The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.
Abdominal thrusts anti-choking technique: Embrace the victim's abdomen from behind and then apply strong compressions on the area located between the chest and the belly button. Abdominal thrusts [37] are performed with the rescuer embracing the belly of the choking victim from behind. Then, the rescuer closes their own dominant hand, grasps it ...
In addition, the liver, pancreas, and biliary apparatus develop as outgrowths of the endodermal epithelium of the upper part of the duodenum. Since the upper part of the foregut is divided by the tracheoesophageal septum into the esophagus posteriorly and the trachea and lung buds anteriorly, deviation of the septum may result in abnormal ...
The liver synthesises the bulk of lipoproteins. The liver is located in the upper right quadrant of the abdomen and below the diaphragm to which it is attached at one part, the bare area of the liver. This is to the right of the stomach and it overlies the gall bladder. The liver synthesises bile acids and lecithin to promote the digestion of ...
The throat's trachea carries inhaled air to the bronchi of the lungs. The esophagus carries food through the throat to the stomach. [5] Adenoids and tonsils help prevent infection and are composed of lymph tissue. The larynx contains vocal cords, the epiglottis (preventing food/liquid inhalation), and an area known as the subglottic larynx, in ...
An organ system is a biological system consisting of a group of organs that work together to perform one or more functions. [1] Each organ has a specialized role in an organism body, and is made up of distinct tissues.
The laryngotracheal groove is a precursor for the larynx and trachea. The rudiment of the respiratory organs appears as a median longitudinal groove in the ventral wall of the pharynx . The groove deepens, and its lips fuse to form a septum, which grows from below upward and converts the groove into a tube, the laryngotracheal tube .
The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus . The bronchi branch off into smaller sections inside the lungs, called bronchioles .
