11 organ systems
integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, pulmonary (respiratory), digestive, urinary, and reproductive systems
Skin, hair, and nails; covers and protects the body and maintains body temperature
provides speedy communcation signaling within body, sensation (sensory info.), interpretation (consciousness), memory, and movement commands;
brain & spinal cord comprise the Central Nervous System (CNS);
nerves and receptors comprise the Peripheral Nervous System (PNS)
secretes hormones that help control body activities such as growth and reproduction
long-lasting and widespreading chemical signals in blood;
eg, thyroid, adrenal, and pituitary glands
ingests (take in), digests (break down), absorbs (nutrients through cells into blood), excretes waste out of body;
eg, esophagus, stomach, intestines, liver, pancreas
produces offspring and sex hormones & sexual characteristics;
eg, ovaries, uterus, vagina, testes, prostate gland
maintenance of equilibrium within a normal range;
usually through a negative-feedback mechanism
process by which an effector negates/counteracts a stimulus;
returns body to "normal range" (eg body temp);
includes receptor, control center, and effector
neuron(s) that process signal and sends instructions to effector;
found in brain or spinal cord
response of effector increases change of the stimulus—speeds up processes;
no "normal range" of stimulus;
eg, labor contractions and blood clotting

RLQ - contains the appendix;
LUQ - contains the stomach, spleen;

vertical plane through midline of body from head to pelvic floor; cuts body into equal left and right parts
1 of 2 major body cavities; contains cranial cavity (brain) and spinal cavity (spinal cord)
