Answer:

Endocardium

Explanation:

The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.

The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell

Dennis_Churaev [7]

Answer:

The objective itself is usually a cylinder containing one or more lenses that are typically made of glass; its function is to collect light from the sample.

A telescope mirror can be made from glass that is somewhat less pure than that used to make a lens, since light does not pass through it.
