Tissue Role in Body Where Found
Epithelial Covers external body structures lines internal body structures Skin, blood vessels, lining organs
Connective Connects and protects parts of the body Bone, tendons, cartilage, blood
Muscle Contracts to produce movement Biceps and other muscles, tongue, heart
Nervous Transmits and processes information Brain, Spinal cord, nerves
3
System Role in Body Major Organs
Respiratory Exchanges O2and CO2 between the body and the external environment Nose, pharynx, larynx, trachea, bronchi, lungs, Alveoli
Circulatory Transports oxygen, nutrients, and other needed materials to cells transports waste away from cells Heart, blood vessels, blood
4
System Role in Body Major Organs
Nervous Detects and responds to changes in the environment transmits information throughout the body Brain, spinal cord (central), nerves, sensory organs (Peripheral)
Digestive Breaks down food into nutrients cells can use disposes of solid wastes Mouth(tongue, teeth, salivary glands), pharynx, esophagus, stomach, small intestine, large intestine, liver, pancreas, gall bladder
5
System Role in Body Major Organs
Excretory Removes waste, including excess water, unusable materials from food, CO2 , and harmful materials Skin lungs Urinary kidneys, bladder, ureters, urethra Rectum anus
Muscular Moves the body moves material through the body Skeletal muscles, tendons, smooth muscle, cardiac muscle
Skeletal Moves and supports the body protects internal organs, blood cell formation, storage Bones, cartilage, ligaments

System Role in Body Major Organs
Reproductive Produces sex cells produces offspring Males- testes, prostate gland, penis, vas deferens Females- ovaries, fallopian tubes, vagina, uterus, breasts
Immune Protects against disease Lymph nodes, lymph vessels, white blood cells

System Role in Body Major Organs
Integumentary Separates the body and the external environment, Skin, hair, nails
Endocrine Secrets hormones to regulate body functions. Coordinates organ systems. Helps maintain balance in body systems. Endocrine glands pituitary, pineal, hypothalamus, thymus, thyroid, parathyriod, adrenals, pancreas, testes, ovaries
