study of body structure
study of the body and its functions
A group of cells that work together for a common function
A group of tissues that work together for a common function
group of organs that work together to perform a specific function
covers and protects the body from infection, heat and moisture loss
provides support and protection for the body and its organs
Ingest food and breaks it down into smaller unites to be used by the body
The human body system that contains the heart, blood, and all of the blood vessels. It delivers all the nutrients to the cells and removes wastes
system responsible for taking in oxygen and releasing carbon dioxide using the lungs
Coordinates body's activities by detecting stimuli and directing the body's responses
Enables body movement
the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream.
the system that removes waste from your body and controls water balance
a secondary circulatory system that helps the body fight pathogens and maintain its fluid balance
Defends the body against infections
system of organs involved in producing offspring
a body tissue that covers the surfaces of the body, inside and out
Groups of cells that support the body and hold it together
tissue that receives messages from the body's external and internal environment, analyzes the data, and directs the response
a cell that is specialized to conduct nerve impulses
Voluntary, striated muscle that moves bones, works in pairs and is attached to bones by tendons
Striated, involuntary muscle found only in the heart
involuntary, non-striated muscle found mainly in organs
process by which organisms maintain a relatively stable internal environment
a chemical that serves as a messenger. Each hormone is secreted by a gland and travels to one or more target organs, where it brings about responses.
fluid in the spaces between cells
the outer layer of the skin covering the exterior body surface of vertebrates
a pigment that gives the skin its color
the deep vascular inner layer of the skin
Subcutaneous tissue layer below the dermis
hard protein material found in the epidermis, hair, and nails
individual segment of the backbone; encloses and protects the spinal cord
a connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together
produces blood cells
bone marrow that is yellow with fat
strong connective tissue that holds bones together in movable joints
strong connective tissue that attaches muscle to bone
an elongated contractile cell that forms the muscles of the body
one of many contractile filaments that make up a striated muscle fiber
contractile unit of muscle
protein that mainly makes up the thin filaments in striations in skeletal muscle cells
protein that makes up the thick filaments in striations in skeletal muscle cells
