Learn about the 12 systems of the human body. The more you know, the more you grow, or at least make use of yourself better…

Anatomy: Bones & Muscles & Organs (oh my!)

From an anatomical perspective, twelve systems work together forming the magical beast that is your body. It’s a whirlwind of coordination, calculation and change for our conscious minds. Become savvy, and live in harmony with the millions of functions occurring at any given moment of your life. The more you know, the less you leave [...]

Anatomy: Lymphatic System

Nutrition-filled lymph drains from blood into the body tissues, into lymphatic tissues, then into the lymphatic system where it is filtered and returned to the bloodstream. It also plays a major role in the immune system, filtering out disease-causing organisms, producing specialized white blood cells and antibodies. Although joined to the cardiovascular system by a [...]

ANS: The Autonomic Nervous System

The autonomic nervous system is divided into two subsystems, the sympathetic and the parasympathetic, which work in tandem, either in a synergistic or an antagonistic way. Sympathetically Speaking (SNS): Fight or Flight The sympathetic system [SNS] is responsible for providing responses and energy needed to cope with stressful situations such as fear or extremes of [...]

Anatomy: Digestive System

Whenever we eat or drink, a chain reaction of intense proportions begins.  Teeth and muscles are mashing, pulpy juices are flowing, chemicals are firing and valves are opening and closing with the synchronicity of rocket science. The digestive system mechanically, chemically and bacterially converts substances to energy, nutrients and waste.  It is regulated by hormones [...]

Anatomy: Respiratory System

The respiratory system’s main function is gas exchange, mainly carbon dioxide to oxygen via osmosis. It also enables speech and sound, and has an extensive defense system against pathogens. Parts & Functions Involved in Respiring (Breath) The first five parts listed below make up the conducting zone, and the last four make up the respiratory [...]

Anatomy: Endocrine System

Working closely with the nervous and circulatory systems, the endocrine system is a regulatory system of ductless glands secreting chemical messengers (hormones) to coordinate many cellular activities. Each of the 30+ hormones conducts unique business in the body such as managing body temperature, sleep cycles, weight, puberty, other age-related changes, and how you handle stress. [...]

Anatomy: Nervous System

Made up of your brain, your spinal chord, and a 47 mile network of nerves that thread through your body, the nervous system is the communication center for coordinating actions and reactions. Using chemistry, electricity and bundles of sensory cells (neurons), messages are rapidly delivered to and from your central nervous system. When a nerve [...]

Anatomy: Reproductive System

The reproductive system perpetuates our species by fusing two cells from different genders introduced through sexual intercourse or artificial insemination. Both genders create, ripen, store and transfer their respective sex cells (called gametes). Gametes in both sexes are created in a process called meiosis. When gametes combine successfully, the merged sperm and ovum form a [...]

Anatomy: Cardiovascular System

The cardiovascular system delivers oxygen and nutrients to the whole body, defends against infections, transports hormones, and collects waste products that end up in the excretory system. Parts Involved Heart – the extremely consistent pumping organ Blood (plasma, red blood cells, white blood cells, platelets) Vascular system (arteries, veins, capillaries) Bone marrow – produces blood [...]

Anatomy: Integumentary System

Our largest organ & waterproof barrier, our skin contains a variety of nerve endings that detect light touch, sustained pressure, cold, heat & pain. When receptors are stimulated, they create a series of nerve impulses we feel when the brain processes them.  Except for our lips, our palms and the soles of our feet, hairs [...]

Anatomy: Muscular System

Muscles are responsible for every movement and all traveling that occurs within, all managed through coordination and pulling. There are about 700 muscles in the human body, about 600 of which are skeletal. Parts Involved in the Muscular System Skeletal muscles – muscles attached to skeleton that enable movement (come in pairs, usually contract voluntarily, [...]

Anatomy: Skeletal System

Bones have two purposes. Some, like your backbone, provide the structure which enables you to stand erect instead of lying like a puddle on the floor. Other bones protect the delicate, and sometimes soft insides of your body. Parts Involved in the Skeleton Bones – adult skeletons have 206; newborns have significantly more that fuse [...]

Anatomy: Excretory System

The excretory system regulates blood chemistry, filters excess fluid and stuff your body can’t use, and removes waste products from the body. Parts & Functions Involved in Excreting Kidneys filter the blood via millions of nephrons, send the chemical waste and excess water down the ureters to the bladder, where it waits to leave via [...]
