Pulmonary arterioles respond to different factors than systemic arterioles because in the lungs, the blood supply is receiving oxygen and delivering carbon dioxide, while in the systemic circulation, it is delivering oxygen, and receiving carbon dioxide. In the pulmonary circuit, arterioles will dilate in well-ventilated areas of the lungs to increase the rate of exchange between capillaries and well-ventilated alveoli. However, in poorly ventilated areas of the lungs, arterioles will constrict in order to re-route blood to well-ventilated areas. Now consider our case of pulmonary oedema, and how that will impact circulation in the pulmonary circuit. (Select two answers). O Pulmonary arterioles will dilate O Pulmonary arterioles will constrict O Pulmonary vascular resistance will increase O Pulmonary vascular resistance will decrease

Dissection

Dissection is the process of cutting up the tissue of a dead or live animal or plant, to do anatomical studies and surgical treatments. The purpose of dissection is to learn more about the overall structure of organs and organ systems and thereby understand the physiology of the organism.
