Do all veins carry deoxygenated blood at a low pressure? Explain the relationship between structure and function of ultrafiltration
No, the pulmonary vein carries oxygenated blood as it comes from the lungs but at low pressure so that it does not rupture/damage the alveoli. As the blood moves into the kidney via afferent arterioles it enters a knot-like capillary tuft called a glomerulus. This glomerulus is encapsulated by the Bowman’s capsule, which is comprised of an inner surface of cells called podocytes. Podocytes have cellular extensions called pedicels that wrap around the blood vessels of the glomerulus. Between the podocytes and the glomerulus is a glycoprotein matrix called the basement membrane that filters the blood. Glomerular blood vessels are fenestrated (have pores) which means blood can freely exit the glomerulus. The podocytes of the Bowman’s capsule have gaps between their pedicels, allowing for fluid to move freely into the nephron. Consequently, the basement membrane functions as the sole filtration barrier within the nephron. The basement membrane is size-selective and restricts the passage of blood cells and large proteins. Hence when the blood is filtered, the filtrate formed does not contain any blood cells, platelets or plasma proteins.
