central pump that keeps the blood moving around the body. When air is inhaled‚ it enters the lungs and diffuses through the alveoli; the oxygen binds with the hemoglobin of the red blood cells to form oxyhemoglobin. The blood then enters the pulmonary circulation system‚ where it gets pumped round to cells that require energy for cellular respiration. Oxygen diffuses out of the red blood cells and carbon dioxide diffuses in making the blood deoxygenated‚

Plaques (atheromas) deposited in the walls of arteries are major causes of heart disease‚ chest pain (angina pectoris)‚ heart attacks‚ and other disorders of the circulation. In atherosclerosis yellowish plaques of cholesterol‚ fats‚ and other remains are deposited in the walls of large and medium-sized arteries. Atherosclerosis usually occurs with aging. It is linked to overweight‚ high blood pressure‚ and diabetes

Maternal mortality due to sepsis is worryingly increasing through developed and developing countries. This is despite a worldwide effort towards reducing maternal death‚ maternal sepsis during pregnancy remains one of the worlds leading causes of preventable maternal death. In developed countries 3% of all maternal mortality is due to sepsis‚ whilst that figure jumps to 12% in developing countries. Pregnancy affected by severe sepsis or septci shock‚ run the risk of pre-term labour‚ fetal infect

Unit One: Animal Structures and Functions‚ Answers to Review Questions Respiratory System 1. Indicate the importance of gas exchange in all living organisms. Respiration is gas exchange (Oxygen and Carbon Dioxide) with the external environment. All living things respire. Gas exchange is important so that cellular respiration can take place and energy can be made for the cells. 2. Distinguish among the terms cellular respiration‚ external respiration and internal respiration

I will enter from the right femoral vein and follow a path to the lower lobe of the right lung via the right pulmonary artery. I will be describing the structures that I pass by and through. Once I have reached the lung‚ I will describe the structures that I see and discuss how the body fights against the invader. After that I will exit the body cross the alveolar

Tobacco Nicotine use is a leading preventable cause of death in the world‚ directly and indirectly responsible for 440‚000 deaths per year. The health problems that result in tobacco use tally an annual of $75 billion in direct medical costs (Slovic 36). That money spent on medical problems for smokers should be used to pay for more important things in our society such as schools‚ libraries‚ childcare‚ etc. Because it takes approximately eight seconds for nicotine to reach the brain and each

Periodontal disease has been vividly studied and the absolute foundation of the multifactorial process restrictive airways. The infection leads to inflammatory responses that perpetuates the diseased state via inflammatory mediators‚ and thus mediating copd. Counter arguments
