People can reduce their risk of dengue or other mosquito-borne illnesses by using bug spray, wearing long sleeves and pants and staying in places that have secure window screens and air conditioning, according to the CDC.

True or False?

True

Explanation: spraying of bug spay is measure taken to kill disease carrying insects such as mosquito. mosquitoes may find it very difficult to breathe so therefore their activities are restricted.

Wearing of long sleeve and pant, staying in protected window screen and sleeping in an air conditioned room help to reduce the risk of mosquito-borne diseases. Air conditioning weakens the mosquitoes and make them cold, closing or securing windows helps stop them from biting humans.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
