Organ Systems Flashcards
Lymphatic system
Principal organs: lymph nodes, lymphatic vessels, thymus, spleen, tonsils
Principal functions: recovers excess tissue fluid, detects pathogens, produces immune cells, defends against disease
Respiratory system
Principal organs: nose, pharynx, larynx, trachea, bronchi, lungs
Principal functions: absorbs oxygen, discharges carbon dioxide, balances pH, allows speech (vocals)
Urinary System
Principal organs: kidneys, ureters, urinary bladder, urethra
Principal functions: eliminates waste, regulates blood volume and pressure, stimulates red blood cell formation, controls fluids/electrolytes/pH, detoxifies the body
Nervous System
Principal organs: brain, spinal cord, nerves, ganglia
Principal functions: rapid internal communication, coordination, motor control, and sensation
Endocrine System
Principal organs: pituitary gland, pineal gland, thyroid gland, parathyroid gland, thymus, adrenal gland, pancreas, testes, ovaries
Principal functions: produces hormones, internal chemical communication and coordination
Integumentary system
Principal organs: hair, skin, nails, cutaneous glands
Principal functions: protection, water retention, vitamin D production, cutaneous sensation, thermoregulation, nonverbal communication
Skeletal System
Principal organs: bones, cartilages, ligaments
Principal functions: support, movement, protection of enclosure of viscera, blood formation, mineral storage, electrolyte/pH balance
Muscular System
Principal organs: skeletal muscles
Principal functions: movement, stability, communication, control of body openings, heat production
Digestive System
Principal organs: teeth, tongue, salivary glands, esophagus, stomach, small and large intestines, liver, pancreas, gallbladder
Male Reproductive System
Principal organs: testes, epididymides, spermatic ducts, seminal vesicles, prostate, bulbourethral glands, penis
Principal functions: production/ delivery of sperm, secrete sex hormones
Female Reproductive System
Principal organs: uterus, uterine tubes, ovaries, vagina, mammary glands
Principal functions: production of eggs, site of fertilization and fetal development, give birth, lactate, secrete sex hormones
