Q

Describe the anatomy of human lymphatic vessels

A

Lymphatic capillaries the smallest vessels

  1. Blind-ended and start at capillary beds
  2. Endothelial cells overlap but are not continuous (fluid, solutes, pathogens enters but can’t return)

Q

List and give the location of the major human lymph and lymphoid organs

A

Primary Lymphatic organs are where B and T cells form and gain immunocompetence

  1. Bone Marrow
  2. Thymus
19
Q

List and give the location of the major human lymph and lymphoid organs

A

Secondary organs and tissues are sites where immune responses occur

  1. Lymph nodes and spleen have a capsule and are considered organs
  2. Lymphoid Nodules and MALT are tissues
20
Q

List and give the location of the major human lymph and lymphoid organs

A

Lymphatic organs contain a stroma of reticular connective tissue

21
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph nodes-principle lymphatic organs of body

22
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph nodes are small at up to one inch in diameter

23
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph nodes are numerous and approx 450 per person

24
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph nodes are bean shaped

25
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph nodes are embedded in connective tissues

26
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph nodes are concentrated in cervical, axillary, thoracic, abdominal, and inguinal regions

27
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph nodes are important diagnostically
1. Physicians palpate to check for infection
2. Biopsy if cancer is expected
Lymph nodes downstream of tumor may be affected due to metastasis

28
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph node functions:

  1. Only organs that filter Lymph
    a. help prevent further spread of pathogens by cardiovascular system
  2. Initiates immune response
29
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph node structure- capsule of dense connective tissue (collagen fibers) covers

30
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A 
Lymph node structure- extensions of capsule penetrate interior of node
      called trabeculae (fibrous partitions)
31
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph node structure- has stroma of reticular fibers that cells attach to

32
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymph node structure- there are more afferent lymphatics than efferent lymphatics

  1. slows down flow of lymph; it percolates through slowly
  2. encounters various immune cells such as macrophages, T Lymphocytes, and B Lymphocytes
33
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Node structure- 99% of pathogens are removed and lymphocytes are exposed to foreign antigens

34
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Lymphatic organs- Thymus and Spleen

35
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Thymus-

1. Located between sternum and aortic arch in mediastinum

36
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Thymus-

2. Does not function like a lymph node

37
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Thymus-

3. Site of development for T-Lymphocytes

38
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Thymus-

4. Release hormones called thymosins that regulate T lymphocytes development

39
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organs- Thymus-

5. Blood thymus barrier prevents premature exposure to its lymphocytes to antigens

40
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Spleen-

1. Located in Left hypochondriac region

41
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Spleen

2. Largest Lymphatic organ

42
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Spleen

3. Essentially a huge lymph node for the blood (not lymph)

43
Q

Describe the structure and function of human lymph nodes and lymphoid organs

A

Organ- Spleen

4. Destroys abnormal blood cells and platelets, and stores platelets and iron
