Oct 30, 2023 · The respiratory system, also called the pulmonary system, consists of several organs that function as a whole to oxygenate the body through the process of respiration (breathing). This process involves inhaling air and conducting it to the lungs where gas exchange occurs, in which oxygen is extracted from the air, and carbon dioxide expelled ...

Sep 21, 2023 · The respiratory system is not just a series of tubes and sacs but an intricately coordinated system that provides the very essence of life: the ability to breathe. With each inhalation and exhalation, it performs a delicate balancing act, maintaining the intricate chemistry that sustains human life.
Feb 28, 2024 · Respiratory system diagram. Lower respiratory tract organs. Trachea: Also known as the windpipe this is the tube that carries air from the throat into the lungs. It ranges from 20-25mm in diameter and 10-16cm in length.
Oct 21, 2023 · The diagram of the human respiratory system illustrates the organs and structures responsible for breathing. It typically includes the nasal cavity, trachea, bronchi, and lungs. Inhaling air through the nose, travels down the trachea, branching into the bronchi, and finally reaching the lungs.

Structure
There are two lungs (a right and left) in the body, but they are different sizes. The right lung is bigger and is divided into three lobes (separated by fissures), while the left lobe is smaller consisting of two lobes. The left lobe is also smaller as it has to make room for the heart. The left and right lungs are suspended by the lung root and separated by a mediastinum, a partition between the two. Each lung has three surfaces, named after their location in the thorax. They are the mediast...
Location
The lungs are guarded by the rib cage, and they are located right above the diaphragm. Each lung is located near different organs in the body. The left lung lies close to the heart, thoracic aorta, and esophagus, while the right lung is by the esophagus, heart, both vena cavas (inferiorand superior), and the azygos vein. Looking at the lungs from the front they lie right above the collarbone and go halfway down the rib cage, although the back of the lungs are slightly longer, ending just abov...
Anatomical Variations
It’s common to see anatomical variations when it comes to the lungs. For example, in one study of 50 cadavers, 26% had incomplete and absent fissures, extra lobes, and/or an azygos lobe (when the azygos vein creates an extra fissure in the right lobe). While these anatomical variations are common and often go unnoticed in otherwise healthy individuals, it’s important to distinguish them when reading radiological images as well as ahead of any surgery involving the lungs and monitoring for any...
The lungs are responsible for bringing in fresh air into the body. As you breathe in the diaphragm helps move air up into the lungs by tightening its muscles (relaxing pushes air out). Once air enters the lungs by way of the mouth and nose (with the help of mucuswhich traps dust and dirt from entering with the air), the air travels through the trac...
Lung disease is an extremely broad term, as it covers a plethora of conditions ranging from mild to severe. The three main types of lung disease include: 1. Airway diseases including chronic obstructive pulmonary disease (COPD), and asthma. COPD affects 65 million people and is the third leading cause of death worldwide. Asthma affects 334 million ...
Your lung function hits max capacity between the ages of 20 to 25 years old, but after age 35 it naturally (and slightly) declines.However, difficulty breathing or shortness of breath is not normal and should be discussed with your healthcare provider immediately. After discussing your symptoms along with your overall health history, your healthcar...
