Hi. You have not informed the institutions to which your question refers, which makes it impossible for this question to be answered. however, I will try to help you as best I can.
Generally speaking, we can affirm that human rights are the basic rights that protect the dignity of human beings and must be distributed equally to all. There are some institutions that work directly with these rights and have very important functions to protect them. To find out what the specific functions of each institution are, and thus answer your question, you need to search for each one of them. A quick internet search should be enough to present the information you need. Below, I will list some of the most important institutions and their role in protecting human rights, I hope this can help you.
UNESCO: Is responsible for promoting peace and encouraging the provision of education, culture and communication to under-resourced communities.
WHO: Its responsibility is to promote international cooperation to provide better levels of health to all countries in an equitable and efficient manner.
International Labor Organization: Protects labor rights and promotes the opening of international jobs.
