Summary Introduction
To complete: The table that summarizes the functions of the cells and chemicals of the innate defense mechanisms of mammals.
Introduction: The immune system protects the body from the invading pathogenic organisms. The immune system is classified into two types, namely the innate immune system and adaptive immune system. The innate immune system is the defense mechanism found already from the birth whereas the adaptive immune system is acquired at the later stages of life when exposed to antigens. The white blood cells that involve in innate immunity are natural killer cells, mast cells, eosinophils, basophils, macrophages, neutrophils, and dendritic cells.

- please answer # 1a and 1 1a) LIST and DESCRIBE at least 5 Molecules and Cell types that are shared and interconnect the INNATE Defenses of the body with the ACQUIRED / Adaptive Immunity Include both proteins and signaling ligands. DEFINE the defensive functions of EACH shared component and Use simple DRAWINGS to illustrate the interactions. EXPLAIN HOW they connect the immune and innate pathways.arrow_forwardDescribe the three ways acquired immune tolerance develops in the vertebrate hostarrow_forwardThe classic inflammatory response (heat, swelling, redness, pain) reflects the communication of innate and adaptive defenses. Which of the following is not correct about this response? Group of answer choices Non-cytopathic viruses stimulate the inflammatory response Adjuvants stimulate inflammation and therefore a good antibody response Dendritic cells link the innate and adaptive responses Tumor necrosis factor alpha is a major inducer of inflammation Increased blood flow is one result of inflammationarrow_forward

- What is the defense mechanism called in the question pictured below?arrow_forwardMatch each of the listed characters below to the innate or adaptive immune system. 1) Fully formed at birth 2) Includes barrier tissues and macrophages, among other defenses. 3) Recognizes molecular patterns that are shared across many pathogens. 4) Serves as the first line of defense. 5) Continues to develop with exposure to new pathogens. 6) Recognizes specific (unique) pathogen peptides. 7) Includes a 'memory' that leads to immunity by recognizing threats that have previously invaded the body. 8) Involves T cells, B cells, and antibodies. Here is the options: a) innate immune system. b) adaptive immune system.arrow_forwardThe effector mechanisms that are recruited to clear an infection depend on the infectious agent. In addition to producing distinct innate responses locally at the site of infection, the different cytokines produced during type I, type 2, or type 3 immune responses also induce distinct adaptive immune responses that are tailored to the eradication of the three different classes of pathogens. One example is the production of different classes of antibodies during type I, type 2, or type 3 responses. Which step during the induction of the adaptive immune response is the key to generating and coordinating the three different immune modules?arrow_forward
