List of common diseases and their causes pdf are very common vectors of disease. A vector is an organism which spreads disease from one host to another.
Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas’ Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases. Mosquitoes are perhaps the best known invertebrate vector and transmit a wide range of tropical diseases including malaria, dengue fever and yellow fever. Another large group of vectors are flies.
Ticks and lice form another large group of invertebrate vectors. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector. For example, one way of controlling malaria is to control the mosquito vector through the use of mosquito nets, which prevent mosquitoes from coming into contact with humans.

So this means there will be more oxygen carried in the blood. All of this makes the blood pressure go up. The kidney keeps these things constant. If there is too much water, the kidney puts more water in the urine.
If there is not enough water, the kidney uses less water in the urine. There are many types of kidney diseases. A kidney disease makes the kidneys unable to work perfectly but they do work in part. As long as it does not become worse, people may not even know they have it.
The kidneys do not work very much at all. They may need special care from doctors. This sometimes blocks urine flow. It usually causes severe pain. After a time, the stone usually goes out or passes. If it does not go out, doctors may have to remove it. This is a bacterial infection in the kidneys.
It can cause mild or severe kidney failure. This includes people that are born with kidneys in the wrong place, or in the wrong shape. It is most often found in adults. If a person’s kidneys do not work properly, they are very sick. If they have severe kidney failure, they cannot live unless they have a replacement for their kidneys. There are two ways to replace the kidneys: dialysis and transplantation.
There are two kinds of dialysis: hemodialysis and peritoneal dialysis. Every day the person fills the abdomen with fluid. The extra salts, waste, and water that the body does not need goes into the fluid. Then the fluid comes out and takes the wastes with it.
This does part of the job that kidneys do. 4 hours to do this each time. Hemodialysis and peritoneal dialysis are not perfect. They do some of the work of the kidney, but it is not as good as a real kidney. So people who need dialysis are not as healthy. For example, in kidney failure, the kidneys do not make any erythropoetin.
