Heart/Lung

image of heart and lung

The aorta is the main artery that carries blood from the heart to all parts of the body except the lungs. The pulmonary artery is one of the two arteries that carry blood from the heart to the lungs. The vena cava is either of two large veins that return blood to the right atrium of the heart. The left atrium is the upper left chamber of the heart that receives blood from the pulmonary veins. The right atrium is the upper right chamber of the heart that receives blood from another part of the body and pumps it into a ventricle. The septum is the muscle wall that divides the heart into chambers. The left ventricle is the largest and most muscular chamber of the heart that pumps oxygen-rich blood from the lungs to the rest of the body. The right ventricle is the chamber on the right side of the heart that receives blood from the right atrium and pumps it to the arteries.

Also called the windpipe, the trachea is the tube that connects your mouth and nose to your lungs. The primary bronchus transports air to and from the lungs. The right lung is larger than the left and contains the upper, middle and lower lobes. The left lung contains two lobes, the upper and lower lobe. The alveoli are tiny air sacs located in the lungs.

Functions of the Heart/Lung

The heart is a strong and muscular, cone-shaped organ that is about the size of a fist. It pumps blood throughout the body and is located behind the breastbone between the lungs. Deoxygenated blood flows from the heart to the lungs where it gives up wastes and is freshly oxygenated. From there, the blood returns to the heart and is pumped to the rest of the body. Heart failure is the inability of the heart to pump enough blood to maintain normal body requirements. Birth defects or any condition that damages or overloads the heart muscle can cause it. Treatment depends on the cause of heart failure and the age and condition of the patient.

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 lungs are divided into lobes, with three on the right and two on the left.

Heart/Lung Transplant Procedures

Heart/lung transplants generally involve the transplantation of two lungs with the heart. There have been very few heart/lung transplants performed using only one lung.
