2:37A UniSA App Biology B Week 8 Tutorial ייו 63 Done Biology B Tutorial Six - Immune System Tutorial 6 (Week 8) - Immune System The immune system is an incredibly complex system which has evolved to protect us from both extrinsic as well as intrinsic threats. It is remarkably efficient and protects us day in and day out from the onslaught of pathogens we regularly face. It consists of two broad arms, the very fast to respond but predominantly non-specific innate immune system, and the highly specific, slower to respond but more effective when it does, adaptive immune system. Both arms have their advantages and disadvantages, and together they have achieved in mammals a very efficient suite of protective mechanisms. 1. Define the terms 'antigen' and 'antibody'. 2. What is the purpose of having a lymphatics system? 3. Innate and Adaptive immunity are the two arms of the vertebrate immune system and in humans, a suite of cells contributes to each arm. In one sentence per cell type…

An antigen acts is a molecule that acts like a name tag, allowing the immune system to recognize the cell it is attached to. The name tag might say: "Hello I'm... a deadly virus," or “Hello I'm... a healthy human cell." It is very important that an antigen for a deadly virus and a healthy human cell are very different, so that the immune system does not make a mistake and attack healthy human body cells. Which of the following molecules do you think would make good antigens for recognizing a pathogen? Justify your answer. You may choose more than one. 1) a cell wall protein 2) a piece of DNA inside a cell 3) a protein that is part of a flagella 4) a uniquely shaped protein that is part of a virus 5) a protein that is only made by prokaryotic cells 6) a protein that is only made by eukaryotic cells

One of the following doesn't cause inflammations and so doesn't induce immune response of the body. * O necrosis apoptosis pathogen entry to the body bacterial infection viral infection O O O

Which one of the following statements regarding our innate immune system is false?   Question 15 options:   The normal flora takes up space so that pathogenic microbes can't grow.   The skin prevents entry of microbes into the body.   Coughing speeds up the ciliary escalator, while smoking can destroy it.   Phagocytosis destroys microbes that have escaped our physical and chemical barriers.   Macrophages create antibodies against specific microbes.

Which of the following is true about the immune system? Check all that apoply. Rejecting  organs or bone marrow transplantation is the normal function of the immune system Overreaction of the immune system to cause allergy or causing autoimmune diseases is normal function of the immune system Immune system discriminates between self and non-self Immune system eliminates infectious agents but not cancer from the human body Eliminating infectious agents and cancer are the normal functions of the immune system

Body Systems The human immune system consists of a network of cells, tissues, and organs. The cardiovascular system consists of the heart, blood vessels, and blood. How do the immune and cardiovascular systems work together to protect the human body? OA. The immune cells send electrical signals through the blood to the brain. OB. The two systems allow for the exchange of gases between the blood and the rest of the body. OC. The blood acts as a medium for the transportation of immune cells throughout the body. OD. The two systems allow for the storage of nutrients to fuel the body at a later time. Reset Submit

What is an antigen? O The bad guy in a movie. Any foreign object that elicits an immune response. Proteins on white blood cells. Defense proteins the liver produces.

5.Statement 1: The cell-mediated immune response is brought about by T cells. Statement 2: In humoral immunity, some B cells become memory cells which are long-lived cells that can recognize an antigen that once already infected the body. Note: This is a multiple question, choose the correct answer below: Statement 1 is true. Statement 2 is false. Statement 2 is true. Statement 1 is false. Both statements are true. Both statements are false.

QUESTION 2 Which statement best describes autoimmune diseases? A condition in which B and I cels trigger anaphylactic shock in response to an antigen A condition in which self molecules are treated as non-self A condition in which the adaptive immune system fails to recognize the second infection by the same pathogen A condition in which the immune system creates random antibodies

Match the following principles to its respective concepts. Match each item to a choice: Innate Immune System Immune System Adaptive Immune System Choices: : Physiological System for Infection Control : Protective Barriers for Infection : Prolonged Protection for Infection

12. Why do we have an immune system? Why do we need an immune system?

Body Systems Antigens are cellular parts that are able to bind to antibodies. Antigens are usually made out of proteins or polysaccharides, so they include parts like the coats, capsules, or cell walls of pathogens (disease-causing bacteria, viruses, and other microorganisms). Antibodies are proteins that are produced by the immune system to prevent the growth and spread of pathogens. Antibodies bind to antigens, like keys fitting into specific locks.

Name 4 characteristics of the innate immune response

The immune system can be split into two major categories, the innate immune system and the adaptive immune system. Compare and contrast these two systems and their response to a bacterial pathogen that entered the body through a cut in the skin.  In your answer describe two ways in which the innate immune system protects against this pathogen, as well as two ways that the adaptive immune system protectS against this pathogen. Be sure to name any cells/organs/tissues/structures that may be involved  in each of these processes in order to receive full marks. This can be done as a list in point form.
