Nursing ATI TEAS 7 Test EXAM 2024-2025 QUESTIONS AND ANSWERS100 % PASS A+ GRADE
What is the integumentary system's responsibility? - answer>>some excretion (water, sodium, chloride,
magnesium, lactic acid) via glands
Endocrine System (main functions) - answer>>regulates many functions in the body by secreting
hormones (chemicals that act as signals) into the circulatory system. Hormones include insulin,
glucagon, melatonin, epinephrine, norepinephrine, oxytocin, growth hormone, luteinizing hormone,
antidiuretic hormone, thyroxine, cortisol.
Major glands in the endocrine system - answer>>pineal and pituitary (brain), thyroid and parathyroid
(neck), thymus (behind sternum), adrenals (on top of kidneys), pancreas, and ovaries or testes
What does the skin produce when exposed to ultraviolet light? - answer>>vitamin D
3 Main layers of the skin - answer>>epidermis (contains melanocytes, which affect skin pigment), dermis
(contains hair follicles, nerve endings, blood vessels, glands), and hypodermic (or subcutaneous layer)
What does the endocrine system regulate? - answer>>all of the body's biological processes in some way,
including metabolism, brain and nervous system function, growth and sexual development, blood cell
formation, appetite, sleep and wake cycles, salt and water balance, reproduction, and response injury or
stress (including the "fight or flight" response)
Where do the nervous and endocrine systems integrate? - answer>>at the hypothalamus in the brain.
The nervous system uses electrical impulses to send signals to the hypothalamus, which secretes
releasing or inhibiting hormones to the pituitary
The pituitary - answer>>acts as a "master gland" by releasing hormones to other parts of the body
,Homeostasis - answer>>the state of maintaining a steady internal environment. A self-regulating
process, it works mainly through negative feedback loops and hormone regulation in response to
changes
Urinary system (main function) - answer>>excretion
Urinary system (main organs) - answer>>kidneys, ureters, urinary bladder, and urethra
Kidneys - answer>>filter blood to remove waste (particularly nitrogenous waste from protein digestion),
manufacture urine, balance body fluids, produce renin to help regulate blood pressure, release the
hormone erythropoietin to stimulate red blood cell formation, and produce active form of vitamin D
Nephron - answer>>functional unit of the kidney. Blood is filtered in the glomerulus, and filtrate is
carried away through the tubule
Ureters - answer>>small tubes that carry urine to the urinary bladder, where it is held until it is released
through the urethra. Males have. longer urethra, which passes through the penis and carries both urine
and semen
Immune system (main function) - answer>>protects the body from pathogens. Two major components:
innate and adaptive
Innate immune system - answer>>a series of nonspecific barriers, consists of both external physical
barriers (skin, hair mucus, earwax) and internal barriers in the form of cellular and chemical responses
(including the inflammatory response, phagocytes, antimicrobial peptides, interferons, and natural killer
lymphocytes) to reduce the number of pathogens that can enter the body or multiply
Adaptive immune system - answer>>both reacts (cellular response; fights pathogens) and remembers
(humoral response; antibodies)
, Lymphocytes - answer>>a white blood cell type that includes T cells (killer and healer) and B cells. When
T cells recognize a pathogen, they activate the B cells, which multiply rapidly and produce antibodies
against specific antigens. B cells then clone into memory cells to be able to recognize the antigen at a
later time.
Passive immunity - answer>>immunity is received from a source outside the body (such as when an
infant has antibodies acquired via the placenta and breast milk).
Active immunity - answer>>natural immunity results when a person is directly exposed to a pathogen
and produces antibodies through the body's immune response
Skeletal system (main function) - answer>>movement, protection, storage of minerals (mainly calcium,
and phosphorous), and lipids
Five bone types - answer>>long, short, flat, irregular, and sesamoid. Bones are attached to other bones
by ligaments and to muscles by tendons
Long bones - answer>>are longer that they are wide. They include the femur, humerus, and many other
bones of the appendicular skeleton. They have hallow shafts containing marrow, which stores lipids
(fats), support the body, and are involved in movement.
Short bones - answer>>are about as wide as they are long and include carpal and tarsal bones
Flat bones - answer>>include the ribs and sternum. They protect vital organs and contain marrow but
are not hallow.
Irregular bones - answer>>vary in size and shape and include the vertebrae and mandible.
Sesamoid bones - answer>>are round, small, and embedded in tendons. They are found in the hands,
feet, and knees (patella).
