Blood Air Barrier

We've learned that air comes down your trachea into your bronchi, then to bronchioles and finally to your alveoli where the oxygen you need goes into your blood.

The place in your alveoli where the oxygen in the air goes into your blood is called the blood-air barrier.

The air you breathe in has oxygen (sometimes called O2) that your body takes into your blood and sends all over your body.
Your body uses up the oxygen and sends back carbon dioxide (sometimes called CO2) in your blood to get rid of when you breathe out.

The blood-air barrier is where the oxygen goes in the blood, and the carbon dioxide comes out of the blood.
You can think of it like your body dumping out the old garbage CO2, and pickup up the new fresh O2 you need.

Waxing Crescent

We know that a full moon is when the sun is on the other side of us, shining right on the moon, and a new moon is when the moon is totally dark because it is in between the earth and the sun.


Right after a new moon, the moon will start to get some sunlight on it's right side. This makes a crescent shape, so we call it a crescent moon. Since the moon is going to get more full as the days go on, we use the word waxing to say that it is going to get fuller. So we can say the moon is waxing crescent.

Spanish - They are excited

We just learned that in Spanish I am happy is Estoy feliz, You are sad is Estás triste and He is angry is Él está enojado.

Now let's learn how to say They are excited.
We can break it up into the three words:
They - Ellos - sounds like ay-oh-ss /?/
are - estan - sounds like ay-stah-n /?/
excited - emocionados - sounds like ay-moh-see-oh-nah-doh-s /?/
