成人の人体には206本の骨があります。これらの骨は構造を提供し、臓器を保護し、筋肉を固定し、カルシウムを貯蔵します。最も小さいもの(耳の中のあぶみ骨)から、最も大きいもの(太ももの大腿骨)まであります。皮膚は人体で最大の臓器です。平均的な成人で約20平方フィートの面積を覆っています。保護バリアとして機能し、体温を調節し、触覚、熱、寒さを感じさせます。高齢者を含む成人の平均安静時心拍数は、1分あたり60〜100回です。アスリートや非常に健康な状態にある人は、安静時心拍数が低い場合があります。その重量に基づいて最も強い筋肉は、咬筋(顎の筋肉)です。顎のすべての筋肉が連携して働くことで、臼歯に200ポンドもの力で歯を閉じることができます。人体の約60〜65%が水です。この割合は、年齢、性別、および全体的な健康状態によって異なる場合があります。水は、体温を調節し、身体機能を維持するために、体の細胞、臓器、組織において重要な役割を果たします。血液型O型陰性はユニバーサルドナーです。これは、O型陰性の血液を持つ人は、どの血液型にも輸血できることを意味します。ただし、O型陰性の血液型の人は、O型陰性の血液しか受け取ることができません。甲状腺は、体の代謝率、心臓および消化機能、筋肉制御、脳の発達、気分、骨の維持を調節するホルモンを生成します。人間の心臓には4つの部屋があります。上部の2つの部屋は心房、下部の2つの部屋は心室と呼ばれます。これらが連携して全身に血液を送り出します。肝臓は、人間の体内で解毒を担当する主要な臓器です。血流から毒素を処理して除去します。さらに、消化においても役割を果たし、脂肪の分解を助ける胆汁を生成します。健康な成人における平均的な体温は、通常98.6°F(37°C)です。ただし、正常な体温は、人、時間帯、天候によってわずかに異なる場合があります。人間の体には通常12対の肋骨があり、肋骨を構成しています。肋骨は、心臓や肺などの重要な臓器を保護するのに役立ちます。人体で最大の筋肉は大殿筋で、お尻にあります。主に体を直立させておく役割を担っており、ランニングやジャンプなどの活動においても重要な役割を果たします。腸、特に大腸は、人体で最も多くの細菌がいます。これらの有益な細菌は、消化、免疫機能、および全体的な健康において重要な役割を果たします。人体で最も小さい骨はあぶみ骨で、中耳にある3つの骨の1つです。あぶみ骨は、鼓膜から内耳への音波の伝導を助けます。人体で最も硬い物質は歯のエナメル質です。各歯の外層を覆う高度に鉱化された物質です。骨よりも強く、歯を虫歯から守ります。You scored 0 out of 15You scored 1 out of 15You scored 2 out of 15You scored 3 out of 15You scored 4 out of 15You scored 5 out of 15You scored 6 out of 15You scored 7 out of 15You scored 8 out of 15You scored 9 out of 15You scored 10 out of 15You scored 11 out of 15You scored 12 out of 15You scored 13 out of 15You scored 14 out of 15You scored 15 out of 15
