I. ANATOMY AND PHYSIOLOGY OF THE HEART I. LOCATION OF THE HEART The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist‚ and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava‚ the pulmonary artery and vein‚ as well as the aorta. The aortic arch lies

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart‚ which is a muscular pumping device‚ and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body. The Heart * The heart

General Biology In Class Quiz - Chapter 5 10 points 1. Explain the difference between chromatin‚ chromosome‚ nucleosome and histones. Chromatin- is the combination of DNA‚ histone‚ and other proteins that make up chromosomes. Chromosome- is minimally very long continuous piece of DNA which contains many genes regulatory elements and other intervening nucleotide sequences. Nucleosome- is considered to be one of the most stable particles in the DNA that helps in the compacting and transcripting

1. Consider the equation F = DP/R. It describes the flow (F) of fluid in a tube in which there is a pressure difference (DP) between the two ends and a resistance (R) to flow. The equation indicates that(2.0 Score ) A.the flow of fluid from point A to point B in a tube depends upon the difference in pressure between A and B. B.the flow of fluid in a tube depends upon the absolute pressure at the beginning of the tube. C.the greater the resistance to flow in a tube‚ the greater the flow for any

Anatomy and Physiology are probably 2 of many different sciences necessary for the best understanding of the human body and how it functions. So I believe that in order to compare two things‚ you need to explain what each are first. ANATOMY is the study of the human body. It can also be defined as being the study of how various parts of the body interact and work together. PHYSIOLOGY is the study of how living organisms function. That includes nutrition‚ movement‚ and reproduction. So you are pretty

Unit 5: Anatomy and Physiology (P4) Explain the physiology of two named body systems in relation to energy metabolism in the body In this task I am going to discuss the three systems involved in energy metabolism in the body. The chemical equation for cellular respiration is: C6H12O6 + O2 = E + CO2 + H2O OR Glucose + Oxygen = Energy + Carbon Dioxide + Water In order to release energy we need glucose which is a simple carbohydrate that is produced after digestion of food and we also need oxygen
