The Human Cell

Cells are the basic building blocks of living things and they provide structure for the body, take in nutrients from food, and convert those nutrients into energy. Cells can make copies of themselves and they contain the body’s hereditary material.

Cells group together to form tissues; tissues group together to form organs like the kidney and brain; organs group together to form systems like the digestive and respiratory systems; the systems make up the human body.

Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell such as processing chemicals, generating energy for the cell, and making proteins. Just as the human body has its systems, the cell has its systems such as the digestive, respiratory, and excretory systems.

The human cell has a number of major parts which include:

  1. Cytoskeleton: The cytoskeleton is a network of long fibers that make up the cell’s structural framework. It has several significant functions including determining cell shape, participating in cell division, and allowing cells to move. It also provides a track-like system that directs the movement of organelles and other substances within cells.
  2. Ribosomes: These are organelles that process the cell’s genetic instructions to create proteins.
  3. Nucleus: The nucleus serves as the cell’s command centre, sending directions to the cell to grow, mature, divide, or die. It houses DNA (deoxyribonucleic acid), the cell’s hereditary material. The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA and separates the nucleus from the rest of the cell. The genome (an organism’s complete set of genetic instructions) is found in the nucleus.
  4. Mitochondria: These are complex organelles that convert energy from food into a form that the cell can use. They have their own genetic material separate from the DNA in the nucleus and can make copies of themselves.

The body consists of trillions of cells and these cells require constant nourishment for rebuilding. Rebuilding and replacement of cells are constantly taking place. When you fail to provide the cells what they need and the cells are not cleansed of toxic materials, weaker cells end up replacing strong cells. If this goes on progressively, it can lead to illness and ultimately, an untimely death.

People are quick to attribute illness to old age, heredity, and “the will of God.” Failing to provide the cells of the body with adequate and proper nutrition does lead to sickness. What is crucial for the replenishment of cells so that new cells are as strong or stronger than those they are replacing? Proper and adequate nutrition. Know this: With your diet and lifestyle you can pollute your body so much that your cells drown in pollutants.

If your cells are healthy, your entire body will be healthy.
