Answer 1

hello dear
Chambers of the Heart

The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system

The heart has four chambers:

The right atrium receives blood from the veins and pumps it to the right ventricle.The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.The left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure

Answer 2

The heart -A muscular organ: The heart of human being is an elongated conical structure which is located between both the lungs in thoracic cavity, slightly toward left side. The heart is made of four chambers . These are left and right atria on the upper side and left and right ventricles, on the lower side
Oxygenated blood is brought into the left atrium of the heart from lungs . The right atrium receives deoxygenated or impure blood from all parts of the body . There in a septum. called interauricular septum between both the atria . Similarly an interventricular septum is found between both the ventricles .The valves present between atria and ventricle ensure prevention of back flow
