Circulatory System Poster

The circulatory system transports essential oxygen and nutrients to every cell of the body. it also removes carbon dioxide and other wastes from the body. The circulatory systems consists of the heart, the blood vessels, and the blood. The blood is made up of red cells, white cells, platelets, and plasma. The blood vessels include arteries, veins, and capillaries. The human body contains more than 60,000 miles of blood vessels.
Small artereis, called arterioles, play an important part in the distribution of blood. Blood flows through the into capillaries, which form branched networks throughout the body. As blood cells flow through the capillaries, they give up oxygen and nutrients to the surrounding tissue spaces and take up carbon dioxide and other by-products of matabolism. Deoxygenated blood is then returned to the heart through the veins.

Heart Parts - Inside the Human Heart ...

The human heart is an amazing muscle that can circulate nearly one and a half gallons of blood throughout the body every minute. Simple in its structure, the heart is comprised of four chambers that work together to constantly pump blood to and from the body's trillions of cells. A series of four valves control the flow of blood between the chambers. These one-way valves are controlled by thin, string-like fibers called cho ..., which attach to the inner walls of the heart. The walls of the heart are made of a thick muscle tissue known as myocardium.
Collectively, the heart's parts work together as one robust unit, capable of beating billions of time while pumping millions of gallons of blood during a person's life.

Feeding the Heart - The heart has its own circulatory system - a series of coronary arteries and veins that circulate blood to and from the cells of the heart. Coronary arteries originate at the base of the aorta while the veins empty primarily into the right atrium.

The Heart's Parts:
Chambers: Atriac, Right Atrium, Left Atrium
Ventricles: Right Ventricle, Left Ventricle
Valves: Tricupid Valve, Pulmonary Valve, Mitral Valve, Aoritc Valve
Major Artieries & Veins: Aorta, Superior Vena Cava, Inferior Vena Cava, Pulmonary Trunk

Heart Facts - The Amazing Heart -

Have you given your heart a second thought today? It is easy to take this incredible muscle for granted. Although the heart is relatively small, it is responsible for powering the entire circulatory system. The heart must pump blood through miles of vessels, some of which are narrower than blood cells themselves! Most people's hearts weigh less than a pound, yet during an average lifetime will pump over 50 millions gallons of blood. In fact, in the time it takes you to read this (about a minute) your heart has circulated your entire supply of blood throughout your body.
The ancient Greeks called the heart “kandia” which is where we get the words such as “cardiac” and “myocardium.” Throughout history, the heart has been given special importance. The ancient Chinese and Egyptians believed it was the source of emotions such as happiness. Even today, these beliefs are still with us when we describe being sad as “broken-hearted.”

The Pumping Pipeline - Much like the hub of a computer network, the heart controls traffic through the entire ciruclatory network. End-to-end, this vast network of veins, arteries, and capillaries would span 60,000 to 70,000 feet, or about 14 miles! If spread out, the surface area of the cirulatory system is larger than a football field.
Pump Up the Volume - Every time your heart beats, it propels about two and ahalf ounces of blood inot the circulatory system. Not much, you say? Well, at this rate, your heart will pump more than 80 gallons of blood in an hour or about 2,000 gallons a day. In one year, a healthy heart may pump enough blood to fill 100 tanker trucks. It would take an oil tanker to carry the more than 50 million gallons of blood a single heart can pump in a person's lifetime.
In a Heartbeat - On average, an adult heart beats just over once per second, or about 70 times a minute. That's more than 100,000 beats a day. During your life, your heart may beat 2.75 billion times.
Make a Fist - You may be surprised to find that the human heart is actually rather small.
If you make a fist, you will see that it is about the size of the heart in the center of this poster - the average size of a human heart.
Ups & Downs of ECGs - Watch any medical drama on television and you'll surely see the video display of a heart beat known as a electrocardiogram or ECG.
By monitoring electrical discharges within the heart, doctors can identify an irregular heartbeat, or arrhythmia. An irregular heartbeat can signify a variety of other heart conditions. ECGs (sometimes called EKGs) can sometimes expose problems with the heart's circulatory system, conductive system or even problems with the heart's muscle tissue. Early detection of these condition may allow corrective actions to provide a normal, healthy life.

Heart Smarts - Guidelines for a Health Heart -

Although the human heart is very reliable, there are hundreds of factors that may contribute to inefficiency or failure of the this vital organ. In America, heart disease is the leading cause of death. Amazingly, heart-related diseases kill almost as many Americans as all other causes of death combined! Some factors leading to heart disease are genetic or otherwise uncontrollable. However, the ost common causes of heart disease – poor diet, inactivity, obesity, and smoking – are based on lifestyles and habits often established while we are young, Statistics show we can live longer, healthier, more active lives by adopting healthy habits at an early age.

Healthy Heart Habits:
Nutrition - When it comes to the heart, we truly are what we eat. By eating diets low in fat and cholesterol and high in fiber, we make the heart's work as easy as possible. Too much cholesterol in the blood can stick to the inner walls of blood vessels, making them rigid and decreasing the amount of blood that can flow through them. Foods that contain high amounts of cholesterol and fat contribute to high blood cholesterol levels in the body.
Eating low-fat, low-cholesterol foods and foods with high levels of soluble fiber helps lower blood cholesterol. Foods with soluble fiber include oat bran, oatmeal, beans, peas, brown rice, citrus fruits, strawberries and apples.
Exercise: Use it or lose it. Since the heart is a muscle, exercise helps it become stronger and more efficient. Even low-to-mederate intensity activities done for as little as 30 minutes a day, can have some benefits. Such activities include walking, climbing stairs, yard work, dancing or home exercise. More vigorous aerobic activities, such as brisk walking, running swimming, bicycling and inline skating - done three or four times a week for 30-60 minutes - can improve fitness of the heart and lungs.

Heart Habits to Break:
Smoking - If you do only one thing to protect your heart, give up smoking or never start. Smoking increases your risk for a heart attack by more than 400%. Smoking increases the likelihood of developing heart disease, hypertension, chronic bronchitis, sexual impotence, and cancer. Nearly one third of cancer deaths and 90% of lung cancer deaths are linked to smoking. The blood of a smoker is thicker, and the nicotine in the tobacco smoke increase blood pressure. Smoking also decreased the oxygen your lungs can provide to the blood.
Couch Potatoism - A quarter of all adults in America are not active at all, and half of the nations' young people don't get enough physical exercise to promote long-term health. Statistics are getting worse. Today, sedentary pastimes such as video games, surfing the Net and watching television are replacing the more physically demanding lifestyles of several decades ago. This is bad ... considering that couch potatoes are 50% more lively to develop hypertension and become obese. Hypertension and obesity are leading causes of heart disease.
Stress - is often blamed for hypertension, "the silent killers", which afflict more than 50 million Americans each year. Also called high blood pressure, this condition is more often due to controllable factors such as being overweight, smoking, and consuming too much sodium.
Although stress and tension can increase blood pressure to some extent, you can be more relaxed about your heart health by eating a healthy diet, exercising, and avoiding smoking at all costs.

Heart Cycles - Two Pumps In One -

The human heart functions as two separate pumps. The two chambers on the right handle only deoxygenated blood, while the two left chambers transport fresh, oxygentated blood.
The heart actually supports two distinct methods of circulation. The first is called Pulmonary Circulation, the other is Systemic Circulation. Keep in mind that these two circulations systems work simultaneously. Each time the heart beats, it sends blood out, both to the body and to the lungs. In order for the blood to complete circulation, it must pass through the heart two different times. One cycle sends it to the lungs, the other to the body.

Pulmonary Circulation is the process of pumping used, deoxygenated blood from the heart to the lungs where it exchanges its carbon dioxide waste for fresh oxygen and is returned to the heart.
The two chambers of the heart responsible for pulmonary circulation are the right venticle, which pumps deoxygenated blood to the lungs, and the left atrium, which collects fresh, oxygenated blood from the lungs.

Systemic Circulation is the process of moving oxygenated blood from the heart through the cirulatory system where it mourishes the cells of the body then returns, carrying its waste carbon dioxide, to the heart.
The chambers responsible for systemic cirulation include the left ventricle, which pumps fresh bolld to the body, and the right atrium, which collects the used blood from the body.
