4 types of tissue

Function of epithelial tissue

• Protection, Secretion, Absorption, Excretion, Sensory Perception, Filtration, Diffusion, and Osmosis

• Strength, Support,  Elasticity, Stores fat, Protects against infection,  Produces RBC,  Helps repair tissue

• Communication system of the body. Tells the brain and spinal cord about the outside world and reacts to this information with a response.

• Movement, support, protection, heat generator, blood circulator, control heartbeat, breathing, digestion

Function of connective tissue

• Strength, Support,  Elasticity, Stores fat, Protects against infection,  Produces RBC,  Helps repair tissue

• Communication system of the body. Tells the brain and spinal cord about the outside world and reacts to this information with a response.

• Movement, support, protection, heat generator, blood circulator, control heartbeat, breathing, digestion
