What is the function of inflammatory cytokines released during the early response to bacterial infection?

A. Enhancing the phagocytosis of pathogens and disrupting the infection

B. Attacking invading pathogens

C. Initiating cell recruitment and local inflammation

D. Secreting antibodies to neutralize pathogens .

Answer Explanation:

Inflammatory cytokines released during the early response to bacterial infection play a crucial role in initiating cell recruitment and local inflammation 1.

They induce the expression of adhesion molecules in endothelial cells and promote the recruitment of neutrophils to the site of inflammation 1.

Choice A is incorrect because while inflammatory cytokines may enhance phagocytosis, they do not directly disrupt the infection.

Choice B is incorrect because inflammatory cytokines do not directly attack invading pathogens.

Choice D is incorrect because inflammatory cytokines do not secrete antibodies to neutralize pathogens.

Therefore, the Correct Answer is C.

  • Q #1: Which of the following is a consequence of increased viscosity of a fluid?

    A. Particles have a decrease in mobility.

    B. The fluid will have a lower density.

    C. The fluid will have a higher flow rate.

    D. The fluid will have a higher pressure.

    Answer Explanation

    The correct answer is choice A.

    An increase in viscosity of a fluid results in a decrease in mobility of particles.

    Viscosity is the resistance of a fluid to a change in shape or movement of neighboring portions relative to one another.

    It denotes opposition to flow and may be thought of as internal friction between the molecules.

    Choice B is incorrect because an increase in viscosity does not affect the density of a fluid.

    Choice C is incorrect because an increase in viscosity results in a decrease, not an increase, in flow rate.

    Choice D is incorrect because an increase in viscosity does not affect the pressure of a fluid.

  • Q #2: Which hormone is responsible for the development of female secondary sexual characteristics such as breast development, menstrual cycle, and widening of hips?

    A. Progesterone

    B. Testosterone

    C. Estrogen

    D. FSH

    Answer Explanation

    The correct answer is choice C. Estrogen.

    Estrogen is a steroid hormone responsible for the development of female secondary sexual characteristics such as breast development, menstrual cycle, and widening of hips.

    Choice A, Progesterone, is not the correct answer because it is required to maintain pregnancy and delivery.

    Choice B, Testosterone, is not the correct answer because it is a hormone produced by the testes which controls the development of male secondary sexual characteristics.

    Choice D, FSH (Follicle Stimulating Hormone), is not the correct answer because it stimulates the growth of ovarian follicles in females and regulates spermatogenesis in males.

  • Q #3: Which of the following structures in the nephron is responsible for reabsorbing ions, water and nutrients?

    A. Distal tubule

    B. Proximal tubule

    C. Glomerulus

    D. Loop of Henle

    Answer Explanation

    Proximal tubule

    The proximal tubule is responsible for reabsorbing all the nutrients and most of the water.

    Choice A is incorrect because the distal tubule is not primarily responsible for reabsorbing ions, water and nutrients.

    Choice C is incorrect because the glomerulus is responsible for filtering fluid and solutes out of the blood to form a glomerular filtrate.

    Choice D is incorrect because the Loop of Henle is not primarily responsible for reabsorbing ions, water and nutrients.
