Term
Interstitial Fluid
Definition
Liquid found in many animals, fills spaces between cells, as a link for "exchange surfaces". ex: interaction with circulatory fluid enables cells throughout the body to obtain nutrients and rid wastes.
Term
The Four Animal Tissues
Definition
Epithelial, connective, muscle and nervous
Term
Epithelial Tissue
Definition
Occuring in sheets of cells that cover the outside of the body and line organs and cavities within the body. Closely packed to prevent again mechanical injury, pathogens and fluid loss. Different Arrangements include Stratified squamous, Simple squamous and columnar, cuboidal and Pseudostratified.
Term
Connective Tissue
Definition
Sparse population of cells that are scattered though an extracellular matrix (web of fibers embedded in a liquid, jellylike or solid foundation)-- holds many tissues and organs together and in place---HENCE THE NAME CONNECTIVE ;)
Term
Muscle Tissue
Definition
Necessary for movement. Cells contain filaments which themselves contain the proteins actin and myocin. 3 types of mt are Skeletal, Smooth and Cardiac.
Term
Actin and Myosin
Definition
Proteins in muscles cells that allow contraction
Term
Smooth Muscle
Definition
Lacking striations, found in the walls of digestive tract, bladder, arteries etc. Responsbile for involuntary movements.
Term
What two systems are responsible for coordination and control of body systems?
Definition
The nervous and the endocrine system
Term
Endocrine system (coordination and control details)
Definition
signaling molecules released into the bloodstream by endocrine cells are carried to all locations in the body.
Term
Nervous system (coordination and control details)
Definition
neurons transmit signals along dedicated routes connecting SPECIFIC locations in the body.
