Organ systems

Integumentary system

skin, hair, nails, sweat and oil glands

regulates body temperature, eliminates some wastes, detects sensations, protects

Skeletal system

bones, joints, cartilage

supports and protects body, assists in movement, produces blood cells, stores minerals and lipids

Muscular system

skeletal, cardiac and smooth muscle tissue

powers movements of the body, stabilizes body position, generates heat

Cardiovascular/circulatory system

blood, heart, blood vessels

pumped blood carries oxygen/nutrients to cells and carbon dioxide/wastes away from cells

helps regulate pH, temperature and water content of body fluids

helps defend against disease and mend damaged blood vessels

lymphatic/immune system

lymph, lymphatic vessels, spleen, thymus, tonsils

returns proteins and plasma to the cardiovascular system

site of maturation/proliferation of WBCs

production of antibodies to combat disease 

transport of fats from GI tract to cardiovascular system

nervous system

brain, spinal cord, nerves and sense organs

regulates body activities in response to internal and external stimuli

interprets stimuli and responds through muscular contraction or glandular secretions

Endocrine system

pituitary, thyroid and pancreas

regulates body activities through hormones, chemicals transported in the blood to target cells

Respiratory system

lungs and airways leading in and out

transfers oxygen from inhaled air to blood and carbon dioxide from blood to exhaled air

helps regulate pH balance of body fluids 

Digestive system

mouth, esophagus, stomach, intestines (GI tract organs) salivary glands, pancreas, liver, gallbladder (accessory organs)

physical and chemical breakdown of foods absorbs nutrients, eliminates solid wastes

Urinary system

kidneys, ureter, urinary bladder, urethra

regulated volume and chemical composition of blood

eliminates metabolic wastes 

regulates fluid and electrolyte balance

helps maintain pH of body fluids and calcium balance of the body secretes hormone that regulate RBC production 

reproductive system

gonads (testes/ovaries) uterus, vagina, ductus, deferens, epididymis, penis 

produce gametes and releases hormones that regulate reproduction

transport and store gametes
