\nPlatelets, or thrombocytes, are small, irregular-shaped cell fragments found in blood. Their main function is to stop bleeding (hemostasis) by clumping together to form a plug at the site of injury and by releasing factors that promote blood clotting. In viral infections like dengue fever, a decrease in platelet count (thrombocytopenia) is common and can lead to increased risk of bleeding, highlighting their essential role in blood clotting.

\n– Platelets are involved in hemostasis (stopping bleeding).
\n– Platelets facilitate blood clotting.
\n– Low platelet count (thrombocytopenia) increases bleeding risk.
\n<\/section>\n
\nRed blood cells are responsible for oxygen transport. White blood cells are part of the immune system. Plasma carries dissolved substances like nutrients, hormones, and waste products throughout the body. Carbon dioxide is transported in blood primarily as bicarbonate ions, bound to hemoglobin, or dissolved in plasma. Platelets are specifically critical for initiating and supporting the coagulation cascade, forming a blood clot.
