Cardiac Output most used tool to measure heart function The volume of blood ejected by the heart per minute. CO= Heart Rate x Stroke Volume EX: 70bt/min X 70ml/bt = 4900ml/min ~ 5L/min Regulation of Heart Beat HR is regulated through the balance of parasympathetic and sympathetic influence on the SA node. 1 action potential = 1 electrical impulse Parasympathetic: Slows HR Sympathetic: Speeds HR Parasympathetic Regulation of HR At rest‚ parasympathetic nerves will release Acetylcholine

Extraction is a method used for separating and isolating materials. A compound is pulled from solvent A to solvent B and in this case‚ both solvents are miscible. These two concepts are not capable of mixing together; when they are mixed together‚ they form a bilayer. This can be seen when mixing oil and water together. When thinking of extractions‚ one can picture how coffee gets extracted. The flavors‚ molecules‚ caffeine‚ etc. are extracted from the coffee beans. In this experiment‚ a solution

SYNTHETIC EXPLOITATION OF ENZYMES: BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting

Water as a Universal Solvent * Because of its high polarity‚ water is able to dissolve most substances. * In a solution‚ the positive hydrogen side of water is attracted to the negative parts if the compound it is dissolving while the negative oxygen is attracted to the positive parts * “Like dissolves like” – describes whether one substance will dissolve in another. Water for example can’t dissolve nonpolar substances Concentrations on Solutions * Solvent: The liquid in which

The Federal Bureau of Investigation tracks four offenses murder‚ forcible rape‚ robbery‚ and aggravated assault in its Violent Crime Index. The juvenile arrest rate for each of these offenses has been declining steadily since the mid-1990s. The murder rate fell 70% from its 1993 peak through 2001 (Snyder‚ 2003). Statistics: Research has shown that crimes committed by juveniles are more likely to be cleared by law enforcement than crimes committed by adults. The clearance data in the Crime in the

It would be prudent to understand how the heart functions in the first place before going in depth into the various problems that might arise within the cardiac cycle. Of which a large number are covered under the various Arrhythmias‚ which can be divided into two major groups‚ ventricular arrythythmias and supraventricular arrythythmias. I.e.‚ arrythythmias that occur in the ventricles and arrythythmias
