A number of complex processes and systems together form the human body.

Review: Introduction to the Human Body

Younger primary students may have little knowledge about internal bodily organs. They tend to think the contents of the body are what they have seen being put into or coming out of it, such as food and blood. Their experiences with everyday cuts, scratches and bruises seem to reinforce a view that blood is below the surface of the skin, filling the spaces inside the body like a bag of blood.

Older children are more likely to be able to list a large number of organs but may not fully understand the function or interconnected nature of these. For example, students at these levels may realise that the heart is a pump but not realise that the blood returns to the heart, or they may believe that the brain helps the body parts but not always realise that the body helps the brain.

To survive and reproduce, the human body relies on major internal body organs to perform certain vital functions. When two or more organs along with their associated structures work together they become component parts of a body system. The brain is the control centre of the nervous system and is located within the skull. Its functions include muscle control and coordination, sensory reception and integration, speech production, memory storage, and the elaboration of thought and emotion. The lungs are two sponge-like, cone-shaped structures that fill most of the chest cavity.

Their essential function is to provide oxygen from inhaled air to the bloodstream and to exhale carbon dioxide. The liver lies on the right side of the abdominal cavity beneath the diaphragm. Its main function is to process the contents of the blood to ensure composition remains the same. This process involves breaking down fats, producing urea, filtering harmful substances and maintaining a proper level of glucose in the blood.

The bladder is a muscular organ located in the pelvic cavity. It stretches to store urine and contracts to release urine. The kidneys are two bean-shaped organs located at the back of the abdominal cavity, one on each side of the spinal column. The heart is a hollow, muscular organ that pumps blood through the blood vessels by repeated, rhythmic contractions.

The stomach is a muscular, elastic, pear-shaped bag, lying crosswise in the abdominal cavity beneath the diaphragm. Its main purpose is digestion of food through production of gastric juices which break down, mix and churn the food into a thin liquid.

The intestines are located between the stomach and the anus and are divided into two major sections: the small intestine and the large intestine. The function of the small intestine is to absorb most ingested food. The large intestine is responsible for absorption of water and excretion of solid waste material. Explore the relationships between ideas about internal body organs in the Concept Development Maps Cell Functions. It is useful to explore what internal organs look like and where they are located in order to understand the specific function of each and how each contributes to keeping the body alive and well.

Teaching experiences should begin to encourage students to consider how organs work together, i. This idea leads to the more complex idea that body parts form connected systems that contribute to the functioning of the body as a whole. Encourage students to work in small groups to create a common drawing of what they know about the inside of the human body.

Consider providing each group with an outline of a human body or have students trace around a group member lying on a large sheet of paper. Ensure students consider the location, size and shape of body parts in their drawings.

Have students include labels naming each internal part and consider getting the groups to research information about each organ. Provide each student group with at least three strips of paper. Display the questions and add further questions to the list as they arise from these discussions and observations. As a class, complete a bundling activity sorting the questions.

Students should discuss what groupings to use. These questions can then inform planning of further investigations. Revisit these questions at the end of each session and respond where appropriate with new information. These changing body displays become an integral part of the ongoing investigation and demonstrate a dynamic, changing display. To assist students to construct richer personal meanings for ideas and concepts related to internal body organs encourage them to complete sentence stems.

Sentence stems are incomplete statements designed to provide a structure for insights and observations. When students are familiar with a variety of major internal organs, provide activities that encourage students to consider how one organ is similar to or contributes to the work of another organ. Other questions might include:. Identify diseases and conditions commonly associated with each major organ, such as heart attack, asthma, stomach ulcer, etc.

Discuss contributing factors to these, such as inherited conditions. Explore how medicine has developed effective treatments for many of these, for example transplants, mechanical hearts and medication.

The brain is an amazing three-pound organ that controls all functions of the body, interprets information from the outside world, and embodies the essence of the mind and soul. Intelligence, creativity, emotion, and memory are a few of the many things governed by the brain. Protected within the skull, the brain is composed of the cerebrum, cerebellum, and brainstem. The brain receives information through our five senses: sight, smell, touch, taste, and hearing - often many at one time.

You have probably heard this Billy Ray Cyrus song. Heartache, heartbreak Did you ever wonder why the heart is associated with love? The heart was once thought to be the center of all thought processes, as well as the site of all emotions. This notion may have stemmed from very early anatomical dissections that found many nerves can be traced to the region of the heart.

Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph. Read more. Every tissue within the body requires oxygen to function.

Nurses need to understand the skin and its functions to identify and manage skin problems. This article comes with a self-assessment enabling you to test your knowledge after reading it. Nurses observe the skin of their patients daily and it is important they understand the skin so they can recognise problems when they arise.
