The Cardiovascular System ( Circultary System)
Interested in learning more about the circulatory or cardiovascular system?
The Cardiovascular System and the Circulatory System is by far the most important system within your body as it powers the other organs located within your body. The circulatory system starts at the heart, and pumps blood towards other organs. This is vital as this sends oxygen and important nutrients to power other organs, as other organs need energy in order to sustain itself- just like everything else that's alive. It is made up of the heart, blood, and blood vessels (capillaries, veins, and arteries). The heart, which also provides oxygen and essential nutrients to the organs and tissues, pumps blood throughout the body. In return, the organs release waste products like carbon dioxide into the circulation for elimination. The regular exchange of oxygen, nutrients, and waste materials provides the body with the energy and resources required for proper operation. Furthermore, by supplying white blood cells to fight infections and helping to regulate blood pressure, the circulatory system supports the immune system. On this page, we will be exploring the human circulatory system, and how it constantly functions 24/7 in its role of keeping you alive.
100,000
times is how much your heart beats on a daily basis. Incredible!
7-8%
Of a humans body weight is blood. The average human body is made up of 5 liters of blood!
2,000
gallons worth of blood is pumped from your heart on a daily basis.
The Heart of The Operation
The heart is the heart of the operation. Without the heart, nothing would be functional. None of your organs, and none of the cardiovascular system would function. Learn about this incredible organ, and how it keeps up 24 hours a day in order to keep you alive as the most vital organ of the human body.
The Cardiovascular System- the start at the heart.
The primary organ of your cardiovascular system, a web of blood vessels that circulates blood throughout your body, is your heart. It also interacts with other bodily systems to regulate your blood pressure and heart rate. How well your heart functions is influenced by your family history, personal health history, and lifestyle. The heart beats about 100,000 times per day, pumping 8 pints of blood around the clock. By doing this, waste is removed and tissues and organs receive blood that is rich in nutrients and oxygen. The lungs receive deoxygenated blood from the heart and fill it with oxygen while releasing carbon dioxide, a waste product of metabolism. This single organ is responsible for powering the rest of your body by sending them nutrients and oxygen- but how could this organ, the size of your fist, power your entire body? Join the Calvin Health Organization to explore the unique properties associated with this organ, and how it works to keep us alive.
Normally, the heart has two upper chambers and two lower chambers. Blood enters the right and left atria, the upper chambers. Blood is pumped from the heart by the stronger right and left ventricles, which are the lower chambers. The gates at the chamber openings are the heart valves, which maintain blood flow in the proper direction.
Major Vessels of the Body
These vessels help to transport blood around the body. The major blood vessels are arteries, veins, and capillaries.
Did you know?
Your body has more than 60,000 miles of blood vessels that circulate about 1.5 gallons of blood every day.
The Heart of the Operation- blood is pumped from your heart, into the arteries.
Blood is the foundation for most life. Blood is a vital part of your circulatory system which is pumped from the blood, and sent to other organs. Blood are responsible for the transportation of nutrients and oxygen to other organs, and to also transport the waste product of Co2. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Lets better understand what makes up blood.
Plasma
Plasma is the liquid part of blood. A yellowish liquid makes up 55% of the total volume of blood. Plasma is responsible for transporting the various substances associated with blood.
Red Blood Cells
Red blood cells are responsible for carrying oxygen from your lungs to the tissues and the organs in the body. Welcome to respiration 101!
White Blood Cells
The white blood cells are the warriors of your body- responsible for defending, and fighting off any foreign substances and any infections that may pose a risk to your body.
Platelets
Small, colorless blood cell fragments called platelets, also known as thrombocytes, help to stop or slow bleeding by forming clots. Our bone marrow, the sponge-like tissue found inside our bones, is where platelets are created. Stem cells that differentiate into platelets, white blood cells, and red blood cells are found in bone marrow.
Waste Products
Waste products, like carbon dioxide, are transported in the blood to the organ responsible for the elimination of the waste product. Mainly to the lungs.
What factors changes your heartrate?
AGE
The heart and blood vessels can alter as we age. For instance, as you age, your heart can no longer beat as quickly as it could when you were younger during physical exertion or stressful situations. However, normal aging does not significantly affect the heart rate (the average number of beats per minute) at rest.
ACTIVITY
Your heart usually beats more quickly during exercise to increase blood flow to your body. By pumping harder or increasing the volume of blood that fills the left ventricle before your heart pumps, you can also increase the volume of blood that passes through it during each stroke. When we're doing something like running, more oxygen is needed to fuel and power our organs,
LIFESTYLE
Your lifestyle plays a large role in the overall health of your heart, and the cardiovascular system. Your lifestyle, like whether or not you're a smoke, physical activity, and diet can play large parts in your cardiovascular system. According to research, smoking makes your heart work harder by raising heart rate, constricting major arteries, and possibly even creating an irregular heartbeat.
31%
Of all deaths anually are caused by heart disease, accounting for 17.9 million deaths globally.
47%
Of all Americans have high blood pressure, high LDL cholesterol, or smoking- making them at risk of heart disease.
92.1
Amercians have some form of cardiovascular disease, accounting for 27.8% of the pop.

What makes a heart attack so deadly?
Your organs constantly need to be fed oxygen, and nutrients in order for it to keep sustaining its process. The heart is the organ which is the heart of the entire operation- constantly fueling your organs of nutrients, and oxygen. Without blood, its only a matter of minutes before we are met with organ failiure.
Heart disease refers to a wide range of conditions that can negatively have a lasting impact on the heart, and the blood vessels, which in long terms will damage other organs. Coronary artery disease is the leading causes of heart diseases, caused by the build up of plagues in the arteries that supply blood to the heart. This plaque is made up of a variety of cholesterol, fat, calcium, and other substances in the blood that can harden, and prevent blood from reaching or flowing out of the heart. With this buildup, this can be life threatening if not enough blood is being pumped out. Your heart needs to work harder in order to pump enough blood. The main causes of heart disease are lack of physical activity, high consumption of trans fat, lifestyle choices, high blood pressure, and genetic.
