رت (blood) انسانن ۽ ٻين ڪرنگهيدار جانورن جي جسمن ۾ گردش ڪندڙ پاڻياٺو مادو هوندو آهي. ھي رت جي گردش جي سرشتي ۾ سڄي جسم ۾ ڦرندو رهندو آهي.


Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells.[1]

Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume),[2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes).[3] The most abundant cells are red blood cells.[4] These contain hemoglobin, which facilitates oxygen transport by reversibly binding to it, increasing its solubility.[5] Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood.

Blood is circulated around the body through blood vessels by the pumping action of the heart. In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from the tissues to the lungs to be exhaled. Blood is bright red when its hemoglobin is oxygenated and dark red when it is deoxygenated.[6][7]

Medical terms related to blood often begin with hemo-, hemato-, haemo- or haemato- from the Greek word αἷμα (haima) for "blood". In terms of anatomy and histology, blood is considered a specialized form of connective tissue,[8] given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen.[حوالو گهربل]

آنڱر مان رت وهندي

رت (blood) جاندارن جي جسم ۾ گردش ڪندڙ پاڻياٺو مادو هوندو آهي. ھي پاڻياٺ رت جي دوري جي سرشتي ۾ سڄي جسم ۾ ڦرندي رهندي آهي.

جانورن جا رت جي لحاظ کان ٻہ گروھ آهن. ٿڌي رت وارا جانور ۽ گرم رت وارا جانور.

انساني رت جا چار گروپ ٿيندا آهن.
