Exercise 4. Read and translate the text:

A large number of cells make up our body. They range from small cells, some of which have a short life span, to others which are extremely large and which may survive in the body as long as we remain alive.

Structurally, each of the cells is divided into two main parts, the nucleus and the cytoplasm.

The nucleus is a large, spherical structure: it is surrounded by cytoplasm. It is a most important structure for several reasons. It is important because it is present in all mammalian cells except red blood cells and keratinized cells. Very frequently nuclei serve as the basis for diagnosing a pathologic process. Aside from their staining characteristics, which make them useful to histologists, nuclei are important biologically.

A double membrane, the nuclear membrane, separates the nucleus from the cytoplasm. The cytoplasm has been shown through electron microscopy to contain many well-organized structures, called organelles and inclusions. The inclusions contain food and secretory and pigment granules.

The cell membrane is the thin membrane which surrounds the cytoplasm. The cellular membrane contains lipid and protein molecules. The membrane also contains tiny holes, called pores. The cellular membrane prevents leakage of the inner cellular structures into the surrounding environment. Serving as a highly selective barrier, the membrane keeps certain unwanted substances from entering the cell but admits other substances that are necessary for maintaining cellular life.

Pinocytosis is the process of absorption of liquids through a cellular membrane. Phagocytosis refers to the process of ingestion or moving of solids through the cell membrane. Phagocytosis is a mechanism of defense against bacteria, or other harmful substances, since these substances are ingested by the cells that combat inflammation.
