English lesson

The human body consists of three main parts: the head, the trunk and the limbs. The limbs are divided into upper limbs, arms, and lower limbs, legs.

The head is composed of the skull, which contains the brain inside. At the front of the head, called the face , there are the eyes, the nose and the mouth. At the sides of the head there are the auricles, that is the outer part of the ears.

The lower limbs are also formed by three parts: the thigh, the leg and the foot. Feet, like hands, have five fingers.

The two upper limbs comprise three parts each: the arm, the forearm and the hand. This consists of the palm, the back and the five fingers.

The trunk is the central part of the body and is connected to the head through the neck. The trunk is made up of two parts: a superior one, called the thorax, and a lower one called the abdomen. The chest encloses the lungs and the heart, while the abdomen contains the stomach, intestine and organs for digestion and reproduction.

The Cardiovascular System

The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body's tissues. With each heartbeat, blood is sent throughout our bodies, carrying oxygen and nutrients to all of our cells.

The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation(the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.

Respiratory system

The job of your respiratory system is very simple: To bring oxygen into your body, and remove the carbon dioxide from your body. Your body needs oxygen to survive. Oxygen is used by your cells as it performs the functions of life. As your body uses oxygen, your cells produce another gas known as carbon dioxide. Too much carbon dioxide can be toxic, even deadly. For this reason, it is important that your body have a way to get rid of it.

The urinary system video-lesson

The urinary system makes sure you get rid of waste and the excess fluid

Parts of the Urinary Tract

You drink, you pee. But urine is more than just that drink you had a few hours ago. The body produces pee as a way to get rid of waste and extra water that it doesn't need. Before leaving your body, urine travels through the urinary tract.

The urinary tract is a pathway that includes the:

kidneys: two bean-shaped organs that filter waste from the blood and produce urine
ureters: two thin tubes that take pee from the kidney to the bladder
bladder: a sac that holds pee until it's time to go to the bathroom
urethra: the tube that carries urine from the bladder out of the body when you pee

The Skeletal system

[...] Just like a skyscraper, your body is built around a hard and strong framework. Instead of steel and concrete, your bones are made out of very hard materials that we will explore later.

In a building, workers use nails, bolts, glue and concrete to hold the building to the framework. Your body has similar materials, such as ligaments and muscles, which hold everything together.

The Muscular System

Our bodies are made up of a variety of very large and very small muscles. From the powerful leg muscles that you use when you jump up and down to the tiny muscles that make your eyes blink, anytime you move, you are using muscles. In fact, as you read this article on our website you are using muscles to move your eyes back and forth. Scientists have estimated that about 40%, or almost half, of your body is muscle.

Your digestive system...

started working even before you took the first bite of your pizza. And the digestive system will be busy at work on your chewed-up lunch for the next few hours — or sometimes days, depending upon what you've eaten. This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat. So let's find out what's happening to that pizza, orange, and milk.

Nervous System

As you read this article, hold your hand out in front of you. Now, wave hello at yourself. Okay, now tap yourself on the head. Alright, now lets try this same experiment again, only this time we will do it a little differently. Put your arm down. Now look at your other arm. Say out loud, “move arm.” Don’t move it, just tell it to move. Did it move? Why not? How does our arm know when you want it to move? Our experiment shows that your arm does not understand spoken commands. So what does it understand? What tells it to move? If you think it is your brain, you are correct. But wait a moment. Your brain is clear up in your head, while your arm is clear down on your body. How does your brain talk to your arm? Somehow they must be connected. The connection between your brain and your arm, as well as every other part of your body, is known as your nervous system.

The cells (video-lesson)

The Cell

The cell is the basic unit of life. Some organisms are made up of a single cell, like bacteria, while others are made up of trillions of cells. Human beings are made up of cells, too.

Different Types of Cells

There are lots of different types of cells. Each type of cell is different and performs a different function. In the human body, we have nerve cells which can be as long as from our feet to our spinal cord. Nerve cells help to transport messages around the body. We also have billions of tiny little brain cells which help us think and muscle cells which help us move around. There are many more cells in our body that help us to function and stay alive.

Although there are lots of different kinds of cells, they are often divided into two main categories: prokaryotic and eukaryotic.

Prokaryotic Cells - The prokaryotic cell is a simple, small cell with no nucleus. Organisms made from prokaryotic cells are very small, such as bacteria. There are three main regions of the prokaryotic cell:

1) The outside protection or "envelope" of the cell. This is made up of the cell wall, membrane, and capsule.

2) The flagella, which are a whip-like appendages that can help the cell to move. Note: not all prokaryotic cells have flagella.

3) The inside of the cell called the cytoplasmic region. This region includes the nucleoid, cytoplasm, and ribosomes.

Healthy food

Always serve breakfast, even if it has to be "on the run." Some ideas for a quick, healthy breakfast include:
- Fruit
- Milk
- Bagel
- Cheese toast
- Cereal
- Peanut butter sandwich
Take advantage of big appetites after school by serving healthy snacks, such as:
- Fruit
- Vegetables and dip
- Yogurt
- Turkey or chicken sandwich
- Cheese and crackers
- Milk and cereal
Set good examples for eating habits.
Allow children to help with meal planning and preparation.
Serve meals at the table, instead of in front of the television, to avoid distractions.
