Thanks

Please and thank you.
The answer is A. integumentary system
You are correct, the immune system relies on the integumentary system to provide the first line of defense against pathogens. To arrive at this answer, let's take a closer look at each option:
A. Integumentary system: The integumentary system consists of the skin, hair, and nails. The skin acts as a physical barrier against pathogens, preventing them from entering the body.
B. Nervous system: The nervous system is responsible for coordinating the body's responses to stimuli but does not play a direct role in the immune system's first-line defense against pathogens.
C. Circulatory system: The circulatory system, mainly composed of the heart, blood vessels, and blood, transports nutrients, oxygen, and immune cells throughout the body. While it is critical for the immune system's overall function, it does not specifically provide the first line of defense.
D. Endocrine system: The endocrine system produces hormones that regulate various bodily functions. Although hormones can influence the immune system, the endocrine system does not directly contribute to the first line of defense.
Thus, among the given options, the correct answer is A. Integumentary system.
I disagree.
Be sure you understand the functions of each of those systems.
