A. TrueA. TrueQuestion 99 out of 10 pointsWhich of the following statements regarding blood pressure are true and which are false?QuestionCorrect MatchSelected MatchIf BP decreases, filtration in the kidneys will increase tocompensate.B. FalseB. FalseNormal systolic pressure created by the right ventricle is about 120 mmHg.B. FalseB. FalseBlood pressure in capillaries is lower than in the arterioles, and increases in the venules.B. FalseB. FalseThe outer layer of the walls of arteries can contract or relax to change BP.B. FalseB. FalseThe carotid and aortic sinuses contain pressoreceptors that detect changes in BP.A. TrueA. TrueThe arteries provide peripheral resistance, which depends on parasympathetic impulses.B. FalseB. FalseIf BP decreases as a result of hemorrhage, heart rate will increase and more vasoconstriction will occur.A. TrueA. TrueADH and aldosterone both help maintain or raise BP bycausing vasoconstriction.B. FalseB. FalseBP is regulated by the vasomotor center in the medulla.A. TrueA. TrueThe renin-angiotensin mechanism prevents kidney damage by lowering BP if it becomes too high.B. FalseA. TrueQuestion 108 out of 8 pointsMatch the lymph nodes and nodules with their proper locations and functions.
QuestionCorrect MatchSelected MatchBelow the epithelium of all mucous membranesB. Lymph nodulesB. Lymph nodulesAlong the pathways of lymph vessels.A. Lymph nodesA. Lymph nodesMajor paired groups include cervical and inguinalA. Lymph nodesA. Lymph nodesIn the pharynx, they are called tonsilsB. Lymph nodulesB. Lymph nodulesDestroy pathogens in the lymph from the extremities before the lymph is returned to the bloodA. Lymph nodesA. Lymph nodesPlasma cells produce antibodies that will enter thebloodA. Lymph nodesA. Lymph nodesDestroy pathogens that penetrate mucous membranesB. Lymph nodulesB. Lymph nodulesPlasma cells produce antibodies that act locally in mucous membranesB. Lymph nodulesB. Lymph nodulesQuestion 11Needs GradingReference Figure 14-3: State the seven major PAIRED groups of lymph nodes. Why are these nodes located in or near the head and extremities?Selected Answer:submaxillary nodes, cervical nodes, axillary nodes, cubital nodes, Iliac nodes, Inguinal nodes, popliteal nodes. Breaks in the skin, with entry of pathogens, are much more likely to occur in the arms or legs or head rather than in the trunk. If these pathogens get to thelymph, they will be destroyed by the lymph nodes before they get to the trunk and before the lymph is returned to the blood in the subclavian veins. Correct Answer:Submaxillary nodes; Cervical nodes; Axillary nodes; Cubital nodes; Iliac nodes; Inguinal nodes; Popliteal nodes. Breaks in the skin, with entry of pathogens, are much more likely to occur in
the arms or legs or head rather than in the trunk. If these pathgens get to the lymph, they will be destroyed by the lymph nodes before they get to the trunk and before the lymph is returned to the blood in the subclavian veins.
