Provide a summary of this description of the human circulatory system: 

"The human circulatory system, also known as the cardiovascular system, is a complex network consisting of the heart, blood vessels, and blood. Its primary function is to transport nutrients, oxygen, hormones, and cellular waste products throughout the body. The heart, a muscular organ located in the chest, pumps blood through a system of arteries, veins, and capillaries. Arteries carry oxygen-rich blood from the heart to the body's tissues, while veins return oxygen-poor blood back to the heart. The blood flows through two primary circuits: the systemic circulation, which supplies blood to the entire body, and the pulmonary circulation, which exchanges carbon dioxide for oxygen in the lungs. The efficiency of the circulatory system is vital for maintaining homeostasis and supporting the overall health and function of the body's organs and tissues."

The human circulatory or cardiovascular system comprises the heart, blood vessels, and blood, functioning to transport oxygen, nutrients, hormones, and waste. The heart pumps blood through arteries (carrying oxygen-rich blood to the body) and veins (bringing oxygen-poor blood back to the heart). Blood circulates through systemic and pulmonary circuits—systemic supplying the body and pulmonary facilitating gas exchange in the lungs. This system is crucial for maintaining body function and health.

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: Give me a brief synopsis of what happened here:

"A YouTuber who deliberately crashed a plane to "gain notoriety and make money" has agreed to plead guilty to obstructing a federal investigation, the United States Department of Justice (DOJ) announced yesterday. In his plea agreement, California pilot Trevor Jacob admitted to "deliberately destroying" the plane wreckage and repeatedly lying to officials. The crimes of destruction and concealment with intent to impede a federal investigation carry a maximum sentence of 20 years imprisonment and a potential fine of up to $250,000. The Los Angeles district court may impose a lesser sentence due to the plea deal, though.

Jacob is scheduled to appear in court in the coming weeks, the DOJ reported. A DOJ public information officer, Ciaran McEvoy, told Ars that Jacob has not yet pleaded guilty. After an initial court appearance—essentially a bond hearing—a change of plea hearing will be scheduled. If Jacob pleads guilty at that hearing, a federal judge will schedule a sentencing hearing several months later. From there, Jacob would meet with the US Probation Office, which will draft a confidential pre-sentencing report recommending the sentence that the office thinks he deserves. Jacob and the prosecutors can either agree or disagree with that sentencing report, and then, ultimately, a judge will determine what sentence is imposed.  A former Olympic snowboarder and experienced pilot and skydiver, Jacob hatched his scheme to allegedly deliberately crash his plane on November 24, 2021, after securing a sponsorship and agreeing to promote a company's wallet in a video. The company has not been named, and there is no mention of wallets in the video titled "I Crashed My Airplane" that's still viewable on YouTube.

The real trouble for Jacob apparently started on November 26, 2021, when he reported the crash to the National Transportation Safety Board (NTSB), which informed him that "he was responsible for preserving the wreckage so the agency could examine it," the DOJ reported. Jacob told an NTSB investigator that he would "determine the crash location" and provide coordinates. The Federal Aviation Administration (FAA) launched its own investigation three days later, and according to the plea agreement, over the next few weeks, Jacob started lying to federal investigators rather than cooperating with the investigation."
Response: A YouTuber by the name of Trevor Jacob has confessed to intentionally crashing his plane for YouTube clicks. He faces up to 20 years in prison and a fine of $250,000. He had a sponsorship deal with a wallet company, although there is no mention of a wallet in the video. He tried to lie to the National Transportation Safety Board about the crash but was found out by the FAA during their investigation.

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.
