Document Summary
Reduces the hearts ability to increase in rate. Block the calcium uptake in muscles in the heart. Inhibit the reuptake of noradrenaline into presynaptic neurons. Increase in blood pressure and heart rate and stroke volume. Increase venous and arterial tone by working on alpha1 receptor at the nerve endings. Vagal tone refers to the parasympathetic control of the heart. Vasomotor tone is responsible for the slight constriction of the blood vessels. Provide an example where this is not the case. Circulatory system for nutrients but uses tracheal system for gas transport. Just goes from water to mitochondria in the polyps. Capacitance is concentration of a gas at a given pressure. Slope of concentration of gas with partial pressure. Do partial pressure of the oxygen which is 160torr with the amount 1. 2ml. If air on top of water --> oxygen diffuses to have same partial pressure. Eg carbon dioxide and water making carbonic acid.
