Transcript of Skeletal System Homeostasis

The Skeletal System: Homeostasis By: Elizabeth Paulson and Marina Tretton Sickle Cell Skeletal System Organs Stem Cells Hematopoiesis Homeostasis What is Homeostasis? It is the body's tendency toward a relatively stable equilibrium between interdependent elements. Sickled cells alter cell volume The Hematopoietic mechanism reacts with positive feedback Production stays extreme until levels are regular Divides bone marrow into either:
Red Blood Cells: Transports oxygen throughout the body.
White Blood Cells: Makes up the body's immune system. In Conclusion: Positive and Negative Feedback Positive Feedback: The body trying to fix the problem.

Negative Feedback: The body trying to get back to normal. Thanks for listening! Axial-
