  • Epigastric region includes the stomach, liver, pancreas, gallbladder, duodenum, adrenal glands, transverse colon, and spleen.

Negative Feedback Control Loop

  • A stimulus causes a change in a physiological value, such as blood sugar or body temperature.
  • A sensor, also called a receptor, detects the change.
  • A control center compares the value to the normal range.
  • An effector causes a change to reverse the situation and return the value to normal.

Homeostasis

  • Homeostasis is when the body is in balance.
  • When the body is out of homeostasis, it is considered unstable.
  • Ionic bonds are the strongest type of bond due to sharing opposite electrons.
  • Covalent bonds are the weakest type of bond because they share the same electron.
  • Sharing is caring in covalent bonds
