The Circulatory System
The circulatory system works as the body’s transportation network, tirelessly sending nourishment and protection to all vital parts. According to Merriam-Webster, the circulatory system is “the system of blood, blood vessels, lymphatics, and heart concerned with the circulation of the blood and lymph.” While many may already be familiar with the circulatory systems’ role in the transport of oxygen, it does much more. In reality, the circulatory system is built of two subsystems: the lymphatic system and the cardiovascular system. The cardiovascular system and the lymphatic system work in tandem to make sure the body is free from attacking microorganisms and receives oxygen, respectively. However, due to the circulatory playing such a crucial role in the way the body operates, issues are bound to arise, and it is imperative for one to know precisely how to prevent such complications from arising.

The cardiovascular system is the most commonly known …show more content…

Most of blood, however, is actually made of plasma, a heat conducting liquid that protects the red blood cells, which deliver the oxygen. The smallest percentage of blood content is white blood cells, which are responsible for finding and killing foreign microorganisms. Carrying blood, two types of vessels (tunnel-like structures that contain blood) contribute to the majority of blood flow: arteries, which take blood away from the heart, and veins, which bring blood to the heart. When ventricles in the heart contract, blood pressure results, causing these vessels to become more strained as more blood enters them (also creating pulse as a result). Blood is moved through the body by two veins, including the pulmonary system that takes blood to the lungs, and the systemic system that takes blood everywhere else (systemic system contains many subsystems). Blood is essential in bringing much needed resources to the

  • Analysis and Description of Hematologic System

    The Hematologic System is regarded as the body’s system that regulates the movement of nutrients, molecules (macro and micro molecules), and oxygen to tissues and metabolic waste products and carbon dioxide out of the tissues (Colbert, 2009). The overall role of the hematologic system is to deliver substances needed for cellular metabolism, temperature regulation, defend the body from injury and microbial infections, and maintain the homeostatic balance or acid-base chemistry of the blood and fluid-electrolyte balance. The Hematologic System is principally made up of the blood, blood vessels, and primary organs that manufacture blood cells such as the bone marrow, spleen, lymph nodes, liver, and thymus gland (Ignatavicius & Workman, 2009). Blood is made up of three distinct components: red blood cells, white blood cells, and plasma, and its role is to transport necessary substances for metabolism (nutrients, hormones and oxygen) to cells and to remove metabolic waste products and carbon dioxide, regulation of body temperature and fluid balance, and protect the body from infections. Blood vessels simply aid the transportation of blood throughout the body, simply in and out of the heart. Spleen on its part is the largest lymphatic organ and functions as the blood filtration system and reservoir, site for fetal hematopoiesis, and mounts immune responses that act against invading infections. Bone marrow is another important component of the hematologic system, and its role is to synthesize new blood cells (Red blood cells white blood cells, and platelets) that constitute a healthy blood count while the liver functions by detoxifying the blood (Colbert, 2009).

    According to Virtual Medical Centre (2014) the primary function of the blood is to act as a transport, to give the body protection and to help regulate. The blood dissolves gases such as oxygen and carbon dioxide. The blood also transports vital nutrients throughout the body, such as micro-nutrients, fatty acids and amino acids. The flow of the blood helps to regulate the body’s temperature. Also the blood removes wastes material of metabolism. Blood cells (white and red cells) are carried through the body to help with the body’s natural defense, blood clotting and the carry anti-bodies.

    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 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 lymphatic system is a vital and integral part of the cardiovascular system”. The lymphatic system contains many structures which consist of lymphatic vessels, lymph fluid, lymph cells, lymph nodes and other substances. (Hastie, 2012) The lymphatic system consists of a network of fine tubes or vessels which ramify throughout the body similar to blood vessels. Unlike the blood the fluid is moved by the muscles and limbs. The lymph vessels have fine walls, so water can pass easily through them. The main role of the lymphatic system is too drain off excess fluid from all parts of the body. This prevents the cells getting waterlogged. (Hayes, 2002). Other functions include returning the lymph back to the heart and immune surveillance within

    The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make

    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 history of anatomy and physiology dates back to ancient Egyptian times when humans were mummified after death and bodies would be stripped of their internal organs during the embalming process. It was not until much later when Hippocrates II, known as the father of medicine, was the first to write about human anatomy. Shortly after that, the Alexandrian Medical School was established, where human dissection was allowed for the first time, which promoted research and new discoveries in the field. From there, many other influential researchers came up with theories regarding the cardiovascular and nervous systems, etc; however, the missing links in some of the earlier theories was found with the discovery of the microscope, which changed the focus of research and led to many advancements in the field.

    The human heart is one, if not the most, vital organ in the human body. The heart pumps blood through the circulatory system. It is what provides the body with oxygen and nutrients. Of course, without this important, muscular, organ there would be no way to survive. “Everyday your heart beats about 100,000 times, sending 2,000 gallons of blood surging through your body. Although it is no bigger than your fist, your heart has a mighty job of keeping blood flowing through 60,000 miles of blood vessels that feed your organs and tissues” (Watson n.pag.). Any type of damage or restriction to the heart or its valves can reduce pumping. Cardiovascular diseases are examples that cause damage to the heart and blood vessels. Cardiovascular disease is the most common cause of death globally, accounting for thirty percent of deaths. Since the heart has such an important role in the human body, it is critical that it is functioning and working properly. An important medical test used to observe the heart is called transesophageal echocardiography, also known as TEE.

    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
