structural hierarchy Flashcards
tissues
similar cells that perform particular function
- epithelial
- connective
- muscle
- nervous
epithlelial
- covers organ surfaces
- involved with protection, absorption, and excretion
connective tissues
- binds, supports, and protects body parts
- stores energy and minerals
muscle tissues
contracts to produce movement
nervous tissue
transmits nerve impulses that coordinate body activities
organs
structures of different tissues specialized to carry out specific functions
ex: stomach
organ systems
group of organs and structures that work together to perform vital body function
digestive system
ingests food, breaks down into small units
nervous system
- sense environment, affect responses, coordinate body activities
- brain, spinal cord, nerves, and sense organs work together
muscular system
skeletal muscles provide movement as they work with skeletal system
skeletal system and integumentary system
- bones and cartilage provides support and protection
- skin, hair, nails protect internal body parts from injury and infection
lymphatic and immune system
system of cells and process that protects body from foreign invaders
excretory system
- kidney, bladder, urethra remove nitrogen containing wastes from blood
endocrine system
endocrine glands secrete hormones into blood that regulate other activities
reproductive system
