pumping motion. The principle of the heart-lung machine (also known cardiopulmonary bypass) is actually quite simple. It permits the heart to be operated on safely by maintaining the circulation of oxygenated blood throughout the cardiovascular system. It represents a continuous loop; as the rich-oxygen blood goes into the body‚ poor-oxygen blood returns from the body and is drained into the pump completing the circuit. The machine basically consists of a pump (to replace the heart) and an oxygenator

states‚” The normal‚ healthy liver can process about 1/2 ounce of pure alcohol (that’s 6 to 12 ounces of beer‚ 5 ounces of wine‚ or 1 ounce of spirits) in an hour. The rest flows on to your heart.” Your heart contracts less when alcohol is in your system‚ lowering your blood pressure. Alcohol then flows through your hearts bloodstream to your lungs. Alcohol can be smelled on your breath now‚ taking a breathalyzer test determines your BAL. For example‚ speech and the ability to walk are impaired

1.a. Increase pressure from the thoracic cavity onto the venae cavae causes the stroke volume to decreases‚ cardiac output would decrease‚ venous blood pressure would eventually increase and venous return would also eventually increase. b. Fainting is due to a drop in blood flow to the brain. And holding your breath causes the heart rate to slow and blood vessels to dilate‚ which then leads to blood pools in the lower body and less blood going up to the brain. c. Compensatory mechanism that become

Oxygen is a vital element for most of the organisms on earth. It was also thought to be the necessity for complex life until the anaerobic animals were discovered [1]. Although it is not the main requirement for all of the organisms in Kingdom Animalia‚ it carries out many important tasks in human bodies like the production of energy and oxidation-reduction cycle. Every day our bodies produce ATP as much as our body weight and even a slight drop in that production results in tiredness and moreover

Introduction Complete atrioventricular canal defect (CAVC) is a heart condition in which there is a large hole in the center of the heart and only one heart valve. Normally‚ the heart is divided into four chambers‚ and there is one valve on each side of the heart. The chambers on the right side of the heart receive blood from the body and pump it to the lungs where the blood gets oxygen. The chambers on the left side of the heart get the oxygen-rich blood from the lungs and pump it back out to the
