Introduction     The human lung is the organ that provides us with oxygen and removes carbon dioxide from our bodies. It's one of the most important organs in our body, but it's also one of the least understood. In this article, we'll explore in detail exactly how your lungs work and what happens when they don't do their job properly. Overview of the Human Lung      The lungs are a pair of organs that sit in the chest cavity. They are the primary site of gas exchange between the body and the environment, taking oxygen from inhaled air and releasing carbon dioxide to be exhaled. The human lung consists of many different structures that work together to perform this function. The Lobar Structure of the Lungs      The lungs are divided into lobes. On the right side, there are three lobes: an apical (top), middle and basal (bottom). On the left side, there are two lobes: an apical and a basal.      The right upper lobe is smaller than i...

       Imagine for a moment that you could take a clear, in-depth look at the anatomy of the human heart. What would you see? In this article, we'll explore the structure and function of the human heart in detail. We'll start by looking at the heart's basic anatomy including its four chambers, valves, and coronary arteries. We'll also take a closer look at the heart's electrical system, including the sinus node and atrial and ventricular muscles. Finally, we'll discuss some of the common heart diseases and conditions. Overview of the Human Heart The human heart is an amazing organ that is responsible for pumping blood throughout the body. It is made up of four chambers: the right atrium, the right ventricle, the left atrium, and the left ventricle. The heart also has four valves: the tricuspid valve, the pulmonary valve, the aortic valve, and the mitral valve. These valves are open and close to control the flow of blood in and out of the heart. The heart is a mu...
