QUESTION 21 Select the incorrect pairs. focal infection - infection remains in a specific tissue. Systemic infection - infection spreads to several sites and tissue fluids. Horizontal transfer or transmission - disease spread through a population from one person to another Prodromal stage of an infection - period after period of invasion. Biological vector - arthropods like mosquitoes. sequelae - long-term or permanent damage to tissues or organs caused by an infectious disease.

Answer 1

Answer:-

(21) The correct option is sequelae - long term or permanent damage to tissues or organs caused by an infectious disease.
Because sequelae is a pathological condition resulting from a prior disease, injury, or attack.

(22) The correct option is Sensitized Rh- mother pregnant with Rh+ second baby.
Because hemolytic disease of the newborn most frequently occurs when an Rh negative mother has a baby with an Rh positive father.

(23) The correct option is macrophages, neutrophils and monocytes are all phagocytes.
Because only macrophages & neutrophils are phagocytes.

(24) The correct option is coughing and sneezing.
Because the first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, 'friendly' bacteria and white blood cells called neutrophils.

(26) The correct option is opsonization.
Because opsonization is the molecular mechanism whereby pathogenic molecules, microbes, or apoptotic cells (antigenic substances) are connected to antibodies, complements, or other proteins to attach to the cell surface receptors on phagocytes and NK cells.
