Carbon-14 enters the body primarily through the consumption of organic materials, such as plants and animals, that have absorbed carbon dioxide from the atmosphere. As plants photosynthesize, they incorporate carbon-14, and when animals eat these plants, the isotope is transferred up the food chain. Additionally, carbon-14 can also be inhaled when breathing in atmospheric carbon dioxide. This natural process keeps the levels of carbon-14 relatively constant in living organisms.

White blood cells are the part of blood that fights germs that enter the body. They recognize and attack harmful pathogens to help keep the body healthy.
they enter the bloodstream. when you get cut for example, the capillaries are broken, so there, the pathogens enter.
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
