Organ Systems Flashcards
(14 cards)
Levels of Human Structure
Name all Organ Systems
Integumentary, Skeletal, Muscular, Nervous, Endocrine, Circulatory, Lymphatic, Respiratory, Digestive, Urinary, Male and Female Reproductive
Nervous System
Main organs = Brain, spinal cord, nerves, ganglia
Main function:
Rapid internal communication, coordination, motor control and sensation
Endocrine System
Releasing hormones that result in long term changes in the activities of organ systems
Main organs = pituitary gland, pineal gland, thyroid gland, parathyroid gland, thymus, adrenal glands, pancreas, testes, ovaries
Main functions:
Hormone production, internal chemical communication and coordination
Respiratory System
Delivery of oxygen to where gas exchange can occur between the air and circulating blood
Main organs = Nose, lungs, pharynx, larynx, trachea, bronchi
Main functions = absorption of oxygen, release of CO2
Digestive System
Processing of food and absorption of organic nutrients, minerals, vitamins, and water
Main Organs = teeth, tongue, esophagus, stomach, small and large intestines, liver, gallbladder, pancreas
Main functions = nutrient breakdown and absorption
Liver controls metabolism of carbs, fats, proteins, vitamins, and minerals
Urinary System
Main organs = Kidneys, ureters, urinary bladder, urethra
Main functions = Elimination of excess water, salts, and waste products, controls pH of body fluids
Integumentary System
Main organs = Skin, hair, nails, glands
Main functions: protection, water retention, thermoregulation, sensation
Skeletal System
Main Organs = Bones, Cartilages, ligaments
Main functions: support, movement, blood formation
Muscular System
Main organs = all muscle
Main Functions = Movement, stability, communication, heat production
Lymphatic System
Main organs = Lymph nodes, Lymphatic vessels, thymus, spleen, tonsils
Main functions = defense against illness, production of immune cells, detection of pathogens
Circulatory System
Main Organs = Heart, blood vessels
Main functions = distribution of nutrients, oxygen, electrolytes, heat, immune cells, and antibodies
Female Reproductive System
Main Organs = Ovaries, uterine tubes, uterus, vagina, mammary glands
Main functions = production of eggs, fertilization and fetal nourishment, birth, lactation,
Male Reproductive System
Main Organs: Testes, penis, prostate gland, etc
Main Functions: Production and Delivery of Sperm, secretion of sex hormones
