What is the main function of the integumentary system? - -Protection, temperature
regulation, and sensation.
Which organs are part of the integumentary system? - -Skin (epidermis, dermis,
subcutaneous), hair, nails, glands.
What is the primary role of the musculoskeletal system? - -Support, movement, and
protection.
Name the major components of the musculoskeletal system. - -Bones, muscles, joints,
ligaments, tendons.
What does the nervous system control? - -Voluntary and involuntary actions.
Identify the main parts of the nervous system. - -Central Nervous System (CNS) and
Peripheral Nervous System (PNS).
What is the primary function of the respiratory system? - -Gas exchange (oxygen in,
carbon dioxide out).
List the key organs involved in the respiratory system. - -Nose, diaphragm, trachea,
bronchi, lungs.
What is the main function of the digestive system? - -Breakdown and absorption of
nutrients, elimination of waste.
,Which organs are part of the digestive system? - -Mouth, esophagus, stomach, intestines,
liver, pancreas.
What does the urinary system do? - -Eliminates liquid waste and regulates fluid balance.
Identify the major organs of the urinary system. - -Kidneys, ureters, bladder, urethra.
What is the primary function of the circulatory system? - -Transport of blood, nutrients,
wastes, and hormones.
Name the key components of the circulatory system. - -Heart, blood, arteries, veins,
capillaries.
What is the role of the immune system? - -Defense against infection and disease.
List the main components of the immune system. - -White blood cells, lymph nodes,
thymus, spleen, bone marrow.
What does the lymphatic system support? - -Fluid balance and immune function.
What is the function of the endocrine system? - -Hormone production and regulation of
body functions.
Identify the major glands of the endocrine system. - -Pituitary, thyroid, adrenal, pancreas.
What is the primary role of the reproductive system? - -Production of offspring.
,Name the male reproductive organs. - -Testes and penis.
List the female reproductive organs. - -Ovaries, fallopian tubes, uterus, vagina.
What is the structure of the heart? - -Composed of four chambers: right atrium, left
atrium, right ventricle, left ventricle.
What regulates blood flow in the heart? - -Four main valves: tricuspid, pulmonary, mitral
(bicuspid), and aortic valves.
What are the three main types of blood vessels? - -Arteries, veins, and capillaries.
What is the function of arteries? - -Carry oxygen-rich blood away from the heart.
What is the role of veins? - -Return deoxygenated blood back to the heart.
What is the purpose of capillaries? - -Allow exchange of oxygen, nutrients, and waste
products between blood and tissues.
What are the two main types of circulation? - -Pulmonary and systemic circulation.
What does pulmonary circulation do? - -Moves deoxygenated blood from the heart to
the lungs for gas exchange.
What is blood pressure? - -The force of blood against the walls of the arteries, measured
as systolic and diastolic.
, What is the normal adult blood pressure? - -Around 120/80 mmHg
What role do nursing assistants play in circulatory health? - -They measure and record
vital signs, observe symptoms of poor circulation, and help position and mobilize patients.
What are common signs of poor circulation? - -Cold or bluish extremities, swelling
(edema), fatigue, shortness of breath, and irregular or weak pulse.
What is hypertension? - -High blood pressure
What is atherosclerosis? - -Narrowing of arteries due to plaque build-up.
What is heart failure? - -The heart's inability to pump blood effectively.
What are the primary functions of the urinary system? - -Filtering blood to remove waste
products, regulating fluid and electrolyte balance, and maintaining acid-base homeostasis.
What organs make up the urinary system? - -Kidneys, ureters, bladder, and urethra.
What is the process of urine formation? - -Filtration, reabsorption, and secretion.
What are normal characteristics of urine? - -Color: Pale Yellow to Amber, Clarity: Clear,
Odor: Mild, Volume: Approximately 1,000 to 2,000 milliliters per day.
What are common urinary system disorders? - -Urinary Tract Infections (UTIs), urinary
incontinence, and kidney stones.
