The nervous system.
In the last two modules of BIO2101, we learned about the nervous system. In this module, we explored how the cardiovascular system assists in the transport of hormones produced by the endocrine system, in addition to getting glimpses of how other organ systems may have overlap with one or both systems.
This assignment will address the challenge put forward by Jake: How do the nervous and endocrine systems affect the cardiovascular system in similar or different ways?
Instructions
Imagine if you were walking along the beach and cut the bottom of your foot open from a sharp piece of beach debris. Prepare a written paper of at least 1000 words that includes the following:
Discuss components of blood that participate in wound healing and discuss their roles in the wound healing process.
Using specific examples, compare the process by which a hormone and a neurotransmitter will be secreted in response to this accident.
Examine the action of a neurotransmitter compared to that of a hormone on the physiology of the heart and blood vessels as a result of sustaining this injury.
Sample Solution
Most of us take wound healing for granted. The wound-healing process consists of four highly integrated and overlapping phases: hemostasis, inflammation, proliferation, and tissue remodeling or resolution (Gosain and DiPietro, 2004). Stopping the bleeding (hemostasis) – when your skin is cut, scraped, or punctured, you usually start to bleed. Within minutes or even seconds, blood cells start to clump together and clot, protecting the wound and preventing further blood loss. These clots, which turn into scabs as they dry, are created by a type of blood cell called a platelet. The clot also contains a protein called fibrin, which forms a net to hold the clot in place.
