Structure and Function
what is structure?
Structure refers to something’s form, makeup or arrangement.
What is the first level of organization
Atoms
What is homeostasis
the ability to maintain a relatively constant internal environment in the body despite changes “outside”
What are the 11 body systems
integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems
Anatomical position, or standard anatomical position, refers to the positioning of the body when it is standing upright and facing forward with each arm hanging on either side of the body, and the palms facing forward. The legs are parallel, with feet flat on the floor and facing forward.
It is the scientifically agreed upon reference position for anatomical location terms

Physiology is the study of the function of body structures.
How are complex and simple parts related
Complex parts such as organ systems are made up of tissues which are made up of cells. Simple parts help create the complex.
