So um, this is the heart, and I will try to model it. Thanks and peace

A little something...

I will be doing some more stuff on my book blog account, I will also talk to guys there, and it won't be just for books. Alsoooo, for the finale of my project I will be building a model heart, thanks and by

I have MORE!!!

Arteries

The arteries are major blood vessels connected to your heart.

• The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen.
• The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body.
• The coronary arteries are the other important arteries attached to the heart. They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function.

Veins

The veins also are major blood vessels connected to your heart.

• The pulmonary veins carry oxygen-rich blood from the lungs to the left side of the heart so it can be pumped to the body.
• The superior and inferior vena cavae are large veins that carry oxygen-poor blood from the body back to the heart.

Anatomy of the Heart

Arteries

The arteries are major blood vessels connected to your heart.

• The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen.
• The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body.
• The coronary arteries are the other important arteries attached to the heart. They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function.

Veins

The veins also are major blood vessels connected to your heart.

• The pulmonary veins carry oxygen-rich blood from the lungs to the left side of the heart so it can be pumped to the body.
• The superior and inferior vena cavae are large veins that carry oxygen-poor blood from the body back to the heart.

Details, details

Heart Chambers

The heart has four chambers or "rooms."

• The atria (AY-tree-uh) are the two upper chambers that collect blood as it flows into the heart.
• The ventricles (VEN-trih-kuhls) are the two lower chambers that pump blood out of the heart to the lungs or other parts of the body.

Heart Valves

Four valves control the flow of blood from the atria to the ventricles and from the ventricles into the two large arteries connected to the heart.

• The tricuspid (tri-CUSS-pid) valve is in the right side of the heart, between the right atrium and the right ventricle.
• The pulmonary (PULL-mun-ary) valve is in the right side of the heart, between the right ventricle and the entrance to the pulmonary artery. This artery carries blood from the heart to the lungs.
• The mitral (MI-trul) valve is in the left side of the heart, between the left atrium and the left ventricle.
• The aortic (ay-OR-tik) valve is in the left side of the heart, between the left ventricle and the entrance to the aorta. This artery carries blood from the heart to the body.

Valves are like doors that open and close. They open to allow blood to flow through to the next chamber or to one of the arteries. Then they shut to keep blood from flowing backward.

When the heart's valves open and close, they make a "lub-DUB" sound that a doctor can hear using a stethoscope.

• The first sound—the "lub"—is made by the mitral and tricuspid valves closing at the beginning of systole (SIS-toe-lee). Systole is when the ventricles contract, or squeeze, and pump blood out of the heart.
• The second sound—the "DUB"—is made by the aortic and pulmonary valves closing at the beginning of diastole (di-AS-toe-lee). Diastole is when the ventricles relax and fill with blood pumped into them by the atria.

To understand congenital heart defects, it's helpful to know how a healthy heart works. Your child's heart is a muscle about the size of his or her fist. The heart works like a pump and beats 100,000 times a day.

The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body.

The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart. Arteries are blood vessels that carry blood away from the heart to the body.

Ratings of hardness to pronounce levels:

**= Harder
***= WHY IS THIS SO HARD
****= WHY YOU NO EASY WORD!?!?!?!
*****= WHY YOU DO THIS TO ME GOD!?!?!?!? EVEN YOU CAN'T PRONOUNCE THIS WORD!!!!!!!
Today I will post another post on my book blog as well as this one. A few weeks ago, I sat there playing Fifa and winning 12-0 and wondering what to do for Genius Hour... and wondering what was for lunch. Anyway I thought I should have Pizza, about the blog, oh... I decided to do the human body, for now I will tell you guys about the human body.  So far  I have like, a zillion, or ten, words that are hard to pronounce. Any way the heart pumps 100000 times a day. It is also separated by a wall called the septum**.  The right side pumps blood into the lungs to pick up air/oxygen while   the left side takes oxygen rich blood and pumps into our beautiful and amazing body. That's all for now.... peace out!!!
