keep them in physiological limits. To achieve this‚ every organ works together and thus the body works together as a whole. This requires body to communicate with the organs‚ this is established through two very highly specialized systems; nervous system and endocrine system‚ they use electrical impulses and hormones to communicate respectively1. It is vital for our body to maintain homeostasis for our survival‚ this ability of the body allows us to adapt to our environment which is why we can live

NumberStructureCharacteristics Function 1Left ventricleIt is the thickest of all the chambers. After flowing into the left atrium and through the mitral valve‚ blood enters the left ventricle before it is pumped out through the aortic valve into the aortic arch and onward to the rest of the body.Pumps oxygenated blood to tissues all over

Case Study # 2: Age-Related Changes that Occur in the Cardiovascular System Sarah Miller ITT Technical Institute As the heart ages it goes through changes such as thickening of the walls‚ slowing heart rate‚ decrease in maximum heart rate‚ loss of efficiency in pumping. The layers of the heart include the pericardium‚ epicardium‚ myocardium‚ and endocardium. The pericardium is the membrane that protects; it is a sac that the heart sits in and has a layer of fluid between for shock and absorption

REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to

Ginkgo biloba affects the cardiovascular system and the central nervous system. Elasticity of the blood vessels‚ from the largest arteries to the smallest capillaries‚ improves the circulation in the limbs and brain. Similarly‚ acetylsalicylic acid acts by reducing blood viscosity and by reducing the risk of blood clots. It also has antioxidant properties. It removes free radicals and protects healthy blood cells. Some researchers claim that it supports the nervous system. increasing the supply of

CARDIOVASCULAR FITNESS Cardiovascular fitness is frequently considered the most important aspect of physical fitness because those who possess it are likely to have a lessened risk of coronary heart disease – the number one killer in our society. Cardiovascular fitness is also referred to as cardiovascular endurance‚ cardio-respiratory capacity and circulatory fitness. Regardless of the word used to describe it‚ cardiovascular fitness is complex because it requires fitness of several body systems

The function of the digestive system is to absorb and assimilate key nutrients which are required to maintain and regulate other systems in the body. Enzymes secreted within the digestive system have a role of breaking down food from proteins into amino acids‚ starch into glucose and fats into a mixture of fatty acids and glycerol. The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed through the mouth and nostrils into the

Age Related Changes that Occur in the Cardiovascular System Age Related Changes that Occur in the Cardiovascular System In the normal conduction of the heart the electrical impulse starts in the SA node‚ also called the pacemaker of the heart. The electrical impulse travels through the right atrium and through the Bachmann’s bundle into the left atrium. This stimulates the atria to contract. Next the signal travel to the AV node. The AV node slightly delays the signal. This delay is needed

Describe the physiology of the cardiovascular system in relation to energy. A.T.P is stored‚ chemical energy in the cell‚ without A.T.P we would die. To make A.T.P we need glucose oxygen. Carbon dioxide and heat are the waste products. The main function of the cardiovascular system in relation to energy is to transport the oxygen and glucose to the cells‚ and to transport the waste products such as carbon dioxide and urea (waste product from protein digestion) away from the cells and to the lungs
