Understand The Major Biological Hormones

Hormones are chemical messengers that flow through the human body, hormones control major bodily functions. These chemical messengers tell your body when you are hungry, they affect your emotions and your mood, and can even range to the complex systems of reproduction. Hormone are produced by glands, which are part of the endocrine system. In order to get a better feel and grip on what hormones are, you must understand the major hormonal systems.

There are many glands that produce hormones, but we are going to focus on the major ones. These major glands include the Hypothalamus, the Parathyroid, the Thymus, the Thyroid, the Adrenal, the Pineal, the Ovaries, the Testes, and the Pituitary.

These glands work together to create and
The Immune system is responsible for attacking organisms and foreign substances that invade your body, it's made up of cells, tissues and organs that work together. White blood cells called Leukocytes, come in two basic types which are Phagocytes and Lymphocytes, they combine to destroy disease causing organisms. Phagocytes are calls that basically chew up invading organisms, Lymphocytes are cells that allow the body to remember previous invaders to help destroy them if they ever enter the body again. There are B Lymphocytes and T Lymphocytes, the B Lymphocytes seek out their targets and defenders to basically lock and clamp them down, and the T Lymphocytes are sent to destroy the invaders that the B Lymphocytes tied
The male reproductive system includes the Testes and the Penis, the Testes is where sperm are produced, and the major internal organs of the female reproductive system include the Vagina and the Uterus, in which act as a receptor for the sperm. The Ovaries produce the female's ova l, and the Vagina is attached to the Uterus through the cervix, while the fallopian tubes connect to the Uterus to the Ovaries. Fertilization occurs if a sperm enters the fallopian tube and burrows into the egg, when the fetus produces I mature enough to survive outside I the womb the cervix dilates and contradictions of the Uterus propel it through the birth canal.

The Skeletal system consists of 206 bones, a network of tendons, ligaments, and cartilage that connect them together, initially when we are born we have 300 bones, some fuse together as the body develops. This system supports movement, protection, blood cell production, calcium storage, and endocrine regulation. The teeth in the human mouth are part I the skeletal system but are not considered as bones. There are two distinctive parts to the skeletal system, the Axial skeleton and the appendicular skeleton. The Axial skeleton has a total of 80 bones, it consists of the vertical
