The structure of a nerve cell that conducts impulses away from the cell body. The axon is the part of a neuron that transmits electrical impulses away from the cell body to other neurons, muscles, or glands. A. Axon 17. The blood vessel most likely to contain food nutrients a few hours after eating a heavy meal. The hepatic portal vein carries nutrient-rich blood directly from the digestive organs (like the small intestine) to the liver for processing after a meal. A. Hepatic portal vein 18. The structure in Spirogyra that enables it to carry out autotrophic nutrition. Spirogyra is a type of green algae that performs photosynthesis, and this process occurs in its chloroplasts, which contain chlorophyll. B. Chloroplast 19. Which of the following structure is involved in gaseous exchange in the lungs?
