The cystic artery’s function is to supply passage of oxygenated blood to the gallbladder neck and the common bile duct. 16. What is the function of the portal vein? The portal vein carries blood that contains digested food from the small intestine to the liver. 17.
Through apolipoprotein C-II, the mature chylomicrons activate lipoprotein lipase (LPL). Lipoprotein lipase is an enzyme found on the endothelial cells that line the blood vessels, which catalyzes the hydrolysis of triacyglycerol (glycerol covalently bonded to three fatty acids). Triacyglycerol releases glycerol along with fatty acids found in the chylomicrons. Fatty acids and glycerol can be absorbed in muscle, peripheral tissues, and adipose, for energy as well as storage. The hydrolyzed chylomicrons become chylomicron remnants.
The lymphatic system is made up of lymphatic vessel and lymphatic organs. The lymphatic system has four main functions; lymphatic capillaries absorb excess tissue fluid and return it to the bloodstream. In the small intestines, lymphatic capillaries called lacteals absorb fats in the form of lipoproteins and transport them to the bloodstream. The lymphatic system also is responsible for the production, maintenance and distribution of lymphocytes. It also helps defend the body against pathogens.
QUESTION: Trace the route of the contrast medium from its site of injection to the urinary bladder for an intravenous urography examination. NAME OF CONTRAST MEDIUM: Uroselectan (42%) TYPE: An iodinated, ionic contrast media AMOUNT INJECTED: 0.2gram per kilogram of body weight SITE OF INJECTION: 1) Right Median Cubital Vein The site of injection for an intravenous urography (IVU) examination could be the right or left cubial vein. For this study, the right median cubital vein will be utilized. This vein is located to the anterior aspect of the right elbow and connects the right basilic and cephalic veins, which run along the medial and lateral aspects of the right forearm respectively. Once access to the right median cubital vein has been gained, a bolus injection of the contrast media, Uroselectan (42%), is administered.
Small molecules such as oxygen and carbon dioxide can diffuse in and out of the cells through the phospholipid bilayer; ions and glucose molecules enter and leave the cell via the channel proteins. Waste products such as nitrogenous compounds are carried to the kidneys and are excreted in the form of urine. Antidiuretic hormone, (ADH), is a hormone secreted by the pituitary gland. It is carried by the plasma to the kidney and stimulate the occurrence of water reabsorption. When the body is dehydrated, ADH is released, causing the collecting ducts to become more permeable.
If there isn’t proper circulatory motion in the system sometimes the nodes can swell up and infect the tissues they are underneath. Usually the infection of lymph nodes can be prevented by proper exercise or maybe even a regulation with medicine of your plasma from your blood. Lymph vessels, called lacteals, are present in the lining of the gastrointestinal tract. While most other nutrients absorbed by the small intestine are passed on to the portal venous system to drain, via the portal vein, into the liver, for processing, fats
Each renal artery enters its respective kidney at the renal hilus and divides into interlobar arteries. These arteries divide into smaller arcuate arteries and interlobular arteries. The smallest branches of the interlobular arteries are the afferent arterioles which carry blood into the glomerulus a knot of capillaries at the core of each nephron. The afferent arterioles are also lined with juxtaglomerular cells which help to control blood pressure.Each glomerulus is surrounded by a cup-shaped structure call Bowman's capsule. The blood pressure in the glomerulus is high enough that about 10% of the blood fluid volume is squeezed out and absorbed by the Bowman's capsule.
So a drug requires a number of partitioning and diffusion step. In this route drug passes through cytoplasm of cells. This route is suitable for hydrophilic drugs and highly hydrated keratin gives aqueous pathway to the hydrophilic drugs. The drug passes through the corneocytes of stratum corneum. iii) Intercellular route :- Intercellular pathway the drug diffuses through the continuous lipid matrix present between the cells.
3 Role in disease 4 Diagnostic investigation 5 Other websites [change] Histology (The cells in the salivary gland) There are two types of epithelial cells in salivary glands. They make either mucous or serous secretions. The parotid gland makes serous secretions. The submandibular and submaxillary glands have both types of cells. They make a mixture of mucous and serous.
