The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
When a pathogen (disease-causing organism) invades the body, the neutrophils gather at the entry site and try to engulf it and destroy it.
A T helper cell will recognise only one pathogen. If the T helper cell recognises the invader, it will immediately clone to increase numbers.
After a few days of fighting off the pathogen, you will recover from your infection.

Adenomatous polyposis coli is known as APC. An individual has a higher lifetime chance of developing many colorectal polyps (from ten to hundreds) as well as colorectal cancer if they have a genetic mutation that interferes with the operation of the APC gene. Colon cancer can strike anyone at any age, but it often strikes older persons. Small, benign (noncancerous) cell clusters called polyps commonly grow on the interior of the colon as the first signs of the condition. Some of these polyps may eventually develop into colon cancer.
