BT_PO 1.33 Discuss the difference between the pulmonary and systemic circulations

BT_PO 1.47 Discuss the control of blood pressure and the distribution of blood volume and flow throughout the cardiovascular system including:

· The factors determining systemic blood pressure and its regulation and control

· Total peripheral resistance and factors affecting it

· The relationship between organ blood flow and demand and the role of autoregulation

· Clinically significant features of the coronary, cerebral, skin, muscle, renal, hepatic and splanchnic circulations

· The essential features of the microcirculation including fluid exchange and its control

BT_RT 1.13 Describe the cerebral circulation, the regulation of cerebral blood flow and factors leading to the loss of autoregulation

BT_RT 1.15 Describe the blood supply to the spinal cord and the regulation of spinal cord blood flow

SS_OB 1.4 Describe the utero-placental circulation and the principles of placental physiology as related to placental gas exchange and regulation of placental blood flow

Past SAQs

2015.2, 2012.2, 2004.1 Briefly outline the differences between the pulmonary circulation and the systemic circulation

2008.1 The skin, the kidneys, and the carotid bodies are examples of where specific organ blood flow is far in excess of that organ's metabolic requirements. For each example, explain what the physiological role of the high organ blood flow is, why this high flow is an advantage to the person and a brief description of the mechanisms involved.

2004.2, 2001.2 Explain the physiological processes involved in the development of interstitial oedema

2002.2 Outline the factors that determine coronary vascular resistance.

2000.1 What is a normal pulmonary vascular resistance. Outline physiological factors that influence pulmonary resistance.
