What is a clear, watery fluid found in the anterior and posterior chambers of the eye? A. Vitreous humor B. Ciliary body C. Lacrimal gland D. Aqueous humor Answer: D Rationale: Aqueous humor is a clear, watery fluid similar in composition to blood plasma and is commonly found in the anterior and posterior chambers. The posterior cavity, located dorsal to the lens, contains the (A) vitreous humor, a thick, clear, gelatinous fluid. The (B) ciliary body is the structure of the eye that releases the aqueous humor. The (C) lacrimal gland continually secretes tears which moisten, lubricate, and protect the surface of the eyes. 2. What is correct about the aqueous humor? A. It balances absorption and pressure in the anterior chamber B. It is secreted by the epithelium of the ciliary bodies C. Its inability to circulate freely can cause elevated intraocular pressure D. All of the above Answer: D Rationale: All three choices describe how the aqueous fluid forms and circulates in the eye. The aqueous humor’s inability to absorb could develop into an increased intraocular pressure which may lead to blindness when the pressure is transmitted to the vitreous humor. 3. All of the following are phagocytes EXCEPT: A. Neutrophil B. Lymphocytes C. Eosinophil D. Monocytes Answer: B Rationale: (A) Neutrophils are capable of phagocytosis, or destruction of bacteria. (B) Lymphocytes offer mediate immune responses, including antigen-antibody reactions. (C) Eosinophils are phagocytes that protect you from parasites. (D) Monocytes are phagocytes that defend against bacteria and viruses.
