any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.
The 4 types of tissues are:
muscular, epithelial, nervous, and connective.
Muscular- The functions of this tissues are aiding the body in movement, flexibility, pumping of blood, digestion, brain activity, and breathing movement.
Epithelial- transportation of materials and protection of underlying tissues
Nervous- transmit nerve impulses
Connective- provides structural support for the tissues and organs of the body
Muscular- skeletal or cardiac muscle
Epithelial- cell shape and arrangement
Nervous- neurons ad neuroglia
Connective- holds body together
Specializations of epithelia:
the movement of fluids over the epithelial surface, providing protection and lubrication
the movement of fluids through the epithelium, to control permeability
the production of secretions that provide physical protection or act as chemical messengers
Examples of where these 4 types can be found:
Muscles- towards the bones because their job is to move the bones
Epithelial- Respiratory system and the skin
Nervous- brain and spinal cord
Connective- bone and cartilage
