transports nutrients from blood to the cells‚ and it takes back carbon dioxide and other wastes from the cells back into the blood. Despite this difference of function‚ however‚ the lymph and interstitial fluid do interact with each other. Along with pathogens‚ lymph also takes waste from cells to be expelled from the body. Simply put‚ lymph takes away the waste the interstitial fluid is carrying. Interstitial fluid not only interacts with lymph‚ it also interacts with plasma. Plasma is a fluid like lymph

the immune system. White blood cells are located near places where there could be pathogens entering‚ such as the tonsils. They are found in these places because they protect entry into the body. If pathogens do try to enter then the white blood cells will become activated and will attack the area of infection. They become activated when the dendritic cell engulfs neutrophils which contain the remains of pathogens that they have killed. The dendritic cells travel in lymph to the lymph nodes where

PEDROSA MARCH 2013 CHAPTER 1 INTRODUCTION Background of the Study A classic characteristic of human parasitic and bacterial agents is the evolution of routes for transmission pathogens to susceptible hosts. The environment plays a critical role in transmission to humans‚ with many environmental materials serving as vehicles. Microbial contaminants may be transmitted directly‚ through hand-to-hand contact‚ or indirectly‚ via food

Understand roles and responsibilities in the prevention and control of infections. Everyone working in a health and social care setting is responsible for preventing infection. Health and social care practitioners must avoid getting and passing on pathogens‚ such as bacteria and viruses that cause illness. As a health or social care practitioner you should: • Maintain high standards of personal health and hygiene • Be aware of the infection control policies and procedures that are used

Military use of biological weapons “Biological weapons amount to no more than “weapons of mass disruption” (Introduction to Biological Weapons). Biological weapons are toxic materials taken from pathogens (bacteria)‚ host or target. These can be put in something as simple as a letter‚ in an envelope‚ or something as complex as a missile containing the materials inside. The military should not use biological weapons because the U.S. doesn’t have the funds to protect the country‚ they are

but some are and can make us sick. These bacteria are called Pathogens. Pathogens can cause diseases in animals and plants. Some examples of pathogens are leprosy‚ food poisoning‚ pneumonia‚ tetanus‚ and typhoid fever. Fortunately‚ we have antibiotics we can take which help to fight off the bad pathogens. We also have antiseptics to help us keep wounds clean of bacteria and antibiotic soap we use to wash to help keep off bad pathogens. Remember to wash your hands! Are bacteria all bad?

Chapter 16-Lymphatic System & Immunity 1. Explain the functions of the lymphatic system. The lymphatic system functions to balance fluid‚ lipid absorption (via lacteals=lymph capillaries) and defense. It removes toxins/pathogens‚ fight infections and transports excess fluid in the interstitial spaces and returns it to the blood stream. Lacteals absorb digested fats from small intestines and transports it to venous circulation. 2. Trace the general pathway of lymph from the interstitial
