Aggregate function
Depends on each animal. On humans it seems they have no function except the head hair which has a protective function against heat and cold on the head.
BEcause the form is created to aid a specific function therefore deciding the function for the form. For example the foot, it is formed in a way to aid you walking, circulating blood and more. A foot cannot be forced into protecting the body against diseases, because it was not formed for that particular function.
The function of simple columnar tissue is to provide protection against any bacteria that might be ingested. However, it is still permeable enough for necessary ions to enter.KKK
They're to protect your eyes against chemical splashes or flying objects !
In the context of arthropods the integument refers to the outer covering or cuticle, made from chitin. The arthropod strategy is to have the skeleton on the outside, but it performs the same function as internal skeleton in vertrbrates: to provide a structural framework upon which the organism is built, hence of necessity its proverbial rigidity. To some extent the arthropod skin is also a form of armor against predators; for example the pill-bug may roll up to present only the hard exoskeleton and protect the more vulnerable ventral surface. One might also extend this reasoning to the function of limbs, swimmerets, pincers, etc, each with their own requirement of rigidity to be effective.

It protects the body against disease by producing antibodies that defends the body.

Camouflage is the process of blending into the background. It only works if the predator hunts by looking - animals who hunt by sound or smell are not fooled by camouflage! Many animals have color patterns which match the environment in which they live. If they freeze against this background, they blend in and are harder to see.
Granular leukocytes have multilobed nuclei that function against non specific invading agents in the body. Agranular leukocytes contain a single neuleus not sure about their function...

globulins are the proteins that acts as a antibody against pathogens..
It is used for protection against the outside environment
