Body Systems
There are 10 body systems, one of them is the Integumentary (skin). It is
composed of hair, skin, nails, sence receptions and oil glands. Its functionis
to protect from outside, to regulate the body temperature, to make synthesis of
hormones & chemicals and is used as a sense organ.
Another one is the Skeletal System (bones). It is made of about 206 bones, that
are divided in tho categories: axial bones (in the body by itself) and
apendicular bones (arms & legs). We have Joints too. Thei`re divided in Ball
Socket (like elbow and shoulders) and sattle (fingers). This system`s function
are movement, storage of minerals, blood formation, support of the body and
protection of body parts. The next one is the Muscular System. It is composed of
muscles (dah). The muscles are divided in visceral or involuntary or smooth (The
one in the organs, like intestines), skeletal or voluntary or striated (found
superficial to the bones, like biceps, triceps...) and cardiac (heart). Their
functions are movement, to maintain body posture & tone and in the production of
body heat.
Now its time for the Nervous System. Its constructed of the brain, the spinal
cord and the nerves (neurons). Its functions are to communicate (fast with short
duration), integration, and to control. The subsequent system is the Endocrine
System (known as ductless too...). This is composed of a lot of things... They
are:pituitary gland - below the brain (master gland), pineal gland - brain (It`s
called the "third eye" by some, because its sensitive to light cycles),
hypothalamus - also in the brain (it works with the pituitary), the thyrodic -
neck (controls the metabolism), adrenal - kidneys (responsible for the
adrenaline), pancreas - near stomach (produces insulin), ovaries - on females
and testes - on males (it produces estrogen and ova - testosterone and sperm,
respectively). Their functions are to secrete hormones into the blood,
communication (slow & long duration), integration and control.
