most important systems in the body is the lymphatic system. One of many functions in the lymphatic system is to cleanse leaked plasma of bacteria and other foreign substances and return it to the blood stream. This also acts as a surveillance system for immune system cells. Another function of the lymphatic system is to stop or slow pathogen entry‚ prevent disease-causing microorganisms from spreading and to strengthen the response of the immune system. Also‚ the lymphatic system protects against

Introduction Lumbriculus variegatus‚ or blackworms‚ are part of the segmented worms called annelids. The body is organized into repeated segments. It has a closed circulatory system‚ similar to humans because the blood is contained within blood vessels. Two major blood vessels‚ the ventral and dorsal vessels‚ run straight from the head to the tail‚ and several vessels connect the two in the anterior segments. The dorsal blood vessel acts similar to the heart‚ pumping the blood through wavelike contractions

Educators have used computers and other information technologies as tools to increase student learning in America’s elementary and secondary schools for over 30 years. The 1960s brought computer-assisted instruction (CAI) to schools. CAI was developed to help students acquire basic skills‚ practice them‚ and measure learning gains. With the development and increased availability of lower-cost personal computers‚ the use of technology in schools broadened in the early 1980s to encompass the use

in 1883. Under the direction of the cardiovascual physiologist Carl Ludwig and the gastrointestinal physiologist Rudolf Heidenhain he studied during 1884-86. Working with Ludwig‚ Pavlov’s first research on his own was on the physiology of the circulatory system. In the laboratory of Botkin which was located in St. Petersburg‚ he investigate cardiac physiology and regulating blood pressure. Pavlov became a very skillful surgeon and he was so skillful that he was able to put a catheter into the femoral

imbalance of hypertension is a major cause of heart failure‚ vascular disease‚ renal failure‚ and stroke due to several factors heredity‚ diet‚ obesity‚ age (over 40)‚ stress‚ diabetes‚ and smoking. The feedback system cannot maintain homeostasis in hypertension because the circulatory system is responsible for transporting nutrients‚ hormones‚ and oxygen to the cells of the body. Your muscles send signals to the brain that they need more oxygen so the heart beats faster and harder to deliver more oxygen

Zi Lin January 25‚ 2014 2B Cardiovascular Diseases The heart is an essential organ in the cardiovascular system responsible for pumping oxygen and nutrition filled blood to all parts of the human body. It is composed of four chambers; two upper chambers called the right and left atrium‚ and two lower chambers called the right and left ventricle. A structure called the septum is what divides the heart into right and left halves. Four heart valves keep the flow of blood in one direction. At rest‚ the

Physiology of the Circulatory System Activity 1) When a person goes from a prone position to standing up‚ all of the blood rushes from to the feet due to gravity. This causes reduced blood flow back to the heart‚ which in turn causes reduced cardiac output. The baroreceptors help to increase blood pressure and heart rate as seen through the baroreceptor reflex test‚ with a resting systolic heart rate of 54bpm to a baroreceptor reflex heart rate of 70bpm‚ an increase of 16bpm. 2) Having high blood
