LYMPH AND IMMUNE SYSTEM WB OLA (6)

Lymphatic System - Function and Non-Function : Goal Cancer of the Lymphatic System is a very anatomically and physiologically degrading illness. Given the fact that the Lymphatic system is found throughout most of the Human Body, and by this time, you should be very familiar with this system, it is your assignment to respond to the following: ASSIGNMENT #7 Specifically, throughout life, how can a person strive to minimize the potential infection of cancerous invasions in the Lymphatic System and to keep it strengthened? Be accurate, clear, concise, and well-thought!

proteins The lymphatic system serves to collect excess and system, more specifically through the veins in the shoulders. return it to the digestive blood Once tissue fluid has entered the lymphatic vessels, it is called valves lymphatic lymph The movement of lymph within the vessels is dependent on muscle contraction. subclavian cardiovascular When the muscles contract, lymph is squeezed past preventing backflow. smooth tissue fluid Lymphatic vessels also serve to take up at the skeletal tract and transport it to veins. fat

True or false Lymph nodes are equally distributed around the body. Lymphoid tissue is largely composed of dense regular connective tissue. Lymphocytes are first made in the bone marrow The thymus shrinks as we age Lymph is propelled by the heart Lymph contains few white blood cells

Which of the following is NOT a basic function of the lymphatic system? maintain blood pressure transport proteins, fats, and other macromolecules transport immune cells like white blood cells or T lymphocytes make sure all the fluid in the body is equally distributed

Lymphoid organs are divided into primary and secondary peripheral organs. Briefly describe thymus gland and lymph node and their main role(s) in the immune system.

Which of the following statements about lymphatic capillaries is FALSE? Group of answer choices Minivalves prevent the backflow of fluid into the interstitial spaces The endothelial cells are anchored by filaments to the surrounding structures They are located near blood capillaries They collect red blood cells that have "leaked" out of blood vessels

Which of the following is NOT true about the lymphatic system?   the vessels of the lymphatic system form a closed loop   the lymphatic system absorbs excess fluids from the tissue fluid   the lymphatic vessels can be found within capillary beds   movement of fluids within is caused by skeletal muscle motion   lymphatic vessels have a structure similar to veins

The right lymphatic duct drains the lymph from: the entire right side of the body only the right side of the head and neck and right upper limb O the right side of the thorax, right upper limb, and right side of the head and neck only the right side of the thorax the right side of the thorax, the abdomen, and the right lower and the right upper limbs

The lymphatic tissues/organs illustrated below contain which of the following types of cells? 1.  reticular cells 2.  macrophages 3.  B lymphocytes 4.  T lymphocytes Choose from the following: (A) 1, 2 and 3 (B) 1, 2, and 4 (C) 2, 3, and 4 (D) 1, 3, and 4 (E) 1, 2, 3, and 4

T lymphocytes are characteristically found in all of the following locations EXCEPT

Which of the following statements is NOT TRUE about Macrophages?     Macrophages have a single, somewhat large nucleus and granular inclusions     Macrophages serve as antigen presenting cells or APCs     Macrophages can express both MHC I and MHC II when acting as an APC     Macrophages have less surface area than dendritic cells have, to bind antigens     Macrophages arise from the same cell as dendritic cells     Resident macrophages are found in only certain, specific tissues

The Lymphatic System does all of the following except which one of these?   Question 9 options:   Maintain pH balance   Return interstitial fluid and protein to the blood   Filter and destroy unwanted material from the body fluids   Initiate an immune response

Colouring, labelling and matching 1. Fig, 6.1 shows the main structures of the lymphatic system. Label the structures indicated using the key choices listed. Left subclavian vein Key choices: Inguinal nodes Lymphatic vessels of the lower limb Palatine tonsil Thoracic duct (twice) Right subcvien vein Lymph follicles of the small intestine (Peyer's patches) Submandibular nodes Cisterna chyli Intestinal nodes Large intestine Axillary nodes Right lymphatic duct Lymphatic vessels of the upper limb Iliac nodes Popliteal nodes Cervical nodes 2. On Fig. 6.1, colour and label the spleen, red bone marrow of the right femur and the thymus gland different colours, using the key below. O Spleen O hymus gland O Red bone marrow O Area drained by the O Area drained by the

Antibodies don't kill any pathogen directly. Describe FIVE different ways that antibodies help our body fight diseases.

What is the function of the lymph nodes?

Which of the following structures defend against pathogens by acting as a blood filter?     lymph node     thymus     spleen     tonsils     red marrow

Red pulp Lymph node Thoracic duct Cisterna chili Afferent vessel Right lymphatic duct Lymph Medullary cords Efferent vessel White pulp : drains lymph node. : lymphocytes deep in node. : saclike region of the thoracic duct. : empties into right subclavian vein. : splenic tissue containing red blood cells. : full of macrophages and lymphocytes. empties into left subclavian vein. : lymphocytes surrounding central arteries. : fluid in lymph vessels. : empties into lymph node.

Part E - Characteristics of Lymphocytes Drag and drop the correct type of immunity on the left to complete the sentence that describes the targets, actions, or cell associated with that type of immunity. Immunity types may be used more than once, but each sentence has only one correct type of immunity associated with the description. View Available Hint(s)

Macrophage, dendritic cells, T-cells, and B-cells are all considered cells of the adaptive immune system. All these cells come in different varieties.  Still there are some basic processes and interactions between them to generate the appropriate adaptive immune response and defeat the pathogen. Which white blood cell above is not a phagocyte but is an antigen-presenting cell?

Familiar symptoms like high temperature and swelling are processes to aid in the immune response the immune response provides another benefit it’s helps us to develop__________ immunity  antibodies  blood  leukocytes  long-term  macrophages

Secondary lymphoid organs, such as the lymph nodes, spleen, and mucosa-associated lymphoid tissues, each have distinct features that are important for their role in initiating immune responses focused on different anatomical compartments (i.e., the peripheral tissues, the blood, or the gastrointestinal tract, respectively). Yet these organs share some overall structural features, such as distinct T-cell and B-cell zones. One major difference between these organs is: The presence versus the absence of macrophages and dendritic cells Their function in bringing rare naive lymphocytes into contact with their specific antigen The ability of lymphocytes to enter the organ from the blood The mechanism by which antigens or pathogens enter the organ The ability of naïve T cells to be activated and proliferate in the organ

List the similarities and differences between the following terms: B lymphocyte and T lymphocyte

You are a water molecule in the interstitial fluid, you get sucked into the lymphatic system, place the structures through which you will pass in the correct order. into the blood lymphatic duct lymhpatic trunk lymphatic capillary  afferent lyjmphatic vessel lymph node efferent lymphatic vessel

An important aspect of the immune system is the physical separation of the blood lymphatics, extracellular fuld and reticuloendothelial system, so that cells and chemicals of the immune system are isolated from one another True or False

Which of the following is a protein involved with the innate immune response? eosinophil Immunoglobulin M fibrin lysozyme
