What are lung diseases?

Intricate Construction Our two lungs are made up of a complex latticework of tubes, which are suspended, on either side of the heart, inside the chest cavity on a framework of elastic fibers. Air is drawn in via the mouth and the nose, the latter acting as an air filter by trapping dust particles on its hairs.
What is called mediastinum?mediastinum, the anatomic region located between the lungs that contains all the principal tissues and organs of the chest except the lungs. … The mediastinum is a division of the thoracic cavity; it contains the heart, thymus gland, portions of the esophagus and trachea, and other structures.

What is the main function of the lungs?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

How many lungs do humans have?
You have two lungs, the left lung and the right lung. The left lung is slightly smaller and has a notch to give room for the heart. Each lung is divided into lobes—the left lung has two and the right lung has three—which are similar to balloons filled with sponge-like tissue.

Most people can get by with only one lung instead of two, if needed. Usually, one lung can provide enough oxygen and remove enough carbon dioxide, unless the other lung is damaged. During a pneumonectomy, the surgeon makes a cut (incision) on the side of your body.
How large is a human lung?
In the normal adult, the lungs weigh approximately 1000 g. Lung volume increases from about 250 mL at birth to 6000 mL in the adult. The height of a normal adult lung is 27 cm at total lung capacity, but in the range of normal breathing it is approximately 24 cm in height.
What is inside a lung?
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). … In the alveoli, oxygen from the air is absorbed into the blood. Carbon dioxide, a waste product of metabolism, travels from the blood to the alveoli, where it can be exhaled.
Why is the left lung smaller?
Locate Those Lungs You have two lungs, but they aren’t the same size the way your eyes or nostrils are. Instead, the lung on the left side of your body is a bit smaller than the lung on the right. This extra space on the left leaves room for your heart.

Middle: The middle mediastinum is the largest portion, and contains the heart, blood vessels including those that travel from the lungs to the heart, and lymph nodes.
What organ is posterior to the heart?

- Drenching night sweats.
- Weight loss without trying.
- Itching skin.
- Feeling tired.
- Loss of appetite.
Can hilar lymph nodes be removed?
The interlobar lymph nodes and hilar lymph nodes around the vessels should not be removed separately; rather, they should be dissociated to the distal end of the vessel and then removed en bloc with the right upper pulmonary lobe. This is more consistent with the principles of surgical oncology.
