Thrombin stimulates the clotting pathway.
Left AV valve stenosis would be expected to alter the electrocardiogram. Sympathetic stimulation would decrease venous pressure and venous return. The total peripheral resistance can increase with no change in pulse pressure. Diffusion of O2 and CO2 is dependent on the partial pressure of the gas. The diaphragm and external intercostal muscles are muscle of inspiration.
