In an open circulatory system, the cells are in direct contact with the cells in the organism. An example of this is the jellyfish. In a closed circulatory system, cells are not in direct contact with the environment.Take our own bodies for example. When we inhale oxygen fills our lungs and diffuses into our blood. When we exhale, we release waste, or carbon dioxide and other gases.

Investiga como se reproducen las células madres​
Damm [24]

Answer:

Las células madre son células que se reproducen constantemente y tienen la capacidad de transformarse en cualquier otro tipo de célula del cuerpo de un organismo. Una célula a partir de la cual pueden crecer todos los tejidos del cuerpo, o una gran parte de ellos, es obviamente una célula extremadamente útil.  

Si las células madre se guían en la formación de tejidos sanos y funcionales, entonces, potencialmente, la terapia celular podría aplicarse para muchas enfermedades. De hecho, si las células provienen del propio paciente, en teoría no habrá riesgo de su rechazo (como lamentablemente ocurre con los trasplantes).

Las células madre tienen la capacidad de reproducirse por sí mismas a través del proceso de mitosis celular, para crear copias idénticas (clones) de sí mismas..
