There is a cell in the body that looks like pull and peel, licorice covered in cling wrap. This cell is the cardiac muscle cells. The cardiac muscle cell is in the heart, which is in the cardiovascular system. There are many malfunctions that could possibly happen. There are also lots of structures that have their own function. The cardiac muscle cell is a very complex cell in the body. The cardiac cell is in the heart, which is in the cardiovascular system. The cardiovascular system acts like a highway in your body. This system also includes blood vessels and blood. According to the textbook, Human Biology and Health Prentice Hall Science Explorer it states, “The cardiovascular system also transports cells that attack disease causing microorganisms” (79). This means that this system helps attack diseases that are in your body. It also eliminates waste products that are in the body. The blood in this system will carry different substances that need to be transferred into the body. There are two kinds of blood in the cardiovascular system which are oxygen-poor and oxygen-rich. This is the cardiovascular system. …show more content…
Two common ones are a heart attack and heart valve disease. A heart attack is when there is damage to the heart or death of the heart. This might happen because you smoke, have a high cholesterol, high blood pressure, or a lack of physical exercise. According to Sick some symptoms are uncomfortable pressure, pain that spreads, and chest discomfort. Another malfunction is heart valve disease. The heart valve disease is when the valves in the heart will not close fully which causes the blood not to flow normally. Some symptoms are chest pain, dizziness, low blood pressure, shortness of breath, and abdominal pain. You might get the heart valve disease because you have damage from a heart attack, changes to the heart valve structure, or weakness to the heart valves. These are two malfunctions in the
The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.
The cardiovascular system, which consists of the heart and blood vessels, is the circulatory systems in our body. The major function of the system is transportation; the heart is the system pump and the blood vessels are the delivery routes. The heart transport respiratory gases, nutrients, wastes, and other substances vital to the body’s homeostasis to and from the cells by using the blood as a medium.
Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.
The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The
Coronary artery disease affects the circulatory system. Chemically, this disease develops when blood vessels that are necessary for living become badly damaged. Cholesterol plaques become inflamed in the arteries. The most common signs and symptoms are chest pains which tighten the chest as if someone were standing on it. Shortening of breath also affects those with this disease because the heart is unable to supply enough blood. A major sign of this disease is having a heart attack. This indicates an artery that is completely blocked. This disease is caused by damaging the coronary arteries by smoking, diabetes, high blood pressure or high cholesterol. To diagnose this disease, medical physicians will perform physical exams and examine blood
The cardiovascular system delivers blood, nutrients, ions, gases, and heat throughout your body. The cardiovascular system is a transportation system. It supplies oxygen to the body too and this is the most essential function of the cardiovascular system. http://www.livestrong.com/article/164894-5-major-functions-of-the-cardiovascular-system/ The cardiovascular system has other functions too. It carries digested food from the small intestine to all areas in the body that need it, distributes heat and fights diseases by using white blood cells to fight off
R E V I E W S H E E T 30 Anatomy of the Heart
The cardiovascular system is part of the larger circulatory system, which circulates fluids throughout the body. The circulatory system includes both the cardiovascular system and the lymphatic system. The cardiovascular system moves blood throughout the body, and the lymphatic system moves lymph, which is a clear fluid that’s similar to the plasma in blood.
The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.
Oxygen and nutrients the body requires for function are pumped around this complex network of blood vessels by the heart. At roughly the size of a human fist, the heart is a four-chambered muscle and performs two functions of circulation simultaneously and continuously. Systemic and pulmonary circulation. The heart is made up from three separate layers of cardiac tissue; the outer layer called the pericardium, which is a double sac-like outer covering with serous fluid inside to keep the middle layer, the myocardium from adhering to the outer layer. This middle layer of the heart is the heart muscle which is thicker on the left side, to aid with the pressure needed to sustain systemic circulation. The inner layer of the heart is the endocardium. It’s lining is smooth to help prevent the blood which circulates around the inside of the heart from clotting. The heart is the human body’s in-built pacemaker, and the electrical signals sent through the it cause the heart to contract and relax. This process is triggered by the autonomic nervous system and the contraction and relaxing cycle is
There are three main types of cells that help execute the operations of the cardiovascular system. The first are red blood cells. These cells, as mentioned earlier, carry oxygen to every part of the body, most importantly to the lungs to help us breath. Second, are white blood cells, which are essential for fighting infections. These cells generate antibodies, which are proteins in the blood
The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.

From the very first time the heart starts pounding until the time of death, it may beat more than 3.5 billion times. The center of the circulatory system is the heart. The average heart beats 100,000 times each day, pushing around 2,000 gallons of blood throughout your body. With a life span of 70-90, the heart will beat two to three billion times and circulate 50-65 million gallons of blood.
