Human Anatomy Organ Systems Quiz

• The human anatomy quiz is broken down into 11 major organ systems with 10 multiple choice questions each.
• In the skeletal system section, questions included types of bones, joints, bone counts, bone cells, and bone names.
• Examples of questions in the skeletal system section were about the axial skeleton, bone cells, collarbone, joint types, and functions of bones.
• Moving on to the muscular system section, questions covered types of muscles, energy sources for muscle contractions, connective tissues, muscle functions, and muscle fiber types.
• The muscular system questions addressed voluntary muscles, energy sources for muscle contractions, connective tissues attaching muscles to bones, muscle functions, and muscle fiber types suited for endurance activities.- Muscle contraction types: eccentric contraction involves muscle lengthening during tension.
• Muscle groups responsible for bending the elbow and flexing the knee: biceps for elbow, hamstrings for knee.
• Primary function of smooth muscle tissue: involuntary movement.
• Skin layers: epidermis produces new skin cells.
• Sweat glands: apocrine glands produce sweat with odor.
• Hair color: melanin gives hair its color.
• Skin layer with blood vessels, nerve endings, and hair follicles: dermis contains them.
• Oil produced in sebaceous glands: sebum.
• Common skin condition from inflammation of sebaceous glands: acne.
• Integumentary system's primary function: protect the body from injury and infection.
• Dead skin layer on palms and soles: stratum lucidum.
• Fine hair covering the body: vellus hair.
• Gland responsible for producing earwax: ceruminous glands.
• Nervous system functions: sensory input, homeostasis (not movement of the body).
• Brain parts: brain stem regulates vital functions, dendrite receives information from neurons, occipital lobe processes visual information, frontal lobe regulates emotions, cerebellum coordinates movement, pituitary gland produces human growth hormone.
• Endocrine system: pancreas produces insulin, cortisol is a steroid hormone, parathyroid hormone regulates calcium, adrenal glands located on top of kidneys, oxytocin stimulates uterine contractions.
• Cardiovascular system: transports oxygen and nutrients to cells, arteries carry blood away from the heart, left atrium receives oxygenated blood, mitral valve located between left atrium and ventricle, left ventricle pumps oxygenated blood to body, aorta is the largest artery, atherosclerosis is the buildup of fatty deposits in arteries, bradycardia is a slow heart rate, red blood cells carry oxygen.
• Lymphatic system: maintains fluid balance and immune function, lymph circulates through the system, lymphocytes are white blood cells, lymph nodes filter lymph, spleen is the largest lymphatic organ.
• Respiratory system: diaphragm separates chest and abdominal cavities, alveoli are tiny air sacs for gas exchange, emphysema is the destruction of alveoli walls, trachea is the windpipe, epiglottis prevents food from entering trachea.
• Digestive system: ingestion is the first step, liver produces bile, pancreas secretes digestive enzymes, small intestine is primary site for nutrient absorption, cck stimulates bile release, water is primarily absorbed in the large intestine.
• Urinary system: kidneys clean blood and produce urine, urea is a waste product, ureter carries urine to bladder, urination is the process of expelling urine, kidneys secrete erythropoietin to stimulate red blood cell production.
• Reproductive system: ovulation is the release of an egg from the ovary, females have XX sex chromosomes, fertilization usually occurs in the fallopian tubes, prostate gland secretes seminal fluid, zygote is a fertilized egg, testosterone develops male secondary sexual characteristics.

Test your knowledge on the 11 major organ systems in the human body with this quiz, including skeletal, muscular, integumentary, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems.
