Your Amazing Body!

Your body is like an incredible, busy machine! It works every second, even when you're sleeping, to keep you healthy and strong. Think about your heart beating 100,000 times a day!

Explore the body's amazing circulatory, skeletal, nervous, respiratory, and digestive systems.

Built from Tiny Parts

Your amazing body is built from tiny parts! It starts with microscopic cells, like your red blood cells. These cells group together to form tissues, then organs such as your heart, and finally powerful body systems like the circulatory system.

Human body systems: muscular, skeletal, nervous, and circulatory.

Meet Your Brain

Your brain is like the super-smart computer of your body. It helps you solve math problems, feel happy when you play with friends, and even remember your favorite video game. It also sends signals to your muscles so you can kick a soccer ball or write your name.

The brain: your body's super-smart computer, with intricate neural connections.

Human heart and blood vessels: a powerful, fist-sized muscle.

Your Powerful Heart

• A strong muscle, about the size of your fist.

• It never stops, pumping blood day and night.

• Sends oxygen and food to every body part.

• Pumps about 2,000 gallons of blood each day!

Breathing with Lungs

Your lungs are amazing, spongy organs inside your chest. They work like tiny air pumps, taking in oxygen when you inhale, just like filling a balloon. Then, they push out carbon dioxide, a waste gas, when you exhale.

Human lungs: Spongy organs for breathing and gas exchange.

A Mixing Machine

Powerful Helpers

The stomach is like a strong, stretchy bag made of muscles. These muscles squeeze and churn, mixing your food, much like a blender mixes a smoothie. This action helps break down a sandwich or a banana into smaller, softer pieces.

Inside your stomach, special liquids called digestive juices get to work. These juices contain strong acids and tiny helpers called enzymes. They dissolve your food, turning it into a thick, soupy liquid called chyme, ready for the next step in digestion.

Your Kidneys

Your Liver

Your kidneys are two bean-shaped organs, about the size of your fist. They work like a filter, cleaning your blood by taking out waste and extra water. This waste then leaves your body as urine, or pee.

Your liver is a large organ that acts like your body's cleaning crew and processing plant. It cleans harmful stuff out of your blood, like old medicines. It also helps turn the food you eat into energy and stores important vitamins for later.

Digestive system breaks down food for nutrients and energy.

What is Digestion?

• Breaks down food, like a tasty sandwich.

• Turns big pieces into tiny, usable parts.

• Gets energy for running, playing, and learning.

• Pulls out nutrients, like vitamins from fruit.
