-
What happens to the lymph nodes if you might be sick (infection)?
The nodes might swell.
-
What do the lymph nodes do?

The armpit
-
What are the lymphatic organs?

-
What are lymph nodes rich in?

-
Where do lymph nodes originate at?
in blood
-
What do lymph nodes do in the intestine?
Absorb lipids in the intestine.
-
What are the 3 functions of the lymphatic system?
1. Tranportation of protein and fluid that leaked back to the bloodstream.
2. LV absorb lipids from intestines and bring them back to the bloodstream.
3. Lympho/monocytes protect the body by attack foreign cells and organisms (creates antibodies).
-
What is interstitial fluid?
Fluid around cells and tissues; usually from substances leaking from the blood capillaries.
-
What are the structures of interstitial fluid and lymph capillaries?
- B. capillaries
- L. capillaries
- L. vessel
- Interstitial fluid
- Tissue cells (lymphoid tissue)
-
Where does lymph filter out from?
B. capillaries and into the spaces between cells.
-
Fluid that surrounds body cells is called interstitial fluid, which passes continuously into thin-walled vessels called lymph capillaries that course through tissue spaces. True or false?
True

What structure is this?
Thymus gland
-
What does the thymus gland do?
- provides immunity in fetus' and in early years
- makes cells inmmunocompetent (strong) in early life
- early removal, prevents the body from making antibodies against antigens

What are adenoids?
Mass of lymphatic tissue in the nasopharynx.
-
What are antibodies?
Protein produced by B cells to destroy antigens.

-
Axillary nodes are___.
L. nodes in the armpit.
-
What are B cells (B lymphocyte)?
Lymphocyte that matures into a plasma cell to secrete antibodies.
-
What happens to interstitial fluid in the L. capillaries?
Becomes lymph.
-
What is lymph?
Thin, watery fluid within lymphatic vessels and collected from tissues throughout the body.

Carrier of lymph throughout the body.
-
Paraaortic nodes are ___.
lymph nodes near the aorta in the lumbar area of the body.
-
What is a plasma cell?
Lymphocyte that secretes antibodies; matures from B lymphocytes.
-
What do the lymphoid organs do?
Produce lymphocytes; nodes, spleen and thymus gland.
-
What are monoclonal antibodies?
Man-made antibody (compared to made in the body, like a vaccine) to attack antigens to destroy cells.
-
Where are the tonsils located?
Back of the oropharynx (back of the mouth, middle part of the throat).

-
What is rhinitis, anaphylaxis, and atopic dermatitis?
- Rhinitis (nose infection/inflammation aka nasal congestion)
- Anaphylaxis (severe allergic response and life-threatening, can cause the body to go into shock due to massive shift of fluids in body)
- Atopic dermatitis (Eczema; causes dry, itchy and inflammed skin)
-
What is urticaria?
