Please answer the following question: Q: How do glucose, ions, and other larger molecules leave the blood? Read this paragraph and choose the correct option from the provided answers: 20.3 | Capillary Exchange By the end of this section, you will be able to: Identify the primary mechanisms of capillary exchange Distinguish between capillary hydrostatic pressure and blood colloid osmotic pressure, explaining the contribution of each to net filtration pressure Compare filtration and reabsorption Explain the fate of fluid that is not reabsorbed from the tissues into the vascular capillaries The primary purpose of the cardiovascular system is to circulate gases, nutrients, wastes, and other substances to and from the cells of the body. Small molecules, such as gases, lipids, and lipid-soluble molecules, can diffuse directly through the membranes of the endothelial cells of the capillary wall. Glucose, amino acids, and ionsincluding sodium, potassium, calcium, and chlorideuse transporters to move through specific channels in the membrane by facilitated diffusion. Glucose, ions, and larger molecules may also leave the blood through intercellular clefts. Larger molecules can pass through the pores of fenestrated capillaries, and even large plasma proteins can pass through the great gaps in the sinusoids. Some large proteins in blood plasma can move into and out of the endothelial cells packaged within vesicles by endocytosis and exocytosis. Water moves by osmosis. Choices: - through cell membranes - through capillary tips - through veinous fissures - through intercellular clefts A:
Answer:
through intercellular clefts
