Latest Respiratory system Stories
Scarring of the airways can lead to long-term breathing problems for some people exposed to high levels of chlorine gas from events such as an industrial accident, chemical spill following a train derailment or terroristic chemical warfare.
Respiratory conditions that restrict breathing such as asthma and chronic obstructive pulmonary disease (COPD) are common killers worldwide.
Mucus coats our airways' internal surfaces. The viscous gel humidifies the lungs and prevents viruses and other small particles like diesel soot from entering the body unchecked.
Amidst the extraordinarily dense network of pathways in a mammal lung is a common destination. There, any road leads to a cul-de-sac of sorts called the pulmonary acinus. This place looks like a bunch of grapes attached to a stem (acinus means “berry” in Latin).
Researchers recently published a study on their work to understand how human lungs clean out mucus from colds and allergy, making the airways free to foreign matter that may be toxic or infectious to the body.
New data released by the Forum of International Respiratory Societies (FIRS) to coincide with World Spirometry Day today has revealed a worrying lack of understanding and concern among the public about the world's biggest killer - lung disease, which now claims the lives of almost 4 million people a year.
The development of convenient, yet physiologically relevant in vitro culture systems is critical to research and development on chronic respiratory diseases such as asthma or COPD, and could accelerate
Cystic fibrosis, also called mucoviscidosis, is an autosomal recessive genetic disorder of the viscous secretions in the body. In turn, it effects the lungs, pancreas, liver, and intestines, as well as all other exocrine glands in the body. The most common genetic mutation that causes CF is a deletion of three nucleotides that results in a loss of phenylalanine, an amino acid at the 508th position on the protein. It should be noted, however, that there are over a thousand other mutations that...
The pharynx is situated directly after the mouth and nose and lies right before the esophagus. Formation and Orientation The pharynx is divided into three separate sections. The nasopharynx is the first part of the pharynx that lies between the soft palate and the base of the skull. The pharyngeal tonsils are located on the back wall of the nasopharynx. This portion of the pharynx is connected to the middle easr by the Eustachian tubes. The nasopharynx is linked to the nasal cavities...
The trachea, commonly called the windpipe, is the air passage-way from the mouth to the lungs. Non-fish vertebrae all have a trachea. The moist with mucus walls of the tube-like structure trap inhaled particles to keep them from entering the lungs. Structure The trachea is an open-ended cylindrical structure that starts at the larynx and ends at the bifurcation. It is about one inch in diameter and can run four to six inches in length. Within the pipe there are anywhere from 15 to 20...
The lung is a vital organ that is a part of the respiratory system. Generally a person has two lungs; however, the body can function with only one. The lung’s main function is to move oxygen and carbon dioxide into and out of the bloodstream through gas exchange. The lungs are located lateral to the heart in the thoracic cavity. Each lung has a tip called the apex, which is superior in the body. The bases of the lungs rest on the diaphragm. They appear to be spongy due to their bundles of...
