THE HEART

3

Introduction:The Heart is an amazing pump that works nonstop, keeping the body alive. With every beat, it sends a surge of bright red blood, carrying vital supplies, such as oxygen, and bodys waste products, such as carbon dioxide, through a network of blood vessels to and from every part of the body .

CirculationYour body resembles a large roadmap, There are routes or arteries that take you downtown to the heart of the city.

3 Major Parts of the Circulatory systemBlood Vessels - routes blood travels

Heart pumps or pushes blood through body

Blood carries important oxygen, food, & waste product through body

Functions of Arteries & VeinsARTERIES: The arteries take Pure Blood around the body from heart. They are Red in colour .

Veins: Veins return the Impure Blood to heart from body. They are Blue in colour .

Contains:There 4 chambers of heart. 2 upper chambers : Left Atrium Right Atrium

2 lower chambers : Left Ventricle Right Ventricle

Blood Flow through the Human Body

Blood with little oxygen is pumped from the Right Atrium through a valve to the Right Ventricle and through another valve into the Pulmonary Vein. The Pulmonary Vein sends it to the Lungs to pick up Oxygen. Its sent from the Lungs through Pulmonary Arteries to the Left Atrium through a valve to the Left Ventricle. The Left Ventricle sends it through a valve to the Aorta. The Aorta is a series of branches that sends oxygenated blood throughout the body.

Exterior Diagram Of Heart

Nonstop PumpThe heart is a muscular pump that works constantly to squeeze blood into blood vessels called arteries. The arteries take blood around the body, and the veins return the blood to heart.

The right pumpThe heart is really pumps side by side. The right pump sends blood along the pulmonary arteries to the lungs, where it absorbs oxygen. This blood then come back along the pulmonary veins to the left side of heart to pumped around the rest of the body.

The left pump The left side of the heart is larger and more powerful than the right side. While the right side of the heart pumps blood to the lungs, the left side pumps blood all around the body, delivering oxygen, energy, and nutrients from food to every part.

Then the blood, which is now low in oxygen, returns from all of these body parts along the veins to the hearts right side. There it begins its non stop journey back to the lungs and then around the body once again.

Lub

If you listen to your heartbeat, it makes a lub dub sound.The lub is when blood is pushed out of the heart into the body and the dub is the reloading of the heart with more blood ready to push it out to the bodyDub

The mechanical pump of a fountain uses force to squirt water a great distance.

Just as a fountain forces water out, just heart muscle contacts to push blood at great force into the arteries.Your heart will do this about two-and-a-halfBillion times during your life.

Powerful Pump

Heart Rate can be determined using a Stethoscope

Heart FactsDuring a typical day, the adult heart pumps out about 2,000 gallons of blood. That would be enough blood to fill more than 50 bath tubs.

In a typical adult at rest, the heart pumps 70 times each minute and sends out about 1/3 cup of blood with each beat.

The heart pumps about 5 liters (approx.) , of blood each minute , which is total volume of blood in an adult body . When heart pumps faster, it sends out 4times this amount.

Heart FactsHold out your hand and make a fist. If you're a kid, your heart is about the same size as your fist, and if you're an adult, it's about the same size as two fists.

Your heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times.

With each pump, blood surges out into the main arteries at a speed of 16 inches per seconds. If it were to pass through a hole the size of a pinhead at this speed and pressure, it would spurt more than 10 feet
