Lymphocytes, also known as white blood cells or warrior cells, are a type of immune cell that are responsible for fighting infection. They are the most abundant type of white blood cell and are divided into two main types: B-cells and T-cells. B-cells make antibodies that recognize and attack foreign invaders, while T-cells directly attack …

Fever is a natural defence mechanism that the body uses to fight off viruses and bacteria. It is caused by the release of certain hormones, such as interleukin-1 and tumor necrosis factor, which increase the body’s temperature. This higher temperature makes it more difficult for viruses and bacteria to survive and reproduce in the body, …

The healing of wounds after blood clotting is a complex process that involves several stages. Initially, the clotting process stops the bleeding, and the wound is protected by the formation of a scab. The wound is then cleansed and any debris or foreign objects are removed. The body’s immune system responds to the wound and …
Blood clotting is a process that helps to stop bleeding when a blood vessel is injured. It is a complex process that involves multiple steps. First, platelets gather at the site of the injury and release substances that cause the blood to thicken and form a clot. Then, proteins in the blood, including fibrin, interact …
Phagocytosis is a process by which cells, usually white blood cells, engulf and absorb foreign particles, such as bacteria and viruses. This process is part of the innate immune response, which helps defend the body from infection and disease. During phagocytosis, the phagocytes, or white blood cells, first recognize a foreign particle, and then engulf …
White blood cells play a major role in the inflammatory response. They help to recognize and eliminate pathogens, and they also produce a variety of molecules that help to regulate the inflammatory response. These molecules include cytokines, chemokines, and other signalling molecules. White blood cells also help to remove dead cells and debris from the …
The major advantage of dilation of capillaries at the wound site is that it increases blood flow to the area, which helps to speed up the healing process. This increased circulation helps to deliver oxygen and nutrients to the wound site, which in turn helps to promote tissue regeneration. Additionally, dilated capillaries help to reduce …
The inflammatory response is a reaction of the body’s immune system to injury or infection. It is the body’s way of protecting itself from foreign invaders such as bacteria or viruses. The inflammatory response involves the release of chemicals and other substances that help fight infection and repair tissue damage. This response can cause redness, …
White blood cells, also known as leukocytes, are a vital part of the body’s immune system. They are responsible for defending the body against infection and disease. There are several types of white blood cells, including lymphocytes, neutrophils, eosinophils, basophils, and monocytes. Each type of white blood cell has a specific function that helps protect …
