Human anatomy or anthropotomy is a special field within anatomy. It studies organs and organ systems of the human body, leaving the study of tissues to histology and cells to cytology. The human body, like the bodies of all animals, is made up of systems, that are made up of organs, that are made up of tissues, that are made up of cells.

From Britannica: the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues, organs, and systems. Human anatomy and physiology are treated in many different articles. For detailed coverage of the body's biochemical constituents, see protein; carbohydrate; lipid; nucleic acid; vitamin; and hormone. For information…

Major systems of the human body

Cardiovascular system: blood circulations with heart and blood vessels
Digestive system: processing food with mouth, stomach and intestines
Endocrine system: communicating within the body using hormones
Excretory system: eliminating wastes from the body
Immune system: defending against disease-causing agents
Integumentary system: skin, hair and nails
Muscular system: moving the body
Nervous system: collecting, transferring and processing information with brain and nerves
Reproductive system: the sex organs
Respiratory system: the organs used for breathing, the lungs
Skeletal system: structural support and protection through bones.

Studying human anatomy

Certain professions, especially medicine and physiotherapy, require the study of human anatomy in depth. Textbooks usually split the body into the following regional groups:

Head and Neck - includes everything above the thoracic inlet
Upper limb - includes everything from your hand, forearm, arm, shoulder, axilla, pectoral region and scapular region.
Thorax - contains the region of the chest from the thoracic inlet to the thoracic diaphragm.
Abdomen - everything from the thoracic diaphragm to the pelvic brim or to the pelvic inlet.
The back - about the spine and its components, the intervetebral disks and bodies
Pelvis and Perineum - the pelvis consists of everything from the pelvic inlet to the pelvic diaphragm. The perineum is everything below the pelvic diaphragm.
Lower limb - the lower limb is usually everything below the inguinal ligament, including the thigh, the hip joint, the leg, and the foot.
