What organ or lymph filters blood?

Nearly all organs in the body have a primary lymph node group filtering the tissue fluid, or lymph, that comes from that organ.

What are two diseases that your immune system can't fight?

I would like to believe that they can be Cancer and HIV/AIDS, since seeing that the body's immune system would be broken down/damaged and would not be able to defend the body (HIV/AIDS).I am not sure the reason for cancer

What is the name of the structural units of lymph node that contain a germinal center?

Is the central ,light staining region within a lymphoid follicle in spleen ,lymph nodes,or mucosal lymphoid tissue that forms during T cell-dependent humoral immune response and is the site of B cell and antibodies affinity maturation and antibodies class swiching .

Does stress weaken your immune system?

It definitely weakens your immune system! I contracted MRSA 4 years ago (due to surgery) and it took over a year after being off of IV antibiotics to build up my system enough that I would not have to go to the dr everytime I got a cold. I just could not fight anything off! Even now, I have a hard time kicking a minor cold.

Where does lymph go after it leaves the collecting ducts?

The processed lymph will exit one of the lymph ducts, the right lymph duct or the Thoracic duct, depending on where the lymph came from. When it exists the lymph duct, it will enter the subclavian vein, which is also near the superior vena cava, the final vein before blood enters the heart. The lymph once again a part of the bloodstream. It will once again serve its purpose as tissue fluid. hahaha

What group of proteins mark foreign invaders and attract phagocytes to destroy them?

B cells release antibodies that attach to foreign invaders and mark them for destruction by phagocytes.

What is a pineal?

The pineal gland (also called the pineal body, epiphysis cerebri, epiphysis, conarium or the "third eye") is a small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns and seasonal functions. Its shape resembles a tiny pine cone (hence its name), and it is located near the centre of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join.

Where is lymph located?

unlike blood, lymph does not have a pump to push it around the body therefore lypmh relies on the contraction of skeletal muscles and the bodys natural movement to push the lymph back upto the neck where it empties into the subclavian veins

Where does lymph fluid enter the blood stream?

Lymph enters the circulatory system at two places in the subclavian veins. One is on the left side and the other on the right side just under the collar bones on each side.

Is the integumentary the same thing as the immune system?

no it is not. The integumentary system is your skin, hair, nails, and sweat/oil glands. It works with the immune system in that it helps protect the body. The immune system helps fight off bacterial infections and viruses on the inside. they work together, but they are not the same thing.

How does continuous and prolonged stress affect the immune system?

Very simply stated: Stress causes an increase in the hormone cortisol. Cortisol is a glucocorticoid steroid and has a supressive effect on the immune system, as do all glucocorticoid steroids (ex. dexamethasone). They suppress the inflammatory process which is critical in a properly functioning immune system.

The ways in which the immune system is suppressed by glucocorticoids is EXTREMELY complex, but a simple way to put it is that it keeps white blood cells from doing their job and keeps them from communicating with other white blood cells.

What functions do organs in the lymphatic system have?

The adenoids, appendix, spleen and thymus are considered lymph organs because they contain hundreds of lymph nodes. These nodes contain thousands of monocytes and lymphocytes which are white blood cells that protect the body from and defend the body against pathogens.

Do spicy foods help immune system?

Yes, it will.

A balanced diet contains carbohydrate, protein, fat, vitamins, mineral salts and fibre. It must contain these things in the correct proportions.

Carbohydrates: a source of energy.Proteins: a source for growth and repair.
Fats
: a source of energy and contain vitamins too.
Vitamins
: A B C D E; essential for metabolic reactions.
Mineral Salts: required for healthy teeth, bones, muscles etc..
Fibre
: helps intestines function correctly.

Exercise is a best way to boost your immune system.

JUNK food; chips and coke sucks you!!! Avoid them.

Enjoy.



What virus attacks the cells in the immune system that produce antibodies-?

Not sure if it's a disease or virus (I'm tired), it's HIV and gives you AIDS. AIDS attack the T Cells that produce antibodies, which makes you vulnerable to sickness. You can get it from (no offense) gay s*x (for the children) and by injecting drugs into yourself I think. There may be another way, but I don't remember.

What is secondary lymphoid tissue?

Secondary lymphoid organs and tissues are the sites where lymphocytes are most active. The white pulp of the spleen is the common site for plasma cells to develop. Macrophages are also active in the spleen red pulp; where they engulf blood-borne antigens to be presented to T lymphocytes in the circulation.

Possible causes of blood and leukocytes in urine?

Yes there can be a correlation. Here's my story to compare with yours:

I am 55 yr old female with history of one calcium oxalate kidney stone attack at age 23 resulting in major emergency surgery due to blocked left kidney. My fever was 106.5 due to infection from blockage.

I remained symptom-free for 30 years, but 2 yrs ago, at age 53, I began to have "bouts" of left flank and back pain that could travel to groin that could be relieved by 2 Advils. Nothing like the pain I suffered from the stone blocking my kidney at 23, so I never knew that this odd & uncomfortable transient pain could be kidney stone gravel or sand, or just a small stone passing thru...

I assume I developed lactose intolerance & watched out, but still had bouts which also included belching. I also realized that the pain would appear 12 hours after eating certain foods, in particular, pineapple, oranges, pea soup. I next thought of diverticulitis due to the pain traveling and it seemed like trapped gas as the pain would totally disappear suddenly but without release of any gas. My insides seemed inflamed.

Three weeks ago I had another "attack" after gorging on chocolate & nuts, )both of of which are bad for oxalate stones) It began the usual 12 hours after eating the "bad" food. I had to take 3 Advil, but I slept and the pain was gone in the am but I did have some residual left flank tenderness for days afterward.

About 3 years ago, I got hooked on daily Pepsi and chocolate - both bad for calcium oxalate kidney stones. And I wasn't drinking any water daily! I did a symptom check online and kidney stones kept coming up so everything began to make sense -especially in light of my history at age 23.

I then bought some urine test strips online & my urine was positive for leukocytes (2+), Hemolyzed blood (small) & protein (one color above "trace") And my urine PH was only 5.0 which is highly acidic. (I never saw blood in my urine, nor did I have urgency or any bladder symptoms)

I have been testing now for 2 weeks. I began to drink 3 liters of water/day, added B6 50 mg, magnesium 500 mg, an alkalinity increaser citrite, & acidopholus/bifidus. I also began to take 800 mg/day of Andrographis (natural antibiotic) which has been used sucessfully to treat blood & leukocytes in urine after passage of kidney stones.

I am self-treating at this point. It's been 2 weeks and the protein is negative, blood is negative. PH is up to 7.0. But leukocytes took much longer to change. They are now down to 1+ from 2+ and I believe this is common in resolving infections and takes more time to become negative.

So, it's likely that kidney problems can be related to positive leukocytes in urine. In my case I am hoping that it's stones again, or stone sand/gravel that is/was causing my "bouts" over the past 2 years. However, many kidney diseases can also cause this. Do some research online and try the symptom checker. You also need to try to recall whether you had any flank pain in the week or so leading up to your positive test. You could also just have a UTI that resolved itself. It took me forever to find it, but I just read that a resolving kidney/urinary issue that is resolving can cause this positive reaction with no bacteria present

Good luck to both of us!

What is the purpose of the human leukocyte antigen test?

The human leukocyte antigen test, also known as HLA, is a test that detects antigens (genetic markers) on white blood cells. There are four types of human leukocyte antigens: HLA-A, HLA-B, HLA-C, and HLA-D.

What are the 5 lymphatic organs?

1) THYMUS: located just above your heart. It releases WBCs. WBCs travel to other areas in the cartiovascular system. the thymus is the gland that produces cells that are ready to fight infection.

2) SPLEEN: largest lymphatic organ. stores and produces lymphocytes. located in upper left side of your abdomin. It fills blood.

3) TONSILS: located at the back of the nasal cavity, on side of the throat, and back of tounge. WBCs in tonsils defend body against infection.

4) I have no clue and i am trying to find this out.
