The Cardiovascular system which is also known as The Circulatory system is the transporter of the human body. The Cardiovascular system pumps the blood which carries nutrition and oxygen to places that need them. For example, if you are running your legs and arms need oxygen so the heart pumps what the arms and the legs need. Bring the waste out of the human body is anther job of the Cardiovascular system. The waste that goes out are the waste from the body tissues which are filtered out from the blood as it flows through the kidneys. The waste then leaves the body in the form of urine. There are five or more organs in the Cardiovascular system, One of them is the Heart. The heart is the major organ of the human body, the hearts job is to pump the blood around the body so that the parts can get the nutrition and the oxygen they need. …show more content…
The Arteries are the blood vessels that carry the blood away from the heart. Returning to the blood to the heart is the Veins. The Capillaries are ones that exchange gases , nutrition and waste. Our cardiovascular system has parts there names are the : The pulmonary circulation, which is a short loop from the heart to the lungs and back again, and the systemic circulation. The system we usually think of as our Cardiovascular system because it sends blood from the heart to all the other parts of our bodies that is why people think that it is the Cardiovascular system. Without the Cardiovascular system you would not live because you need to get oxygen to parts of your body and nutrition if you don't get them then you muscles will get weak and you will be unable to move and your heart will stop beating. Last you die
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
The human body is an amazing machine, we have cells, tissues, organs and organ system that come together to create the human race. Each system plays a key role in our bodies mechanism. Without each systems our bodies would not function properly, but what happens when one of these system fails? The Cardiovascular system components are blood, blood vessels and the heart. The hearts function is to pump blood to all the major organs and tissues (Circulatory). It’s also important to be aware of the derivation that our bodies may encounter, for example a stroke. In this passage I discuss different types of strokes, what are the signs and symptoms and after care for this disorder of the cardiovascular system.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
The heart is one of the most unique organs in the human body. Its capabilities and functions truly are amazing. The heart 's function is to pump blood throughout the body supplying oxygen and nutrients to tissues. The heart is the size of your fist and weighs roughly 8-12 ounces depending if you’re male or female. The heart pumps through 100 kilometers of blood vessels for blood that is 3 to 4 times thicker than water at 60 to 80 times minute for a total volume of 5 million liters a year at rest. A basic diagram of the heart includes, right coronary, superior vena cava, aorta, pulmonary artery, pulmonary vein, right atrium, right ventricle, left atrium, left ventricle. There are more in
The cardiovascular system keeps blood circulating throughout our bodies constantly, and without it, many of the activities that we do would not be possible! The heart is the main organ of the cardiovascular system because it pumps the blood, and also a major organ of the human body because of how it is able to allow our bodies to work. Unfortunately, the heart may fail to function at times when blood flow is reduced as a result of blockage. This is more commonly known as a heart attack, or myocardial infarction. According to “Heart Disease Statistics,” approximately 715, 000 Americans suffer a heart attack every year . This deadly disorder of the heart can be diagnosed from symptoms, as well as from imaging and tests, and it is possible to
In the body, bodily systems work hand in hand with one another to perform key functions. The circulatory system is a major system of the body, it comprises of the heart and three types of blood vessels know as the capillaries, veins and arteries. The heart is a muscular pump which has the duty of pumping blood so it is carried to the blood vessels, until it reaches the chambers in the heart. These capillaries carry oxygenated blood via the bloodstream so that organ tissues recive oxygen. The capillaries will take in any excess amount of carbon dioxide; this is carried to veins so the blood can be transported back into the heart and then the lungs.
Have you ever felt a chest pain, sudden dizziness, weakness, fatigue, etc.? If you answered “Yes” to any of this, it can be Atherosclerosis. On this paper I’m going explain in detail what does Atherosclerosis means. What are the causes, symptoms, treatments? Can we melt the fatty plaques naturally? And more different information in relation to this subject. Atherosclerosis is not an illness that you get from one day to another, actually is an illness that by age, high pressure, the type of your diet, lack of exercise, even people with diabetes would have atherosclerosis with the time. But is not something that cannot be treated, you can go to the doctor for a checkup, change of diet, increase your physical exercise, etc.
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...
... Then the s The vascular system consists of blood vessels in the body. The vessels become smaller as they extend farther from the heart. The aorta delivers its flow to large arteries into smaller vessels. Arterioles supply tiny capillaries which nourish tissues.
One of the most important systems in the body, keeping it alive, is the cardiovascular system. As a part of the circulatory system, the cardiovascular system pumps blood throughout the body through a network of many arteries and veins, providing it with nutrients and oxygen. Also, the cardiovascular fights infections and disease in the body and creates blood cells. Never the less, blood acts as a filtration system for the body and removes waste, cell debris, or bacteria from the bloodstream.
Throughout Chapter 39, you are introduced into the major concepts of the circulatory system, the lymphatic system, the heart and how blood flows through it, and the respiratory system as well as the path of airflow through the respiratory system. In Section 1, you are introduced to arteries, capillaries, and veins as well as what consists of blood plasma. You are also introduced to the different blood cells and cell fragments such as red blood cells, white blood cells and platelets. In Section 2, you are introduced to both the pulmonary circulation loop as well as the systemic circulation loop. You are also introduced to how blood flows through the heart, as well as how contractions take place throughout the heart. Lastly, in this section you
The heart, blood and blood vessels make up the cardiovascular system. The function of the cardiovascular system is to evenly distribute blood cells, water and nutrients. The cardiovascular system helps send blood to the body’s tissues. The heart is a muscle and the most important part of the cardiovascular system. Heart attacks, heart failure, and abnormal heart beat is a serious issue for the cardiovascular system these can sometimes lead to death. These diseases affect the heart and its functions (Heart and Cardiovascular disease 2005).
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
Each system is made up of organs. The lungs, for example, are part of the respiratory system. The heart is an organ in the circulatory system. The liver functions as part of the digestive system and other systems.
