PARASYMPATHETIC STIMULATION: hyperpolarizes the membrane potential, slows depolarization by changing K+ permeability Order the blood flows through the heart: 1. Flashcards. Ca2+ from ECF to ICF 5. As an artery, it contains thicker walls than veins because it has to withstand the tough pumping blood pressure of the heart. Oxygenated blood flows back to the heart from the lungs through the pulmonary vein, dumping into the left atrium. 3.

The specialized cell junctions between myocardial cells are called __________. 1. 3. pulmonary circulation The left ventricle pumps the oxygen-rich blood through the aortic valve into the aorta and out to the rest of the body. This is why the left ventricle needs to pump the blood by generating more force during contraction to do this. From the pulmonary trunk it moves into the right and left pulmonary arteries to the lungs. 7. Lets now use the 2x2 table we made in the anatomy of the heart post, and this will give us another way to visualize the blood flow through the heart.

Ventricular ejection 4. P wave - the top of the P wave indicates the beginning of atrial systole T/F: During the refractory period of cardiac muscle, the cell is likely to generate another action potential, T/F: The plateau phase of the action potential in cardiac muscle delays repolarization to the resting membrane potential; therefore the refractory period is prolonged, Ventricular contraction or ventricular systole. Happy learning!
