hematopoiesis. the formation and development of blood cells, usually taking place in the bone marrow. cyclic hematopoiesis of collies. see canine cyclic hematopoiesis.[hÄâ²mÉtÅpÅÂ·Äâ²sis, hemâ²-]. Etymology: Gk, haima + poiein, to make. the normal formation and development of blood cells in the bone marrow. In severe anemia and other hematologic disorders, cells may be produced in organs outside the marrow (extramedullary hematopoiesis).etal hematopoiesis. in embryogenesis migration of stem cells from the yolk sac blood islands sets up hematopoiesis in thymus, lymph nodes, liver and spleen. When fetal bone develops a marrow cavity hematopoiesis is similarly established.
It's called circuit training. While this style of training has a lot to recommend it, figuring out how to set up an effective circuit workout can be intimidating at first. That's why we pulled together six easy steps to help you build your perfect circuit. Step 1: Select your time limit. Circuit training is simply a workout based around a set number of stations that you repeat until your time runs out. So knowing how much time you have can help you determine how many circuits you'll need to complete and how hard you'll need to work.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow.Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.ircuit breakers are manufactured in standard sizes, using a system of preferred numbers to cover a range of ratings. Miniature circuit breakers have a fixed trip setting; changing the operating current value requires changing the whole circuit breaker.
