The heart is a cone-shaped organ located in the chest cavity between the lungs. It is surrounded by the pericardium and pumps blood through the arteries and veins. The heart wall consists of three layers - the epicardium, myocardium, and endocardium. The myocardium contains cardiac muscle that allows the heart to contract and pump blood. The heart is divided into four chambers - the right and left atria receive blood, and the right and left ventricles pump blood to the lungs and body. Valves between the chambers allow blood to flow in one direction. The conducting system coordinates heart contractions and uses electrical signals to stimulate contractions.

Anatomy of the heart
The heart contains four chambers - two upper chambers called atria and two lower chambers called ventricles. The atria receive blood from veins into the heart while the thicker-walled ventricles pump blood out of the heart and into arteries. There are three types of circulation - systemic circulation pumps oxygenated blood from the left ventricle to the body, pulmonary circulation pumps deoxygenated blood from the right ventricle to the lungs, and hepatic portal circulation transports blood from the intestines to the liver. Valves between the chambers regulate blood flow through the heart.
The Anatomy Of Heart
The document discusses the anatomy and function of the human heart. It describes the heart as a hollow muscular organ composed of cardiac muscle and connective tissue. It has four chambers - two atria that receive blood and two ventricles that pump blood out of the heart. The right side receives deoxygenated blood and pumps it to the lungs, while the left side receives oxygenated blood and pumps it to the body. The heart beat is regulated by the sinoatrial node, which generates electrical impulses that cause rhythmic contractions and allow blood to continuously circulate through the body.

Anatomy Of The Heart
The heart is a hollow muscular organ responsible for pumping blood through the body. It is enclosed in a sac called the pericardium and located in the mediastinum cavity in the center of the chest. The right side of the heart collects deoxygenated blood from the body and pumps it to the lungs, while the left side collects oxygenated blood from the lungs and pumps it out to the body. The heart's rhythm is controlled by electrical signals that cause the muscles to contract, originating from a pacemaker in the right atrium and traveling through conduction pathways.
Heart Anatomy
The heart is a hollow muscular organ that pumps blood through the blood vessels. It is located in the mediastinum of the thoracic cavity. The heart is surrounded and protected by the pericardium, which has inner and outer layers. Within the heart are four chambers - two upper atria that receive blood and two lower ventricles that pump blood out. Valves between the chambers prevent backflow of blood. The heart is supplied with oxygenated blood by the coronary arteries.
Anatomy of the heart
This document provides an overview of heart anatomy including its location, size, layers, chambers, and blood flow. It describes that the heart is located in the mediastinum between the lungs, weighs 250-300 grams, and has two layers - the outer fibrous pericardium and inner serous pericardium which separates it into a pericardial cavity. Internally, the heart is divided into four chambers - two upper atria which receive blood and two lower ventricles which pump blood out. The left ventricle is thicker walled due to pumping blood throughout the higher pressure systemic circulation.
Anatomy of the heart
The document summarizes the structure and anatomy of the heart. It describes the location and orientation of the heart in the thoracic cavity. It then discusses the layers that cover the heart, including the fibrous and serous pericardium. It provides details on the chambers of the heart, including the right and left atria and ventricles. It also describes the valves of the heart, including the tricuspid, bicuspid, pulmonary, and aortic valves. Finally, it summarizes the coronary arteries that supply blood to the heart muscle and the veins that drain blood from it.
The heart walls
The heart wall consists of three main layers - the endocardium, myocardium and epicardium. The endocardium lines the inner chambers, the myocardium is the thick middle layer of muscle responsible for contractions. The epicardium is the outer layer. Damage to layers can cause conditions like endocarditis (endocardium inflammation), myocarditis (myocardium inflammation) and angina or heart attack due to reduced blood flow from blocked arteries.
coronary circulation
The coronary circulation supplies blood to the heart muscle. Blood flows through the right and left coronary arteries which branch from the aorta. Coronary blood flow increases during cardiac diastole as pressure in the intramural vessels is released, allowing more blood to enter the myocardium. Disruptions to coronary blood flow can cause myocardial ischemia, infarction, and angina pectoris due to insufficient oxygenation of heart tissue. Coronary occlusion from atherosclerosis is a leading cause of restricted blood flow and these downstream effects.
Anatomy of the heart
The heart is pyramidal in shape with an apex pointing leftward and downward. It has four chambers - two atria which receive blood and two ventricles which pump blood. The right atrium receives deoxygenated blood from the body and pumps it to the right ventricle to be sent to the lungs. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle to be sent to the body. Blood flows through the heart via the tricuspid, bicuspid/mitral, pulmonary and aortic valves. The heart's conduction system coordinates contractions and is composed of the sinoatrial node, atrioventricular node and bundle of His.
Great vessels artery
The document describes the major blood vessels of the thorax, including the aorta, pulmonary trunk, and superior vena cava. It details the anatomy and branches of each vessel. The aorta originates from the left ventricle and divides into the ascending aorta, aortic arch, and descending thoracic aorta. The pulmonary trunk carries deoxygenated blood from the heart to the lungs, where it divides into right and left pulmonary arteries. The superior vena cava returns oxygenated blood from the upper body to the heart.
Anatomy of right atrium
This document provides an anatomical overview of the right atrium, right ventricle, pulmonary valve, and tricuspid valve. It describes the external features and internal structures of the right atrium, including its tributaries that receive venous blood. It notes the smooth posterior sinus venarum and rough anterior pectinate part. It also describes the components, surface markings, and location of the tricuspid and pulmonary valves. Finally, it outlines the triangular shape of the right ventricle and notes its inflowing and outflow parts, as well as the muscular ridges within.

The document provides information about the anatomy and physiology of the heart. It discusses the following key points in 3 sentences:
The heart is a muscular organ located in the mediastinum that pumps blood through the circulatory system via four chambers - two upper atria and two lower ventricles. It has three layers - epicardium, myocardium and endocardium - and is surrounded by the pericardium. The heart has a conduction system including the sinoatrial node which acts as the pacemaker, generating electrical impulses that cause coordinated contractions of the atria and ventricles to efficiently circulate blood.
Cardiovascular System
The human heart heart length, width, and thickness are 12 cm, 8.5 cm, and 6 cm, respectively. In addition, the mean weight of the heart is 280-340 g in males and 230-280 g in females.
Thoracic aorta
The thoracic aorta begins where the aortic arch ends at the fourth thoracic vertebrae and extends down to the diaphragm. It supplies blood to the thoracic cavity and has several important branches including the bronchial arteries which supply the lungs, esophageal arteries which supply the esophagus, and posterior intercostal arteries which supply the spaces between the ribs. The thoracic aorta also gives off mediastinal and pericardial branches before passing through the diaphragm and becoming the abdominal aorta.
The aorta
The aorta is the largest artery that carries oxygenated blood from the left ventricle throughout the body. It can be divided into four sections - the ascending aorta, aortic arch, thoracic aorta, and abdominal aorta. The aortic arch arises from the ascending aorta and curves superiorly, posteriorly and to the left before descending as the thoracic aorta. It gives off three branches - the brachiocephalic trunk, left common carotid artery, and left subclavian artery. The thoracic aorta continues down through the thoracic cavity and passes through the aortic hiatus in the diaphragm to become the abdominal aorta.

Final heart
The cardiovascular system circulates blood throughout the body using the heart as a pump. The heart has four chambers - two upper atria and two lower ventricles. It is surrounded by membranes and tissues. Blood enters the right atrium from the body, then passes to the right ventricle which pumps it to the lungs. Oxygenated blood returns to the left atrium and passes to the left ventricle which pumps it out to the body via the aorta. The heart contracts over 100,000 times per day to circulate blood through the pulmonary and systemic circuits. Valves ensure blood only flows in one direction through the heart.

Introduction to the_cardiovascular_system
The cardiovascular system transports blood throughout the body using a two-circuit pathway. The pulmonary circuit pumps deoxygenated blood to the lungs for oxygenation and returns it to the left side of the heart. The systemic circuit then pumps oxygenated blood from the left side of the heart through arteries to tissues throughout the body to deliver oxygen and nutrients. The heart is divided into four chambers and uses valves to ensure one-way blood flow and prevent backflow between chambers.
