The mouth, stomach, small intestine, and large intestine are organs that work together to perform the specific function of food digestion and absorption in organisms. Which of the following describes the level of biological organization described above?

• cell

• organelle

• organ system

• organ

You accidentally place your hand on a hot stove. The nerve cells in your hand respond to the pain, the stimulus, resulting from the heat. The nerve cells would relay this information to which of the following?

• stimulus

• effector

• receptor

• control center

When a muscle cell is stimulated, calcium is released into the muscle fiber. This calcium binds to proteins that start the muscle contraction process. The initial release of calcium triggers more calcium release, which amplifies the contraction. This feedback loop continues until the muscle contraction is fully achieved. Which of the following best describes the scenario above?

• metabolism

• adaptation

• positive feedback loop

• negative feedback loop

Before eating an orange, you separate it into an upper and lower half. Which of the following is the plane on which you cut the orange?

• ventral plane

• frontal plane

• transverse plane

• sagittal plane

A specific type of MRI, or magnetic resonance imaging, looks at the brain in 24 vertical sections, starting from the right side of the brain and moving to the left side of the brain.

Which of the following planes of symmetry would split the human brain into left and right vertical sections?

• saggital

• spinal

• transverse

• coronal

Identify two different body cavities and the planes of symmetry they would be found in. Why is it important to understand how body cavities interact with planes of symmetry for medical practices such as imaging and surgery?
