- The human lungs are a pair of large, spongy organs optimized for gas exchange between our blood and the air. Our bodies require oxygen in order to survive. The lungs provide us with that vital oxygen while also removing carbon dioxide before it can reach hazardous levels.lveoli are the functional units of the lungs that permit gas exchange between the air in the lungs and the blood in the capillaries of the lungs. Alveoli are found in small clusters called alveolar sacs at the end of the terminal bronchiole.

- In this way, our lungs play a vital role in providing oxygen to all the parts of our body. It is important for our bodies to get rid of carbon dioxide which is produced as a waste product of respiration. Once again, lungs are the organs which help in the elimination of this toxic waste product.

Symptoms of Lung Disorders Chronic lung conditions such as asthma, COPD, and interstitial lung disease may wax and wane in severity and can worsen quickly and markedly if another problem, such as a lung infection, occurs. Common symptoms of lung disorders include shortness of breath, coughing, noisy breathing, and chest pain. Some people, however, have only mild symptoms or none at all. In these individuals, the disorder may be detected by a physical examination, on a chest x-ray, or by a test to check lung function.

- Used in yards, farms and parks throughout the world, Roundup has long been a top-selling weed killer. But now researchers have found that one of Roundup’s inert ingredients can kill human cells, particularly embryonic, placental and umbilical cord cells.onsanto, Roundup’s manufacturer, contends that the methods used in the study don’t reflect realistic conditions and that their product, which has been sold since the 1970s, is safe when used as directed.

EBME & Clinical Engineering Articles The lungs consist of two cone shaped spongy organs that contain alveoli and trap air for gas exchange. The lung is designed for gas exchange. Its prime function is to allow oxygen to move from the air into the venous blood and carbon dioxide to move out. Although the lung performs other functions, its primary responsibility is to exchange gas.

lung (lŭng) 1. Either of two spongy organs in the chest of air-breathing vertebrate animals that serve as the organs of gas exchange. Blood flowing through the lungs picks up oxygen from inhaled air and releases carbon dioxide, which is exhaled. Air enters and leaves the lungs through the bronchial tubes.

- Symptoms of the lung involve changes in breathing, coughing, or pain in the chest. Breathing symptoms include dyspnea (difficulty breathing), tachypnea (rapid breathing), hypopnea (shallow breathing), hyperpnea (deep breathing), and apnea (absence of breathing).nxiety and panic attacks are also common causes of lung symptoms and include rapid breathing that may result in hyperventilation or fainting. Airway obstruction causes lung symptoms that may include rapid shallow breathing. Lung injury from chest trauma can lead to breathing symptoms.

- In humans and other mammals, the anatomical features of the respiratory system include trachea, bronchi, bronchioles, lungs, and diaphragm. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood.ee also: Respiratory tract. The respiratory system (called also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism.

- Here is a list of the changes that happen in your lungs and airways when you smoke: 1  The cells that produce mucus in your lungs and airways grow in size and number. As a result, the amount of mucus increases. 2  The cleaning system in your lungs does not work well. The lungs have broom-like hairs, called cilia (SILL-ee-uh).

- We can think of symptoms as the subjective aspect of illness and signs as the objective aspect. Both are important in diagnosing and treating any illness, especially lung disease. The most common symptoms of lung disease are: Cough. shortness of breath (either at rest or on exertion), also known as dyspnea.

Lung The lungs are the primary organs of respiration in humans and many other animals. Humans have two lungs, a right lung and a left lung. They are situated within the thoracic cavity of the chest. The right lung is bigger than the left lung, as the left lung shares space in the chest with the heart. The lungs together weigh approximately 1.3 kilograms (2.9 lb), with the right lung weighing more than the left.

- The lungs are a pair of elastic, spongy organs used in breathing. In humans the lungs take up a lot of the chest cavity. They are located just behind, and to either side of, the heart. They extend down from the collarbone to the diaphragm (the muscular wall between the chest cavity and the abdominal cavity).

Lung The lungs are part of the lower respiratory tract, and accommodate the bronchial airways when they branch from the trachea. The lungs include the bronchial airways that terminate in alveoli, the lung tissue in between, and veins, arteries, nerves and lymphatic vessels. The trachea and bronchi have plexuses of lymph capillaries in their mucosa and submucosa.

Lung Each lung consists of: 1  Apex – The blunt superior end of the lung. It projects upwards, above the level of the 1st rib and into the floor of the neck. 2  Base – The inferior surface of the lung, which sits on the diaphragm. 3  Lobes (two or three) – These are separated by fissures within the lung.

Lung The cone-shaped lungs are sponge-like organs that fill the chest cavity and make up most of the lower respiratory tract. Their most important job is providing oxygen to capillaries so they can oxygenate blood. Each lung is divided into lobes. The right lung has three, but the left lung has only two, thus allowing room to accommodate the heart. Together, the lungs’ tissue surface is almost 40 times greater than the body’s outer surface, making the lungs (together) one of the largest organs in the body.
