Epithelial Tissue -Provides covering (skin) or produce secretions
-No blood supply
-Squamous, cuboidal, and columnar
Connective Tissue -Connects different structures of the body
-Own blood supply, except a few like ligaments
-Bone, cartilage, adipose (fat), and blood vessel
Muscle Tissue -Produces movement
-Skeletal: supports voluntary movement
-Smooth: involuntary control
-Cardiac: involuntary, only in the heart
Nervous Tissue -Provides structure for the brain, spinal cord, and nerves.
Circulatory System (Cardiovascular) -Heart, blood vessels, and blood
-Supports circulation and distribution of various substances
Digestive System -All organs from the mouth to the anus involved in ingestion and breakdown or
processing food.
-Enzymes breakdown food
-Any food not digested is expelled through anus
-Absorption of nutrients is in the small intestine
Endocrine System -Controls body functions
-Glands secrete hormones that travel through blood to organs.
-Pineal, pituitary, thalamus, hypothalamus, thyroid, thymus and adrenal regulate
processes such as growth and metabolism.
Integumentary System Skin, mucous membranes, hair, and nails.
-Protects internal structures from injury, waterproofs the body and helps regulate
body temp.
Lymphatic System -Lymph nodes, lymph vessels (carry lymph), the spleen, the thymus and the tonsils
