The study of humans behavior is known as Psychology and Sociology.
Self-sacrificing behavior in humans involves individuals putting the needs or well-being of others before their own, often at personal cost or risk. This behavior can be motivated by values like altruism, empathy, duty, or a sense of responsibility towards others. Examples include donating organs, volunteering in risky situations, or making personal sacrifices for loved ones.
