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.

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.

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
