Male and female condoms and abstinence are birth control methods that protect a person against human immunodeficiency virus (HIV), acquired immune deficiency syndrome (AIDS) and sexually transmitted disease (STD). Preventive measures are being used by different health organizations to prevent the numbers from growing through education and counseling, and studies revealed that the safest way to prevent sexually transmitted infections (STI) is abstinence and followed by practicing safe sex.
According to several data provided by the UNAIDS, ONAP and CDC, an estimated 36.7 million people around the world are living with HIV (and this number is increasingly growing) and more or less 1 million people died from AIDS-related illnesses (with more or less 35 million deaths since the start of the epidemic).
The heart chamber labelled with the “X” mark is called the right ventricle. It is the chamber within our heart that pumps oxygen-depleted blood to the lungs. Although both the right and left ventricle pump blood out from our heart, there are several differences between the two. The left ventricle is responsible for pumping out the blood through our liver, stomach and kidneys while the right ventricle helps the blood flow from our pulmonary artery.
The left ventricle exerts more pressure to pump blood than the right ventricle because it delivers oxygenated blood to different parts of our body while the right ventricle needs only a little effort since it only transports deoxygenated blood that our body does not necessarily need to function properly.
