Title: BTEC Applied Science Unit 11 Assignment 5
Description: Unit 11: Physiology of Human Body Systems assignment 5 The lymphatic system Task 1 Make a poster to show the positions of lymph vessels, spleen, thymus gland, tonsils. Annotate the poster with the functions of each of the different components. Outline the two roles of the lymphatic system. This provides evidence for P7 Task 2 Explain the specific function of the lymphatic system and the Spleen in the Immune System. It might help if you describe how T & B lymphocytes are involved in the body’s response to infection. You must describe the events that occur following an infection. This provides evidence for M5 Task 3 Investigate two diseases where the lymphatic system is not functioning as it should and compare with a normal functional lymphatic system with good health. It would be a good idea to discuss how the immune system functions normally and discuss numbers of immune cells present in health and disease. This provides evidence for D3 Exam board is Pearson ALL ASSIGNMENTS I HAVE UPLOADED ARE DISTINCTION GRADED.

The primary function of the lymphatic system is to transport lymph that helps rid the body of toxins,
waste products and other unwanted materials

Unit 11- Assignment 5- M5
The primary function of the lymphatic system is to transport lymph that helps rid the body of toxins,
waste products and other unwanted materials
...
The immune system can
identify numerous threats, such as viruses, bacteria and parasites
...
Lymph nodes: Lymph nodes are small, bean-shaped structures
...
Lymph nodes also contain lymph, the clear fluid that carries those cells to different
parts of the body
...
Spleen: The spleen is the largest lymphatic organ in the body
...
The spleen also controls the amount of blood in the body and recycles old or
damaged blood cells
...
The spongy tissue
inside some bones contains stem cells
...
Lymphocytes are small white blood cells which defend the body against disease
...
B-cells and T-cells
...
T-cells
help destroy infected or cancerous cells
...
Helper T-cells help determine which immune responses the body
makes to a specific pathogen
...
It can trigger or maintain the production
of antibodies that can result in muscle weakness
...
Lymphocytes
Small leucocytes with little cytoplasm and spherical nuclei, which originate from stem cells in the
bone marrow
...
Lymphocytes can only be
activated by one particular antigen
...
B-cells produce antibodies
...
Helper T-cells: Help the humoral response by involvement in the maturation of B-cells and by
triggering the production of antibodies by B-cells
...

...
3
...
Virus attaches to and enters the host
...
Killer T-cell attaches to viral antigen on infected cell
...
Killer T-cells and cancer:
1
...
3
...
As cell becomes cancerous, mutations take place
...
Killer T-cell binds to abnormal antigens
...
Memory T-cells: Work in the same way as the memory B-cells, ensuring rapid response on
subsequent exposure to the same non-self antigens
...
Unit 11- Assignment 5- D3
Acute lymphatic leukaemia
This type of leukaemia affects the lymphoid cells (lymphocytes), which form lymphoid or lymphatic
tissue
...
This cancer starts from the lymphocytes in
the bone marrow
...
After, they
can spread to the other parts of the body
