PPT-Systemic Circulation - Veins

Portal Circulation The hepatic portal system is designed to take nutrient rich venous blood from the digestive tract capillaries and transport it to the sinusoidal capillaries of the liver As it percolates through the liver sinusoids the hepatocytes of the liver acting as the chemical factories of the body extract and add what they wish to maintain homeostasis extracting sugars fats proteins when appropriate and then dumping them back into the circulation when necessary. 18 Anatomy . of blood vessels. Joe Pistack MS/ED. Circulatory system. Circulatory System consists of the heart and blood vessels.. The blood vessels are a series of connected, hollow tubes that begin and end in the heart.. Superior vena cava. . returns blood from body regions superior to the diaphragm. Inferior vena cava. . returns blood from body regions inferior to the diaphragm. Superior and inferior vena cava. join the right atrium. Heart – located in mediastinum within the thoracic cavity. The Pericardium – . membrane surrounding heart. Serous Pericardium . = 1.

Aorta: largest artery in the body, arises from the left ventricle of the heart. Parts of the aorta. Ascending aorta: leaves the heart. Aortic arch: arches toward the left side of the body.

THE PULMONARY AND SYSTEMIC CIRCULATION. .. THE PULMONARY CIRCULATION. CARRIES BLOOD BETWEEN THE HEART AND THE LUNGS.  THIS CIRCULATION BEGINS AT THE RIGHT VENTRICLE AND ENDS AT THE LEFT ATRIUM. 3. Oxygen-Poor blood is pumped out of the Right Ventricle of the Heart into the Lungs through the Pulmonary Arteries.  These are the only Arteries in the Body to Carry Deoxygenated Blood. . th.

The function of the circulation is to serve the needs of the body tissues—to transport nutrients to the body tissues, to transport waste products away, to transport hormones from one part of the body to another and, in general, to maintain an appropriate environment in all the tissue fluids of the body for survival and optimal function of the cells. The rate of blood flow through many tissues is . INTRODUCTION. The cardiovascular system is transport system of body. It comprises blood, heart and blood vessels. . The system supplies nutrients to and remove waste products from various tissue of body.. Blood Vessels and Circulation. Five types of blood vessels:. (. 1) . Arteries. . Two . large arteries . are the aorta . and . pulmonary trunk. (. 2) . Arterioles. (. 3) . Capillaries. (. 4) . Arteries. large diameter . contain large amount of elastic tissue >>>>>>> wind . kessel. effect. Arteries. contain less elastic tissue. contain much more smooth muscles. they are the major site of resistance. Differences from Systemic Circulation . Low peripheral Resistance . Low pressure . Systolic20-25 mm Hg, Diastolic 6 -12 mm Hg & Mean 15mm Hg. Pulmonary Arterioles Thin walled, large lumen . Pulmonary Capillaries shorter and wider and blood flow is pulsatile .
