Human Body Parts & their functions

Regional groups

• Head and neck – includes everything above the thoracic inlet.
• Upper limb – includes the hand, wrist, forearm, elbow, arm, and shoulder.
• Thorax – the region of the chest from the thoracic inlet to the thoracic diaphragm.
• Human abdomen to the pelvic brim or to the pelvic inlet.
• The back – the spine and its components, the vertebrae, sacrum, coccyx, and intervertebral disks.
• Pelvis and Perineum – the pelvis consists of everything from the pelvic inlet to the pelvic diaphragm. The perineum is the region between the sex organs and the anus.
• Lower limb – everything below the inguinal ligament, including the hip, the thigh, the knee, the leg, the ankle, and the foot.

[edit]Major organ systems

• Circulatory system: pumping and channeling blood to and from the body and lungs with heart, blood, and blood vessels.
• Digestive System: digestion and processing food with salivary glands, esophagus, stomach, liver, gallbladder, pancreas, intestines,rectum, and anus.
• Endocannabinoid system: neuromodulatory lipids and receptors involved in a variety of physiological processes including appetite, pain-sensation, mood, motor learning, synaptic plasticity, and memory.
• Endocrine system: communication within the body using hormones made by endocrine glands such as the hypothalamus, pituitary or pituitary gland, pineal body or pineal gland, thyroid, parathyroids, and adrenals or adrenal glands
• Integumentary system: skin, hair and nails
• Immune system: the system that fights off disease; composed of leukocytes, tonsils, adenoids, thymus, and spleen.
• Lymphatic system: structures involved in the transfer of lymph between tissues and the blood stream, the lymph and the nodes andvessels that transport it.
• Musculoskeletal system: muscles provide movement and a skeleton provides structural support and protection with bones, cartilage,ligaments, and tendons.
• Nervous system: collecting, transferring and processing information with brain, spinal cord, peripheral nerves, and nerves
• Reproductive system: the sex organs; in the female; ovaries, fallopian tubes, uterus, vagina, mammary glands, and in the male; testes,vas deferens, seminal vesicles, prostate, and penis.
• Respiratory system: the organs used for breathing, the pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
• Urinary system: kidneys, ureters, bladder and urethra involved in fluid balance, electrolyte balance and excretion of urine.
• Vestibular system: contributes to our balance and our sense of spatial orientation.
