Terminologia Anatomica
What could be the cause of Sean's breathing problems?
The excess mucus also blocks passages in the respiratory system, which leads to problems with breathing.
Which four organ systems might be the most severely affected by the victim's injuries?
The four organ systems that would most likely be affected are the integumentary, muscular, digestive, and cardiovascular systems.
How are the victim's injuries affecting his ability to maintain homeostasis and what are the actions taken by the EMTs to combat that disruption?
The massive blood loss is going to have consequences on the ability to maintain adequate blood pressure and body fluid volume. The EMTs are administering IV fluids and trying to slow the bleeding by applying pressure.
