25
where are MALTs found
urinary digestive reproductive and respiratory tracts
26
what are aggregations
large clumps or clusters of lymphoid tissue
27
what are examples of aggregations
Peters patches, appendix, tonsils, bronchial nodules
28
what is the route through the lymph node
afferent vessels > subcapsular sinus > trabecular sinus > medullary sinus > efferent vessels
29
what are the two parts to lymphocytes
T cells and B cells
30
what are B cells
- originate in red bone marrow - matrue and become immunocompetent in red bone marrow - antibody mediated immunity
31
what are t cells
- originate in red bone marroq - mature and become immunocompetent in thymus - cell mediated immunity
32
what do B cells have?
plasma cells and memory B cells
33
what do plasma cells do
secrete antibodies
34
what do memory B cells do
aid in fighting foreign body at a future time
35
what do T cells have
helper T cells, killer T cells, and memory T cells
36
what do helper T cells do
secrete cytokines to help activate other immune cells
37
what do killer T cells do
directly attack and destroy infected cells
38
what do memory T cells do
aid in fighting foreign body at a future time
39
what are causes of tonsilitis
viral or bacterial
40
what are symptoms of tonsilitis
sore throat, fever, swollen lymph nodes, nasal congestion, difficulty swallowing, headache
41
what are treatments for tonsilitis
antibiotics or tonsilectomy
42
what causes appendicitis
blockage in the lining of appendix that results in infection
43
what are symptoms of appendicitis
abdominal pain, fever, nausea, vomiting, loss of apetite
44
what is metastasis in cancer
spread of cancer from one part of the body to another
45
how can metastasis occur
via blood vessels or lymphatic vessels
46
what are secondary tumor sites
establishment of new tumors where cancer cells are lodges after traveling though lymph or blood
47
what is the difference between cancerous lymph nodes and enlarged lymph nodes
cancerous lymph nodes are enlarged and firm and fixed, enlarged lymph nodes are softer tender and movable
48
what are treatments for elaphantiasis
preventative chemotherapy, hygiene, skincare
49
what is elephantiasis
lymphoma- tissue swelling
50
what are some functions of the endocrine system
secretes hormones to cause changes in the activity of target cells and direct cellular activities > maintains homeostasis
51
what are the components to the endocrine system
-pineal gland, hypothalamus, pituitary gland, thyroid gland, parathyroid gland, thymus, adrenal glands, pancreas, ovaries, testes
52
what are endocrine glands
secrete hormones into interstitial fluid and blood surrounding the secretory cells
53
what are exocrine glands
secrete products into ducts that carry secretions into body cavities into the lumen of an organ or to outer surface of body
54
what is paracrine
acting on neighboring cells
55
what is autocrine
acting on same cell that secreted molecules
56
which is faster endocrine system or nervous system
nervous system because fast acting travels short distances
57
what is the function of the hypothalamus
links nervous and endocrine systems | -regulates pituitary gland
58
what are some characteristics of the anterior pituitary gland
- composed of glandular epithelial tissue - makes and secretes 7 hormones - hypophyseal portal system
59
what is the hypophyseal portal system
hypothalamus will secrete hormones into blood that will stimulate or inhibit the secretion of anterior pituitary hormones
60
what are some characteristics of the posterior pituitary gland
- composed of neural tissue - stores and releases into blood 2 hormones - ADH and OT synthesized within cell bodies of hypothalamic neurons, packages into vesicles travel down axons into posterior pituitary and released into blood
61
what is negative feedback
- reverses a change in a controlled condition | - hormones released by target glands decrease secretions of their tropic hormones
62
what is positive feedback
- strengthens a change in body's controlled condition | - adds to or reinforces the initial change in controlled condition
63
what is type 1 diabetes?
autoimmune disorder > immune system destroys pancreatic beta cells and little to no insulin is produces
64
who does type 1 diabetes affect?
people under 20
65
what is type 2 diabetes?
decreases insulin sensitivity > pancreatic beta cells still produce insulin but insulin receptors on target cells become less sensitive to insulin
66
who does type 2 diabetes affect?
adult onset, largely affects people older than 35
