chemical level of organization - atoms and molecules
cellular level of organization - molecules combine to form cells
tissue level of organization - groups of cells and the materials surrounding them that work together to
perform a particular function

11 systems of the human body - 1. Integumentary
2. Skeletal
3. Muscular
4. Nervous
5. Endocrine
6. Cardiovascular
7. Lymphatic
8. Respiratory
9. Digestive
10. Urinary
11. Reproductive
functions of integumentary system - protection, body temperature regulation, cutaneous sensation,
metabolic functions, blood reservoir, excretion
components of integumentary system - skin, hair, nails, sweat glands, oil glands, mammary glands
, Functions of the skeletal system - support, storage of minerals and lipids, blood cell production,
protection, leverage
components of skeletal system - All Bones, Joints, Cartilage, Ligaments
Functions of the muscular system - movement, posture, joint stability, heat production
components of muscular system - skeletal muscles
Functions of the nervous system - Generates action potentials (nerve impulses) to regulate body
activities; detects changes in body's internal and external environments, interprets changes, and
responds by causing muscular contractions or glandular secretions
Components of the Nervous System - brain, spinal cord, nerves
functions of the endocrine system - Regulates body activities by releasing hormones
components of endocrine system - Hormone-producing glands (pineal gland, hypothalamus, pituitary
gland, thymus, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries, and testes) and
hormone-producing cells in several other organs
Functions of the cardiovascular system - Heart pumps blood through blood vessels; blood carries oxygen
and nutrients to cells and carbon dioxide and wastes away from cells and helps regulate acid-base
balance, temperature, and water content of body fluids; blood components help defend against disease
and repair damaged blood vessels
Components of the cardiovascular system - heart, blood vessels, blood
components of lymphatic system - lymphatic fluid and vessels, spleen, thymus, lymph nodes, and tonsils
Functions of the lymphatic system - Returns proteins and fluid to blood; carries lipids from
gastrointestinal tract to blood
Functions of the respiratory system - Transfers oxygen from inhaled air to blood and carbon dioxide from
blood to exhaled air; helps regulate acid-base balance of body fluids; air flowing out of lungs through
vocal cords produces sounds
Components of the respiratory system - lungs, pharynx, larynx, trachea, bronchial tubes
function of digestive system - break down and absorbs nutrients from food; removes waste; maintains
water balance
components of digestive system - mouth, pharynx, esophagus, stomach, intestines, liver, pancreas, anus
function of urinary system - stores, and eliminates urine; eliminates wastes and regulates volume and
chemical composition of blood;
Components of the Urinary System - kidneys, ureters, bladder, urethra
functions of the reproductive system - production of gametes, fertilization, development and
nourishment of new individual, production of reproductive hormones
components of reproductive system - Gonads (testes, ovaries) and associated organs
