what is the primary structural difference between the right and left lungs?

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.

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. The heart and lungs work together to do this.

Humans breathe exclusively through their lungs, but frogs use their lungs for only part of their respiration. Frog lungs have thinner walls and are almost like balloons. ... Both species have bronchial tubes leading to the lungs, but human systems are more complicated, with many branching bronchiole.

A chest X-ray helps detect problems with your heart and lungs. The chest X-ray on the left is normal. The image on the right shows a mass in the right lung. Chest X-rays produce images of your heart, lungs, blood vessels, airways, and the bones of your chest and spine.

Known as pulmonary hypertension, the condition affects both the lungs and the heart. The right side of the heart works harder to pump blood to the lungs. At the same time, damage to the small vessels within the lungs means less oxygen reaches the blood.

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.

Locate Those Lungs Your lungs are in your chest, and are so big that they take up most of the space in there. 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.

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.

Lungs are a pair of highly elastic and spongy organs in the chest. They are the main organs involved in breathing. They take in air from the atmosphere and provide a place for oxygen to enter the blood and for carbon dioxide to leave the blood.

Lung function. The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.

The right atrium receives deoxygenated blood from the systemic circulation via the superior and inferior vena cava. On the other hand, oxygenated blood leaving the lungs is carried to the left atrium via the pulmonary veins.

The left ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.

All mammals have lungs that are the main organs for breathing. Lung capacity has evolved to support the animal's activities. During inhalation, the lungs expand with air and oxygen diffuses across the lung's surface, entering the bloodstream. During exhalation, the lungs expel air and lung volume decreases.

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.

The lungs are conical in shape with a rounded point at their apex and a flat base that rests on the convex surface of the diaphragm. The lungs are located in the thoracic cavity extending anteriorly and laterally from the heart to the ribs and posteriorly to the thoracic spine.

The root of the lung is the collection of structures that connect the lung to the mediastinum. This includes the pulmonary arteries and veins, the primary bronchi and bronchial arteries, and the pulmonary nerve plexuses and lymphatics. The hilum is the place on the lung where these structures enter and leave the lung.

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.
