system is:

(4) Auricles > Artery > veins > ventricles.

Answer 2

Answer:

1) Auricles -> ventricles -> artery -> vein

Explanation:

Systemic circulation:

From the left auricle blood gets pumped into the left ventricle through the mitral or bicuspid valve and from the left ventricle it is pumped into the aorta (artery) which branches to various parts of the body and branch further into capillaries. It then joins back to form veins and bring back blood to the auricle of the heart. The inferior vena cave brings in blood from the lower part of the body whereas they superior vena cava brings in blood from the upper part of the body. The blood enters the right auricle.

Pulmonary circulation:

Deoxygenated blood from right auricle is pumped into the right ventricle through the tricuspid valve. From the right ventricle blood gets pumped into pulmonary artery which goes to the lungs. Blood receives o2 from the lungs and brings it back to the heart through the pulmonary veins which opens into the left auricle.

Important

• Arteries except pulmonary artery carry oxygenated blood.
• Veins except pulmonary veins carry Deoxygenated blood.
