Body Systems

Function of the integumentary system

forms the external body covering
protects deeper tissues from injury synthesizes vitamin d
houses cutaneous (pain, pressure) receptors, sweat, and oil glands

What structures are in the integumentary system?

skin, hair, nails

Function of the skeletal system

protects and supports body organs and provides a framework the muscles use to cause movement
blood cells are formed within bones
bones store minerals

What structures are in the skeletal system?

joints, bones

Function of the muscular system

allows manipulation of environment, locomotion, and facial expression
maintains posture, and produces heat

What structures are in the muscular system?

skeletal muscles

Function of the nervous system

as the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands

What structures are in the nervous system?

brain, spinal cord, nerves

Function of the endocrine system

glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells

What structures are in the endocrine system?

pineal gland, pituitary, thyroid gland, thymus, adrenal gland, pancreas, testis, overy

Function of the cardiovascular system

blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc
the heart pumps blood

What structures are in the cardiovascular system

heart, blood, vessels

Function of the lymphatic system/immunity

picks up fluid leaked from blood vessels and returns it to blood
disposes of debris in the lymphatic stream
houses white blood cells involved in immunity
the immune response mounts the attack against foreign substances within the body

What structures are in the lymphatic system/immunity

red bone marrow, thymus, lymphatic vessels, thoracic duct, spleen, lymph nodes

Function of the respiratory system

keeps blood constantly supplied with oxygen and removes carbon dioxide
the gaseous exchanges occur through the walls of the air sacs of the lungs

What structures are in the respiratory system

nasal cavity, pharynx, larynx, trachea, bronchus, lungs

Function of the digestive system

breaks down food into absorbable units that enter the blood for distribution to body cells
indigestible foodstuffs are eliminated as feces

What structures are in the digestive system

oral cavity, esophagus, liver, stomach, small intestine, large intestine, rectum, anus

Function of the urinary system

eliminates nitrogenous wastes from the body
regulates water, electrolytes, and acid-base balance of the blood

What structures are in the urinary system

kidney, ureter, urinary bladder, urethra

Function male and female reproductive system

Production of offspring
Testes produce sperm and male sex hormone and males ducts and glands aid in the delivery or sperm to the female reproductive tract
Ovaries produce eggs and female sex hormones
The remaining female structures serve as sites for fertilization and development of the fetus
Mammary glands of female breasts produce milk to nourish the newborn

What structures are in the male reproductive system?

prostate, penis, testis, scrotum, ductus deferens

What structures are in the female reproductive system?

mammary glands, ovary, uterus, vagina, uterine tube
