(Reuters) - Pilots at Lufthansa (LHAG.DE) will hold a three-day strike next week in a row over retirement conditions, their union said on Friday, bringing more disruption to travelers after a spate of industrial action at German airports.
The pilots' strike, which will run from 2200 GMT on April 1 until 2159 GMT on April 4, is likely to cause the cancellation of hundreds of flights, and will be the third strike to hit Frankfurt airport, Europe's third-largest hub and Lufthansa's home base, in six weeks.
Lufthansa, Germany's largest airline, said it was considering its legal options but had not yet taken a decision on whether to launch action to prevent the strike.
It called on the pilots to return to the negotiating table and said that while it still hoped to reach an agreement, it was working to minimize the impact of the strike for its customers.
"We regret that during April 2-4 we will probably not be able to bring our customers home or to their destination as planned," the airline said in a statement.
The strike will also affect Lufthansa's cargo arm and its low-cost carrier Germanwings.
If it goes ahead as planned, the strike could be the largest faced by Lufthansa, a spokeswoman said. A four-day strike called by pilots in 2010 was halted after the first day. Analyst Juergen Pieper of Metzler estimated next week's three-da
The Human Heart
By Manaal Sheikh and Reese Furlong
Why do we have a heart? Without our heart, we wouldn't be alive! Our heart pumps blood to every part of our body. Our blood carries very important things that we need in order to survive (oxygen, nutrients, vitamins and minerals).
How does the heart look like?
Put your hand in a fist. That's probably the size of your heart! Now your heart is located behind the sternum (breast bone). Its protected by your ribs so it won't get damaged.
The walls of your heart are made of very strong muscles that squeeze and relax to pump blood all around the body.
Not this heart
How it looks like
How it works!
So you obviously know that it pumps blood to the body parts. But how does it work? The heart contracts in two phases. When the top part is relaxed, it fills with blood. Then the top contracts and the bottom relaxes. It's kinda like a pattern.
Here is some videos and more pictures!
Down below we have a venn diagram that shows a similar type of organ in a starfish's body. Go down for more information!
I open my eyes and direct light is shining right on my face. I put my hands over my face so I can cover my eyes. "What's happening?" I think to myself. Then suddenly the lights go out and the only thing I could see were five men in white masks that cover their noses' and mouths'. Then one man yelled "SHE'S AWAKE!" A ton of people surrounded me! I finally said, "What's going on?" No one spoke. Just the sound of drips of water clinging on metal. A young man with brown hair held a long tube filled with medicine. At the end of the tube was... A NEEDLE! My biggest fear was shots! The young man quickly put the needle in my arm and as my mother used to say, "Just breath", I calmly laid my head to the pillow and felt very drowsy. Everyone was blurry and I couldn't see anything clearly. Soon my eyes were shut and darkness filled the space.
I woke up from a sound from my alarm clock. My mother came to me and told me something that I couldn't possibly believe!! "I "DONT HAVE A HEART?!!"
She told me that I will get my heart back tomorrow as soon as they finish examining it. "So a day without a heart" I say to myself.
That afternoon I got terribly sick! I kept on coughing and sneezing and coughing again! Wait a minute I think to myself. "If I don't have a heart then no white blood cells would protect me from the bacteria!" I walk to my bed to sleep for a while. A couple hours later I woke up and I was GRUMPY as ever!! I got out of bed and stomped my feet across the blue carpet towards the door. I screamed "MOTHER COME RIGHT HERE RIGHT NOW. I NEED MY SMOOTHIE!!!" Just then my mother came in my room and started yelling at me. Then suddenly my brother came and told me that I was being a very grumpy person. He told me"I don't have a heart" as if he was joking. "Oh no"I say to my self. Well no wonder I was being crabby.
The next day when I got my heart back and I'm happy I'm back to normal! =)
Thank for Watching!
And don't forget to ask questions!
Your heart is located right there!
Your heart can keep beating even it is separated from the body because it has it's own electrical impulses!
Your heartbeat changes and mimics the music it listens to!
The blood takes about 20 seconds to circulate through your whole body.
By the end of a long life, a person's heart may have beaten about more than 3.5 billion times
Here is our song!
Thanks for Watching =)
