The Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of _heart depolarization___. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA Node __initiates the depolarizing

The cardiac conduction system of the heart consists of specialized muscle cells that generate and send rhythmic electrical impulses to the myocardium in order for the heart to contract (Cardiac Conduction System‚ 2016). When there is the normal rhythm of the heart it is called sinus rhythm and any deviation from sinus rhythm is called an arrhythmia (Saladin‚ 2012). Electrocardiograms (ECG) record the electrical impulses and help determine when there are any abnormalities in the way the heart functions

nductioIn heat transfer‚ conduction (or heat conduction) is the transfer of heat energy by microscopic diffusion and collisions of particles or quasi-particles within a body due to a temperature gradient. The microscopically diffusing and colliding objects include molecules‚ electrons‚ atoms‚ and phonons. They transfer microscopically disorganized kinetic and potential energy‚ which are jointly known as internal energy. Conduction takes place in all forms of ponderable matter‚ such as solids‚ liquids

Steven Ofstedahl BI 243 Short report Cardiac Arrest The circulatory system along with the heart make are what make up the cardiovascular system. The heart works as a pump that pushes blood to tissues‚ organs and cells in your body. The blood can be pumped throughout the body through a series of arteries‚ veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body‚ while veins help bring that blood back to the heart. Arteries carries oxygenated blood away

Cardiac Surgeon Cardiac surgeons treat valvular heart diseases such as valve stenosis or vessel insufficiency‚ ischemic heart disease‚ coronary artery disease‚ atherosclerosis and congenital defects. They treat these diseases by repairing or replacing heart valves‚ widen clogged arteries‚ repair aortic aneurysms‚ implant defibrillators and pacemakers‚ and perform double‚ triple‚ quadruple‚ and sometimes even quintuple heart bypasses. Cardiac surgeons must complete internships and residency requirements

Electrolytic Conduction Introduction Electrical conductors can be classified into two types: (1) electronic conductors and (2) electrolytic conductors. Solid and molten metals‚ semiconductors‚ and some salts are examples of electronic conductors. Conduction takes place in electronic conductors by direct migration of electrons through the conductor under the influence of an applied potential. Here the atoms or ions that compose the conductor remain stationary (except for vibrations about
