Document Summary
Right side of heard is smaller and the left side. Why do we see both of these size relationships (above and only 1 answer) The heart is a muscle, it will contract. The squeeze at the end will most likely be like skeletal muscle. Two cells next to each other, one is pulling. Desmosomes: to provide strict to hold two cells together. When 1 moves the other goes with it. Gap junction: movement between the two cells, stay as electrical synapse between the two cells, faster electrical movement. Can go in two directions but we make sure it stays in one direction. Voltage-gated channels not in sr but instead in the transverse tubules for calcium to go through. Move though fluid inside tt called interstitial fluid to get to cytosol. Binds to chemically gated ca2+ channels in the sr, which allows ca2+ release. Need pumps to cause cytosol level to go to 0.
