In this patient the serosal cavity that was penetrated by the first arrow was the peritoneal cavity. The location of the patients injury is between the 7th and 8th ribs, this could penetrate the lungs and possibly the heart. The purpose of the serous membrane is to provide a lining to the organs of the body. The patients Autonomic Nervous System will send various signals to the sensory neurons and cause the Peripheral Nervous System to send back neural signals to the dermis and epidermis in the form of pain. When it comes to the patients vital signs, such as their Temperature, Respirations, Pulse, and Blood Pressure, these will all change from a level of homeostasis to more unstable levels. For example when it comes to body temperature, after sustaining an injury such as this one, the body temperature will drop due to lack of respirations and breathing patterns. A lack in breathing results in a lack of oxygen reaching the tissues of the body, thus causing the body temperature to drop. When it comes to the patients respiration, this will also decrease. This is due to the fact that the location of the arrow penetrates the thoracic muscles, which help with respirations. Lack of respiratory muscles, will cause the patients respirations to decrease. When it comes to the patients pulse, this will increase. The reason that the heart rate will increase, is because the sensory neurons are sending information to the brain telling it that the open wound needs more blood. Since the body is losing blood, the heart will try to work faster to pump more blood to the areas that are affected. The blood pressure of this patient will decrease because the blood will now lack oxygen, due to the fact that the injuries this patient has sustained has decreased his respirations, therefore decreasing the amount of oxygen in the blood.
The first angle entered the patient at a sagittal plane through the upper left quadrant of the thoracic cavity, puncturing his lung and possibly heart.
The cardiovascular system has two different paths. The pulmonary circulation and the systemic circulation. They work together to get blood throughout the entire body to properly oxygenate the organ systems. The hematocrit levels in the patient will likely decline, this is because hematocrit measures the amount of blood volume compared to the total blood volume in the body. Sustaining such an injury will result in loss of blood, causing hematocrit levels to drop. Hemoglobin levels will also drop due to the fact that the respiratory system is no longer oxygenating the blood cells.
One neuromuscular effect of the second arrow could be muscle paralysis. This is due to the fact that in this area of the body, the posterior clavicle triangle holds the muscles used to control head and neck movement. Sustaining an injury to these will cause lack of muscle contractions. At the neuromuscular junction, the ACH and ACH receptors will not be able to come together to cause muscle contractions because the axoplasm and neurilemma, along with the axon and muscle fibers, will all be damage from the arrow that pierced the patient.
Number 1 muscle tissue. Number 2 is osseous tissue, and number 3 is connective tissue. These areas will begin to produce more cells to try and maintain themselves during the bodys crisis injury period.
