Respiratory Tract Neoplasms are defined as abnormal growths or tumors that develop within the respiratory system, including the nose, sinuses, throat (pharynx), voice box (larynx), windpipe (trachea), bronchi, and lungs, which can be benign or malignant, with the potential to cause significant morbidity and mortality.
Tumors or cancer in the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.
Invasion of the host RESPIRATORY SYSTEM by microorganisms, usually leading to pathological processes or diseases.
The tubular and cavernous organs and structures, by means of which pulmonary ventilation and gas exchange between ambient air and the blood are brought about.
Respiratory tract diseases are a broad range of medical conditions that affect the nose, throat, windpipe, and lungs, impairing breathing and oxygen uptake, including asthma, chronic obstructive pulmonary disease (COPD), pneumonia, bronchitis, influenza, tuberculosis, and sleep apnea.
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Inflammatory responses of the epithelium of the URINARY TRACT to microbial invasions. They are often bacterial infections with associated BACTERIURIA and PYURIA.
New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
Infections with viruses of the family PARAMYXOVIRIDAE. This includes MORBILLIVIRUS INFECTIONS; RESPIROVIRUS INFECTIONS; PNEUMOVIRUS INFECTIONS; HENIPAVIRUS INFECTIONS; AVULAVIRUS INFECTIONS; and RUBULAVIRUS INFECTIONS.
Substances that reduce the growth or reproduction of BACTERIA.
Pneumovirus infections caused by the RESPIRATORY SYNCYTIAL VIRUSES. Humans and cattle are most affected but infections in goats and sheep have been reported.
The top portion of the pharynx situated posterior to the nose and superior to the SOFT PALATE. The nasopharynx is the posterior extension of the nasal cavities and has a respiratory function.
A group of viruses in the PNEUMOVIRUS genus causing respiratory infections in various mammals. Humans and cattle are most affected but infections in goats and sheep have also been reported.
Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.
The cartilaginous and membranous tube descending from the larynx and branching into the right and left main bronchi.
A genus of the subfamily PNEUMOVIRINAE, containing two members: Turkey rhinotracheitis virus and a human Metapneumovirus. Virions lack HEMAGGLUTININ and NEURAMINIDASE.
