Presentation about The Blood Type Diet

Ketoacidosis

What is Ketoacidosis? its very important to know ketoacidosis when you study about blood histology and physiology.

Ketoacidosis is phase decompensation advanced type 1 diabetes leading to acidification of blood and the presence of derivatives of acetone in blood and urine. It causes fatigue, nausea, difficulty breathing and, without treatment coma.

blood in vertabrates and invertabrates

•In vertebrates, the circulating fluid, or blood is kept within a closed circulating system, whereas hemolymph is the circulating fluid of animals with open circulatory system, for example insect.
•The coelomic fluid of some invertebrates also has a circulatorry role instead of blood.
•The function of blood.
•Respiratory pigments in blood.
•Transport of nutrients
•Circulate hormones
•Blood clotting
•İmmune reponses
•Phagocytosis of dead cells and foreign materials
•İmportant pH buffer system
•Constituents of blood can confer antifreeze properties.
•Heat exchange
•Blood volume is 6% in cephalopod mollusks, 3-16% in vertebrates, and 30% or more in arthropods.
•In animals having open circulatory system, the blood volume is only a fraction of the extracellular fluid volume but blood volume is only a fraction of the extracellular volume for animals with a closed circulatory system.
•Hematocrit value
Plasma volume, cell volume

Blood Platelets

Platelets, or thrombocytes, the smallest formed elements in the blood histology , are disklike cell fragments that vary in diameter from 2 to 5 um. In humans, they lack nuclei and originate by budding from large cells in the bone marrow called megakaryocytes. They range in number from 200,000 to 400,000 mm3 of blood and have a lifespan of about 8 days. In blood smears they appear in clumps. Each platelet has a peripheral hyalomere region that stains a faint blue and a dense central granulomere that contains a few mitochondria and glycogen granules and a variety of purple granules. Platelets have an important physical role in plugging wounds, and they contribute to the cascade of molecular interactions among the various clotting factors dissolved in the plasma blood histology
