human bodyThe human body functions like a complex machine working towards the completion of an important task. In order for the human body to get everything done perfectly, it has to rely on a system.

In fact, the body consists of several major organ systems that work in tandem to create a complex organism. These organ systems include the cardiovascular, digestive, integumentary, lymphatic, musculoskeletal, nervous, endocrine, respiratory, excretory, and reproductive systems.

Each of these systems has parts that make them function smoothly, even if they are not directly involved in the system.

In addition, several of the body’s systems are connected to major organs while others are not. Some of the organ systems take precedence over others, such as the cardiovascular system, making them very important role players in the overall organization of the human body.

However, the human body relies on each of these systems to live.

Without our bodies, we wouldn’t be able to talk, sit, stand, run, or play. Our sensory abilities would stunt our everyday enjoyment.

Imagine not being able to speak to your friends, taste your favorite food, listen to your favorite band, or dance or play sports. The nervous system make all of these exhilarating life experiences possible by processing signals from our nerves, through our spinal cord, and to the brain and back again.

The circulatory system transports nutrients and molecules to cells and tissues throughout the body.

The digestive system helps to distribute those nutrients by breaking down food molecules that will nourish and energize the body. Our respiratory system provides the body with oxygen molecules inhaled from the outside environment.

The human body also has active organ systems that help protect it from the outside world.

For instance, the integumentary system protects the body’s organs from damage, stores fat, and vitamins and produces hormones through the skin. The skin gives us our beauty and complexion while also eliminating toxins through our pores.

The musculoskeletal system gives the human body its’ shape and form while also providing movement in the environment. If we never had muscles or a skeleton, our bodies would simply fall into a huge pile of organic “goo.”

The endocrine system helps to provide growth and maintain homeostasis within the body.

It helps produce hormones that make our bodies grow and thrive. The lymphatic or immune system defends the human body from harmful “invaders,” such as toxins, free radicals, heavy metals, and pathogens. If our lymphatic system fails, then we can become victims to illness and disease.

Our excretory system allows the human body to rid of byproducts through the intestinal or urinary tracts. This is very important because our bodies cannot handle excess foreign “invaders.”

Lastly, our reproductive systems allow us to procreate. Both male and females have their own reproductive organs. When both come together, they create offspring that carry a mixture of their own genetics.

As you can see, these systems are vitally important for the continuation of the human body.
