2) "Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart."

I woke up excitedly. This day was special. It was my birthday and I was sure that I was going to receive a great deal of wishes and presents this year. I got off from my bed and rushed to my bathroom to get dressed in the best possible manner. I wore the beautiful dress that I had bought especially for this day. I slipped on my twinkling jewellery, put on some light make-up, dressed my hair and went down for breakfast.
Mom was in the kitchen. I flashed a bright smile at her, waiting for her to wish me and give me a hug. But my smile soon vanished as my mother started rolling with laughter. I was confused. I asked her what was the matter? Controlling her laughter, she managed to answer me, which sounded something like, “Why are you dressed up like that early in the morning? Are you alright?”
I started wondering what was wrong with her, and my worries grew even more when she stopped laughing suddenly. With a concerned face she came towards me. She tapped my cheek twice and asked, “Honey, are you sleepwalking?”
