All of the organs and other structures of the upper respiratory tract are involved in the conduction or the movement of air into and out of the body. Upper respiratory tract organs provide a route for air to move between the outside atmosphere and the lungs. They also clean, humidity, and warm the incoming air.Sep 4, 2021
List three functions of the respiratory system. Remove CO2 from the body. Participate in gathering olfactory information. Transport gases from lungs to body cells. Regulate blood pH. Production of CO2 at the cellular level.
There are five functions of the respiratory system.Gas Exchange – oxygen and carbon dioxide.Breathing – movement of air.Sound Production.Olfactory Assistance – sense of smell.Protection – from dust and microbes entering body through mucus production, cilia, and coughing.
What are seven functions of the respiratory system? Move Air: The respiratory system is responsible for moving air to and from exchange surfaces of lungs. ... Produce Sounds: ... Gas Exchange: ...

Respiration consists of 4 distinct processes:Pulmonary Ventilation. moving air into and out of the lungs. ... External Respiration.Transport. transport of oxygen and carbon dioxide between the lungs and tissues.Internal Respiration. diffusion of gases between the blood of the systemic capillaries and cells.
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing.
Serve as an air filter, cleaning the inhaled air, Supply oxygen to body cells, Remove carbon dioxide from the cells, Produce the sounds associated with speech.
The upper respiratory tract includes all the structures through which air passes from the nose and mouth to the trachea. It is responsible for warming and filtering the air inspired in the nose or mouth. Nasal hairs and mucus secreted throughout the respiratory tract trap foreign particles, such as dust, smoke, and pollen. Air passes through the pharynx and then the larynx (voice box) before entering the lower respiratory tract.
Once past the larynx, air moves through the trachea, the main bronchi, and down a smaller series of bronchioles where it reaches the alveoli. The exchange of oxygen and carbon dioxide takes place in the alveolar capillaries. The lungs are lined with visceral pleura and the thoracic cavity is lined with parietal pleura. The space between both pleural membranes is the pleural cavity, which is filled with a fluid that cushions the lungs for easy expansion during respiration.
The zoonotic disease Q fever is caused by a rickettsia, Coxiella burnetii. The primary reservoirs for this bacterium are domesticated livestock such as cattle, sheep, and goats. The bacterium may be transmitted by ticks or through exposure to the urine, feces, milk, or amniotic fluid of an infected animal. In humans, the primary route of infection is through inhalation of contaminated farmyard aerosols. It is, therefore, largely an occupational disease of farmers. Humans are acutely sensitive to C. burnetii —the infective dose is estimated to be just a few cells. [12] In addition, the organism is hardy and can survive in a dry environment for an extended time. Symptoms associated with acute Q fever include high fever, headache, coughing, pneumonia, and general malaise. In a small number of patients (less than 5%), [13] the condition may become chronic, often leading to endocarditis, which may be fatal.
S. pyogenes is the sole member of the Lancefield group A streptococci and is often referred to as GAS, or group A strep. Similar to streptococcal infections of the skin, the mucosal membranes of the pharynx are damaged by the release of a variety of exoenzymes and exotoxins by this extracellular pathogen.
Psittacosis is a relatively rare infection and is typically found in people who work with birds. Chlamydia trachomatis, the causative agent of the sexually transmitted disease chlamydia, can cause pneumonia in infants when the infection is passed from mother to baby during birth.
