Question

Explain structure , location and function of the human heart ?

Answer 1

Hi There,
Here's your answer...

Heart is a muscular organ which transports Oxygen and Carbon dioxide. Oxygen rich blood from the lungs comes to the left Atrium through the pulmonary veins. The left Atrium relaxes when it is collecting this blood and passes the blood to the left ventricle. at that time left ventricle also expands. From here blood is transported by the hour to two different parts of the body.
The deoxygenated blood comes from the inferior and superior Vena cava from the body parts to the right Atrium and it expands.As right Atrium contracts the corresponding right ventricle also dilates and the blood is transferred to the right ventricle which in turn Pumps it to the lungs for oxygenation through Pulmonary artery.
Valves ensure that blood does not flow backward when the atrium or ventricle contracts.....

Hope it helps...

Answer 2

Structure of human heart :-
The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the Superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.

Location of human heart :-
  In humans, the heart is located between the lungs, in the middle compartment of the chest.

Function of human heart :-
The heart is a pump, which moves the blood. The arteries and veins are the pipes through which the blood flows. The lungs provide a place to exchange carbon dioxide for oxygen. The heart is a hollow, muscular organ, which functions as a pump for the movement of blood through the body.

I hope this answer was helpful to you.........
