“No knowledge can be more satisfactory to a man or woman than that of their own frame, its parts, their functions and actions.” — Thomas Jefferson (1743 – 1826) (Modern interpretation of an original quote.)
The human anatomy is made up of ten biological systems. Each involves various organs that perform specific tasks. Our goal for better health is to create an environment in which all systems and their respective organs are functioning optimally.
For a basic comprehension of these body operations, below is a fundamental overview of our anatomy and its multi-faceted systems. In no way is this an exhaustive detail of physiology, but instead a quick and simple guide for understanding how our bodies work and why nutrients available through natural sources are important for us.
Our skeletal system is made up of bones, joints, ligaments and tendons. Their function is to protect our organs, shape and support our bodies; plus enable the body to move by operating in conjunction with the muscular system. The soft fatty tissue known as marrow inside our bones is responsible for producing red blood cells, white blood cells, platelets and other immune system cells. More detail about immune system cells can be found in the Lymphatic System / Immune System segment.
The reproductive system includes internal and external organs for both sexes. In men consisting of the testes, penis and prostate, and in women consisting of ovaries, the uterus and breasts. In males the testes generate male hormones responsible for secondary sexual characteristics such as puberty, growth of facial, pubic and armpit hair, muscle mass and bone density; plus produce sperm for sexual reproduction. The prostate aids in production of semen, and assists in releasing sperm during orgasm. In females the ovaries generate three forms of the female hormone estrogen which are responsible for secondary sexual characteristics such as development of breasts, growth of pubic and armpit hair, and also modulate the menstrual cycle and reproductive system; plus produce eggs for sexual reproduction. This system of male and female sex organs is responsible for the inception of new human life. Once a viable sperm permeates a fertile ovarian egg, this egg ultimately resides in the uterus of the woman and a fetus will develop over the course of nine months.
Organs of the human immune include lymph nodes and vessels, white blood cells, tonsils and adenoids, the thymus, spleen, appendix, Peyer’s patches and even our skin. This powerhouse of immunity may also be referred to as the lymphatic system. Its role is to help protect us against pathogens and disease. Our immune system initiates this defense process with the production of white blood cells, which in turn sends about one quarter of them (known as lymphocytes) to the lymph nodes to generate antibodies for further disease resistance. It also includes an arrangement of vessels and nodes for filtering out potential illness causing organisms. This network of vessels serves an additional purpose of dispersing fluids and nutrients throughout the body, plus provides for drainage of excess fluids and protein to prevent tissue swelling. Overall there are twelve different immune cells, all originate in the bone marrow, and each has a specific biological sentry function.
The respiratory system consists of the lungs, nose, mouth and trachea. Air enters through the nose or mouth and moves down a long tube called the windpipe or trachea, which divides into two bronchial tubes leading into the lungs. With every breath we take this system is responsible for transporting air into and out of the lungs, enabling our bodies to absorb oxygen at the cellular level. This is accomplished when oxygen passes through the millions of tiny air sacs in the lungs and enters our blood stream by way of the surrounding capillaries. During this process, the waste product of carbon dioxide is exhaled from the lungs.
Other body systems to be added… Thank you for your patience.
