Task 2 Part A Cebita Santhosh Q1. The three main types of blood vessels in the circulatory system are veins, arteries and capillaries. The veins carry deoxygenated blood from the capillaries back to the heart. The arteries carry blood away from the heart to your tissues. The capillaries are the smallest of the body's blood vessels, only one cell thick and are found in the muscles and lungs.…
M1 outline the adaptations to cardiovascular, respiratory, musculoskeletal and energy systems, brought about by regular exercise Cardiovascular System The cardiovascular system consists of the blood vessels and the heart. They function is to circulate the blood around the body to all the muscles. The red blood cells carry oxygen to all the muscles through the vein (carries blood to the heart). The veins have thin walls and contain blood under the low pressure.…
A case study of asthma in a 10 year old European child. This case study will cover the normal structure and function of the respiratory system. This case study will also discuss the changes that occur when asthma is triggered, and the routine diagnostic tests/vital signs for asthma. The normal range of the routine tests/vital signs for asthma and three nursing interventions that are required to meet the clients needs in relation to asthma will be explained further.…
Mammals inhale oxygen though their mouth as part of ventilation and exhales carbon dioxide. The air travels down the trachea before it branches off into the two bronchi. Branching off the bronchi are the bronchioles that transport the air to the alveoli where gas exchange takes place. The alveoli are air sacs.…
The right atrium gets blood from the systemic circuit and passes it to the right ventricle and it pumps blood to the pulmonary circuit. The left atrium collects blood from the pulmonary circuit and empties it into the left ventricle which then pumps blood into the systemic circuit. 39. Pericardial inflammation results in a production of pericardial fluid. The fluid builds u in the pericardial cavity, which restricts movement of the heart, and this is known as cardiac tamponade.…
About the size of a large fist, heart is made up of cardiac muscle, myocardium, with skeletal muscle-like striations. It has two upper atria & two lower ventricles separated vertically by septum, and four main valves with which the blood makes its directional flow into and out of the heart. Deoxygentated blood with which the blood flows into and out of the organ. Deoxygenated blood enters through the venae cava fills the right atrium (RA) and right ventricle (RV) through the tricuspid valve. Then, RV contracts pushing the blood to pulmonary circuit and returns oxygenated from the lungs and travels to left atrium (LA) and left atrium (LA) through the mitral valve.…
Finally! The AV bundle fires and we pump through the pulmonary semilunar valve into the pulmonary trunk and out the pulmonary arteries. We are on our way back to the lungs now. It gets a little small again as we pump through the pulmonary arterioles and into the capillaries. Here we have our last gas exchange with the capillaries.…
Total Anomalous Pulmonary Venous Return Total anomalous pulmonary venous return (TAPVR) is a heart condition that children are born with (congenital). The blood vessels that are supposed to carry blood from the lungs to the left side of the heart go to the right side instead. In a normal heart, blood returns to the right side of the heart from all over the body. The right side of the heart pumps blood to the lungs, where the blood picks up oxygen.…
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.…
When the right atrium contract the blood flows through the tricuspid valve and into the right ventricle. When the right ventricle contracts the blood passes the pulmonary semilunar valve, into the pulmonary artery, and the blood is going to the lungs. The blood goes through a process in the lungs and the blood become oxygenated. The oxygenated blood is returned to the heart from the pulmonary vein and goes into the left atrium. When that atrium contracts the blood asses the mitral (bicuspid) valve and goes to the left ventricle.…
Once filled, the right atrium contracts and pumps its contents into the right ventricle through the tricuspid valve. Once the right atrium is drained completely, the tricuspid valve will close to prevent blood from flowing back into the right atrium. Next, the right ventricle contracts, causing the pulmonary valve to open and forcing blood into the pulmonary artery. Once the blood is emptied, the pulmonary valve will close to prevent backflow. The deoxygenated blood will travel to the lungs through the pulmonary artery to pick up oxygen and release carbon…
The pulmonary circuit carries deoxygenated…
The Cardiovascular System: An Overview of Blood, Vessels, and Heart – Healthy to Diseased The cardiovascular system, also known as the circulatory system, consists of the heart, blood, and blood vessels (Mertz, 2004). The cardiovascular system moves oxygenated blood and nutrients through to and removes carbon dioxide and wastes out of the body’s cells. (Miracle of the Human Body, 2010) I will provide an overview how a healthy cardiovascular system does this by first discussing the anatomy of it, in a healthy state, and then the physiology of it, also in a healthy state, this will include how the pulmonary and systemic circuits work.…
These tubes end in bunches of tiny alveoli air sacs. Capillaries run through the air sacs walls the air move the air sacs as oxygen to stream the air sac walls into the blood back into the capillaries. When…
3. Describe the mechanisms of external respiration including the interchange of gases within the lungs. The job of the lungs is to transfer oxygen to the blood and to remove waste carbon dioxide from it. To do this the lungs contain millions of alveoli where gas exchange takes place.…
