what are the differences between left and right lungs?
156254
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 right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

Why are the lungs NOT perfectly bilateral? The heart is found on the left side of the thorax, and thus the left lung must accommodate the presence of the heart. ... As the thorax expands, its volume increases and air flows into the lungs.

Your Heart is Not on the Left Side of Your Chest Your heart is in middle of your chest, in between your right and left lung. It is, however, tilted slightly to the left.

The right upper lobe of the lung is one of the three lobes that make up the right lung. The lung tissue of this lobe is responsible for most of the gas exchange in the right lung during calm, shallow breathing.

Further, the left ventricle has thicker walls than the right because it needs to pump blood to most of the body while the right ventricle fills only the lungs.

The left lung is a little smaller than the right lung because it shares space in the left side of the chest with the heart.

Gross Anatomy of the Lungs The lungs are pyramid-shaped, paired organs that are connected to the trachea by the right and left bronchi; on the inferior surface, the lungs are bordered by the diaphragm. The diaphragm is the flat, dome-shaped muscle located at the base of the lungs and thoracic cavity.

The right main bronchus is wider, shorter, and more vertical than the left main bronchus, its mean length is 1.09 cm. ... The left main bronchus is smaller in caliber but longer than the right, being 5 cm long. It enters the root of the left lung opposite the sixth thoracic vertebra.

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.

The left side of the heart receives oxygenated blood from the pulmonary vein and pumps it into the aorta, while the right side of the heart receives deoxygenated blood from the vena cava and pumps it into the pulmonary vein.

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.

Chambers of the Heart The right atrium receives blood from the veins and pumps it to the right ventricle. The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.

The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. ... Veins are blood vessels that carry blood from the body to the heart.

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.

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.

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.
