Q3. In order to avoid the mixing up of carbon dioxide rich blood and oxygen rich blood,
our heart has four chambers. Name these four Chambers and also explain how does blood
circulate among these four Chambers?
Answers
Answer:
The heart’s chambers
The heart’s four chambers function as a double-sided pump, with an upper and continuous lower chamber on each side of the heart.
The heart’s four chambers are:
Right atrium. This chamber receives venous oxygen-depleted blood that has already circulated around through the body, not including the lungs, and pumps it into the right ventricle.
Right ventricle. The right ventricle pumps blood from the right atrium to the pulmonary artery. The pulmonary artery sends the deoxygenated blood to the lungs, where it picks up oxygen in exchange for carbon dioxide.
Left atrium. This chamber receives oxygenated blood from the pulmonary veins of the lungs and pumps it to the left ventricle.
Left ventricle. With the thickest muscle mass of all the chambers, the left ventricle is the hardest pumping part of the heart, as it pumps blood that flows to the heart and rest of the body other than the lungs.
The heart’s two atria are both located on the top of the heart. They are responsible for receiving blood from your veins.
The heart’s two ventricles are located in the bottom of the heart. They are responsible for pumping blood into your arteries.
Your atria and ventricles contract to make your heart beat and to pump the blood through each chamber. Your heart chambers fill up with blood before each beat, and the contraction pushes the blood out into the next chamber. The contractions are triggered by electrical pulses that start from the sinus node, also called the sinoatrial node (SA node), located in the tissue of your right atrium.
The pulses then travel through your heart to the atrioventricular node, also called the AV node, located near the center of the heart between the atria and the ventricles. These electrical impulses keep your blood flowing in proper rhythm.
