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.
1) In electronics, a circuit is a path between two or more points along which an electrical current can be carried. (A circuit breaker is a device that interrupts the path when necessary to protect other devices attached to the circuit - for example, in case of a power surge.) 2) In telecommunications, a circuit is a discrete (specific) path between two or more points along which signals can be carried. Unless otherwise qualified, a circuit is a physical path, consisting of one or more wires (or wireless paths) and possibly intermediate switching points.
