a
Protect your body from harmful substances and infection
b
Protect our bodies from harmful substances, senses temperature and pain, regulates body temperature, and removes wastes
c
Transport materials such as nutrients, hormones, and water throughout the body
d

1. The function of the Integumentary System is to protect the bodies from harmful substances, senses temperature and pain, regulates body temperature, and removes wastes (b).

2. The function of the Immune System is protect the body from harmful substances and infection (a).

Explanation:

The integumentary system includes the skin and skin annexes. The skin covers the entire body and therefore provides protection, avoiding contact with harmful agents and acting as a barrier that protects the internal tissues. Other functions of the skin include

The immune system is made up of a group of cells —neutrophils and lymphocytes— and substances that are responsible for protecting the body.

This system is capable of identifying and eliminating any harmful or infectious agent -such as bacteria, viruses, parasites and fungi- through cellular or humoral action, the latter including antibodies and cytokines.

The other options, for both systems, are not correct because:

    C. The transport of nutrients, hormones and water throughout the body is a function of the circulatory system.

    D. Breaking down food to obtain molecules that can be absorbed is a function of the digestive system.
