Below you will find a brief overview of each body system along with helpful educational links for adults and instructional links for teachers. Circulatory System The circulatory system consists of the heart and blood vessels which emcompasses all of the arteries, veins, and capillaries.
The arteries carry oxygenated blood away from the heart, and veins return deoxygenated blood back to the heart. The main purpose of the circulatory system is to transport blood, oxygen, nutrients and hormones to and from different cells and tissues throughout the body.
This system works hand-in-hand with the respiratory system to facilitate the exchange of oxygen and carbon dioxide within the blood per the alveoli in the lungs. It is also very important for the the removal of wastes and poisons within the body via the digestive and urinary systems.

All About the Heart for Kids: Watch a great video about the heart and the circulatory system. After the video, kids can read all about it as well.
Respiratory System The respiratory system primarily consists of the trachea, bronchi, bronchioles, alveoli, lungs and diaphragm. It's primary functions are to absorb oxygen through the inhalation inspiration of air and to expel carbon dioxide back out into the atmosphere through exhalation expiration.
This process is commonly called ventilation, otherwise known as breathing, which facilitates the exchange of oxygen and carbon dioxide between the lungs and atmosphere.
Within the lungs, oxygen and carbon dioxide are exchanged via the alveoli, which are tiny air sacs where this action takes place. During this process the newly oxygenated blood is pumped through the circulatory system by way of the heart to all of the cells, tissues, and organs throughout the body.
Includes an overview of the respiratory system, what happens when you breathe, what controls your breathing, and lung diseases and conditions.
Provides information on each section of the respiratory system and an overview of how it all works together. The lesson plan includes parts from part A to part D. The Respiratory System: Watch a video summary about the respiratory system. The video is for kids in the fifth grade. Kidz Search Encyclopedia: Respiratory System: Information about the respiratory system in an easy to understand format. Provides educational information on the respiratory system basics, including breathing, gas exchange, and cellular respiration.
Skeletal System The skeletal system is comprised of bones in total and consists of several different types of bones such as long, short, flat, irregular and sesamoid.
It also consists of all the joints, cartilage, tendons and ligaments within the body.
The primary functions of the skeletal system are locomotion, support of the body, and the protection of internal organs such as the brain, heart, and lungs. Bones are also responsible for the production of red blood cells, platelets and most white blood cells. Human Skeletal System: Learn about the skeletal system components, types of bones, and types of joints.
Systems: Skeletal System: Learn about the skeletal system inside and out by clicking on this link. While reading this page, people can also learn what the skeletal system does and how it works with other systems in the body. Learn the Skeletal System:Label the Bones: An interactive game for grades 4 and 5 that allows kids to label the various bones of the skeletal system.
Human Body: Human Skeleton Printout: Kids can ask their parents to print out this skeleton for coloring, or it can be colored online. Spaces are available for labeling the various parts. Skeleton Match Activity: Learning about the common and proper names of bones can be fun.
Print this PDF and connect the common names of the bones with the proper names. The Skeletal System: Read about the three major jobs that the skeletal system does. This link also tells how many bones there are in the human body. Muscular System The muscular system consists of skeletal, smooth visceral , and cardiac myocardium muscles. The primary functions of this system are movement, joint stabilization, heat generation, maintenance of posture, and the facilitation of blood circulation.
Skeletal muscles connect to bone and work hand-in-hand with the skeletal system to control voluntary movement such as walking and running.
Smooth muscles are involuntary muscles that are responsible for the contraction of hollow muscles which include the stomach, intestines, bladder and uterus. Cardiac muscle is involuntary muscle found only in the heart and facilitates the circulation of blood by pumping it to the major arteries and out into the body via the circulatory system. Muscular System: Facts, Functions and Diseases: Provides an educational overview of the human muscular system. Includes brief information about diseases of the muscular system.
Kids Health: Your Muscles: Easy to understand educational overview of the muscular system. Inner Body: Muscular System: Provides more in-depth information about the muscular system. Includes a 2D and 3D interactive anatomy explorer.
Muscle Activities for Kids: A collection of classroom and home-school activities and lesson plans that teach kids about their muscles. Assignment 2: Muscular System: This class assignment asks two questions about the muscular system, plus includes a bonus question. Links to explore for the answer are provided. The Digestive System The digestive system is mainly comprised of the gastrointestinal digestive tract which includes the mouth, esophagus, stomach, small intestine, and large intestine colon.
The liver, gallbladder, and pancreas are also a part of this system and are responsible for contributing to the chemical breakdown of ingested food. The main functions of the digestive system are digestion, absorption and the elimination of waste.
Digestion is the breakdown of foods by mechanical and enzymatic processes into substances that can be utilized by the body. Absorption occurs primarily in the small intestine and is the process by which vitamins, minerals, carbohydrates, fats, and proteins are passed on to the blood for energy.
Undigested and non-useful nutrients from food pass through to the large intestine and are eliminated as waste. The large intestine is also where the majority of water and sodium are absorbed into the body for use.
Kids Health: Digestive System: Click on this link for a neat video about the digestive system. Science Bob: The Digestive System: Learn about the nine basic steps that the human digestive system goes through.
Organs are moved into the correct location on the character's body. Digestive System Animation: A video that shows how the digestive system works for kids in grades 3 to Aerobic respiration The release of a relatively large amount of energy in cells by the breakdown of food substances in the presence of O2. Anaerobic respiration Anaerobic respiration: the release of a relatively small amount of energy by the breakdown of food substances in the absence of O2.
Anaerobic respiration in muscles during exercise: Anaerobic respiration in yeast: Muscles respire anaerobically when exercising vigorously, because the blood cannot supply enough oxygen to maintain aerobic respiration. Howerver, the formation and build-up of lactic acid in muscles causes cramp muscle fatigue. The lactic acid that is made is transported to the liver, and later is broken down by combining it with O2.
This extra O2 is breathed in after the exercise has stopped, and it is known as the oxygen debt. Structure of the breathing system: the larynx, trachea, bronchi, bronchioles, alveoli and associated capillaries.
Credit: biology-forums. Gaseous exchange relies on diffusion. These features are present in gills fish and alveoli lungs. The role of mucus and cilia - Inside the nose, thin turbinal bones are covered with a layer of cells. Some of which are goblet cells. Try this State how each feature labeled on the diagram of an alveolus makes the process of gaseous exchange efficient.
Moist surface- allow O2 to dissolve making diffusion faster. Red blood cells — contain haemoglobin to transport O2 away from the lungs. If not, alveoli walls would stick together, the lung would collapse. Try this a The composition of the air inside the lungs changes during breathing.
Describe three features of the alveoli which assist gaseous exchange. Its 4 main toxic chemicals: carbon monoxide, nicotine, smoke particles and tar. Tar and smoke particles do not — they stay in the lungs. Sample question The table shows the percentage of haemoglobin which is inactivated by CO present in the blood of taxi drivers in a city. Using information from the table, explain which source contributes most to this effect.
