are the lungs medial or lateral?
10441
The lungs lie lateral to the heart. Towards the mid line of the body. The heart lies medial to the lungs.

The lungs are not equal in size. ... 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 alveoli are the functional units of the lungs and they form the site of gaseous exchange.

In humans, a pair of lungs are designed in such a way that they are lined by a thin membrane, the smaller tubes called bronchioles a balloon-like structure called alveoli and network of blood capillaries increase the surface area for exchange of gases.

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.

A pulmonary alveolus (plural: alveoli, from Latin alveolus, "little cavity") is a hollow cup-shaped cavity found in the lung parenchyma where gas exchange takes place. Lung alveoli are found in the acini at the beginning of the respiratory zone. ... Different structures are involved in gas exchange in other vertebrates.

Medial and Lateral This is the midline. Medial means towards the midline, lateral means away from the midline. ... The nose is medial to the ears.

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.
441730
The lungs are located on the outside of the thoracic cavity.

Where are the lungs found? The lungs are found in the chest on the right and left side. At the front they extend from just above the collarbone (clavicle) at the top of the chest to about the sixth rib down. At the back of the chest the lungs finish around the tenth rib.

The right main bronchus subdivides into three secondary bronchi (also known as lobar bronchi), which deliver oxygen to the three lobes of the right lung—the superior, middle and inferior lobe. The azygos vein arches over it from behind; and the right pulmonary artery lies at first below and then in front of it.

Lungs are a pair of respiratory organs situated in a thoracic cavity. Right and left lung are separated by the mediastinum. Lies above the level of anterior end of 1st Rib. Reaches 1-2 cm above medial 1/3rd of clavicle.

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

A lateral orientation is a position away from the midline of the body. For instance, the arms are lateral to the chest, and the ears are lateral to the head. ... An example of medial orientation is the eyes, which are medial to the ears on the head.

Lung tissue consists mainly of alveoli (Figure 16.2. 6). These tiny air sacs are the functional units of the lungs where gas exchange takes place. The two lungs may contain as many as 700 million alveoli, providing a huge total surface area for gas exchange to take place.
