a type of connective tissue consisting of living cells held in a rigid matrix of collagen fibers embedded in calcium salts
a flexible connective tissue consisting of living cells and collagenous fibers embedded in a rubbery matrix
the organ system that transports materials such as nutrients and other wastes from body cells
animal tissue that functions mainly to bind and support other tissues, having a sparse population of cells scattered through an extracellular matrix, which they produce
the organ system involved in ingestion and digestion of food, absorption of nutrients, and elimination of wastes
the organ system consisting of ductless glands that secrete hormones and the molecular receptors on or in target cells that respond to the hormones

the organ system consisting of the skin and its derivatives, such as hair and nails in mammals

Loose Connective Tissue
the most widespread connective tissue in the vertebrate body it binds epithelia to underlying tissues and functions as packing material, holding organs in place
the vertebrate organ system through which lymph circulates; includes lymph vessels, lymph nodes and the spleen
tissue consisting of long muscle cells that can contract, either on its own or when stimulated by nerve impulses; the most abundant tisue in a typical animal
a primary mechanism of homeostasis, whereby a change in a physiological variable triggers a response that counteracts the initial change.
the organ system that forms a communication and coordination network between all parts of an animal's body
a nerve cell; the fundamental structural and functional unit of the nervous system, specialized for carrying signals from one location in the body to another
functions in exchanging gases with the environment. supplies the blood with O2 and disposes CO2
type of striated muscle attached to the skeleton; generally responsible for voluntary movements of the body
