The human heart is a vital organ that pumps blood throughout the body. It is about the size of a fist and is located in the chest, slightly to the left of the center. The heart is made up of four chambers: the right atrium, the right ventricle, the left atrium, and the left ventricle. Blood enters the heart through the right atrium and is then pumped into the right ventricle, which pumps it to the lungs. The lungs oxygenate the blood, and it then returns to the heart through the left atrium. The left ventricle then pumps the oxygenated blood to the rest of the body. The heart beats an average of 70 times per minute, and it pumps approximately 5 liters of blood per minute.

The human heart, a fist-sized organ located in the chest, is responsible for pumping blood throughout the body. It comprises four chambers - the right and left atria, and right and left ventricles. Blood enters through the right atrium, gets pumped to the lungs for oxygenation, and then returns to the left atrium before being pumped to the rest of the body by the left ventricle. This process happens at an average rate of 70 beats per minute, pumping approximately 5 liters of blood per minute.

Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Source text:
Elizabeth was born on 21 April 1926, the first child of Prince Albert, Duke of York (later King George VI), and his wife, Elizabeth, Duchess of York (later Queen Elizabeth The Queen Mother). Her father was the second son of King George V and Queen Mary, and her mother was the youngest daughter of Scottish aristocrat Claude Bowes-Lyon, 14th Earl of Strathmore and Kinghorne. She was delivered at 02:40 (GMT)[1] by Caesarean section at her maternal grandfather's London home, 17 Bruton Street in Mayfair.[2] The Anglican Archbishop of York, Cosmo Gordon Lang, baptised her in the private chapel of Buckingham Palace on 29 May,[3][b] and she was named Elizabeth after her mother; Alexandra after her paternal great-grandmother, who had died six months earlier; and Mary after her paternal grandmother.[5] She was called "Lilibet" by her close family,[6] based on what she called herself at first.[7] She was cherished by her grandfather George V, whom she affectionately called "Grandpa England",[8] and her regular visits during his serious illness in 1929 were credited in the popular press and by later biographers with raising his spirits and aiding his recovery.[9]

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.
