A. True A. True Question 9 9 out of 10 points Which of the following statements regarding blood pressure are true and which are false? Question Correct Match Selected Match If BP decreases, filtration in the kidneys will increase to compensate. B. False B. False Normal systolic pressure created by the right ventricle is about 120 mmHg. B. False B. False Blood pressure in capillaries is lower than in the arterioles, and increases in the venules. B. False B. False The outer layer of the walls of arteries can contract or relax to change BP. B. False B. False The carotid and aortic sinuses contain pressoreceptors that detect changes in BP. A. True A. True The arteries provide peripheral resistance, which depends on parasympathetic impulses. B. False B. False If BP decreases as a result of hemorrhage, heart rate will increase and more vasoconstriction will occur. A. True A. True ADH and aldosterone both help maintain or raise BP by causing vasoconstriction. B. False B. False BP is regulated by the vasomotor center in the medulla. A. True A. True The renin-angiotensin mechanism prevents kidney damage by lowering BP if it becomes too high. B. False A. True Question 10 8 out of 8 points Match the lymph nodes and nodules with their proper locations and functions.

Question Correct Match Selected Match Below the epithelium of all mucous membranes B. Lymph nodules B. Lymph nodules Along the pathways of lymph vessels. A. Lymph nodes A. Lymph nodes Major paired groups include cervical and inguinal A. Lymph nodes A. Lymph nodes In the pharynx, they are called tonsils B. Lymph nodules B. Lymph nodules Destroy pathogens in the lymph from the extremities before the lymph is returned to the blood A. Lymph nodes A. Lymph nodes Plasma cells produce antibodies that will enter the blood A. Lymph nodes A. Lymph nodes Destroy pathogens that penetrate mucous membranes B. Lymph nodules B. Lymph nodules Plasma cells produce antibodies that act locally in mucous membranes B. Lymph nodules B. Lymph nodules Question 11 Needs Grading Reference 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 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. 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.
