One form of hydrostatic pressure is blood pressure, the force exerted by blood upon the walls of the blood vessels or the chambers of the heart. It also discusses resistance which is due to factors that impede or slow blood flow.Īs noted earlier, hydrostatic pressure is the force exerted by a fluid due to gravitational pull, usually against the wall of the container in which it is located. This section discusses a number of critical variables that contribute to blood flow throughout the body. Ventricular contraction ejects blood into the major arteries, resulting in flow from regions of higher pressure to regions of lower pressure. If we consider the entire cardiovascular system, blood flow equals cardiac output. It is initiated by the contraction of the ventricles of the heart. Discuss several factors affecting blood flow in the venous systemīlood flow refers to the movement of blood through a vessel, tissue, or organ, and is usually expressed in terms of volume of blood per unit of time.Identify and discuss five variables affecting arterial blood flow and blood pressure.Describe the clinical measurement of pulse and blood pressure.Distinguish between systolic pressure, diastolic pressure, pulse pressure, and mean arterial pressure.It reflects the extent of systematic inflammation The reason behind this experiment is to create awareness about the unknown cardiovascular diseases which can be determined by the erythrocyte sedimentation rate.By the end of this section, you will be able to: To perform the test, non clotting blood is placed in a vertical tube (Westergren) and ESR is measured and reported in units of mm/hr. It is a common haematological non specific indicator of inflammation. The rate of sedimentation in a period of one hour called ESR and also Biernack test. Both RBC deform ability and plasma proteins have a role to play in erythrocyte aggregation. Increased amount of RBC in blood causes relative increase in blood viscosity. Blood viscosity is a measure of resistance of blood to flow, which is described as thickness and stickiness of blood. To determine the cardiovascular risk factors linked independently to blood viscosity. The aim of the experiment is to compare the blood viscosity levels in different kinds of patients by studying the erythrocyte sedimentation rate. strict warning: Declaration of views_plugin_row::options_submit() should be compatible with views_plugin::options_submit(&$form, &$form_state) in /home4/moshika/public_html//sites/all/modules/views/plugins/views_plugin_row.inc on line 134. ![]() strict warning: Declaration of views_plugin_row::options_validate() should be compatible with views_plugin::options_validate(&$form, &$form_state) in /home4/moshika/public_html//sites/all/modules/views/plugins/views_plugin_row.inc on line 134.strict warning: Declaration of views_handler_filter_term_node_tid::value_validate() should be compatible with views_handler_filter::value_validate($form, &$form_state) in /home4/moshika/public_html//sites/all/modules/views/modules/taxonomy/views_handler_filter_term_node_tid.inc on line 302.strict warning: Declaration of views_handler_filter_boolean_operator::value_validate() should be compatible with views_handler_filter::value_validate($form, &$form_state) in /home4/moshika/public_html//sites/all/modules/views/handlers/views_handler_filter_boolean_operator.inc on line 159.strict warning: Declaration of views_handler_filter::options_submit() should be compatible with views_handler::options_submit($form, &$form_state) in /home4/moshika/public_html//sites/all/modules/views/handlers/views_handler_filter.inc on line 607.strict warning: Declaration of views_handler_filter::options_validate() should be compatible with views_handler::options_validate($form, &$form_state) in /home4/moshika/public_html//sites/all/modules/views/handlers/views_handler_filter.inc on line 607.strict warning: Declaration of views_handler_argument::init() should be compatible with views_handler::init(&$view, $options) in /home4/moshika/public_html//sites/all/modules/views/handlers/views_handler_argument.inc on line 744.strict warning: Non-static method view::load() should not be called statically in /home4/moshika/public_html//sites/all/modules/views/views.module on line 906.
