Muscles (Science Trek: Idaho Public Television) StudyJams. Muscle Facts for Kids. If bones give your body support, muscles give it power. You have over 600 muscles in your body. Some of these muscles control big movements, like the muscles in your arms and legs. Other muscles control very tiny movements, like blinking. Most of your muscles are attached to bones with tendons. Tendons are like strong rubber bands or ropes. Voluntary muscles are those that you choose to move. Voluntary muscles are those that you choose to move. All About Human Body Muscles: Working your muscles makes them stronger.

Skeletal Muscles | Skeletal Muscle Definition. You can see your muscles bulging and rippling under your skin when you move. These are known as the superficial muscles, and they are shown on the left of this image. Muscles are arranged in crisscrossing layers down to your bones. The deeper layers of muscle are shown on the right of this image.

This muscle raises your eyebrow when you look surprised. Facial muscles help you express yourself. This large muscle is called the pectoralis and it pulls your arm forward and rotates it inward. This triangular muscle is called the deltoid and it lifts your arm away from the body. Upper arm Upper arm Your biceps muscle pulls your forearm to bend your arm. Flexible fibers › Bands of muscle stretch across your abdomen, helping you bend, straighten up, or twist. Muscles are attached to bones by long, tough cords of tissue called tendons. The sartorius muscle is the longest muscle in your body, running from the outside of your hip to the inside of your knee.

Mouth Mouth Digestion begins in the mouth, where teeth cut and crush food into small pieces. In the mouth › Also called the gullet, this muscular tube transports food from the throat to the stomach. The liver is a large organ, which processes nutrients and produces bile, a green liquid that helps break down fat. Bile from the liver is stored in the gall bladder and released into the small intestine, where it turns fats into tiny droplets. Stomach Stomach The stomach stores and churns food. The stomach › The pancreas makes digestive enzymes and releases them into the small intestine. Small intestine Small intestine Most food is digested in the small intestine.

The intestines › Large intestine Large intestine Water from digested food is absorbed in the large intestine. Feces (poop) are stored in the final part of the large intestine, called the rectum, before leaving the body. The anus is the opening at the end of the digestive tract. Food groups › Balanced diet › How much exercise do you need? Science for Kids: The Digestive System. Our body needs food to provide it with energy, vitamins, and minerals. However, in order use food, we must first break it down into substances that the various organs and cells in our body can use.

This is the job of our digestive system. The digestive system acts in stages to digest our food. Each stage is important and prepares the food for the next stage. The entire length of our digestive system is around 20 to 30 feet! Here are the major stages of the digestive system: 1. 2. 3. 4. 5. The Liver and Pancreas The liver and pancreas do a lot to help the digestive system along.

The story we’re about to tell is of stormy seas, acid rains, and dry, desert-like conditions. It’s an arduous journey that traverses long distances and can take several days. It’s one in which nothing comes through unchanged. It’s the story of your digestive system whose purpose is turn the food you eat into something useful — for your body!

Down the Hatch It all starts with that first bite of pizza. Your teeth tear off that big piece of crust. Next, your muscles squeeze the wet mass of food down, down, down a tube, or esophagus, the way you would squeeze a tube of toothpaste. Inside your stomach Imagine being inside a big pink muscular bag — sloshing back and forth in a sea of half-digested mush and being mixed with digestive chemicals. Sound a little like an amusement ride gone crazy? Inside the small intestine, chemicals and liquids from places like your kidneys and pancreas break down and mix up the leftovers. But hold on! Factoids: An adult’s intestines are at least 25 feet. StudyJams. Facts About The Lungs | Breathing Facts. Your lungs and the airways that carry air in and out of your body are located in your head and chest. The airways include the nasal cavity, the throat, the voice box (larynx), and the branching passages inside your lungs.

Nose Nose Your nose warms and cleans air as it passes through the nasal cavity. To keep your airways clear, air is sometimes blasted out of your nose with a sneeze. Coughs and sneezes › Mouth Mouth Air can be breathed in and out of your mouth as well as your nose. Making sounds › Windpipe Windpipe Your windpipe (trachea) carries air to your lungs when you breathe in, and back up to your mouth and nose when you breathe out. Breathing › Lung Lung Your two spongelike lungs fill up most of the space in your chest.

Lungs › Your diaphragm is a sheet of muscle that sits under your lungs. Your heart pumps blood to your lungs, where it picks up oxygen. Your airways branch out into your lungs, getting smaller and smaller the deeper they go. Air and oxygen › Air and oxygen › Science for Kids: Breathing and the Respiratory System. Humans breathe through something called the respiratory system. This system is made up primarily of our lungs and windpipe. Why do we have to breathe? Our body is a very complex system. One of the main things it needs is energy. When we eat our body digests the food to get complex molecules like glucose, which it can use for energy. However, food alone isn't enough.

Breathing In We breathe in using a muscle called the diaphragm. Alveoli No, these aren't a kind of pasta! Breathing Out The alveoli don't just pass oxygen to our blood, they also help to clean out waste gas from our blood cells. Diagram of the Respiratory System Our Nose The nose does more for breathing than just providing a place for air to enter our body. Why do we get out of breath? When we run or do strenuous activity, our muscles burn energy and use up the oxygen in our red blood cells. Talking The respiratory system also helps with talking.

From the moment you are born, you breathe – in and out – all day and all night long. When you inhale, your lungs draw in oxygen, a gas in the air that we need to live. The oxygen is then sent through the blood to all parts of your body, where it gives energy to your cells. As the cells use oxygen, they make carbon dioxide, a waste gas. You breathe this gas out when you exhale. All About Human Breathing System: Main Parts of your Respiratory System Your lungs breathe in about 2,000 gallons of air every day – enough for the 2,400 gallons of blood that go through your heart every day.

At night, you inhale and exhale enough air to fill your bedroom! Your brain controls how fast your lungs draw in air. Your lungs breathe in about 2,000 gallons of air every day Human Breathing System Vocabulary Inhale: draw breath inExhale: push stale breath outOxygen: a gas in the air that has no smell or colorControl: driveDiaphragm: muscle that helps the lungs Learn More All About Human Breathing System.

StudyJams. Your Respiratory System | Discovery Kids. The respiratory system is the group of tissues and organs in your body that allow you to breathe. This system includes your airways, your lungs, and the blood vessels and muscles attached to them that work together so you can breathe. The respiratory system’s main function is to supply oxygen to all the parts of your body. It does this through breathing: inhaling oxygen-rich air and exhaling air filled with carbon dioxide, which is a waste gas. This is how the respiratory system works: first you breathe air in through your nose and mouth, which wet and warm the air so it won’t irritate your lungs.

Then the air travels through your voice box, down your windpipe, and though two bronchii (bronchial tubes) into your lungs. Cilia, tiny mucous-covered hairs, in your airways trap foreign particles and germs to filter the air that you breathe. You then cough or sneeze the particles out of your body. Fun Fact: You breathe in and out anywhere from 15 to 25 times per minute! Heart Facts For Kids | Blood Facts For Kids. There are three main types of vessels in your circulatory system. Arteries (red) take blood away from the heart, veins (blue) carry it back to the heart, and tiny capillaries (too small to be seen here) link the arteries and veins. Each artery has a name, which changes when it branches into smaller arteries. Similarly, the names of small veins change when they join wider main veins. The jugular vein drains blood from your brain. The superior vena cava is the main vein bringing blood from your head, neck, upper chest, and arms back to your heart. Aorta Aorta About the size of your thumb, the aorta is the biggest blood vessel in your body.

Blood vessels › Heart Heart The heart is a muscular pump, supplying blood to your lungs and body. Heart › Inferior vena cava Inferior vena cava The biggest vein in your body, the inferior vena cava, returns used blood from the lower part of your body to the heart. The iliac artery branches from the aorta and runs through your legs. Pulse › Heartbeat › Blood › Blood › Digestive System Facts for Kids. What happens when you eat your favorite food? Maybe it’s a slice of pizza or chicken nuggets. You know it tastes yummy, but what happens next? When your stomach is empty, you feel hungry. If you smell good food, your brain reminds you that you’re hungry. You take a bite, chew the food up and swallow it. Saliva, or spit, makes the food soft and gooey. All About Your Digestive System: A Complete Digestive Track Diagram Once you swallow your food, the process of digestion starts.

The food continues its journey through the small and large intestine. Saliva: spit or liquid in your mouthAcid: very strong liquids that break down foodNutrient: things your body needs to growCollect: gather The large intestine takes water and minerals out of the leftover food but that’s not all about your digestive system.

The circulatory system is centred on the HEART, a muscular organ that rhythmically pumps BLOOD around a complex network of BLOOD VESSELS extending to every part of the body. Blood carries the oxygen and nutrients needed to fuel the activities of the body’s tissues and organs, and it plays a vital role in removing the body’s waste products.

An average-sized adult carries about 5 litres (9 pints) of blood. All the output of blood from the left side of the heart goes into the aorta, the body’s largest artery. Other arteries branch from the aorta to supply blood to the head, limbs, and internal organs. The blood is drained from all these parts by veins into two large vessels, the inferior and superior venae cava, which deliver the blood back to the right side of the heart. The heart contracts tirelessly – more than 2.5 billion times over an average lifetime – to pump blood around the body. The heart has two upper chambers, called atria, and two lower chambers, called ventricles.
