What does the portal vein drain? It drains blood from the pancreas, spleen and digestive organs and delivers it to the liver. 18. What is the function of the dorsalis pedis artery? It functions to carry oxygenated blood from the dorsal surface of the foot.
2. Locate each of the following lymphatic vessels. a. Right Lymphatic Duct b. Thoracic (left lymphatic) Duct c. Right and Left Subclavian Veins d. Cisterna Chyli . e. Determine the direction of blood and lymph movement between arterioles, blood and lymph capillaries, and venules.
This paper aims to describe the pathophysiology of atrial fibrillation and the rationale behind the information included in the patient education tool. Atrial Fibrillation: A Patient Education Guide The heart is a muscle that contains four chambers; the right atrium, left atrium, right ventricle, and left ventricle. Each of these chambers has a purpose. The right ventricle pumps blood to the lungs and the left ventricle pumps blood to the rest of the body. The right atrium receives deoxygenated blood via the superior and inferior vena cava.
Year 10 Pre-Diploma Biology Heart Dissection Introduction This lab practical allows you to identify and compare the size, shape and tissue type of the major chambers and vessels of the heart. The goal of the lab is not just to observe anatomy, but to associate structure with function. The heart is a pump for blood that comes into the right atrium, goes out to the lungs through the right ventricle, returns through the left atrium, and leaves again through the left ventricle - a double circulation. Each chamber is separated by valves that prevent the backflow of blood. Try and figure out where the various components are, how each works, especially how the shape, composition, and even texture of each part contribute to its function.

The wave passes to the atrioventricular node where it is passed down the septum down specialised fibres known as the bundle of His. This occurs after a short delay to allow all the blood to flow from the atria to the ventricles. This wave passes down the bundle of His to the Apex of the heart where the Ventricles contract upward, pumping blood out of the ventricles into the pulmonary artery and aorta through the semilunar valves. Here the blood is then passed round the body where it
Blood flows past the aortic semilunar valve when the contracts. A. left atrium B. right atrium C. left ventricle D. right ventricle 5. Which is true? A. The left atrium contracts before the right atrium.
These vessels are generously spread throughout the entire body, present in nearly every tissue of the body. These vessels, similar to the circulatory vessels, are composed of smaller lymphatic capillaries that converge to form collecting vessels. These vessels then merge even further to form what is known as a lymphatic trunks, which give rise to the lymphatic ducts. There are two major lymphatic ducts in the body; the right lymphatic duct, which drains the right arm and right side of the trunk, head and neck, and the thoracic duct, which drains the remaining portions of the
Air enters the respiratory system through the nostrils and mouth (External nares) Then the air goes through the larynx and trachea, which is a tube that enters the chest cavity. Then the trachea splits into two tubes, bronchi, which split further into bronchial tubes. Bronchial tubes lead further to the lungs, where they divide in many smaller tubes which connect to tiny sacs called alveoli. The trachea and surfactant perform there function of preparing the air to enter the lungs through cleaning the air and warming it up. (Essentials of Anatomy & Physiology, Chapter 15, 504-511) 2.
It forms from the joining of the two common iliac veins about the level of the umbilicus on the right side of the fifth lumbar vertebra. On its way up to the heart, inferior vena caca collects blood from kidneys and all the organs of the abdomen, penetrates the diaphragm and drains into the right atrium (Yahoo Health, 2012). The inferior vena cava carries de-oxygenated blood from the lower part of the body to the right atrium of the heart. Blood from the right atrium then goes to the right ventricle via the tricuspid valve. From the right ventricle arises the pulmonary trunk which later divides in to the right and left pulmonary arteries.
