picking up waste. The elements of the system include; The Heart The heart acts as a muscular pump which is divided into 4 different chambers, the heart's main function is to pump the blood around the body. It pumps deoxygenated blood through the veins, to the lungs for oxygenation which can then be pumped into the various arteries. The transported blood therefore transports oxygen, hormones and nutrients to body tissues. The four chambers in the heart are known as the right atrium, left…

fluid loss occur in many different ways, however because the most common cause is of severe blood loss, it is best to first discuss types of hemorrhage and the care that follows. Severe hemorrhage is most often caused by a tear in a major artery or vein that are located deep below skin and muscle tissue (Red Cross 160). A tear can be result of an external wound or from damage to internal structures, both display different symptoms and require different…

A) Explain why transport systems are required in the body? The reasons as to why transport systems are required in the body is because it allows the body to be able to respire and be able to get all that it needs to maintain the same state, for example, oxygen throughout the body as well as nutrients to the cells in the body. An example of a transport system is the Respiratory system. This system is required in the body as it helps the body to take in oxygen, this can be done through the lungs,…

forming blood clots to prevent excess blood loss, carrying cells and antibodies that fight infection, bringing waste products to the kidneys and liver, which filter and clean the blood, and regulating body temperature. The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells. About 7 to 8 percent of your total body weight is blood. An average-sized man has about…

Over the years, biologists have carried out experiments to explore the differences in animal hearts. With regards to this experiment at hand, the differences were explored between mammalian and amphibian hearts. This experiment also helps us determine the effects of external, biological factors and pharmacological substances on the contraction of the heart. The following will serve as an overview of the structure and functioning of amphibian heart. A frog heart has three chambers (two atria and…

Breathing air in and out is the first step to the respiration process. Respiration is a series of metabolic reactions and processes that take place within the cells of organisms. The organisms store biochemical energy within adenosine triphosphate (ATP) molecules. For the process to being, we must first draw air into our lungs. The lungs muscles contract and expand the chest cavity, causing a negative or hypotonic pressure within the pleural cavity. The hypotonic pressure then forces the lungs…

The heart’s role for the entire body is not only limited to pumping blood. It also needs its own blood supply to be able to perform its several functions. The process of the heart managing its own blood supply is known as coronary circulation. The walls situated in the heart have systemic blood vessels. These exist to meet the needs of the heart for blood supply. Oxygenated blood is brought to the myocardium via the left and right coronary arteries. They are also responsible for bringing the…

To diagnosis AS a transthoracic echocardiogram (TTE) is completed, with two dimensional doppler (2D). An Echocardiogram is a diagnostic study that uses ultrasound waves transmitted through a transducer using a conducting gel to create an image of the heart. Ultrasound waves are cyclic in nature and at a frequency that are not audible within the parameter of human hearing (Fridman, V., 2013). The transthoracic approach provides visualization of the heart and its structures. Throughout TTE the…

I chose to take a brief look at coronary procedures involving grafts. To answer the question first we need to understand some of the differences in veins and arteries. The arteries in the systemic system, deliver oxygenated blood from the heart, in a high pressure low volume stream to the capillaries found throughout the body. The systemic veins carry the deoxygenated blood from the capillary beds in a low pressure, high volume, valve controlled flow, back to the heart. From there, the heart…

Cardiovascular Response: When exercising the muscles requires a constant supply of oxygen, it is the hearts job to make sure there is enough oxygen being pumped round the body for the muscles, the heart has to pump harder and faster as more oxygen is required to get round the body to the muscles in use otherwise they will fatigue quicker. If this is repeated regularly, then over time the heart will become stronger as will become more used to the higher demands. At the start of exercise, the…
