tarek,
Good luck, but I sure hope that my heart does not have 700+ species living in it

The formation of the puddlle was caused by lots of rain drops - that ceased to be when they created the puddlle. Also they flowed together to form it.
The puddlle is part of the entity of rainfall.
It's evaporated now so we can't touch it and it was wetter at the beginning than at the end.
It had a life ie; formed, existed then evaporated
It has been scientifically proven that approx 700 forms of life inhabit the average puddlle ranging from microbes and small insects to fish and hippopotami.
My beginning is the ending of others.

beginning of the large intestine as that honour goes to the ileocaecal valve with the
appendix being an add-on, an afterthought as it were at the end of the cul-de-sac of
the bowel, but never mind, I'm not bitter).
Loren G. Martin, professor of physiology at Oklahoma State University, replies:
"For years, the appendix was credited with very little physiological function.
We now know, however, that the appendix serves an important role in the fetus
and in young adults. Endocrine cells appear in the appendix of the human fetus
at around the 11th week of development. These endocrine cells of the fetal
appendix have been shown to produce various biogenic amines and peptide hormones,
compounds that assist with various biological control (homeostatic) mechanisms.
There had been little prior evidence of this or any other role of the appendix
in animal research, because the appendix does not exist in domestic mammals.
"Among adult humans, the appendix is now thought to be involved primarily in
immune functions. Lymphoid tissue begins to accumulate in the appendix shortly
after birth and reaches a peak between the second and third decades of life,
decreasing rapidly thereafter and practically disappearing after the age of 60.
During the early years of development, however, the appendix has been shown to
function as a lymphoid organ, assisting with the maturation of B lymphocytes
(one variety of white blood cell) and in the production of the class of antibodies
known as immunoglobulin A (IgA) antibodies. Researchers have also shown that
the appendix is involved in the production of molecules that help to direct
the movement of lymphocytes to various other locations in the body.
"In this context, the function of the appendix appears to be to expose white
blood cells to the wide variety of antigens, or foreign substances, present in
the gastrointestinal tract. Thus, the appendix probably helps to suppress
potentially destructive humoral (blood- and lymph-borne) antibody responses
while promoting local immunity. The appendix--like the tiny structures called
Peyer's patches in other areas of the gastrointestinal tract--takes up antigens
from the contents of the intestines and reacts to these contents. This local
immune system plays a vital role in the physiological immune response and in
the control of food, drug, microbial or viral antigens. The connection between
these local immune reactions and inflammatory bowel diseases, as well as autoimmune
reactions in which the individual's own tissues are attacked by the immune system,
is currently under investigation.
"In the past, the appendix was often routinely removed and discarded during other
abdominal surgeries to prevent any possibility of a later attack of appendicitis;
the appendix is now spared in case it is needed later for reconstructive surgery
if the urinary bladder is removed. In such surgery, a section of the intestine is
formed into a replacement bladder, and the appendix is used to re-create a
'sphincter muscle' so that the patient remains continent (able to retain urine).
In addition, the appendix has been successfully fashioned into a makeshift replacement
for a diseased ureter, allowing urine to flow from the kidneys to the bladder. As
a result, the appendix, once regarded as a nonfunctional tissue, is now regarded
as an important 'back-up' that can be used in a variety of reconstructive surgical
techniques. It is no longer routinely removed and discarded if it is healthy.
