Capillary

Each 'granule' contains a loop of capillaries and therefore bleeds easily if traumatised. Granulation tissue is made up mainly of proliferating fibroblasts, capillaries and tissue macrophages in a matrix of collagen, glycosaminoglycans (GAGs) including HA, and the glycoproteins fibronectin and tenascin [13], [14]. Granulation tissue formation is evident…

retinopathy, the capillaries of the retina become more permeable. This can cause fluid exudation (hard exudates) into the retina, these appear as small well defined yellowish white patches. Micro aneurysms can develop, which can rupture causing small bleeds. Arterial occlusions due to poor oxygenation of the nerve fibres by the retinal capillaries (Morrison) cause retinal infarcts ‘cotton wool spots’ on the retina. Thickening of the basement membranes of the retinal capillaries can also occur.…

when the heart contracts because it is pumping the oxygenated blood through the aorta. Then the blood goes through your heart through the vena cava. Once you start moving the blood go through the capillaries to your lungs, legs, head and arms the blood flows through the inferior and superior capillaries. The part of the heart blood that that keeps the blood from flowing backwards would be the valves. Hypothesis: I hypothesize that if the faster and more often we move our muscles the higher our…

disease is the lung cancer that is cause by mutation of nucleus in some of the cells lining in the respiratory tract because of the deposit of chemicals from tobacco. The tumors can grow very large, so small pieces may divide and carried by the blood capillaries and then, spread to others parts of the human body. Finally, smoking can interfere every function of each parts of the respiratory system, and it can also cause lung cancer. Smoking can cause cancer, bronchitis and pneumonia not only…

pumping blood to body tissues and organs; maintaining homeostasis; and transport gases, waste, and hormones. The different types of blood vessels are: arteries, capillaries, and veins. The vessels that carry blood towards the heart are veins and the vessels that carry blood away from the heart are arteries. Gas exchange occurs in the capillaries. 2. Describe the layers of blood vessels. Describe the differences between arteries and veins. The layers of blood vessels are: a hollow interior…

adapted for this function as well it is the recommended route. The nose consists of fine bones which are placed on the side walls; they are a curled shape and are coated with a moist mucous membrane. These curled shape bones are rich in blood capillaries. This structure gives a large surface area for air to smoothly pass over, this makes well adapted to its function. The moist mucous membrane warms the air as it comes through the air passages, as it reaches the throat the air has almost become…

that contains a glomerulus, bowman's capsule, capillaries, veins, arteries, the Loop of henle, and a collection duct. As we go along this speech you will figure out what some of the parts are. The nephrons have to filter the blood, but where do they get it from? The constant supply of blood comes from the arteriole, a venue, and a network of capillaries connecting them. Blood that enters the nephron goes into the glomerulus which is a network of capillaries that are inside a cupped shaped…

liver before absorption. Fentanyl can also be administred by sublingual route and buccal route. By sublingual route, the rate of absorption is also high because there are many capillaries under the tongue. By buccal route, there are many capillaries in buccal cavity. Fentanyl can enter the blood rapidly through capillaries by sublingual route and buccal route. The bioavailability of drugs by buccal and sublingual routes are high because drugs can enter bloodstream without passing through liver.…

this paper chromatography experiment, the mixture to be separated was spotted 1.5 centimeters from the bottom of chromatography paper, which was then dipped in the solvent, a 0.1 percent salt solution. The solvent then moved up the filter paper via capillary action and carried the mixture's pigments with it (Rosen and Gothard, 2010). Each pigment has a unique retention factor or Rf, a ratio between how far a pigment travels to the distance…

The three basic types of blood vessels, including capillaries, arteries and veins. • Arteries take oxygen-rich blood away from heart. • Veins take blood back toward heart. • Capillaries are very tiny blood vessels that form a connection between arteries and veins. Transfer of nutrients, oxygen and wastes in and out of body facilitated by the capillary. 3. The Blood The heart pumps blood throughout body. The blood is a substance that carries water,…
