WebThere waste gases are given off to the environment, and oxygen is absorbed. The oxygenated blood enters efferent (exuant) arteries of the gill arches and then flows into the dorsal aorta. From there blood is distributed to the tissues and organs of the body. One-way valves prevent backflow. Webreceptors (D 1 R and D 5 R) and D 2-like receptors (D 2 R, D 3 R, and D 4 R).1–3 There is abundant evidence that an intact dopaminergic system is necessary to maintain normal blood pressure and that genetic hypertension is associated with alterations in dopamine production and receptor function.1–4 In humans and rodents, some dopamine ...
