Anatomy and Physiology of the Heart The bosom is an indispensable organ that is responsible for pumping blood all throughout the organic structure and providing it with O and foods; it is the cardinal hub for the cardiovascular system and acts as the conveyance system of the organic structure, which performs via electrical conductivity activity ( Burke et al.
As it leaves the heart, the blood carries with it oxygen and nutrients to the body and brings back metabolic wastes from the body cells1,2. However, much as it supplies blood to the rest of the body, the heart itself needs blood to support its metabolic activity. The heart is thus supplied by the coronary arteries which branch off from the aorta.
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 of the Heart. Anatomy of the Heart. Essay that explains how each part works to provide a completely functioning pump. Include how substances are exchanged between blood in capillaries and the tissue fluid surrounding body cells, and compare the pulmonary and systemic circuits of the cardiovascular system. The heart weighs between 7 and 15 ounces (200 to 425 grams) and is a little.The human heart is pinkish about the size of a fist and weighs approx. 300 gms, the weight in females being about 25% lesser than the males. It is a hollow, highly muscular, cone-shaped structure located in the thoracic cavity above the diaphragm in between the two lungs.

The heart is supplied with arterial blood by the right and left coronary arteries. On the contrary, its deoxygenated blood or the venous return is by the coronary sinus which empties into the right atrium. Functions: The function of the heart is to maintain a constant circulation of blood throughout the body.
OVERVIEW This page is dedicated to covering how the heart will appear across different radiological studies. CHEST X-RAY A chest X-ray is a very routinely ordered study, and a core component of reading a chest X-ray is to evaluate the appearance of the heart. One of the initial evaluations can be to check the size of the heart. The. Read more Radiological Anatomy: Heart.

The heart is an organ that pumps and circulates blood all over the body through a circulatory system to supply nutrients and oxygen to the body tissues and excrete carbon dioxide alongside other wastes.The human heart is in the chest where it lies between the lungs and above the diaphragm, just behind the sternumand is encased by the pericardium that protects it and supports the inside part of.
Coronary CTA protocols usually image the heart using cranial-to-caudal acquisition ().However, caudal-to-cranial scanning acquisitions are implemented when concomitant imaging of the pulmonary arteries is desired in patients with atypical chest pain ().We describe both of these protocols because the cardiac venous anatomy may be displayed with variation in enhancement depending on the type of.
