Hi,
My
name is Franz Devantier, creator of this blog. I
am an Herbalist, who uses local and indigenous herbs when available, in
preference to imported herbs. Because
Herbalists deal with living human beings, it is important to have an
understanding of Anatomy and Physiology, as well as many other related
subjects,
such as How to grow old gracefully with Stem
Cell Enhancers.

Metabolism
Metabolism which means “a state of change”, is a term that
refers to all the chemical reactions that occur within body cells. Metabolism includes breaking down complex
substances into their simpler building blocks; synthesizing complex cellular
structures from simple substances, and also using nutrients and oxygen to
facilitate or cellular respiration, and in the process create ATP
molecules. ATP are molecules that store
energy to be released and power cellular activities.
Metabolism depends
on the digestive and respiratory systems to make to make nutrients and oxygen
available to the blood and the cardiovascular system. The cardiovascular system will distribute the
nutrients and oxygen to every living cell in the body that needs it.
Metabolism is regulated to a large extent by the hormones
secreted by the glands of the endocrine system.
So quite an interdependence.
Excretion
Excretion is the process of removing excreta, which are
waste products from the body. If the
body is to continue to operate efficiently, it needs to get rid of non-useful
substances that are produced during digestion and metabolism. There are several organ systems that
participate in the process of excretion, or elimination of wastes.
The digestive system rids the body of indigestible food
residues in the form of feces. The
Urinary system rids the body of nitrogen-containing metabolic wastes, in the
form of urea and uric acid, in the urine.
The lungs get rid of carbon-dioxide which is a by-product of cellular
respiration. The carbon-dioxide is
carried in the blood stream to the lungs, where it leaves the body in exhaled
air.
Reproduction
Reproduction can occur in two ways, firstly at the cellular
level, and secondly at the organismal level.
In cellular reproduction the original cell divides, producing two
identical daughter cells. Daughter cells
like these are used for body growth or repair.
Reproducing the whole human organism is the task of the reproduction
system.
Basically when a sperm unites with an egg, a fertilized egg
forms. This fertilized egg eventually
develops into a baby inside the mother’s body.
The reproductive system is directly responsible for producing offspring. The function of the reproductive system is
exquisitely regulated by the hormones of the endocrine system.
Because males produce sperm and females produce eggs or
ova, there are different functions in the male and female bodies with regard to
reproduction. The reproductive organs of
the males and the females are quite different from each other. The females reproductive structures provide
the site for fertilization of eggs by sperm.
These same structures then protect and nurture the developing fetus, until
birth takes place. After birth there are
still additional structures in the female that come into play.
Growth
Growth either refers to the increase in size of a body
part, or the increase in size of the entire organism. Usually growth is accomplished by increasing
the number of cells. Individual cells
also increase in size, while they are not dividing, so this cold also manifest
as growth.
For true growth to occur, anabolic or constructive
activities must occur at a faster rate than catabolic or destructive
activities.
