The cardiovascular system consists of : heart (심장)‚ and vessels (혈관)‚ arteries (동맥)‚ capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs‚ alveolar capillaries‚ and pulmonary veins

heating in the treatment of arthritis. The cerebral ventricular geometry has been portrayed by means of ultrasonic techniques. The head is immersed in water. An underwater projector sends an ultrasonic wave through the head. A hydrophone picks up the transmitted sound. A frequency of 2.5 megacycles was used. A scanning system together with a facsimile-type recorder presents the ultrasonogram in the form of a picture showing the cerebral ventricular geometry. This method provides a means for the

stenosis is characterized by the left ventricular pressure being much greater that the aortic pressure during left ventricular ejection. The pressure gradient across the stenotic lesion results from both increased resistance (related to narrowing of the valve) and turbulence distal to the valve. The magnitude of the pressure changes is determined by the severity of the stenosis and the flow rate across the valve. Severe aortic stenosis results in reduced ventricular stroke volume due to increased afterload

Nancy Yedanapalli physio ex Activity 6 1. Explain why the larger waves seen on the oscilloscope represent ventricular contraction. a. The ventricular contraction is of greater force than the atrial contraction‚ since the ventricular contraction functions to send blood throughout the entire body (systemic circulation)‚ where as the contraction of the atrium send blood only to the lungs and rest of the the heart (pulmonary circulation). 2. Explain why the amplitude

The three different waveforms are a representation of the electrical activity of the heart. The P wave represents the depolarization of the atrial valve. The QRS complex represents the depolarization of the ventricular valve. Also‚ the T wave represents the repolarization of the ventricular valve. The change in amplitude represents the different heartbeat patterns such as normal‚ fast‚ slow‚ or irregular heartbeats. 8. In addition‚ the waveforms of the other subjects do not have the same amplitudes
