Question

Answer 1

Hint: A hollow muscular organ located in between 2 lungs .It has four chambers ,4 valves ,2 atriums and 2 ventricles and two pumps on right and left side. The weight male and female hearts are different. an adult's heart beats about 60 to 80 times per minute and in newborn babies heart beats faster than an adult's about 70 to 190 beats per minute.

Complete answer:
To answer this question you must know the anatomy of the heart. The human heart is mesodermal in origin and the heart is a hollow muscular organ made up of special types of muscles called cardiac muscles and cardiac muscles have the ability of contraction and relaxation. It is located in between two lungs .

It measures about 12 cm in length ,9 cm in breath and about 6 cm thick and the size of the heart is roughly the size of one’s closed fist. The average weight of the human heart is about 250 to 350 grams. in male heart weight is around 280 to 340 and in females ,it weighs around 230 to 280 grams. And an infant's heart is about a thirtieth of total body weight.

Heart is reddish brown in color and shows three layers namely pericardium ,myocardium and endocardium. It has four chambers, the upper two are called atria and the lower two are called ventricles. Atria are receiving chambers and ventricles are distributing chambers.

Therefore the correct answer is 250 to 350 grams.

Note: On average ,the heart beats about 100,000 times a day ,i.e ,around three billion beats in a lifetime. It is important to note that the blood pumped by the heart also circulates other important substances such as nutrients, hormones. It collects deoxygenated blood from all parts of the body ,and carries it to the lungs for oxygenation.
