Review the elements of the skin system to prepare for the MCAT exam. Video lessons and quizzes incorporate all of the elements of the skin system section in a simple and clear manner.

Skin System - Chapter Summary

When you begin this chapter, you will learn about the function, layers and structure of human skin. Over the course of the 'Skin System' chapter, you will also encounter the following concepts:

  • Function and structure of epithelial tissue
  • Physical protection by skin
  • Skin function in thermoregulation, osmoregulation and homeostasis

We present these concepts by delivering easy-to-digest, short video lessons and supplementary quizzes. Our quizzes provide you with immediate feedback to help you understand your areas of strength and weakness. You can also use your quiz results to help you determine if you're ready to answer the skin system questions that are featured on the MCAT's biological sciences section.

Skin System Objectives

As determined by the MCAT's skin system test objectives, you must be familiar with topics that include:

  • Hair, nails and calluses
  • Sweat glands
  • Vasodilation and vasoconstriction in surface capillaries
  • Cell and tissue types
  • Layer differentiation
  • Erectile musculature
  • Insulation through fat

Other than the biological sciences section, the MCAT features verbal reasoning and physical sciences sections. You can also choose to sit for an optional trial section. On the biological sciences section, you must complete 52 multiple-choice questions within 70 minutes. During this section, you need to answer question sets related to seven reading passages and 13 individual questions. There are about four to seven questions assigned to each reading passage.
