This manual contains in a visual form a school course "Anatomy, physiology and human hygiene" with the basics of medical ecology. Summary tables of characteristics, diagrams and drawings will allow students to quickly repeat the material studied, as well as supplement and expand their knowledge of human biology. Many original schemes, in an accessible and visual form representing the physiology of systems and organs, will allow you to quickly learn information about the physiological processes occurring in the human body. Due to the high level of clarity and accessibility of the material, the manual provides an effective assimilation of the subject and can be used by students as an addition to the main textbook "Human Biology," when preparing homework, in preparation for final and translation exams in biology, in preparation for entrance exams to medical and biological universities, as well as teachers for drawing up lesson notes.
