anatomy - focuses on the structure of the body and how it is designed
physiology - how the body functions
body at the chemical level - look at atoms
atoms comine to form - molecules
molecules combine to form - macromolecules (proteins and nucleic acids)
macromolecules combine to form - organelles (working structures: nucleus)
organelles combine to form - cells
cells combine to form - tissues
tissues combine to form - organs
organs combine to form - system of organs
system of organs combine to form - organism
cells are - smallest unit of living organisms and comprise the cellular level
tissues are groups of cells that - preform a common function
four basic tissue types - epithelium, connective, muscle, nervous
epithelial tissue - covers the body surface and lines the cavities of the body
cells that make up epithelial tissue are - specialized for tasks such as secretion and
absorption
structure of epithelial tissue - contains closely packed cells with very little matrix (layer
outside the cells)
epithelial tissue can be found as - one layer or in many layers
connective tissue offers - support and protection of body organs (bones, tendons, blood,
and ligaments)
connective tissue cells are specialized - to bind tissues together and play a supportive
role
, nervous tissue is responsible for - communication between the cells of the body by
forming a system of electrical impulses that communicate very rapidly
nerves are like - the "wiring" of the body
together tissues make up - the organ structure level of the body
integumentary system - layers that make up our skin
skin is made up of - epidermis (outer)
dermis (middle)
hypodermis "subcutaneous' (inner)
hypodermis is made up of - mostly fat that helps anchor the dermis to a layer of fat cells
adipocytes - fat cells that help to insulate and regulate body temp
integumentary system produces - vitamin D and contains pain receptors and pressure
receptors used in our protection
if the integumentary system is damaged and microbes or chemicals make way into our
body it is the - lymphatic system that is responsible for mounting the attack to defend
our internal environment
skeletal system - serves as the framework for the muscular system and supports the
body organs
skeletal system provides - protection for internal organs and houses blood cells as well
as stores minerals
muscular systems allows for - movement of the body
muscles attach to bones - to bring movement to the skeletal system
nervous system provides - internal communication among the cells of the body
our nervous system uses - electrical impulses to communicate within the body and
enable the body to respond the the internal and external environments
digestive system - breaks down food into small molecules
small molecules enter - the bloodstream through the small intestine and supply the body
with nutrients
