Answer: External intercoastal muscles increase the size of thorasic cavity during inhalation.

Inhalation is the process of breathing in oxygen.

During inhalation, diaphragm contracts and it lead to the expansion of lung volume. When diaphragm contracts, it moves to the abdominal cavity which create a large thorasic cavity . when the external intercoastal muscles contracts, it cause toward and downward movement of the ribs, which cause the rib cage to expand , thereby leading to increase in size of thorasic cavity.

Answer: An essay is a common type of academic writing that you'll likely be asked to do in multiple classes. Before you start writing your essay, make sure you understand the details of the assignment so that you know how to approach the essay and what your focus should be. Once you've chosen a topic, do some research and narrow down the main argument(s) you'd like to make. From there, you'll need to write an outline and flesh out your essay, which should consist of an introduction, body, and conclusion. After your essay is drafted, spend some time revising it to ensure your writing is as strong as possible.
