Pathology has been defined as "that branch of medicine which treats of the essential nature of disease."

Pathologists are experts at interpreting microscopic views of body tissues. Typical examples include cervical smear, sputum and gastric washings. Forensic pathology involves the post mortem examination of a corpse for cause of death using a process called autopsy. Dermatopathology concerns the study of skin diseases.

What is the affect to barometer during cyclone

Posted by Naman Chotia 7 years, 5 months ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 5 years, 7 months ago

Barometric pressure is the weight of the atmosphere that surrounds us. Barometric pressure often drops before bad weather. Lower air pressure pushes less against the body, allowing tissues to expand. Expanded tissues can put pressure on joints and cause pain. Low-pressure systems generally produce high winds, warmer air, and atmospheric lift— ideal ingredients for a tropical storm. The lower the barometric pressure in hurricanes, the higher the wind speeds— and the more dangerous the storm.

Protozoa are one-celled organisms that can cause diseases ranging in severity from mild to deadly. These organisms can be classified as parasitic or free-living. Parasitic protozoa are found in organisms such as ticks, flies and mosquitoes. Example: Malaria. Malaria is carried by an infected mosquito. Free-living protozoa are found in water that is contaminated with fecal matter and other wastes. Example: Amoebiasis. Amoebiasis is a protozoan disease caused by Entamoeba histolytica. This infection is spread by contact with feces, which can occur if water or food is contaminated.
