Understanding the Body Systems

By Edited Nov 13, 2013 0 0

Body Systems Anatomy
Even if we see it as one unit, our body is actually composed of different organ systems that collaborate to give us one perfectly oiled machine we call the human body. A system, as many of us already know, is a collection of organs and structure sharing a common function. This doesn’t necessarily mean that these organs must be close or at proximity to each other, in fact some organs occupy diverse regions in the body.

Skeletal/Articular System

Anatomy Skeletal-Articular System

The skeletal system involves all the bones in the body, including the ligaments that anchor the bones at joints. The skeletal system provides structural stability of the body. We can walk, we can jump, we can do what we want with our body without having the fear of breaking down in the middle of it thanks to the sturdy bones we have. The articular system comprises the joints, both movable and fixed, including joint capsules, synovial membranes and discs.

Muscular System

Muscular System Anatomy

To simply put it, it entails the muscles in the body. From the muscles that form the face, the skeletal muscles that move the skeleton, the biceps and the triceps to the cardiac muscles of the heart walls and to the smooth muscle of the walls of the viscera and vessels and in the skin. As we continue to live, we unknowingly develop certain muscles to cater to our way of living so for those who wants to have hot abs, then do activities that single out the abs.

Cardiovascular System

There has been some confusion revolving this system, but for this article we will tackle it on a more specific manner. The four-chambered heart, the arteries carrying blood to the tissues, veins that return blood to the heart and the capillaries where gas and nutrients exchange is made possible, are all part of this system. In some scholarly article, the cardiovascular system includes the lymphatic system.

Lymphatic System

Lymphatic System Anatomy

Our body is roughly 60% water and the daunting task of tissue drainage simply can’t be done by the veins alone. This is where the lymphatic system steps in. It is a system of vessels that assist the veins in recovering the body’s tissue fluids. Located throughout the body, the lymph nodes filter the lymph and are part of this system.

Nervous System

Anatomy Nervous System

Considered by many as the primary organ system, the nervous system consists of the tissues that are impulse-generating/conducting that is organized centrally, the brain and the spinal cord, and spreads to the periphery. A wide array of actions is governed by this system and it is critical that the signals the nervous system emits are interpreted by the receiving body organ correctly. The involuntary fight or flight response is one of the actions that the nervous system regulates.


Endocrine System

Endocrine System Anatomy

Functions of multiple areas of the body are affected by chemical agents, known as hormones that are secreted by glands. These glands and hormones are part of the endocrine system. Although some of these hormones are governed by the brain, the hypothalamus to be exact, nothing can be taken away from the endocrine system as one of the most influential system in the body. Hormones help maintain balanced metabolic functions in many of the body’s systems.

Integumentary System

Anatomy Integumentary System

The skin is the largest sensory organ if the body and acts as the first line of defense against infection. It also protects the underlying tissues and organs from injury. The skin also helps maintain body temperature and helps synthesize vitamin D which converts to calcitriol, for normal metabolism. The skin is not the only part of this system, the sensory receptors, immune cells and antibodies are included in this system.


These are just overviews of the different systems and more will be discussed in another article. More can be learned by in depth reading and understanding of these systems to know the beauty and importance of their roles inside our body. Let your craving for medical knowledge lead you to seek more knowledge in order to value their significant task.
