Is sputum from the lower respiratory tract?
Sputum is the thick mucus or phlegm that is expelled from the lower respiratory tract (bronchi and lungs) through coughing; it is not saliva or spit. Care must be taken in the sample collection process to ensure that the sample is from the lower airways and not from the upper respiratory tract.
Where is sputum produced?
Sputum or phlegm is the mucousy substance secreted by cells in the lower airways (bronchi and bronchioles) of the respiratory tract. It differs from saliva, which is produced higher up, in the mouth.
Does sputum come from the lungs?
Sputum is produced when a person’s lungs are diseased or damaged. Sputum is not saliva but the thick mucus – sometimes called phlegm – which is coughed up from the lungs.
What bacteria is found in sputum?
The most common pathogens detected with a sputum culture are bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, and Klebsiella species.
What is the function of mucus in the respiratory tract quizlet?
The function of mucus in the respiratory tract is to destroy microorganisms.
What is the function of mucus in the respiratory tract?
The airway surface liquid (ASL), often referred to as mucus, is a thin layer of fluid covering the luminal surface of the airway. The major function of mucus is to protect the lung through mucociliary clearance against foreign particles and chemicals entering the lung.
How does mucus form in the lungs?
Mucus protects your respiratory system with lubrication and filtration. It’s produced by mucous membranes that run from your nose to your lungs. Every time you breathe in, allergens, viruses, dust, and other debris stick to the mucus, which is then passed out of your system.
What is sputum production mean?
Expectoration or sputum production is the act of coughing up and spitting out the material produced in the respiratory tract.

Which disease is spread by sputum of the patients?
Tuberculosis (TB) is transmitted mainly by droplet infection and droplet nuclei generated by sputum-positive patients with pulmonary TB. Coughing generates the largest number of droplets of all sizes [1]. Thus, its transmission is attributed to indiscriminate disposal of sputum by patients [2,3].
Which of the following comprises the lower respiratory tract?

Where does the sputum come from in the respiratory tract?
Function Sputum or phlegm is the mucousy substance secreted by cells in the lower airways (bronchi and bronchioles) of the respiratory tract. It differs from saliva, which is produced higher up, in the mouth.
When to use sputum microscopy, culture and susceptibility?
Sputum microscopy, culture and susceptibility (MC&S) is used in the detection of a lower respiratory tract infection, usually pneumonia (infection in the lungs). A healthy respiratory tract has a mixture of different bacteria which are harmless and
Is the mucus in your mouth the same as sputum?
Sputum is not the same as saliva, a substance secreted in the mouth to help with digestion. The terms sputum and phlegm are used interchangeably. The term mucus may sometimes be used instead of sputum, but sputum refers to that mucus specifically secreted in the respiratory tract,…
What is the purpose of MC and sputum?
Sputum MC&S – interpretation of results Sputum microscopy, culture and susceptibility (MC&S) is used in the detection of alower respiratory tract infection, usually pneumonia (infection in the lungs). A healthy respiratory tract has a mixture of different bacteria which are harmless anddo not require treatment, this is called colonisation.
