CASE STUDY 1 1. The cardiovascular system consists of the following- Blood – It is a red color fluid in the body. Heart – It is also called the control center of our body. It pumps and collects blood to and from the various parts of our body.…
2. Why is the circulatory system important? The circulatory system is important because it transports blood and other materials throughout the body. Without the body does not receive oxygen and the lungs and heart will fail. 3.…
Then, the right atrium then the right ventricle and leaves through the pulmonary arteries to the lungs. Oxygenated blood enters into the pulmonary veins from the lungs and enters the left atrium and the left ventricle then it leaves through the aorta then travels to the rest of the body. In the heart beat there is sinoatrial nodes, atrioventricular nodes, bundles of his, and perkinje fibers. Sinoatrial nodes are a small muscle in the heart that produces some kind of signal. Atrioventricular nodes act as a relay station that controls the heart rate.…
Congestive Heart Failure The heart is fundamentally a blood pump. It pumps blood from the right side of the heart to the lungs to pick up oxygen. The oxygenated blood returns to the left side of the heart. The left side of the heart then pumps blood into the circulatory system of blood vessels that carry blood throughout the body.…
Explain the significance of the thickness of the left ventricular wall. The left ventricle works harder as it pumps blood to the systemic circuit, not just to the pulmonary portions as the right ventricular does. Therefore, the left ventricular walls are thicker, to support the hard work that it has to do throughout the body (Martini & Nath,2014 p.685) The major coronary vessels are on the surface of the heart.…
this concerns is the heart and the system is the circulatory system. These cells, tissues, organs, and organ…
Next to the brain, the heart is the most vital organ in the human body. The brain makes the heart function, but without a heart nothing else functions. In fact, in the absence of brain function, a human body can be kept alive for a surprising length of time as long as the heart can be made to beat. The heart pumps blood through 60,000 miles of blood vessels for a daily volume of 2,000 gallons of blood.…
The study of anatomy and physiology. Anatomy is the scientific term for the study of the body structure and physiology is the term for the study of the function of the body’s organs. During the class, we dissected a pig. We did it to compare the human body and its organ systems with the pig body because they are similar in function. We defined each system and the organs that belong to each one.…
the heart is a complex organ made of muscle and is compromised of four chambers including a right and left atrium and corresponding ventricles. the function of the heart is to pump oxygen rich blood throughout the body while receiving blood and sending it to the lungs to be re oxygenated then repeating the cycle. all of the body's different tissues require this oxygen rich blood to perform their functions. however, there are many problems that can affect the function of the heart. some of these problems are congenital meaning present at birth.…
There are multiple factors that contribute to the build-up of plaque in the vessels and in turn, the development of atherosclerosis (Silverthorn et al., 2009 p327). The disease attacks different arteries in the body, but the most harmful conditions involve damages to the vessels of the brain and the heart (Silverthorn et al., 2009 p329). Understanding of the structures and mechanisms that take place in the heart and the brain to allow for blood distribution is a critical component for anyone trying to determine the development or characteristics of this condition (Silverthorn et al., 2009 p327). In a healthy person, the cardiovascular system is responsible for pumping blood throughout the body accordingly (lecture 4).…
The heart in our body is what keeps us going. If our heart stops beating, we pass out and die. There are many diseases that are related to the heart. There are three different kinds of vessels in our body, arteries are one of the three, and the other two are veins and capillaries.…
The structure of the blood is as follows: Four major parts Plasma, red blood cells, white blood cells, and platelets. What is plasma it is made up of water 90%-92%? The fluid is the color as straw. The function of the blood system is to transport the dissolved gases such as oxygen and carbon dioxide it rids the body of water products.…
In this assignment I will be explaining the physiology of two body systems, the cardiovascular system and the respiratory system in the relation to energy metabolism in the body. Energy metabolism is where energy is generated from nutrients and delivered to the organs around the body. Energy is needed in the body in order muscular movement, circulation of the blood, lymph and tissue fluid, breathing process, cell growth and repair, the transition of nerve impulses and for the building of different complex molecules. The cardiovascular system There are four major functions of the cardiovascular system, these include: the transportation of nutrients, gases and waste products around the body, the protection of the body from infections and blood…
system, principally cardiac disease, vascular diseases of the brain and kidney, and peripheral arterial disease. The causes of cardiovascular disease are diverse but atherosclerosis and/or hypertension are the most common. In addition, with aging come a number of physiological and morphological changes that alter cardiovascular function and lead to increased risk of cardiovascular disease, even in healthy asymptomatic individuals. Heart attacks and strokes are usually acute events and are mainly caused by a blockage that prevents blood from flowing to the heart or brain.…
The heart is an essential part of a human’s body. It is a muscular organ located at the center of the circulatory system that pumps blood throughout the body. The system comprises of veins, arteries, and capillaries, and these blood vessels carry blood to and from all areas of one’s body to sustain life. It beats around 100,000 times and pumps around 2,000 gallons per day. The heart is vital to one’s health and everything that goes on in his or her body.…
