how are the lungs designed in human beings to minimise the area for?

The alveoli provide a surface where the exchange of gases can take place. ... The walls of the alveoli are supplied with an extensive network of blood vessels. So lungs maximise the area for gaseous exchange through the presence of large number of alveoli which are richly supplied with blood.

The lungs are located within the chest cavity, most of which is contained within the rib cage.

Your lungs are one of the largest organs in your body. The surface area of both lungs is roughly the same size as a tennis court and the total length of the airways running through them is 1,500 miles.

The left lung is smaller because of the space taken up by the heart (see diaphragm for an image of this). Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes. ... The lungs are "stuck" to the inside of the thorax, also by surface tension.

The lungs are the primary organs of the respiratory system in humans and many other animals including a few fish and some snails. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart.

Lungs. The lungs are located on either side of the breastbone in the chest cavity and are divided into five main sections (lobes). The lungs are responsible for removing carbon dioxide from the blood and adding oxygen to it.

Bronchioles and alveoli in the lungs. In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways — the smallest, called bronchioles, lead to tiny air sacs (alveoli).

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, which shares space in the chest with the heart. The lungs together weigh approximately 1.3 kilograms (2.9 lb), and the right is heavier.

Together, the lungs contain approximately 2,400 kilometres (1,500 mi) of airways and 300 to 500 million alveoli. Each lung is enclosed within a pleural sac that contains pleural fluid, which allows the inner and outer walls to slide over each other whilst breathing takes place, without much friction.

Secretion is Accumulated in the Lungs When the client is halfway lying and halfway sitting in this position, gravity will push the secretion from the lungs down to the bottom of the lung tissue allowing the client to breathe more easily because he/she is only using the top half of the lungs.

The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out. When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward.

Lungs are divided into a smaller structure called bronchi which are divided into bronchioles. Alveoli are small, round or balloon-like structure found the end of the bronchioles and provide a larger surface area and maximizes the exchange of gases inside the lungs.

The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they give the lungs a really big surface area. they have moist, thin walls (just one cell thick)

Seen from either side, the lung is here. A large part of each lung lies behind the heart. The lung extends from the ribs in front, to the ribs behind, and from the dome of the pleural cavity, down to the diaphragm. With each breath in, and each breath out there's an increase and a decrease in the volume of the lungs.
