs in the alveoli's...this is done by some complicated process that i dont understand really..i didnt really pay attention during this part of physiology/biology class. haha. anyway, the oxygen is picked up by the pulmonary artery and goes to the rest of the body through the aorta...uhh, i can think of anything else..hope this helps!

First the diaphragm under the lung expands creating an area of low pressure in the lungs leading to the air from outside the body to rush into the mouth to the trachea to the bronchi to bronchi oles and then to alveoli. The lung is like a sponge and has an increasingly small system of tubes that are lined with microscopic alveoli that are lined with capillaries. When O2 molecules reach the alveoli they diffuse oppositely to carbon dioxide which is the body's waste gas. The blood cells go from the capillaries in the alveoli to venules to the pulmonary vein where it enters the left atrium and then goes to the left ventricle where it is rushed out of the heart through the aorta where it divides into other arteries, arterioles, and then capillaries.

Oxygen (as O2) enters the lungs and diffuses through the thin layer of epithelial cells into the blood stream, where it binds one of four sites on hemoglobin.  The hemoglobin carries the oxygen to the heart, where it is then pumped out to the tissues of the body.  Tissues uptake oxgen as needed, and give CO2 in return to the blood stream.  The CO2 is then carried back to the lungs, where more oxygen is taken up.\n\nOxygen serves as an oxidizer, while fuels (such as sugar and fats) serve as reducers.  The oxygen acts in what are called "Oxidation/reduction" reactions (aka Redox--defined by a transfer of electrons) which release an excess of energy.  That energy is used to make ATP (adenosine triphosphate), which acts as the energy carrying molecule of choice by the body.  The systems used to make ATP are primarily glycolysis and the electron transport chain.

The heart is what pumps blood and is the centerpiece of the circulatory system. Without it the blood could not carry the nutrients the body needs. The lungs take in oxygen to help feed the bloodstream. Basically both organs do the same job, just in different ways and for the same end. Keeping YOUR blood infused with the nutrients the body requires to sustain itself. Hope this helps.

The first is surface area. The mammalian lung has a huge number pf alveoli compared to lung structures of reptiles and amphibians. The greater the surface area available for gas exchange, the more efficient will be the gas exhange.\n\nThe second requirement for gas exchange is assisted by the mamallian heart of four chambers as opposed to reptilian and many other hearts. There is an enormous amount of the circulatory system that passes directly to the pulmonary arteries and veins. Thus there is sufficient blood circulation in the lung area to remove oxygen and transfer it to the rest of the body.\n\nComparative biology will show far fewer alveoli in non-mammalian hearts (with the exception of birds). The other thing notable from compataive anatomy is that the mamallian heart (and that of birds) is a four chambered pump that does not mix unoxygenated blood with blood that has been oxygentated.\n\nSurface area and increased opportunities for deoxygenated hemoglobin to accept oxygen due to more efficient heart action.

There are two organ systems that work in conjunction with each other to provide tissues with oxygen and remove carbon dioxide.  Those are the respiratory and the circulatory system (the major organs of these systems being the lungs and the heart respectively).\n\nNutrients are provided by the combined actions of the digestive and circulatory system, and wastes are removed through the combined actions of the circulatory and excretory systems.
