Have you ever noticed that tigers have striped on their skin but lion don’t have.

Many animals that belong to the cat family have stripes or some spots or patterns on their skins.

They also occur on tiger and leopard.

You can heard roar of the lion approx 8 km and also it can reach speeds of up 80 kph. But apart that lion don’t have stripes on their skin.

This is because these animals hunt in the jungle and mostly at night, and these strips prove beneficial in hunting them.

These spots are also more beneficial for hiding them.

Lion hunts mostly in open places, its fur is not so visible in grass. So it is easy to hunt.

Lions always live in the herd and for this reason they are not detected from a distance.

Why are bones important?

Every one of us has a skeleton made up of many bones. We have 206 bones in our body.

Each bone has a function. Some bones offer protection to softer, more fragile parts of the body.

For example, the skull protects the brain, and two bony sockets in front of the skull protect the eyes.

The ribcage protects our heart and lungs, while the spinal column protects the delicate spinal cord.

Other bones, like the bones in our legs and arms, help us to move around by providing support for our muscles.

Bones store calcium while the bone marrow produces red and white blood cells.

Remember, if your body does not get enough calcium, it will take it from your bones making your bones weaker. So, drink your milk to build strong bones!

BREATHING and its importance?

In this article we’ll discuss the process of breathing and why it is so important for us.

To understand the cycle and concept of breathing, we should look at the definition of breathing firstly.

Breathing supplies oxygen to the lungs and eliminates carbon dioxide

We breathe air to survive, which contains oxygen, which is necessary for life

Air is enter and exit from lungs through the nose.

Firstly air is taken in through the nostrils. This is the first step of breathing

Inhaled air takes moisture from mucus and warmed from underlying blood vessels , and filtered from nose hair.

After moistened, warmed and filtered air travels through the mouth and nasal passages.

It then passes through the trachea, and trachea is the connection between the throat and the lungs.

Trachea is divided into two bronchi, air is passes through one of them.

After passing into the many bronchioles, it finally arrives into some of the millions of tiny sacs called alveoli.

This is where gas exchange takes place – oxygen passes out of the air into the blood, and carbon dioxide passes out of the blood into the air in the alveoli.

Below the lungs, there is a flat powerful muscle called diaphragm.

The diaphragm contracts and relaxes, and as it does so, the volume of the chest increases and decreases to suck air into the lungs and then force it out.

Arrhythmia is a disorder of the heart that affects the heart rate . An arrhythmia represent an irregular heartbeat. With this condition, a person’s heart can beat ———-

• too fast (tachycardia)
• too slow (bradycardia)
• too early (premature contraction)
• too erratically (fibrillation

Arrhythmias occur when the electrical impulse that regulate heartbeats are not working properly.

An irregular heartbeat can feel as a racing heart or fluttering.
Brain, lungs and other vital organs can be affected by the Arrhythmias.
