Yes, the transducer cable can be cut. However, if the transducer came with a connector do not cut it off. The molded on connector is waterproof. You need to cut and splice the cable away from the connector using Airmar's splash-proof Junction Box.
Veins carry blood back to the heart, having picked up (via capillaries) carbon dioxide as a waste product from the respiration of individual cells. Veins also carry nutrients that were absorbed through the lining of the intestines and into the blood carried in tiny capillaries.
Arteries carry blood away from the heart, while veins carry blood towards the heart. Capillaries carry blood from arteries to veins. Arteries generally carry oxygenated blood from the heart to the tissues and organs during the systolic heartbeat cycle. They are under high pressure. (the only exception is the pulmonary arteries which carries deoxygenated blood from the heart to the lungs).
