Human Organs – Body Organs Systems

Human Organs make up the six key body systems. These are the skeletal system, muscular system, nervous system, digestive system, respiratory system and circulatory system.  Lets explain how each of these play a role in sustaining and functioning of the human body.

Skeletal system provides structure to the body and protects internal organs. It is made of bones, skull and skeleton. The muscular system supports the body and allows it to move. Biceps and triceps are examples of muscles found in this system. The nervous system controls thought, sensation, movement and virtually all body functions. The key part in this is played by the brain.

Digestive system breaks down food and absorbs nutrients. It consists of the stomach, small and large intestines and other parts. The respiratory system takes oxygen and releases carbon dioxide through lungs. Finally the circulatory system with heart at its core transports oxygen, nutrients and other substances to cells and carries away waste.

The below diagram displays where each of these organ systems is located in the human body.

Human Body – Human Anatomy

Human Body Anatomy is one the key areas of study in medical science. Understanding human anatomy is essential not only for medical professionals but also for general public. The diagram below shows various key organs and parts of the human body and is a great learning resource for kids and adults alike.

Human anatomy can be studied on a macro and a micro level. The macro view is called gross anatomy while micro is referred to as histology. In gross anatomy, the human body is studied through systematic and regional methods. Systematic looks at the human body through the lenses of different systems (e.g. circulatory, nervous, etc) while regional studies individual regions (or parts) of the body. Systematic is a more scientific approach as one gets to learn how various organs in the system interact with one another. The anatomy diagram that you see below simply lists various organs such as brain, heart, kidneys, liver, intestines and is more in line with the regional approach.

Digestive System Diagram

Digestive System is one of the key body systems, responsible for processing nutrients in food and ensuring the body receives enough energy to sustain itself and grow. As shown in the below diagram, human digestive system consists of the following parts: mouth, throat, stomach, intestines, bladder, rectum, anus, liver, colon, and other organs. Now lets explain what each organ is responsible for in the system.

Mouth is responsible for food intake and initial digestion with chewing and saliva beginning the food breakdown. The food then travels through the throat (pharynx) to the esophagus, which is a muscular tube-like organ connected to the stomach. Esophagus has a special valve, which prevents food from going backwards.

Most of the digestion happens at the stomach. Stomach acid breaks down the food into a paste-like substance. This substance then moves into the small intestine, where part of the food is still being broken down while most of the nutrients get absorbed into the blood. Pancreas, liver and gallbladder all support the functioning of the small intestine. The remains of the processed food move into the large intestine (colon). This is where stool is formed and processed. From a liquid like state, the stool hardens as water is further absorbed. The waste is then moved into the rectum. The digestive system diagram below shows the various organs in the described system.

Smiley Faces

Smiley Faces (often referred to as a smiley or a happy face) are a visual representation of a smiling person widely used on the Internet to reflect one’s emotion using only two characters. Since its introduction in 1963, the yellow happy face has become a pop culture icon. In 1982, smileys have entered the Internet with Scott Fahlman using it to convey jokes and emotions with his peers. The most common representations are : ) and :- ) Interestingly, the smiley has first appeared in Robert Herrick’s poem To Fortune in 1648, where he included a sentence ‘Upon my ruines (smiling yet :).

Since their introduction the smileys have expanded to convey other emotions, hence the other name, emoticon. Now smileys represent not only happiness but also sadness and a whole array of other emotions. Some of these are captured in the image below. With introduction of social media, the use of smiley faces have exploded with many platforms and apps offering a variety of emoticon options. There are also Unicode smileys going back to Windows 95 that can be accessed with various hotkeys on a Windows platform. Many smartphones including iPhone have adopted the use of happy faces in their text apps.
