The Lymphatic System Essay
A. What was the intent of making this exercising? The intent of this exercising was to larn about the lymphatic system and its constituents. We learned about lymph. construction and map of lymph nodes. T-Cells. B-Cells. and Macrophages. and distinguishing between antigens and antibodies.
Exercise 1: Microscopic Anatomy of Lymphatic Structures
A. Sketch of Reticular Connective Tissue Slide ( Lymph Node ) . Describe the constructions you observed on the slide.
B. Sketch of Spleen Slide: Describe the constructions you observed on the slide.
C. Sketch of Tonsil Slide: Describe the constructions you observed on the slide.
D. Sketch of Thymus Slide: Describe the constructions you observed on the slide.
Exercise 2: Unsusceptibility and the Immune Respose
A. Describe what happened to the ruddy and green nutrient colouring after 45 proceedingss. The nutrient colourising spread throughout some of the dish.
B. Which sera was an antigen in subdivision 2 of the dish? Describe what you observed in subdivision 2 of the dish. After 3 yearss. there was no seeable line of precipitation evident and hence the consequence is inconclusive.
C. Which sera was the antigen in the “unknown” sample used in subdivision 3 of the dish? Describe what you observed in subdivision 3 of the dish.
After 3 yearss. there was no seeable line of precipitation evident and hence the consequence is inconclusive.

Questions Exercise 1: Microscopic Anatomy of Lymphatic Structures
A. How are lymph. lymphatic vass and lymph nodes related? Lymph. lymphatic vass and lymph nodes are all portion of the lymphatic system. Lymph vass carry lymph throughout the organic structure. Throughout the vessles are lymph nodes which fight infection.
B. What are the two major maps of the lymph nodes? They clean and filter lymph before it goes back to the blood. They produce antibodies and lymph cells.
C. What are the two maps of the lien? It protects the organic structure and helps to bring forth and hive away blood cells.
D. What is the map of the tonsils? They protect the organic structure from harmful sources.
E. What are the structural similarities found in lymph nodes. lien and tonsils? They all have a capsule and are rounded variety meats with an internal parenchyma of lymphoid cells.
Exercise 2: Unsusceptibility and the Immune Response
A. Explain what is meant by “memory” as a feature of the immune response. When the organic structure comes in contact with a harmful antigen. it has a primary response. which remembers the antigen by making memory cells. By the secondary response. the memory cells will antagonize the antigen.
B. How does our immune response distinguish between our ain cells and foreign encroachers? A major histocompatibility composite is at the surface of each cell in our organic structure. It is what recognizes if something is foreign or non. and lets the immune system know. B. What are lymph cells and where are they produced? Lymphocytes are a type of white blood cell that protect the organic structure from infection. They are produced in the bone marrow.
C. Distinguish between an antigen and an antibody. An antigen is a foreign stuff that enters the organic structure. and an antibody is what recognizes the foreign stuff and helps contend it.
