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.

    A. Deletion

    B. Insertion

    C. Substitution

    D. Inversion

    Answer Explanation

    The correct answer is choice C. Substitution.

    A substitution mutation is a type of point mutation where one base in the DNA sequence is replaced by another base.

    Choice A is incorrect because a deletion mutation occurs when one or more bases are removed from the DNA sequence.

    Choice B is incorrect because an insertion mutation occurs when one or more bases are added to the DNA sequence.

    Choice D is incorrect because an inversion mutation occurs when a segment of DNA is reversed within the chromosome.

  • Q #2: What is the largest vein in the human body that returns deoxygenated blood from the upper half of the body to the right atrium of the heart?

    A. Superior vena cava.

    B. Inferior vena cava.

    C. Pulmonary vein.

    D. Renal vein.

    Answer Explanation

    The correct answer is choice A.

    The superior vena cava is the largest vein in the human body that returns deoxygenated blood from the upper half of the body to the right atrium of the heart.

    Choice B is incorrect because the inferior vena cava returns deoxygenated blood from the lower half of the body to the right atrium of the heart.

    Choice C is incorrect because the pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart.

    Choice D is incorrect because the renal vein carries deoxygenated blood from the kidneys to the inferior vena cava.
