The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
skin breathing passages mouth and stomach barriers providing the first defense white blood cells and inflamitory response second life of defense
White blood cells (WBC) are part of bodies first line of defense against pathogens.
Skin
skin is the first defense.

White blood cells ingest the pathogens to prevent them from harming the human body
The first and biggest line of defense is the skin. This non-discriminatory barrier is also the largest organ of the human body.
The primary boundary is your skin, but almost every organ has some defense against germ infection.

There are several ways to interpret the question. For some, the first line of defence is the skin since it acts as an impermeable barrier and also has antibacterial properties due to the acids secreted and normal bacteria fauna on the skin. However, since most pathogens, being capable of causing disease, can inherently overcome the skin defense, the first line of immune defence is the innate immune system that exists in the tissues underlying epithelia (skin or any mucous membranes). The innate immune system has cells that can recognize and destroy pathogens without specificity.
The skin is the largest organ and forms an effective barrier.
The specific defense system, more commonly the immune system, is the second type of defense system within the body. It's purpose is to comprise a specific defense measure against a pathogen. The specific defense system is not made up of actual organ structures, but it is made up of billions of cells. Thus, the specific defense system is known as a functional system, as opposed to an organ system.
are you against or for organ transplant cause i wanna know its for a science project
The integumentary system (skin) blocks the entrance of pathogens and prevents the loss of water.
An organ transplant can cause tissue rejection, where the patient's immune system tries to destroy the transplanted organ, because the foreign organ is mistaken for pathogens.
