sagittal plane | divides the body into left and right potions |
transvere (horizontal plane) | divides the body into upper and lower portions |
coronal plane | divides the body into anterior and posterior portions |
anatomy | study of the structure of body parts and how they relate to each other |
physiology | study of the function of body parts |
thoracic cavity | enclosed by the rib cage and contains the lungs, heart, trachea and esophagus |
mediastinum | middle portion of the thoracic cavity contains the heart, thymus gland, trachea and esophagus |
plueral cavity | contains the lungs |
pericardial cavity | contains the heart |
diaphragm | muscle that separates the thoracic and abdominopelvic cavities |
abdominal cavity | inferior to the diaphragm contains the stomach, liver, large and small intestines, etc. |
pelvic cavity | inferior to the abdominal cavity contains reproductive organs, urinary bladder, and lower colon |
lymphatic system | picks up fluid leaked from tissues involved with immunity |
endocrine system | secretes chemicals that act a messengers between body parts |
circulatory system | transports nutrients to cells and carries wastes away |
muscular system | important in locomotion and generating body heat |
digestive system | breaks down food; absorbs nutrients; removes solid waste from the body |
skeletal system | support and protection of the body;site of blood cell production, stores minerals |
integumentary system | external support and protection;synthesizes vitamin D |
urinary system | eliminates nitrogenous waste from the body |
nervous system | integrates and coordinate all other body systems |
circulatory system | heart blood vessels |

muscular system | skeletal muscle, tendons |
skeletal system | bones, ligaments and joints |
integumentary system | skin, hair, nails, sweat glands, oil glands |
homeostasis | the relative constancy of the body's internal environment |
negative feedback mechanism | feedback mechanism that returns the body to its original state (towards homeostasis) ex. regulation of blood glucose levels, body temp, rate of breath, etc. |
positive feedback mechanism | feddback mechanism that moves the internal environment of the body away from homeostasis ex. childbirth, blood clotting |
