The movement of blood between the heart and all other parts of the body beside the lungs is

Step 1: Analyze the question The question asks for the name of the blood movement between the heart and every part of the body except the lungs.

Step 2: Explain the concept In humans (mammals), blood travels in two circuits, which is why we have a double circulatory system:

• Pulmonary circulation: Heart → lungs → heart. The right ventricle pumps deoxygenated blood through the pulmonary artery to the lungs. Oxygenated blood returns through the pulmonary veins to the left atrium.
• Systemic circulation: Heart → rest of the body → heart. The left ventricle pumps oxygenated blood through the aorta to all body tissues. Deoxygenated blood returns through the vena cava to the right atrium.

Step 3: Evaluate the options

• A. Double circulatory system: This covers both circuits together, including the lungs, so it is too broad.
• B. Pulmonary system: This is the heart-to-lungs circuit, which is exactly what the question excludes.
• C. Single circulation: Blood passes through the heart once per complete circuit, as in fish. This does not fit.
• D. Systemic circulation: This is the movement of blood between the heart and all body parts other than the lungs. It matches the question.

Step 4: Answer The correct option is **D.

Exam tip: Think "System = the whole body system" and "Pulmo = lungs". When a question says "other than the lungs", the answer is systemic. When it says "both lungs and body", the answer is double circulation.
