Capillary

The lymphatic system consists of lymphatic capillaries and vessels, lymph nodes, the spleen, the thymus, the tonsils, and lymph itself. Some of the fluid that is deposited into the tissues from the blood is taken up by lymphatic capillaries where it becomes lymph. Lymphatic capillaries and vessels have valves that prevent back flow, ensuring one-way flow of lymphatic fluids. Lymphatic capillaries eventually converge to form lymphatic vessels, which are similar in comparison to veins. Lymphatic…

Tar in tobacco greatly increase the chance of developing emphysema. In a health person, gaseous exchange occurs within the alveoli (as seen in the diagram above) at a capillary level. Oxygen and CO2 simultaneously move between the sacs, to the capillaries. They are elastic and moist, to allow frictionless movement when breathing moving. (Healthline, 2012) have quantified that a smokers lungs are damaged in such a way that gaseous exchange and air flow is affected…

which carries urine through the medulla to the pelvis of the kidney. Glomerular ultrafiltration: Each Bowman's capsule is supplied with blood by an afferent arteriole. It branches inside the Bowman's capsule to form a knot of capillaries, the glomerulus. These join up again to form the efferent arteriole, which take blood away from the Bowman's capsule. The afferent arteriole is much wider than the efferent arteriole; this means that pressure is built up. …

energy for the cells in the body to keep functioning as well as developing. How is the function of transport of materials achieved by these systems? I) Transport of substances at gross level (via big blood vessels) and exchange of substances at the capillary level…

of the more obscure scientists, Christian Friedrich Schonbein was well known for his discovery of ozone as well as work on fuel cells. He along with Friedrich Goppelsroeder discovered and coined capillary analysis, and later on, paper chromatography. My project centers on ink chromatography and capillary action, both of which were discovered by Friedrich Goppelsroeder and Christian Friedrich Schonbein. Of the two men, Christian Friedrich Schonbein was a more intriguing scientist. Christian…

Glial Cells are supporting cells in the nervous system (central nervous system [CNS] and peripheral nervous system [PNS]) which aid in the efficiency of neural operations in the nervous system, (Carlson, 2013). Carlson (2013, p.36) indicates the general functions of the glial cells as: keeping neurons in place; supplying neurons with nutrients and the chemicals needed to communicate with each other; protecting neurons from each other to promote coherent messages; and “destroying and removing the…

oxidation dysfunction would be beneficial to HFPEF patients. Exercise training, as short as 3 months, is believed to be a good intervention for treating HFPEF. Exercise training increases type I fiber, skeletal muscle mitochondrial, and capillary density, and increases capillary transit time of red blood cells in the muscle which result in increased oxidation capacity and blood volume that lead to an increase in diffusive oxygen capacity and arteriovenous oxygen difference. There are only a few…

down across the respiratory membrane from the alveolar air into the blood, or carbon dioxide diffusing from the capillary into the alveolus. Pressure gradients, membrane thickness and surfaces areas all can affect how gases travel throughout the body. Systemic Gas exchange or internal respiration is the unloading of oxygen and the loading of carbon dioxide at the systemic capillaries.…

walls of the alveoli and adjacent capillaries into the red blood cells. Oxygen is then carried by the blood to the body tissues. Carbon dioxide produced by the body returns to the lung via the blood, it then diffused across the capillary and alveolar walls into the air to be removed from the body. The alveoli has a structure specialised for maximum gaseous exchange, Walls are thin” and fluid lined enabling gas to dissolve through walls easily, surrounded by capillaries and has a large surface…

the level of the alveoli, oxygen diffuses into the alveolar capillaries where it attaches to the hemoglobin molecule while carbon dioxide (CO2) diffuses into the alveoli where it is expelled during exhalation. The hemoglobin molecule then transports the oxygen through the blood to vital organs and tissue. A pressure gradient exists between the alveolus and the capillaries, which facilitates this diffusion of oxygen into the capillaries (Andreoli & Cecil,…
