Body Structures

Maintaining boundaries

Separating the inside of the body from the outside environment

Movement

Movement of the body, organs, and substances within the body

Responsiveness

Ability to sense and respond to changes in the environment

Digestion

Breaking down food into usable nutrients

Metabolism

All chemical reactions that occur in the body

Reproduction

Producing new cells or a new organism

Growth

Increasing the size or number of cells

Integumentary system

Protects the body, helps regulate temperature, provides sensation, and prevents water loss

Integumentary system organs

Skin, hair, nails, sweat glands, and oil glands

Skeletal system

Provides support, protects organs, allows movement, produces blood cells, and stores minerals

Skeletal system organs

Bones, cartilage, ligaments, and bone marrow

Muscular system

Produces movement, maintains posture, and produces body heat

Muscular system structures

Skeletal muscle, smooth muscle, and cardiac muscle

Nervous system

Controls and coordinates the body and allows it to respond to stimuli

Nervous system organs

Brain, spinal cord, nerves, and sensory organs

Endocrine system

Produces hormones and regulates growth, metabolism, reproduction, and homeostasis

Endocrine system organs

Pituitary gland, thyroid gland, adrenal glands, pancreas, ovaries, and testes

Cardiovascular system

Transports oxygen, nutrients, hormones, and wastes throughout the body

Cardiovascular system organs

Heart, blood, arteries, veins, and capillaries

Lymphatic/immune system

Fights infections, removes excess fluid, absorbs fats, and protects against pathogens

Lymphatic/immune system organs

Lymph, lymph vessels, lymph nodes, spleen, thymus, and tonsils

Respiratory system

Brings oxygen into the body and removes carbon dioxide

Respiratory system organs

Nose, pharynx, larynx, trachea, bronchi, lungs, and diaphragm

Digestive system

Breaks down food, absorbs nutrients, and removes solid waste

Digestive system organs

Mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, pancreas, rectum, and anus

Urinary system

Removes waste from the blood and regulates water, salts, and blood pressure

Urinary system organs

Kidneys, ureters, urinary bladder, and urethra

Female reproductive system

Produces eggs and hormones and supports fertilization and pregnancy

Female reproductive system organs

Ovaries, fallopian tubes, uterus, and vagina

Male reproductive system

Produces sperm and hormones and delivers sperm for reproduction

Male reproductive system organs

Testes, epididymis, vas deferens, seminal vesicles, prostate gland, penis, and urethra

Respiratory + cardiovascular system

Respiratory system brings oxygen into the lungs and the cardiovascular system transports it through the blood

Digestive + cardiovascular system

Digestive system provides nutrients and the cardiovascular system transports them around the body

Urinary + cardiovascular system

Kidneys filter wastes from the blood

Nervous + muscular system

Nervous system controls muscle movement

Skeletal + muscular system

Bones and muscles work together to produce movement

Nervous + endocrine system

Both systems control and coordinate body functions

Endocrine + reproductive system

Hormones regulate reproduction and development

Lymphatic/immune + cardiovascular system

Lymphatic system returns excess fluid to the bloodstream and helps protect the body

Integumentary + nervous system

Skin contains sensory receptors that detect changes in the environment

Digestive + lymphatic system

Lymphatic system helps absorb fats from the digestive tract
