arteries. Diastolic Blood pressure is the remaining pressure in the arteries when the ventricles of the heart is relaxed allowing the heart to fill with blood. Blood pressure is influenced by cardiac output (CO) and systemic vascular resistance (SVR). The formula to determine blood pressures is BP=CO x SVR. Cardiac output is the amount of blood pumped by each ventricle in 1 minute. Systemic vascular resistance is the force formed in the small arteries

Crimes of the Heart: A Case Study on Cardiac Anatomy Tiffany is worried about her newborn son. Ever since she brought Caleb home from the hospital it has been so hard to get him to eat and he seems to be breathing too hard all the time. At his one month check-up‚ the nurse tells her that Caleb has only gained one pound since he was born and Tiffany breaks into tears. Dr. Baker checks over Caleb in the exam room‚ taking extra time feeling and listening to his chest. After the exam Dr. Baker says

pulse pressure was 45 (SP – DP). My mean arterial pressure was 93 (DP + 1/3 (SP – DP). 2. Mean arterial blood pressure is determined by cardiac output and total vascular resistance. The mathematical equation for mean arterial blood pressure is equal to cardiac output x total vascular resistance. The amount of blood pumped out of the heart is the cardiac output‚ and the sum of the resistance of all systemic blood vessels is equal to the total vascular resistance. An increase of blood volume‚ heart

variable voltage output depending upon the vibrations given on the crystal surface. This voltage is converted to current using suitable converter. Now the current is passed through a memristor‚ which has a corresponding resistance value. Whenever the current increases‚ the resistance value increases and the change in resistance is detected using a microwave generator connected at the end. Using the microwave level‚ an external device (similar to a watch) has been programmed to detect cardiac arrest and

4 CIRCULATORY SYSTEM The circulatory system contains several very different components‚ including the heart‚ a hollow muscular pump that stands at the operational center of the system that pumps liquid blood throughout the body through three types of flexible tubes‚ the blood vessels (Fig. 4.1). The arteries channel blood from the heart to all parts of the body needing service. Once there‚ the blood passes through narrow arteries and enters the capillaries‚ which are the narrowest blood vessels
