There are several major differences between the nervous system, and the endocrine system. First, the most dramatic difference is that the nervous system works very quickly, in less than a second it can accomplish its task of sending electrical impulses to an organ for response. While the endocrine system 's task of sending hormones to receptors can take much longer sometimes more than a day. Another note of temporal difference, is that the nervous system 's response lasts a short time, but the endocrine 's system response can last a long time. Lastly, as noted in the temporal differences, the nervous system sends electrical impulses to the organs to get them to react, and the nervous system sends hormones to get the organs to react. As a result, these two systems work together with the nervous system sending impulses and the endocrine system triggering hormones, causing a reaction on organs for …show more content…
Anastomoses could also be described as a traffic circle or rotary, where there are other paths for the blood to flow since several arteries come together at different parts of the body. Alternative pathways that anastomoses provide are crucial if there is an obstruction in a pathway or a severed artery, giving more choices for the blood to go through. The presence of anastomoses can be found in the heart, brain (specifically the cerebral arterial circle), and abdominal organs. There are three different types of vascular anastomoses, which include: arterial ( where several arteries meet), arteriovenous ( where several arterioles and venules meet), and venous (where several veins meet). The amazing connections of anastomoses creates a super highway for blood to flow in the human
