homeostasis
Maintenance of a stable internal environment
Thoracic Membranes
Pleura
Heart membranes
Pericardium
Abdominopelvic Membranes
Peritoneum
integumentary system
includes skin, hair, nails, and various glands, covers the body, senses changes outside the body, and helps regulate body temperature
skeletal system
made up of bones and ligaments. It supports, protects, provides frameworks, stores inorganic salts, and houses blood-forming tissues
muscular system
Consists of the muscles that provide body movement, posture, and body heat
nervous system
consists of the brain, spinal cord, nerves, and sense organs. It integrates incoming information from receptors and sends impulses to muscles and glands
endocrine system
including all of the glands that secrete hormones, helps to integrate metabolic functions
