The body as a whole is a unit constructed of the following smaller units | Chemical level - atoms and molecules
Cells
Tissues
Organs—organizations of different kinds of tissues
Systems—organizations of many different kinds of organs
Organisms-made up of organ systems |
Cells- | the smallest structural units; organizations of various chemicals |
Tissues— | organizations of similar cells |
Organs— | organizations of different kinds of tissues |
Systems— | organizations of many different kinds of organs |
Organisms- | made up of organ systems |
Structural Units: Cells | -Smallest units of life
-Perform all activities necessary to maintain life
EX: Metabolism, assimilation, digestion, excretion, reproduction |
Structural Units: Tissues | -Made up of different types of cells
Epithelial: covers and protects
Connective: binds and supports other tissues
Muscle: movement
Nervous: connects sensory structures to motor structures |
The integumentary System function | external covering or the skin that covers our body providing waterproofing, sensory cushioning and protection of our deeper tissue from injury as well as vitamin D synthesize. It also excretes salts, urea in our sweat and regulates body temperature. |

. Skeletal System function | consist of bones, cartilages, ligaments and joints that support the body and framework used by muscles for movement. It also protects us from harm as well as provides formation of blood cells within the bone and stores minerals |
. Muscular System is | contractions/ shorten of the muscles causing movement, mobility. This functions as movement, standing, smiling, but also the beat of the heart, fluid movements and other substance through the body. |
