La dump, la dump, la dump! You hear that?  

What is that sound? Well hello everybody ,I am 

Guss , they often call blood, and since I travel 

all through out your body , I am going to be 

the one, who will explain to you just how you 

body work ,and that "la dump" sound you hear 

,it is just your heart pushing me around your 

body.

Lets take a journey and travel through your 

body .People often ask me, Blood, how do you 

move around the body. I always tell them I 

flow through your Circulatory system. Can you 

say that "Circulatory system. Here's how your 

circulatory system looks like.

The main parts of the circulatory system are 

blood vessels and the heart. Blood vessels are 

long tubes that help me travel through your 

body and gets me to the places that your 

bodies needs me. 

Your heart is a strong muscle, that never 

rests, its always working and been beating  

since the day you were created. Its actually 

not that big , and about the size of your 

fist.Your heart is a pump that pushes blood 

all through your body.

Its the hearts job to keep me , blood in motion 

around the body.Blood carries fuel,nutrients 

from our food ,oxygen, and also carries our 

bodies waste away. Yups that me!

Now lets talk about your heart cause it not hard to 

see it the most important part.Our heart powers 

the circulatory system.In our circulatory systems, 

our heart sends blood into two different direction 

every time it pumps. To pump me or blood into 

two ways at once ,the heart has two sides, and 

each side has two parts or chambers on top of the 

heart and bottom, for a total of four chambers. 

These four chamber work as a team.

Each side of the heart has a atrium and ventricle. The 

atria on both sides of the heart receive the incoming blood 

first , then sent to the ventricles to be sent out. A thick 

wall is in between that separates the two sides called the 

septum. 

The right side of the heart receive me, blood with 

very little oxygen and sends it to the lungs to get rid 

of carbon dioxide and pick up oxygen. Then the left 

side receive me with oxygen rich blood from the 

lungs and pumps it back to the body.
