Cell organelles have specialized functions within cells. The nucleus contains DNA and controls the cell, the endoplasmic reticulum transports proteins and detoxifies toxins, and mitochondria produce energy through respiration. Other organelles like chloroplasts, lysosomes, vacuoles, and the cell membrane have important roles in photosynthesis, digestion, storage, and boundary definition.
Most relevant information about the cell, its discovery, types and various kinds of organelles and their function. it also focus on how molecules are transported across the cell membrane.

Coagulation: In medicine, the clotting of blood. The process by which the blood clots to form solid masses, or clots.
More than 30 types of cells and substances in blood affect clotting. The process is initiated by blood platelets. Platelets produce a substance that combines with calcium ions in the blood to form thromboplastin, which in turn converts the protein prothrombin into thrombin in a complex series of reactions. Thrombin, a proteolytic enzyme, converts fibrinogen, a protein substance, into fibrin, an insoluble protein that forms an intricate network of minute threadlike structures called fibrils and causes the blood plasma to gel. The blood cells and plasma are enmeshed in the network of fibrils to form the clot.
