Answer:
<u>A focal infection</u> is a small region of infection, from where the pathogen can move to other areas of the body to cause a secondary infection.
Explanation:
The focal infection theory is a theory that states that many chronic diseases (such as cancer, arthritis, mental illness) are caused by a focal infection. A focal infection is a small region of infection or a localized infected region, which can lead to a secondary infection at a site, which is susceptible to infections. Examples of such focal regions are nasal sinuses, kidney, gall bladder, liver, etc.
<u>Therefore,</u><u> a focal infection </u><u>can be defined as a small region of infection, from where the pathogen can move to other areas of the body to cause a secondary infection</u>.

Organs of excretion make up the excretory system.
They include the :
kidneys-Blood by-products are filtered out by the kidneys and leave the body in urine form. They are part of the urinary system, which also includes the ureters, bladder, and urethra
large intestine-By-products enter the intestine and leave the body in the form of feces
liver- breaks down harmful substances. It's by-products are excreted into bile or blood.
skin-Sweating eliminates excess water and salts, as well as a small amount of urea, a byproduct of protein catabolism
lungs- oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled
