sanguíneos

Sanguíneos is the plural form of the Spanish adjective sanguíneo, meaning related to blood or the circulatory system. The word derives from Latin sanguineus, from sanguis, sangre, and is used in biology and medicine to describe elements, processes, or characteristics associated with blood.

In biology and medicine, the term is commonly applied to the system sanguíneo, the circulatory system that mediates the transport of gases, nutrients, hormones, and wastes throughout the body. Its principal components include the heart, blood vessels, and blood itself. The system also supports immune defense, temperature regulation, and hemostasis, the process that stops bleeding after injury.

Blood is a composite tissue made up of cellular elements and plasma. The main cellular components are glóbulos rojos (eritrocitos), which carry oxygen; glóbulos blancos (leucocitos), which participate in immune responses; and plaquetas, which aid in clot formation. Plasma, the liquid fraction, contains water, proteins, electrolytes, hormones, and other soluble factors.

Blood vessels, or vasos sanguíneos, form the conduits of the system and include arteries, veins, and capilares. Arteries carry blood away from the heart, veins return it toward the heart, and capillaries facilitate exchange with tissues.

The color of blood is typically red in humans due to hemoglobina, but some organisms have blue or other hues due to different oxygen-carrying molecules, such as hemocianina in some invertebrates. Sanguíneos is thus a broad term used to describe anything pertaining to blood, its components, or its circulation.
