Atrium

into the ventricular chamber. It is located between the right atrium and right ventricle and its function is to close off the right atrium that holds blood coming in from the body and opens to allow blood to flow from the top right atrium to the right ventricle. The left AV valve also referred to as the bicuspid or mitral valve is located between the left atrium and left ventricle. The function of this valve is to close off the left atrium

In a sweeping fashion, the right atrium contracts and forces the final volume of blood into the right ventricle. The left atrium contracts and contributes the final 20% of volume to the left ventricle. The S-A node signal is delayed by the atrioventricular node to allow the full contraction of the atria that allows the ventricles

in the pericardial sac and has four chambers namely right atrium, right ventricle, left atrium and left ventricle and is separated into left and right side by a muscular wall called septum. Interatrial septum separates the two atria and interventricular septum separates two ventricles. The heart wall has three layers epicardium, myocardium and endocardium. Two large veins such as superior vena cava and inferior vena cava open in right atrium. Atria are superior, and ventricles are located inferiorly

the atrium blood entering. The inferior chambers are the ventricle blood exiting. On the right side, there is the right atrium and right ventricle and on the left side there is the left atrium and left ventricle. The right side allows the circulation of deoxygenated blood from the body and sends it to the lungs. The left side circulatory blood gets oxygenated blood from the lungs and supplies the body with blood. The two heart valves the atrioventricular valves are position between the atrium and

Another smaller atrium can be accessed through a doorway on the right of the primary atrium. This atrium contains the house's lararium, or a shrine to the family's Lares. This lararium depicts the Genius of the household making a sacrifice and surrounded by two Lares. Underneath is a large snake

also surrounded by a membrane called the pericardium. This membrane consists of a thin film of fluid to prevent the heart from friction. The heart consists of double pumps. Each pump is made of two chambers. The upper muscular chamber is known as atrium and the lower chamber is called ventricle. The heart also consists of blood vessels known as aorta, vena cava, pulmonary trunk and pulmonary veins. (Taylor, 2017) Blood is a liquid connective tissue, that transports substances through the body. It

ancient Rome to have an "atrium" and "peristylium." These two parts of the Roman house were important. Its primary function is to ventilate the corridors and rooms. This types of houses were common designs in both urban and rural areas. On other hand, there were also big houses which refers to"villas," where the rich people lived. In addition, there were also tenement houses where poor people live, particularly to the household workers or slaves ( The Romans web, n.d). Atrium is an open space with

Roman Domus A Roman Domus was an ancient Roman house. It was usually owned by wealthy Roman families, and contained a countless number of rooms and wings. The average Roman Domus contained a Vestibulum, Taberna, Atrium, Tablinum, Trinclinium, Peristylium, Exedra and several alae and cubiculums. However, the Domus was not just a place where wealthy families lived. It was also a place of business and religious ceremonies. Roman Domuses were usually built so that that they did not face the street

parts of the heart. When blood travels from the tissues to the heart, it goes through the vena cava vein and into the heart. The blood travels from the rights atrium to the right ventricle. Once the ventricle fills up with blood, the papillary muscle help

heart into the arteries that exist from the ventricles. The Heart has four valves that regulate blood flow through your heart. The two valves that separate the atria from the ventricles are the atrioventricular valves. The valve between the left atrium and
