- It is a wide, hollow tube that connects the larynx to the bronchi, or airways, of the lungs. Its most vital function is to enable airflow to and from the lungs. The fibroelastic membrane expands and contracts during inhalation and exhalation.

Organs specialized for breathing usually contain moist structures with large surface areas to allow the diffusion of gases.They are also adapted to protect the organism from the invasion of pathogens along those surfaces. In fish, this gas exchange occurs through gills. Some invertebrates, like cockroaches, have simple respiratory systems made of i...
Primary Function
The primary function of the respiratory system is gas exchange. Animal cells use oxygen and produce carbon dioxide as a byproduct. Not only do animals need a way to get more oxygen into the cells, but they also need a way to remove carbon dioxide. The respiratory system provides this functionality. The lungs or gills of an animal remove carbon dioxide while delivering oxygen to the blood. This oxygen is carried to the tissues. The tissues deposit their carbon dioxide waste, which is then carr...
Creating Sounds
While the primary function of the respiratory system is gas exchange, this extensive organ system also has some other roles. In humans and other mammals, the respiratory system is integral creating sounds such as those used for speech. Structures of the upper respiratory tract, especially the larynx, are involved in the production of sound and can modulate pitch, volume, and clarity. Making noises is called phonation.
Olfactory Senses
The nose plays an important role in respiration, but the olfactory nerves and their associated structures are also involved in sensing smell.This has functions ranging from digestion (the cephalic phase of digestion) to hunting, recognition, and mating. Most animals have some sort of olfactory senses, usually in the form of nerves within the respiratory system. Sharks, for instance, can smell blood in the water up to several miles away. Terrestrial predators, like wolves, also use their olfac...
In humans and most mammals, the anatomy of the respiratory system is divided into three parts. The first is the series of conducting tubes that carry air from the atmosphere towards the lungs. The second part consists of the muscles of respiration – the diaphragm and intercostal musclesin the ribs. The lungs form the third part.
The organs described above work as a functional unit within the respiratory system. Air is taken in through the mouth and nose. From here, it makes its way down the trachea. The trachea splits into the bronchi of each lung, where it further divides into a number of smaller tubes that lead to the alveoli. These tiny sacs within the lung are the actu...
Diseases of the respiratory tract can arise due to obstruction to the airway, constriction of the passages, or the loss of the extensive surface area of alveoli for gas exchange. There could also be difficulties with the capillaries surrounding these alveoli, either due to clots or due to altered cardiac function. These illnesses could be chronic c...

Aug 13, 2024 · During swallowing glottis can be covered by a thin elastic cartilaginous flap called epiglottis to prevent the entry of food into the larynx. Trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the level of 5th thoracic vertebra into a right and left primary bronchi.
Aug 29, 2024 · Trachea (Windpipe): A cartilaginous tube that connects the larynx to the bronchi, providing a clear airway for air to enter and exit the lungs. Bronchi and Bronchioles: The trachea divides into two main bronchi (left and right), which enter each lung and branch into smaller bronchioles.
The respiratory system transports oxygen from the air we breathe, through a system of tubes, into our lungs and then diffuses it into the bloodstream, whilst carbon dioxide makes the opposite...
Tube that connects the mouth to the larynx and esophagus. Tube that connects the trachea to the lungs. It is the tiny sac like structure present in the lungs which the gaseous exchange takes place. It is a leaf-shaped flap at the top of the larynx, or voice box.
The respiratory system function is a very important metabolic process in our body that plays a crucial role in all living beings. It begins by breathing and ends by exhalation, that’s the simplest explanation.
