Clot and scab formation occur as part of this process: Group of answer choices   cytolysis hematopoiesis phagocytosis inflammation

The circulating cytokines that recruit large numbers of phagocytes to the area of inflammation, resulting in pus, are called: O1) pyogens O 2) pyrogens 3) interferons O 4) defensins

A patient develops a blood infection with a capsule-producing strain of E. coli. Phagocytosis by macrophage will be essential to destroy the bacteria and resolve the infection. Which of the following will be dirertly required to allow ADCC-opsonization of the encapsulated E. coli: O Toll-like receptor (TLR)-induced secretion of tumor necrosis factor alpha O Release of C3a to the extracellular fluids O Presence of MHC II on the surface of the macrophage O Presence of IgG receptors (Fc-gamma-R) on the macrophage All of the answers apply

Epithelial surfaces provide the first line of defense against infection by the use of several types of mechanisms. One of the chemical mechanisms used by epithelia is: Joining of epithelial cells by tight junctions Secretion of antimicrobial peptides by epithelial cells Production of mucus, tears, or saliva in the nose, eyes, and oral cavity Movement of mucus by cilia Peristalsis in the gastrointestinal tract

Which of the following is not a function of eosinophils? Phagocytosis Antigen presentation Production of cytokines Antibody production Release of cytotoxic granule proteins

The first cells which respond to penetration of the skin by a penetrating thorn are:     immune cells   keratinocytes   neurons

Which one of the following is a white blood cell that can target cell death of parasites?  Group of answer choices Monocyte Eosinophil Mast cell Plasma cell

For each of the following scenarios: 1. State the division of the ANS that is represented 2. Draw in the specific neurotransmitter released in the synapse between the pre- and post-ganglionic neurons 3. Draw in the specific neurotransmitter released in the synapse with the target tissue (effector) 4. Draw in the type of receptor on the post-ganglionic neuron 5. Draw in the type of receptor on the target tissue (effector) 6.
