Question

Organ systems do not function independently, rather they are integrated anddepend on each other for optimum health. Using the cardiovascular system and therespiratory system, give an overview of system integration

Answer 1

Overview of system integration in cardiovascular and respiratory system

           * Both cardiovascular and respiratory system work toghether to meet the oxygen demand of

              all cells of the body.

          * Deoxygenated blood enter into the right atrium through superior and inferior vena cava goes

             in the right ventricle during atrial contraction or atrial systole.

          * Blood enter into right ventricle go to pulmonary artery when pulmonary valves opens during

            ventricular contraction or ventricular systole.

          * Blood in the pulmonary artery enter into pulmonary capillaries within the walls of the small

            air passages and alveoli of the lungs in the respiratory system.

          * Gaseous exchange take place in the alveoli near the pulmonary capilllaries and release

             carbon dioxide and allow oxygen to enter into the blood due to negative pressure of the

             thoracic cavity during inspiration.

         * From the pulmonary capillary oxygenated blood enter into the left atrium through pulmonary

           veins came from the pulmonary capillaries.

        * Blood enter into the left atrium go to left ventricle during left atrial systole or contraction.

        * From the left ventricle this oxygenated blood goes to aorta through relaxation of aortic valve.

        * Blood enter into the aorta go to upper and lower part of the body through it's branchs and

          meet the oxygen and nutrient demands of the body.
