ফাজরের নামাজের পর আম্মুর ফোন, কুশল বিনিময় অতঃপরঃ - মা তোমার শরীর কেমন? ঐ ওষুধে কি কাজ হলো একটু? - হ্যা বাবা, আল্লাহ কী না পারেন! সেদিন থেকে একটু ভালো লাগছে, ফাজরের আগে ওঠারও শক্তি দিয়েছেন আল্লাহ, সুস্থতা যে কী নিআমত! আসলে ওষুধের তো ক্ষমতা নাই, ক্ষমতা তো আল্লাহর। তোমরা টেনশান করোনা। - অবশ্যই, আল্লাহই সব করেন। আলহামদুলিল্লাহ :) - সেদিন একটা আয়াতের ব্যাখ্যা পড়ছিলামঃ أَفَلَا يَنظُرُونَ إِلَى الْإِبِلِ كَيْفَ خُلِقَتْ তারা কি ঊটের দিকে লক্ষ্য করেনা, কীভাবে তাকে সৃষ্টি করা হয়েছে?.......। সূরা গাশিয়াহ এর এই ১৭ নং আয়াতের ব্যাখ্যাটা আমাকে ভাবিয়ে তুলল। ফোনালাপ শেষে গুগল থেকে মোটামুটি সাড়ে ৩ ঘণ্টার মত Camel Anatomy নিয়ে স্টাডি করলাম। সুবহানাল্লাহ! মরুর বুকে বেঁচে থাকার জন্য এত জটিল এবং অসাধারণ স্ট্রাকচার দিয়ে উটকে সৃষ্টি করা হয়েছে, পড়ছিলাম আর অবাক হচ্ছিলাম, সত্যিই আল্লাহর বড়ত্ব অনুভব করার জন্য যেকোন একটা সৃষ্টি নিয়ে চিন্তা করাই যথেষ্ট। বাংলায় অনুবাদ করে লিখলে ভালো হত, কিন্তু সেই সময় কিংবা ধৈর্য পাচ্ছিনা। ইংলিশটার জিস্ট ই শেয়ার করছি। [অনেকগুলো সাইট থেকে+ নিজের এনাটমি নলেজ মিলিয়ে লেখা, কেউ চাইলে বাংলায় অনুবাদ করে নোট আকারে লিখতে পারেন।] Amazing Body Structure of Camel: 1. The Hump: The hump of the camel is the storage of fats. It provides nutrient to the animal periodically in times of starvation(by gluconeogenesis). With this system, this animal can live for 3 weeks without water, whilst it looses 33% of its weight. Under the same circumstances, a human being would lose 8% of his weight and die within 36 hours, completely loosing the water in his body. 2. The Eyes: Unlike human, camel has the extra eyelid called Third Eyelid (anatomically nictitating membrane). It is a thin, clear sheath that can open and close behind the outer eyelids, which protects them from the blowing sands of their native habitat while allowing enough light to see where they are going, almost like a pair of built-in sunglasses. It opens and close horizontally, just like a sliding glass door. (See here how it acts: en.wikipedia.org/wiki/Nictitating_membrane) 3. The Nose: - Camels can open and close their muscular nostrils at will, which prevents them from inhaling sand in the event of a sandstorm. - Also camel nose has another special quality of conserving water. Measurements suggest that camels have more than 1000 cm2 of nasal surface area, whereas the human nasal cavity may have a total surface area of only 160-180 cm2. Normally, the surface of the turbinates is covered with moist secretions, which help humidify dry desert air as the camel breathes in and remove water vapor as the camel breathes out. However, as the camel becomes dehydrated and the nasal passages dry out, this simple mechanism works in reverse: the nasal surfaces give off water during inhalation and take up water as air is exhaled. (See how scientists have used this process in Water Desalinization project: discoveryofdesign/id129.html) 4. The Feet: - A camel’s feet are actually not hooves, but each toe does have a hard nail that gives the impression of a hoof. The wide, spreading toes keep the camel from sinking into loose and shifting sands, the thick sole also provides a barrier against the hot desert sands, protecting the camel from being burned. When a camel walks, it moves both legs on one side and the both legs on the other, rocking side-to-side. This is why camels are nicknamed The ships of the desert. - Camel legs are incredibly strong, which allows them to carry up to 1000 pounds. They also can walk 100 miles per day and sprint at 12 miles per hour. 5. The Body Heat: - Camels possess an excellent thermoregulating mechanism. When the outside temperature is higher than body temperature, most mammals sweat to cool off, but not the camel. Unlike most mammals, a healthy camels body temperature fluctuate throughout the day from 34°C to 41.7°C (93°F-107°F.) This allows the camel to conserve water by not sweating as the environmental temperature rises. Camels are the only mammals that can withstand a loss of 25% of body weight due to sweating, while others do not survive after 3-4%. - Camels body fur consists of thick and matted hairs that do not only protect the body of the animal against freezing and burning weather conditions, but also eliminate the water loss of the body. With its thick fur, camels in Asia can survive high temperatures rising up to +50C in summer and falling down to -50C in winter. 6. Water Reserve Process: - Camels can consume up to 130 liters of water almost in 10 minutes which is around one third of their body weight. Their red blood cells have an oval shape, unlike those of other mammals which are circular which facilitate their flow in a dehydrated state. These cells are also more stable, in order to withstand high osmotic variation without rupturing, when drinking large amounts of water in one drink. - The kidneys of a camel are very efficient. Urine comes out as a thick syrup and their feces are so dry that they can fuel fires. - Also their large nasal surface area, temperature fluctuating mechanism, thick fur coat prevents loss of water through sweating. Such a physiological process helps it endure in the desert for at least 3 weeks without water. 7. The Milk: Camel milk, the Bedouin beverage of choice, is more nutritious than cow milk, with more potassium, more iron, and three times as much vitamin C. In fact, Camel milk will soon become available in grocery stores across Europe. In the meantime, candy makers from Vienna are developing a chocolate camel milk for the kids. সবকথার শেষে এইটুকু বলতেই হয়ঃ أَفَلَا يَتَدَبَّرُونَ الْقُرْآنَ أَمْ عَلَىٰ قُلُوبٍ أَقْفَالُهَا তারা কি ক্বুরআন সম্পর্কে গভীরভাবে চিন্তা করে না? না তাদের অন্তর তালাবদ্ধ? [সূরা মুহাম্মাদঃ আয়াত ২৪]
