Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive
From smallest to largest, what is the makeup of the body?
CHEMICAL LEVEL: atoms combine to form molecules
-Atoms
-Molecules
-Organelles
CELLULAR LEVEL: cells are made up of molecules
-Smooth muscle cell
TISSUE LEVEL: tissues consist of similar types of cells
-Smooth muscle tissue
ORGAN LEVEL: organs are made up of different types of tissues
-Blood Vessel (organ made up of epithelial, smooth muscle, and connective tissue)
ORGAN SYSTEM LEVEL: organ systems consist of different organs that work together closely
-Cardiovascular system
ORGANISMAL LEVEL: human organisms are made up of many organ systems
What is anatomical position?
Standing erect, feet facing forward, arms to the side, palms forward
What is Superior (Cranial)
Towards the head; above

What is medial?
Towards the midline of the body; the inner side of
(ex. belly button)
What is lateral?
Away from the midline of the body; the outside of
(ex. shoulders)
What is intermediate?
Between a more medial and a more lateral structure
(ex. collarbone)
What is proximal?
Close to the attachment point of a limb to the body
(ex. arm)
What is distal?
Away from the attachment point of a limb to the body
(ex. wrist/fingers)
What is superficial?
Towards the body’s surface
