Human Body

Sub Sections: — Anatomy and Physiology — Health and Diseases

The Human Body section focuses on the organization, functioning, and integration of the biological systems that make up the human organism. It is a systemic and physiological approach to understanding the complexity of the human body, analyzed at multiple levels: molecular, cellular, tissue, organic, and systemic.

Topics covered include:

• Structural organization : levels of biological organization, from tissues to systems, with a focus on functional architecture and histology;
• Physiological systems : structure and function of the major systems (nervous, endocrine, cardiovascular, respiratory, digestive, excretory, muscular, immune and reproductive);
• Homeostasis and regulation : neuro-endocrine control mechanisms, negative and positive feedback, physiological adaptations;
• Cellular communication and systemic integration : hormones, neurotransmitters, receptors and molecular signals;
• Development and differentiation : human embryogenesis, organogenesis and aging;
• Basic pathophysiology : introduction to the main imbalances and functional alterations that lead to pathological conditions.

The scientific study of the human body allows us to understand not only normal physiology, but also the biological basis of disease and therapeutic interventions, constituting an essential foundation for medical sciences, applied biology and the health professions.
