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.
A SecondsCount.org answered. Most veins carry blood that is low in oxygen back to the heart. After the oxygen and nutrients have been delivered to the bodyâs tissues by the arteries and capillaries, a second network of venules and veins carries blood and waste products back to the heart. Smaller tubes, venules, pick up the oxygen-depleted blood and transfer it to the veins, which carry it back to the heart. Once the veins return blood to the heart, it is pumped to the lungs. Here, the carbon dioxide from the venous blood is expelled as we breathe out. The oxygen we breathe in is picked up by the blood flowing through the lungs.
