A. Glass Enamels and Glass Paint are glass surface decorating products. They are also called Vitreous Enamels. They are made to be melted onto the surface of the glass substrate. Their composition is based upon a framework of silica, similar to the glass substrate itself.11: What mediums are used with glass enamels. A: Any glass paint that is applied wet, is wet because it is mixed with a medium. The medium consists of a liquid, or vehicle, and a may contain a binder for adhesion and other substances such as suspending or spreading agents.
The circulatory system of a human compared to that of a frog is different due to the number of chambers each contains. A frogâs heart has three chambers (two atria, and a single ventricle), whereas a humanâs has four (two atria, and two ventricles).The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body.The left atrium receives oxygenated blood from the lungs and skin. Both atria empty into the single ventricle, which is divided into narrow chambers that reduce the mixing of the two bloods.n the systemic circulation, arteries collect the oxygen-rich blood from the heart and transport it to the body tissues. In the process, oxygen from the blood is diffused into the body cells, and carbon dioxide from the cells is diffused in the blood.
Veins from different parts of the body enter the right and left atria. Blood from both atria goes into the ventricle and then is pumped into the arteries, which are blood vessels that carry blood away from the heart. The urinary system consists of the frogâs kidneys, ureters, bladder, and cloaca.
