have to push the blood to our head and feet continuously. Circulation is the blood flow around our bodies. The heart connects the two major portions of the circulation’s continuous circuit‚ the systemic circulation and the pulmonary circulation. The blood vessels in the pulmonary circulation carry the blood through the lungs where the gasses oxygen and carbon dioxide are exchanged. While the blood vessels in the systemic circulation carry the blood throughout the rest of our body (Martini & Bartholomew

Essay on Congestive Heart Failure According to a recent study‚ people over 40 have a 1 in 5 chance of developing Congestive Heart Failure in their lifetime. Nearly 5 million people in the United States—mostly older adults—already have Congestive Heart Failure‚ and the number of people with Congestive Heart Failure keeps rising. About 550‚000 people develop Congestive Heart Failure each year. This is because people are living longer and surviving heart attacks and other medical conditions that

Condition Congestive Heart Failure: A Cardiovascular Condition Congestive Heart Failure is not a disease‚ but a condition in which the heart is unable to pump enough blood needed to meet the cardiac demands of the body and facilitate systemic circulation. Congestive Heart Failure can be right or left-sided‚ and is mainly a fluid issue‚ in which there is a decreased amount of blood to the kidneys. In children‚ CHF can be long term and is most common in infants; it can also result from heart failure

3. What is pulmonary circulation? Pulmonary circulation is the movement of blood from the heart‚ to the lungs‚ and back to the heart. 4. The sound you hear when you listen to your heart with a stethoscope is actually what? The sound you hear through a stethoscope is your valves shutting to prevent blood from flowing the wrong way. 5. Distinguish between systole and diastole phases of the heart. During the systole phase‚ the right ventricle is sending blood into the pulmonary artery and the

form a "horseshoe- shaped" cluster anterior and lateral to the brain plate. Following cardiac mesoderm involution during gastrulation‚ the two endocardial tubes fuse along the embryonic midline. The heart starts to beat at day 22‚ but the circulation does not start until days 27 to 29. The single tubular heart develops many constrictions outlining future structures. Prior to looping the heart tubes forms constrictions defining separate components of the heart‚ these are (cranial to caudal):

embolization to the pulmonary circulation. Patient T.V. has recently had abdominal surgery and is now in the hospital to treat DVT in her left leg. After the third day she begins having shortness of breath and supplemental oxygen is needed. Considering T.V.’s history and her recent abdominal surgery‚ she is most likely experiencing respiratory distress due to pulmonary emboli. DVT is the most frequent source of pulmonary emboli‚ which is a blockage in the main artery of the lung. Pulmonary embolism is usually
