through the lymph vessels is quite slow. The lymphatics resemble the veins in their structure having; 1)An outer coat of fibrous tissue 2)A middle coat of muscular elastic tissue 3)An inner lining made up a single layer of epithelial cells Also like the blood in the veins‚ contraction of skeletal muscles compresses the lymph vessels and squeezes the plasma fluid- now called lymph- along. Again like return of the blood in the veins‚ the lymph can flow only in one

The liver is also attached to the lesser curvature of the stomach by the hepatogastric and to the duodenum by the hepatoduodenal ligament (see page 1157). 17 The falciform ligament (ligamentum falciforme hepatis) is a broad and thin antero-posterior

Introduction Cirrhosis is a progressive chronic inflammation of the liver that typically results from severe chronic hepatitis or chronic alcoholism as we know. Cirrhosis is defined histologically as a diffuse hepatic process characterized by fibrosis and the conversion of normal liver architecture into structurally abnormal nodules. In other words‚ The damaged hepatocytes regenerates‚ but the liver’s connective (scar) tissue regenerates faster. As a result‚ the liver becomes fatty and fibrous

Coronary Vein. Deoxygenated blood containing carbon dioxide and waste products is returned from the heart muscle to the right atrium through this vessel. Pulmonary Veins. The four pulmonary veins‚ two from each lung‚ carry oxygenated blood from the lungs to the left atrium. Hepatic Portal Vein. The hepatic

1. External morphology of exopterygota: The Exopterygota are all hemimetabolous insects that have wings which develop externally and do not undergo a significant metamorphosis via a pupal stage. Apart from being wingless and smaller‚ the nymphs (immature stages) of these species are generally quite similar in appearance to the adults. Endopterygota Holometabolous insects undergo significant morphological changes during their development. The larvae (mostly grub-like)

bone marrow. They help in the clotting process. These blood cells are carried through blood vessels in liquid called plasma. There are three types of blood vessels: arteries‚ veins and capillaries. Arteries carry blood away from the heart while veins carry blood to the heart. Capillaries connect arteries to veins. The right and left halves of the heart act as separate pumps and there is no mix of blood between them. Each half is responsible for pumping blood through one of two blood vessel

Unit 4 Report Distributing Metabolites through the body Food that we consume is composed of very complex molecules. During the digestive process these compounds are broken down into smaller and smaller subunits in preparation for use by the body as building blocks needed for the many components of the human body. In Module 3 we followed the food through the digestive system and considered the process that takes place in the digestive system. The pizza that was eaten by Matt and Maria contained ingredients
