A patient was brought to the Emergency Department by ambulance with two arrow wounds. One
arrow is still in the patient on the left side; entering anteriorly between the 7th and 8th ribs in a
15-degree angle, the arrow head protruding posteriorly. The second wound is located in the
posterior cervical triangle.

Question 1
What serosal cavities have been penetrated by the first arrow? Explain the location, the
microscopic cellular components of the serous membrane, and the purpose of the serous
membrane.
From the case details, the first arrow enters from the left side anteriorly between the 7th and 8th
ribs. The 7th and 8th ribs are part of the rib cage protecting the lungs and the heart, among other
vital organs. Penetrating between the 7th and the 8th ribs, the serosal cavity that the arrow passthrough is the left pleural cavity with the outer pleura attached to the chest wall (Singh, 2019). In
the human body, Singh (2019) note that the serous membrane lines the internal body cavities and
organs such as the heart, lungs, and abdominal cavity. The membrane is made up of thin
mesothelium composed of simple squamous epithelium (Martini, Tallitsch, & Nath, 2018). The
serous membrane is also made up of a high concentration of connective tissues, which is rich in
lymphatic and blood vessels (Singh, 2019). The primary function of the serous membrane is to
enclose body cavities and organs. Other than this, the serous membrane serves to reduce friction
during muscle movements.
