胃的黏膜每3-4天會再生一次,以保護其自身的酸性消化液,防止自我消化。它從不停止工作——它每天實際泵送約2,000加侖的血液。每個人的舌頭都有獨特的紋路和溝槽圖案,類似於指紋,儘管它不常用於身份識別。人體每分鐘會脫落約30,000-40,000個死皮細胞,這有助於形成家庭灰塵,並使皮膚每27-30天更新一次。牙齒琺瑯質一旦受損就無法再生,這與身體其他部位不同;牙本質可以修復輕微問題,但琺瑯質需要牙科干預。骨頭比鋼鐵每盎司更堅硬,但不是鑽石;它們能承受巨大的壓力,同時輕巧靈活。成年人平均約有60%是水,隨年齡和性別而異;這支持了體溫調節和營養運輸等功能。這是一個迷思;腦部掃描顯示我們隨著時間推移會使用大部分大腦,儘管不是同時使用,而是用於各種功能。中耳的鐙骨是最小的,約3毫米長,對於傳遞聲音振動至關重要。以每分鐘70次的速度,心臟在80年的壽命中跳動約25億次,不知疲倦地泵血。人眼透過對紅色、綠色和藍色波長敏感的錐狀細胞檢測約1000萬種顏色。人體約有3-4克鐵,主要在血液中,足以製造一根3英寸的釘子。小腸平均長20英尺,盤繞在腹部內,吸收大部分營養。膝蓋骨(髕骨)以軟骨形式形成,在2-6歲之間骨化,在出生時提供靈活性。肝臟可以從其質量的25%再生到完整大小,這是一種獨特的再生能力。味蕾數量為2,000-10,000個,每1-2週更新一次,能檢測甜、酸、鹹、苦和鮮味。指甲每月長約3毫米,比腳趾甲的1毫米快,受血流量影響。嗅覺記憶能夠回想起大約 50,000 種不同的氣味,與情感和生存相關。每隻腳有 26 塊骨頭,兩隻腳共有 52 塊,佔全身 206 塊骨頭中的一部分,支撐著身體的重量和運動。噴嚏以高達每小時 100 英里的速度排出空氣,以清除刺激物,並將飛沫散播到遠處。腸道微生物群擁有數萬億細菌,有助於消化、免疫甚至情緒。大腦由 60% 的脂肪組成,對於加速神經信號的髓鞘來說至關重要。眨眼可以滋潤眼睛並清除碎屑,每分鐘發生 15-20 次。琺瑯質含有96%的礦物質,比骨骼更堅硬,能保護牙齒免受磨損。血細胞會更新,但身體每天不會產生新的血液量;它會回收成分。耳垢(耵聹)會吸附灰塵和細菌,防止耳道感染。除了經典的五感之外,感官還包括平衡感、溫度感、疼痛感和本體感受。腎臟過濾血液以去除廢物,將200公升處理成1–2公升的尿液。頭皮毛髮每月生長約0.5英寸,每年平均總計6英寸。闌尾曾被認為無用,但它在疾病期間充當有益腸道細菌的儲存庫。微笑大約使用17塊肌肉,比皺眉(約43塊)少,這表明微笑更容易。角膜缺乏血管,直接從大氣中吸收氧氣。一生中,腺體大約產生一杯耳垢,它會自行清潔耳朵。大腿骨(股骨)是最長、最強壯的,支撐著體重。人類因代謝反應發出微弱的光,肉眼不可見,但可被敏感的相機偵測到。胃可擴張容納2-4公升,但在此之前會感到不適。喉部約使用20塊肌肉進行說話、吞嚥和呼吸。40-50%的說法是錯誤的;頭部散失的熱量與其表面積成正比,約為10%。作為心肌,心臟持續跳動而不會疲勞,與骨骼肌不同。體內所有DNA解開後將伸展約100億英里,足以往返太陽多次。You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
