Terms | Definitions | Explan why the larger waves seen on the oscilloscope represent ventricular contraction | the ventricle contraction is of greater force than the atrial contraction‚ this is due to the fact that ventricle’s fxn is to send blood throughout the body. | Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation in cardiac muscle. | amplitude does not change because the cardiacs long refractory period prevents summation. | Why is

10 American Inventions That Changed the World From the mundane to the truly spectacular‚ numerous American inventions have changed the world. Here is a countdown of ten things invented by Americans that have become part of our everyday lives here and across the world. 10. If you find buttons quite a fuss as you dress up for work‚ then you have to thank Whitcomb L. Judson‚ an inventor from Chicago‚ for inventing the clasp locker‚ the zipper’s predecessor which was introduced in 1893. The modern

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

Unit 5 task 3 (P5 M2 D2) – explain the concept of homeostasis‚ discuss the probable homeostatic response to changes in the internal environment during exercise‚ how homeostatic mechanisms control temperature‚ breathing and heart rate and evaluate the importance of homeostasis in maintaining healthy functioning of the body. Homeostasis Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits‚ it also maintains

effective and ultimately leaving more residual blood in the left ventricle meanwhile decreasing stroke volume and increasing blood pressure. Increased pressure causes the left ventricle to hypertrophy which also puts pressure on the left atria. Atrial pressure is meant to be low so when ventricular pressure rises‚ it ends up transmitting pressure all the way back to the pulmonary venous circuit. The pulmonary venous system is normally meant to bring oxygenated blood back to the left side of the
