3rd Qtr. 1st week

Endocrine System:

What I learn from this body system is that its works together with the nervous system to regulate the activities of all the body system. It secretes hormones that act on cells by binding to external receptors, causing changes in enzyme activity inside the target cell. Hormone levels can be regulated by 3 mechanism:
  1. Neural Control
  2. Hormonal Control
  3. Humoral Control
