il ne feut pas se fier-aux apparences.
/ you musn't trust appearances /
broken bodies bleeding with orange and crammed
into the crystalline surfaces of the buns, their shells
torn. from outside, they tantalise the tastebuds with
rising columns of fragrance and steam, seeping into
my expectant eyes. yet
curled beneath the translucent surface they screech,
scorched and weak from the heat, wriggled packets
lying still under the handmade sheets
as stock attacks the walls - an impenetrable prison
in one-bite portions.
Now she juggles poetry creative time with objective scientific time, she begins to feel increasingly split between her love for the two. One day while in the midst of doing questions about HIV/AIDS and human immunity systems, Wan-Hsia and her roommates begin thinking about human existence and the value of life.
The acquired immune system
The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body. It can take several days for antibodies to develop. But after the first exposure, the immune system will recognize the invader and defend against it. The acquired immune system changes throughout your child's life. Immunizations train your child's immune system to make antibodies to protect him or her from harmful diseases.
The cells of both parts of the immune system are made in various organs of the body, including:
Adenoids. Two glands located at the back of the nasal passage.
Bone marrow. The soft, spongy tissue found in bone cavities.
Lymph nodes. Small organs shaped like beans, which are located throughout the body and connect via the lymphatic vessels.
Lymphatic vessels. A network of channels throughout the body that carries lymphocytes to the lymphoid organs and bloodstream.
Peyer's patches. Lymphoid tissue in the small intestine.
Spleen. A fist-sized organ located in the abdominal cavity.
Thymus. Two lobes that join in front of the trachea behind the breastbone.
Tonsils. Two oval masses in the back of the throat.
How do antibiotics help fight infections?
Antibiotics can be used to help your child's immune system fight infections by bacteria. However, antibiotics don't work for infections caused by viruses. Antibiotics were developed to kill or disable specific bacteria. That means that an antibiotic that works for a skin infection may not work to cure diarrhea caused by bacteria. Using antibiotics for viral infections or using the wrong antibiotic to treat a bacterial infection can help bacteria become resistant to the antibiotic so it won't work as well in the future. It is important that antibiotics are taken as prescribed and for the right amount of time. If antibiotics are stopped early, the bacteria may develop a resistance to the antibiotics and the infection may come back again.
