from the Water will also aid the body in becoming dehydrated this will cause the viscosity (the resistance of blood flow) of the blood to become higher‚ making it harder for it to flow through the blood stream imposing Venous return (the rate of blood flow back to the heart.) venous return normally limits Cardiac output (the amount of blood pumped out of a ventricle per beat). Cardiac output is calculated as the product of stroke volume (the volume of blood pumped from one ventricle of the heart

Complete information on the mechanism of Respiratory System in Man NIRMALA AGARWAL Respiratory organs are those which are concerned with the passage of the air to and from the lungs. The latter are‚ of course‚ mot important of all. The passage is also called respiratory tract. For the sake of convenience‚ the respiratory tract can be divided into upper and lower parts. The upper part extends from the external nostrils (external openings of nose) to the vocal sac present in the neck. The lower part

ventricles Important determinant of cardiac output Correlates with cardiac function Frank-starling Law SV is intrinsically controlled by preload (the degree to which the ventricles are stretched prior to contracting ). An increase in the volume or speed of venous return will increase preload‚ through the Frank-Starling law of the heart‚ will increase the stroke volume. Decreased return will have opposite effect‚ causing a reduction in stroke volume End Systolic Volume the volume blood in the ventricle at the

Bone marrow is a spongy substance inside our bones where our body synthesizes and stocks blood cells. While it’s damaged‚ it makes very little blood cells and in-sufficient cells for our immune system. A transplant replaces impaired bone marrow with healthy marrow cells. It can preserve certain diseases or some forms of cancer. It also conveys a long recovery process and a risk of severe side effects. If you or any member of your family is thinking about having one‚ you should know about all the

case of tamponade clinical symptoms may include coughing‚ dyspnea‚ hoarseness. Physical examination will reveal classical tamponade signs which is known as Beck’s triad. Hypotension occurs because of decreased stroke volume‚ jugular-venous distension due to impaired venous return to the heart‚ and muffled heart sounds due to fluid inside the pericardium. Other signs of tamponade include pulsus paradoxus and ST segment changes on the electrocardiogram which may also show low voltage QRS complexes as
