रक्त की सभी नलीयां किससे बना होता है​

Answer»

ANSWER:

लहू या रुधिर या खून एक शारीरिक तरल (द्रव) है जो लहू वाहिनियों के अन्दर विभिन्न अंगों में लगातार बहता रहता है। रक्त वाहिनियों में प्रवाहित होने वाला यह गाढ़ा, कुछ चिपचिपा, लाल रंग का द्रव्य, एक जीवित ऊतक है। यह प्लाज़मा और रक्त कणों से मिल कर बनता है। प्लाज़मा वह निर्जीव तरल माध्यम है जिसमें रक्त कण तैरते रहते हैं। प्लाज़मा के सहारे ही ये कण सारे शरीर में पहुंच पाते हैं और वह प्लाज़मा ही है जो आंतों से शोषित पोषक तत्वों को शरीर के विभिन्न भागों तक पहुंचाता है और पाचन क्रिया के बाद बने हानिकारक पदार्थों को उत्सर्जी अंगो तक ले जा कर उन्हें फिर साफ़ होने का मौका देता है। रक्तकण तीन प्रकार के होते हैं, लाल रक्त कणिका, श्वेत रक्त कणिका और प्लैटलैट्स। लाल रक्त कणिका श्वसन अंगों से आक्सीजन ले कर सारे शरीर में पहुंचाने का और कार्बन डाईआक्साईड को शरीर से श्वसन अंगों तक ले जाने का काम करता है। इनकी कमी से रक्ताल्पता (अनिमिया) का रोग हो जाता है। श्वैत रक्त कणिका हानीकारक तत्वों तथा बिमारी पैदा करने वाले जिवाणुओं से शरीर की रक्षा करते हैं। प्लेटलेट्स रक्त वाहिनियों की सुरक्षा तथा खून बनाने में सहायक होते हैं।

मनुष्य-शरीर में करीब पाँच लिटर लहू विद्यमान रहता है। लाल रक्त कणिका की आयु कुछ दिनों से लेकर १२० दिनों तक की होती है। इसके बाद इसकी कोशिकाएं तिल्ली में टूटती रहती हैं। परन्तु इसके साथ-साथ अस्थि मज्जा (बोन मैरो) में इसका उत्पादन भी होता रहता है। यह बनने और टूटने की क्रिया एक निश्चित अनुपात में होती रहती है, जिससे शरीर में खून की कमी नहीं हो पाती।

मनुष्यों में लहू ही सबसे आसानी से प्रत्यारोपित किया जा सकता है। एटीजंस से लहू को विभिन्न वर्गों में बांटा गया है और रक्तदान करते समय इसी का ध्यान रखा जाता है। महत्वपूर्ण एटीजंस को दो भागों में बांटा गया है। पहला ए, बी, ओ तथा दुसरा आर-एच व एच-आर। जिन लोगों का रक्त जिस एटीजंस वाला होता है उसे उसी एटीजंस वाला रक्त देते हैं। जिन पर कोई एटीजंस नहीं होता उनका ग्रुप "ओ" कहलाता है। जिनके रक्त कण पर आर-एच एटीजंस पाया जाता है वे आर-एच पाजिटिव और जिनपर नहीं पाया जाता वे आर-एच नेगेटिव कहलाते हैं। ओ-वर्ग वाले व्यक्ति को सर्वदाता तथा एबी वाले को सर्वग्राही कहा जाता है। परन्तु एबी रक्त वाले को एबी रक्त ही दिया जाता है। जहां स्वस्थ व्यक्ति का रक्त किसी की जान बचा सकता है, वहीं रोगी, अस्वस्थ व्यक्ति का खून किसी के लिये जानलेवा भी साबित हो सकता है। इसीलिए खून लेने-देने में बहुत सावधानी की आवश्यकता होती है। लहू का PH मान 7.4 होता है

Which literacy genre dominates 19th century English literature?? detailed answer​

Answer»

Answer:

In Britain, the 19th century is dominated by the Victorian era, characterized by Romanticism, with Romantic poets such as William Wordsworth, Lord Byron or Samuel Taylor Coleridge and GENRES such as the gothic novel. Charles Dickens, perhaps the most famous novelist in the history of English literature, was active during this time and contributed to the novel's emergence as the leading LITERARY genre of Victorian England.

In Germany, the Sturm und Drang period of the late 18th century merges into a Classicist and Romantic period, epitomized by the long era of Goethe's activity, covering the first third of the century. The conservative Biedermeier style conflicts with the radical Vormärz in the turbulent period SEPARATING the end of the Napoleonic wars from the Revolutions of 1848.

In Denmark, the early 19th century Golden Age produced prolific literary authors such as Søren Kierkegaard and HANS Christian Andersen.

In the later 19th century, Romanticism is countered by Realism and Naturalism. The late 19th century, known as the Belle Époque, with its Fin de siècle retrospectively appeared as a "golden age" of European culture, cut short by the outbreak of World WAR I in 1914.

  • The right atrium RECEIVES blood from the veins and pumps it to the right ventricle.

  • The right ventricle pumps the blood received from the right atrium to the lungs.

  • The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.

  • The left ventricle pumps the oxygenated blood throughout the body.

Give reasons.4. Plants need nitrogen to make proteins. Can they absorb nitrogen from the atmosphere?​

Answer»

Answer:Question 1. TIGER being a carnivorous animal doesn't feed on plants, instead feeds on plant eating ANIMALS, i.e., herbivorous animals or herbivores, such as a deer. The Brainliest Answer! Yes, the tiger doesn't eat plants but we can't say that it doesn't depends on plants.

Question 2. Yes. Autotrophic plants are those plants that prepare their own food by the process of photosynthesis. ... These plants are therefore known as heterotrophs and don't have the capability to do photosynthesis due to absence of chlorophyll.So,all plants are not autotrophic

Question 3.yes it is absolutely true , because in forest the trees continues to take nutrition from the soil , this lead to decrease in the nutrient in the soil and they will no farmer or anyone to be add fertilizers to the soil..

Question 4.No they can not absorb NITROGEN directly from the atmosphere but there is a BACTERIA called rhizobium in the roots of plants in soil which coverts nitrogen into nitrates. and these nitrates are then absorbed by plants
