NPB 101 MIDTERM 1 Exam Questions
and Answers Graded A+
levels of organization - Correct answer-cell --> tissue --> organ --> organ system --
> organism
Cell - Correct answer-obtains nutrients/oxygen, exchange of materials, intracellular
transport, metabolism, synthesis, reproduction
4 primary types of tissue - Correct answer-1) muscle (contractions. skeletal,
cardiac, smooth)
2) nervous (signals. central and peripheral)
3) epithelial (exchange. epithelial sheet that form boundaries and glands for
secretion (exocrine for external secretion and endocrine for internal secretion)
4) Connective (structural support. tendons, bones, blood)
Organ - Correct answer-2 or more primary tissues organized to perform a function
stomach composition - Correct answer-epithelial (sheet for barrier to digestive
juices, exocrine gran to secrete digestive juices and endocrine gland to regulate

,exocrine secretion), muscle (smooth for the wall), nervous (peripheral nerves to
regulate contraction) and connective (structural support)
circulatory system - Correct answer-hear, blood vessels, blood. transports nutrients,
wastes, electrolytes, hormones, etc.
digestive system - Correct answer-mouth, pharynx, esophagus, stomach, small
intestine, large intestines, salivary glands, pancrease. obtains nutrients, water,
electrolytes and transfers them into plasma
respiratory system - Correct answer-nose, pharynx, larynx, trachea, bronchi, lungs.
obtains oxygen and eliminate co2. regulate ph
urinary system - Correct answer-kidneys, uteters, urinary bladder, urethra. ph of
internal environment regulate volume, electrolyte composition
skeletal system - Correct answer-bones, cartilage, joints.
muscular system - Correct answer-skeletal muscles. heat generating muscle
contraction used in temp regulation
immune system - Correct answer-white blood cells, thymus, bone marrow, tonsils,
adenoids, lymph nodes, spleen, appendix, gut associated lymph tissue, skin
associate lymph tissue. defends against foreign invaters

, integumentary system - Correct answer-skin, hair, nails. protective barrier between
external environment and remainder of body. sweat glands, temp regulation
nervous system - Correct answer-brain, spinal cord, peripheral nerves, sense
organs. electrical signals to control rapid response and higher funtions. uses
neurotransmitters as chemical messengers. wired
endocrine system - Correct answer-hormone secreting tissues, hypothalamus,
pituitary, thyroid, adrenals, endocrine pancreas, parathyroids, gonads, kidneys,
intestine, heart, thymus, pineal, skin. hormone secretion to control processes that
require duration rather than speed. wireless. specificity of action dependent on
specificity of target cell binding and responsiveness to particular hormone.
generally slow and long action
reproductive system - Correct answer-male = testes, penis prostate gland, seminal
vesicles, bulbourethreal glands
female = ovaries, oviducts, uterus, vagina, breasts.
claude bernard - Correct answer-french physiologist. recognized that the
specialized integuments of higher oranisms effectively created an internal
environment that can be controlled independently form outside fluctuations.
