19Comparing the endocrine and nervous system Nervous or Endocrine? Fast acting Hormones May last in system for days Neurotransmitters Target cellsNervous Endocrine
20Somatic and Special Senses A stimulus is anything that causes a response.TrueSensory receptors produce stimuliFalse: receive
21Which of the following are examples of sensory adaptation? Not noticing a bad smell after a period of time.Yes- senses tune out the smell to be aware of other odors in the areaYour eyes dilating after entering a dark roomNo- this is a reflexShutting out the sound of the air blower when someone in the class is speaking.Yes
22Match each type of receptor with its stimulus. Pain receptor changes in temperatureChemoreceptor changes in lightThermoreceptor tissue damageMechanoreceptor changes in pressurePhotoreceptor changes in chemicalconcentration
23Which is not a somatic sense? PressureOdorTemperaturePainb.
26Blood and Cardiovascular A function of the cardiovascular system is to transport wastes.True: also nutrient, gases and fluidsThe cardiovascular system is involved in temperature regulation.True.
27Which is not a cellular component of blood? Red blood cellWhite blood cellBlood plasmaPlateletsc. Plasma is the liquid portion of the bloodWhich component of blood helps clot the blood when you get a cut?d. platelets
28The main function of white blood cells is to transport oxygen. Baloney: Red blood cells
29Using blood as a diagnostic tool If you are anemic which type of blood cell count will be low- red or white? Red Are blood cell counts quantitative or qualitative? Quantitative
30How are blood type determined? Antibodies on red blood cells tell us our blood type.Baloney: AntigensThe pH factor determines if we have + or – blood type.Baloney: Rh factor
31Blood transfusionsWhat blood type is the universal donor? O- What blood type is the universal recipient? AB+
33Venule Artery Capillary Vein 2 Arteriole Trace the path of blood through the blood vessels beginning at the heartVenuleArteryCapillaryVein2 Arteriole
34( Arteries / Capillaries ) are a good site for gas exchange because they have thin permeable walls. ( Arteries / Veins ) have thick walls that withstand the high pressure of blood as it is pumped from the heart.Which is a more worrisome blood pressure?140/ 100100/60
35What is the name of this graph? EKGWhich pattern is normal?
36Lymphatic and Immune Systems Which of the following is not part of the lymphatic system?a. Lymphb. Lymph junctionsc. Lymph nodesd. Lymph vesselsb.
37Lymphatic structures WORD BANK Lymph node Lymph vessel Right lymphatic ductSpleenThoracic ductThymusTonsils
38Lymph comes froma. Tissue fluidsb. Organ fluidsc. Digestive fluidsd. Reproductive fluidsa.
39Which is not true about lymph nodes. a. They filter lymphb. Serve as production site for antibodiesc. Remove phagocytized materiald. Produce red blood cellsd.
40Specific defenses against disease include species resistance, mechanical barriers, fever and inflammation.Baloney: Nonspecific defensesThe immune system can attack foreign invaders.True
41(Before birth / After birth ) the body determines what is self and non-self. Macrophages attack cells which display (antibodies / antigens ) that are non-self.Once macrophages enter the lymph system,( Killer T-cells / Helper T-cells ) are activated.Helper T-cells call out B cells to produce ( histamines / antibodies ) that inhibit the spread of the infection.Killer T-cells ( destroy / isolate ) the infection.Suppressor T-cells control ( killer T-cells / the infection ).Some B-cell and Killer T-cells become (suppressor T-cell/ memory cells).
42An example of natural immunity is a vaccine. Baloney: acquiredAllergies are normal responses to foreign invaders.Baloney: abnormalEpinephrine is used to treat severe allergic reactions.True

53Urinary SystemThe kidneys filter blood to remove ( wastes / nutrients )The vas deferens and urethra are tubes in the male that transport ( urine / sperm ).The renal corpuscle and renal tubule are found in the ( bladder / kidney ).
54The renal corpuscle( filters / selectively reabsorbs ).The function of the urinary system is to maintain ( homeostasis / hematopoiesis ).
56Which blood vessel is bringing unfiltered blood into the nephron? 12- This is the afferent arterioleStructure 1 is the site of filtration. What is the name of this structure?GlomerulusWhat is the name given to the substances filtered from the blood and found in structure 3?FiltrateTogether structures 1 and 3 are called the?Renal corpuscleNephron
