and Circulatory are responsible to carry out the gas exchange. The Respiratory system is composed of nose‚ larynx‚ pharynx‚ trachea‚ bronchi‚ bronchioles‚ pleura‚ alveoli and diaphragm. The Circulatory system consists of the heart‚ blood vessels‚ arteries‚ arterioles‚ veins‚ venules‚ capillaries and blood. In this lab‚ we will only focus on the circulatory system. The heart is the main component of the circulatory system because it is responsible for supplying oxygen-rich blood and nutrients to the

cava‚ while the left atrium receives blood from the lungs through the pulmonary veins‚ two from the right lung and two from the left lung. However‚ the right and left ventricles forms the two lower cardiac chambers that collect blood from the upper chambers pumping it out of the heart. As follows‚ the right ventricle pumps oxygen-poor blood through the pulmonary trunk‚ which divides it to form the left and right pulmonary arteries that lead to the lungs while the left ventricle pumps oxygen-rich blood

abnormal clinical condition involving impaired cardiac pumping that results in pathophysiologic changes in vasoconstriction and fluid retention” (Lewis‚ Heitkemper‚ Dirksen‚ O’Brien‚ Bucher‚ 2007‚ p. 821). Risk factors: Increasing age and coronary artery disease are the two main risk factors for heart failure. Heart failure may also develop by other contributing risk factors‚ such as cigarette smoking‚ diabetes‚ high cholesterol‚ obesity‚ and hypertension (Lewis‚ et al‚ 2007‚ p. 821). Other risk

clot inside the body. Other times‚ blood will pool in a vein due to improper blood circulation‚ and the stagnant blood will clot. Cracks in cholesterol plaques on the artery walls can also trigger clotting in the blood. Several problems can occur when blood clots form inside the body. First‚ the blood clot blocks the vein or artery‚ thus narrowing the passage and making it harder for blood to

experiment‚ several physiological parameters were observed in three patients before‚ during‚ and after moderate exercise. One of these parameters was the pulmonary airflow‚ which was recorded utilizing an Airflow Transducer. This device measures airflow using slight pressure differences created by the resistance of a screen inside the device. Pulmonary airflow is the rate of movement into and out of the lungs‚ and is directly proportional to the pressure difference of the intrapulmonary pressure and

Pump‚ Pump‚ Pump‚ is the sound of a human heart. The heart have 4 major veins they are the pulmonary veins. The pulmonary veins are large blood vessels that receive oxygenated blood from the lungs. A Cardiac surgeon is a person that works on the heart when there is a problem and cause. The heart is the most beautiful organ in the body there is. The heart is what keep the body alive and flows the blood. The development of cardiac surgery and cardiopulmonary bypass has lowered the rates of being performed

Capillaries exchange materials with the cells of the body there veins return blood to the heart and arteries take blood away from the heart 3. The SA node‚ or sinoatrial node initiates the heartbeat and automatically sends out a signal every 0.85 seconds‚ which causes the atria to contract. The AV node‚ or the atrioventraicular node‚ receives this signal

then returns to the heart from the body through the systemic veins. It returns to the right atrium‚ and is pumped to the right ventricle. From the right ventricle the blood is pumped through the pulmonary arteries to the lungs‚ where gas exchange occurs. The blood is returned to the heart through the pulmonary veins to the left atrium. Then it is pumped to the left ventricle to complete the circuit (1‚ 2). The pressure at which the heart pumps blood throughout the body must be able to overcome the
