EX2: Organ Systems & Body Cavities Flashcards
(53 cards)
A group of organs performing a common function
organ system
all organ systems cooperate to maintain an optimal environment for body cells through a process called…
homeostasis
transports nutrients, chemical messengers, gases, and wastes in blood
cardiovascular system
major organs: heart and blood vessels
cardiovascular system
adds oxygen to blood and removes carbon dioxide from blood, produces sound, maintains body fluid pH
respiratory system
major organs: nose, pharynx (throat), larynx, trachea, bronchi, lungs
respiratory system
breaks down food into units that can be absorbed into the body, eliminates waste and non-digestible fiber in food
digestive system
major organs: mouth, salivary glands, pharynx, esophagus, stomach, intestines, pancreas, liver, gallbladder
digestive system
removes nitrogenous wastes, maintains body fluid volume, pH, ad electrolyte levels through urine production
urinary system
major organs: kidneys, urinary bladder, urethra
urinary system
provides a protective barrier for the body and aids in production of vitamin D, eliminates some waste, contains sensory receptors for pain, touch, and temp., fat provides insulination
integumentary system
major organs: skin, hair, nails, sweat glands, oil glands
integumentary system
return fluid to blood, carries dietary lipids from GI tract to blood, detects and eliminates disease causing organisms
lymphatic and immune system
major organs: lymphatic vessels, lymph nodes, spleen, thymus, bone marrow, tonsils
lymphatic and immune system
protects major organs, provides levers and support for body movement, bone marrow contains stem cells that produce blood cells, and is a site for maturation of lymphocytes
skeletal system
major organs: bones and cartilage
skeletal system
moves bones and maintains posture, major source of body heat
muscular system
major organs: skeletal muscles and tendons
muscular system
controls cell function with electrical signals, helps to control body homeostasis
nervous system
major organs: brain, spinal cord, nerves, special sense organs
nervous system
controls cell function with hormones, helps control body homeostasis
endocrine system
major organs: hypothalamus, pituitary gland, pineal gland, thymus, thyroid gland, pancreas, adrenal glands, ovaries, testes
endocrine system
produces gametes and sex hormones, female uterus provides environment for development of fetus
reproductive system
major organs in male: testes, ductus, deferens, penis
major organs in female: ovaries, uterine tubes, uterus, vagina
reproductive system
