The movement of blood between the heart and all other parts of the body besides the lung is known as

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

Step 2: Explain the concept In mammals (including humans), blood flows in a double circulation, made up of two circuits:

• Pulmonary circulation: heart → lungs → heart. Deoxygenated blood goes to the lungs through the pulmonary artery, and oxygenated blood returns through the pulmonary vein.
• Systemic circulation: heart → all other body parts (head, limbs, organs) → heart. Oxygenated blood leaves through the aorta, and deoxygenated blood returns through the vena cava.

Step 3: Evaluate the options

• A. Systemic circulation: Correct. It covers blood flow between the heart and the whole body apart from the lungs.
• B. Closed circulatory system: This describes a type of system in which blood stays inside vessels. It does not name a specific route.
• C. Pulmonary circulation: This is heart to lungs only, which is the opposite of what the question asks.
• D. Single circulation system: This is found in fish, where blood passes through the heart once per full circuit. It is not a route to the body.

Step 4: Answer The correct answer is A. systemic circulation.

Exam tip: Remember "Pulmonary = Lungs" (both start with P and L-related terms) and "Systemic = System-wide", meaning the whole body. If a question says "besides the lungs" or "rest of the body", think systemic.
