Lungs

It increases their RV (residual volume) and FRC (functional residual capacity) due to air trapping. It decreases the FEV1 and takes longer to finish their FVC (forced vital capacity) because of decreased flow rates. It also decreases the DLCO (difusion capacity) because of alveolar wall distruction.

Your left lung is smaller. The right lung has three lobes: superior, middle and inferior. The left lung has only two lobes: the superior and inferior. The heart takes up the space that would have otherwise been used for a middle lobe on the left lung.

Having a good lung capacity is important because you'll need it when it comes to sports and running. The exercises will really pay off once you get up in the good lung capacity area and i need to no mine right now to so i dont no wat im talkin bout but if u do plezzee help me answer this Q

The cilia hairs are actually found in the trachea. Their job is to push up and out excess mucus. Mucus is excreted to trap foreign particles that enter our respiratory tract. Nicotine hardens the mucus and cilia therefore rendering them useless, so the the trachea eventually starts closing up with mucus causing the person to cough (in order to remove this excess mucus).

The average maximum capacity is around 6 liters of air, but when you exhale approximately 1.2 liters stays in your lungs. An easy way to measure this is to take a balloon and take a deep breath, then inflate the balloon as much as you can with just that breath. Measure the resulting diameter of the balloon in centimeters, then use the formula:

Volume = (4 / 3)(3.1416)(diameter / 2)^3

Then divide by 1000 to get your lung capacity in liters.

If the lungs cannot function, the body can't get any oxygen. Oxygen is necessary for cellular respiration, the process that breaks down sugars to create energy for the cell. If cells cannot get get the energy they need to carry out vital functions, the cells will die, along with the organism they make up. In short: if the lungs don't function, the cells of the body get no oxygen, and the organism dies.

The lung volume that increases with exercise is vital capacity. When you exercise regularly, your body is more efficient at transporting and using oxygen, making vital capacity marginally bigger and exercise less difficult than someone who is out of shape.

The operating principle is a process called diffusion, which causes a substance to move from a region of high concentration to a region of lower concentration. Think of a squirt of perfume diffusing from a corner in a room until you can smell it everywhere in the room. Blood returning from the body to the lungs has a higher percentage of carbon dioxide (CO2) than the air inhaled into the lungs does. Conversely the concentration of oxygen (O2) in the inhaled air is greater than the concentration of O2 in the returning blood. Haemoglobin, which can (loosely) bond to both O2 and CO2, facilitates the exchange of gasses from respective regions of high concentration to the regions of lower concentration. Specifically, CO2 moves from the returning blood (higher concentration) to the air in the lungs (lower concentration) and oxygen moves in the other direction, thus oxygenating the blood.

Blood leaving the liver can reach the lungs only via the right heart. It travels for the liver through the hepatic [liver] vein to the vena cava [the main vein carrying blood leaving the body], into the right heart [first the right atrium, then the right ventricle], and then through the pulmonary [lung] artery to the lungs .

Actually, air is not cleaned before reaching the lungs. That is why severe lung damage is caused by living in highly polluted areas and smoking. In fact, air is breathed into the lungs, and transported through your circulatory system by way of red blood cells. It is finally cleaned when blood is pumped through the kidneys

it goes into the left atrium in your heart.

The lungs help you breathe and live so you can be healthy and do things. I'm a 6th grader and we have a project in science and my partners and I got picked to do repiratory system and this is what I know about lungs.

Residual volume allows gas exchange to go on continuously

Pulmonary veins receives blood from the lungs and brings it back to the heart to be circulated to the rest of your body. It is the only vein that carries blood to the heart (that's usually an artery's job).

Bird lungs have the same basic features as human lungs, such as a trachea, bronchi, lungs and capillaries etc, however birds' lungs operate in a cycling of air manner rather than a mixing action as in humans. Human lungs move air into alveoli at the extremities of the lungs and because it would require immense force to reopen a completely deflated alveoli and therefore they are never fully emptied and maintain "dead space". This means that when fresh air is moved in, there is mixing of fresh and dead space air. Birds on the other hand have a linear cycling of air meaning that the maximum amount of oxygen can reach the capillaries and pass into the blood stream. Hence bird respiration is more effective than human's, but in a way it needs to be due to the decreased size and intense need for efficiency during flight etc.

Cancer treatment can take many different forms, and it is always tailored to the individual patient. The decision on which type of treatment is the most appropriate depends on the type and location of cancer, the extent to which it.

Breathing is the simple answer.

Respiration is also an answer but respiration includes oxygen going into the bloff and throughout the body and Carbon Dioxide going back to the lungs and being exhaled.

The biggest is Carbon Dioxide (CO2). Of course, if a person were sick, they would also expel mucous etc, but exhaled air is rich in CO2 which is a waste product of cellular respiration during the production of ATP (glycolysis/Krebs).

Blood flows from the right ventricle of the heart into the lungs through the pulmonary arteries that carry deoxygenated blood. From the lungs, oxygenated blood flows through the pulmonary veins to the left atrium of the heart.

Oxygen is inhaled into the body through the nose or the mouth. It travels through the trachea, to the bronchi, then through the bronchial tubes, and finally settles in the alveoli, which are tiny sacs in the lungs. As the blood is pumped into the lungs through the pulmonary artery of the right ventricle of the heart, the oxygen-depleted blood goes to the capillaries which wraps the alveoli. In the capillaries, oxygen is given from the alveoli to the blood, and blood would drop of carbone dioxide into the alveoli. Once this process is complete, the blood would return to the heart, and the carbone dioxide would be expelled from the body as we exhale.
