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 happens if you remove a navel ring after only one week?
Yes! I did and I've had no problems or pain(: i had a CBR hoop and i popped my ball off on accident :P i put neosporin on the ends or both my jewlrey and chased the ring with my new one! didn't hurt and now my rings pretty and ready for swimsuits. :D
Just because you didn't have problems doesn't make it right. Taking it out so soon increases the risk of infection unless you go back to your piercer and have them switch it out for some jewelry that is already autoclaved. Neosporin isn't great either. It's too thick and traps dust as well as prevents the piercings from "breathing". Just keep it in for at least another 2-3 weeks.
How do you know you have cancer?
If ovarian cancer is found and treated quickly, patients usually recover fully. This makes it very important to be aware of possible early symptoms. Signs to look for include swelling or bloating, a feeling of fullness, problems using the restroom, and pelvic or abdominal pain.
How does the diaphragm affect the lungs?
The diaphragm (also called the thoracic diaphragm) is a layer of muscle extending across the bottom of the ribcage. The diaphragm separates the thoracic cavity from the abdominal cavity. A diaphragm in anatomy is generally used to describe flat structures, like the urogenital and pelvic diaphragm. However when someone speaks of "the diaphragm" they generally mean the thoracic one. With regards to respiration, the diaphragm is a crucial aspect of the process. During inhalation, the diaphragm contracts, allowing the thoracic cavity to grow (the external intercostal muscles also aid expansion) allowing the lungs to take in more air. This also decreases intra-thoracic pressure, meaning when the thoracic cavity grows it creates suction which draws air into the lungs. When the diaphragm relaxes, air is exhaled thus relaxing (opposite of contracting) the diaphragm. This entire process happens every time a breath is taken.
What is a circumscribed nodule in the lung?
A hypoechoic nodule is an area of tissue that is less dense than the surrounding tissue. It is not likely to be cancer if it's circumscribed. Talk with your health care provider for advice specific to your situation.
What bones do you think protect the lungs?
The lungs and heart are protected and surrounded by the ribs called the rib cage.
What keeps food from entering your lungs?
The epiglottis is a flap of skin in the throat that covers the trachea (tube to your lungs) when you eat and the esophagus (tube to your digestive system) when you breathe. This keeps air from entering your stomach and food from entering your lungs. In addition, cilia and mucus line the trachea walls. They trap dust,bacteria and other bits and pieces that you don't want in your lungs.
Oxygenated blood from the lungs is received by the?
Heart. The right side of the heart pumps blood to the lungs through the pulmonary arteries. Blood then returns to the heart from the pulmonary veins to the left atrium, the left side of the heart.
What gases pass from the blood to the lungs?
blood takes oxygen and gives carbon dioxide to the lungs
What part of the heart receives oxygen blood from the lungs?
The right atrium which passes it to the right ventricle
How many bronchi does your body have?
10 in your right lung and 8 in your left. A total of 18 bronchi.
How is carbon dioxide transported in the lungs?
Carbon dioxide diffuses out of respiring cells into the blood. Part of it is carried by the same protein in red blood cells that carries oxygen-hemoglobin. The blood is carried into the heart, which pumps it into the lungs.
It is medication taken by an inhauler or hand held nebulizer which helps to open up the bronchi to help people who are having a difficult time with breathing. Most frequently seen in Asthma patients.
An organ in a biological context means a group of tissues that perform one or more specific functions. Human lungs meet that criteria, as their purpose is for our respiratory system. Therefore they meet the criteria of a body organ.
What is in the bronchi of the lungs?
two like structures that lead to the lungs and branch off into the broncoe. (trachea)
The two main bronchi are formed when the trachea (or windpipe) divides.
The right bronchus is more vertical than the left. It is also wider and shorter. It is approximately 2.5cm in length and after entering the right lung it divides into three branches (one going to each of the three lobes of the right lung). Each branch then divides into many smaller branches. As the bronchi get smaller, they are called bronchioles. Bronchioles become terminal bronchioles, then respiratory bronchioles, alveolar ducts.. and finally alveoli.
The left bronchus is about 5cm in length and is narrower than the right. After entering the left lung, it divides into two branches (one for each of the two lobes of the left lung). Each branch then divides into smaller bronchi in the same way as the bronchi in the right lung, ending in the alveoli.
The bronchi are lined with ciliated columnar epithelium. This contains cilia which are hair like extensions that propel materials along the airways. This helps to keep the airways clear.
Does emphysema decrease lung volume?
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.
Which lung is bigger--your right or your left?
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.
Why is it important to know someones lung capacity?
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
What does smoking do to the cilia in your lungs?
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).
Why do your lungs inhale and exhale?
As your diaphragm or intercoastal muscles contract the size of the lungs increases. This creates a pressure difference between your lungs and the surrounding atmosphere. By increasing the size of the lungs you create a low pressure environment in the lungs by expanding the same amount of gas to a larger area. this pressure difference doesn't have to be much 1mmhg is more then enough, the main thing is just that you need a difference in preasure. Air flows from high preasure to low preasure, so by decreasing the preasure in the lungs air flows into the lungs. as you breath out you make the lungs smaller by relaxing the muscles and diaphragm, making the volume in the lungs decrease, thus increasing the preasure and moving the air from inside the lungs out to the surrounding atmosphere.
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.
What is the function of the kidney in the excretory system?
