* Mixture: Blood is made up of different substances that are not chemically bonded together. These substances retain their individual properties.
* Compound: A compound is formed when two or more elements chemically combine in a fixed ratio.
Components of Blood:
Blood is a complex mixture that includes:
* Plasma: This is the liquid portion of blood, containing water, proteins, electrolytes, nutrients, and waste products.
* Red blood cells (erythrocytes): These cells carry oxygen throughout the body.
* White blood cells (leukocytes): These cells fight infection and disease.
* Platelets (thrombocytes): These cell fragments help with blood clotting.
Since these components are not chemically bonded, they can be separated by various methods like centrifugation. Therefore, blood is classified as a compound mixture.
