Does the heart work with the skeletal system?
The skeletal system helps protect your heart from severe injures, its "shelters" your heart. Lets say you fall, your axial system will break the fall, without it you would be dead by now. There are 2 types of skeletal systems, the axial, and the appendicular. You can live without the appendicular, but it supports your body, the axial is the most important bones such as: the cranium (skull), your spinal cord, and your ribs. You ABSOLUTELY CANNOT live without the axial system.

Are there diseases associated with homosexuality?
Being a homosexual doesn't cause any disease. STDs are acquired from promiscuous sex, or from a partner who has the disease. Gay men have been shown to be more susceptible to AIDS when they have unprotected anal sex. In areas such as Africa, however, AIDS has become much more prevalent among heterosexuals (who make up a larger percentage of the population).
Gay or straight, diseases are more likely where someone has multiple partners, especially those with unknown sexual histories. In the past, anonymous gay sexual behavior was much more common due to the stigmatization of homosexuality. There are still venues with large numbers of gay men engaged in promiscuous sex, but the majority are related to the use of illicit drugs.
