The Heart And Introduction To

Circulatory System

The heart is located a little to the left of the middle of your chest, and is about the size of your fist.

Location

arteries veins capillaries

Carry blood away fron the heart.The aorta is the largest artery.

Carry blood back to the heart.(contain valves)The vena cava is the largest vein.

Exchange of water, oxygen, carbon dioxide and many other nutrients ,waste and chemicals substances between blood .

Types of blood vessels

Blood moves through many tubes called arteries and veins which together are called blood vessels.

Red blood cells White blood cells Platelets

Transport and carry oxygen to all the body.

Attack bacteria and help fight disease or infection.

Help the blood if you get cut.

Types of blood cells

Blood delivers oxygen to all the body cells to stay alive. We need healthy living cells. Without oxygen, these cells would die.If the oxygen rich blood doesn´t circulate as it should , we would die.

Importance of the heart

The heart is a muscular organ in the circulatory system that is responsible for pumping blood throughout the blood vessels to our body.

Function of the heart

The right side of your heart receives blood from the body and pumps it to the lungs.

The left side of your heart receives blood from the lungs and pumps it out to the body.

How does it work?

The blood transports the messages to the brain in the nervous system. it also transports oxygen to the body cells in  the digestive system. It transports the nutrients to the organs and cells.

How does it works with others systems

Coronary heart disease Coronary heart disease refers to the failure of the coronary

circulation to supply adequate circulation to cardiac muscle and surrounding tissue. Coronary heart disease is most commonly equated with coronary artery diseases although coronary heart disease can be due to other causes.

Cardiovascular disease Cardiovascular disease is any of a number of specific diseases

that affect the heart itself and the blood vessel system, especially the veins and arteries leading to and from the heart. The disease usually suffer from forms that affect the blood vessels while men usually suffer from forms that affect the heart muscle itself.

Heart failure Heart failure, is a condition that can result from any structural

or functional cardiac disorder that impairs the ability of the heart to fill with or pump a sufficient amount of blood throughout the body.

Heart diseases

Try to be active every day for at least 30 minutes; an hour would be even better for your heart.

Try to eat at least 5 servings of fruits and vegetables each day .

Avoid sugary soft drinks, fruits drinks.

Don´t smoke it can be damage the heart and the blood vessels.

Important Tips

A Look Inside the Circulatory System

We’re here to introduce the circulatory system. The circulatory system is made up of two major pieces. Without these pieces you couldn’t live because you need the heart to pump the blood around the body and you need your blood vessels to guide the blood to different places like the brain.

Your Introduction to the Circulatory System

There are two major pieces, the heart and the blood vessels. The heart pumps the blood and the blood goes through the blood vessels around the body. You need both to live.

What’s in the System and How Each Piece Works

Taking care of the circulatory system is very important. If you smoke your blood is thinner so you get less oxygen. If you get a shortage of oxygen you won’t live very long because your body needs a lot of oxygen. You will also need a monthly check-up at the doctor’s office.

How to Take Care of the Circulatory System ?

• The heart beats 70 times a minute in an adult and even faster in a child

• Extra blood goes to the skin and muscles when we’re hot or working hard

• The heart beats more than 2 .5 billion times without ever pausing to rest

• People once thought illnesses were caused by too much blood, so doctors used leeches to suck out the “extra” blood

Fun & Amazing Facts about the Circulatory System

• Over half of you blood is a liquid plasma, the rest is made cells, the plasma is mostly water.

• Anger and excitement make the heart beat faster than normal so does eating.

• Mammals and birds have hearts with 4 chambers, frog hearts have 3, and fish have only 2.

• People living in high places with thinner air have more red blood cells. Their red blood cells carry less oxygen.

• The right side of the heart pumps blood to the lungs to deliver oxygen.
