Understanding cells, fabrics and organs.

  Articles

doctor and first assistance to the aid article Use regularly, the terms that do not always make sense without context or if you are simply not familiar with them. If they do not make sense to a piece, you can completely change how much you understand.

Here to help him with the most basic of all anatomical terms are the fundamental materials of the body building: cells , fabrics , and > Organs . This is the base for the whole body.After doing them, we can go to the system systems or get more specifically, for example, the nervous system .

THE Cells are the smallest unit of life. To understand how the cage looks, take pictures of the chicken egg.It has an external membrane (in the case of an egg, this is a solid peel, but most of the cells are not); It is full of rich nutrients with liquid (white eggs, depending on the cytoplasm in the cell) and has a kernel (egg yolk).

Not all cells are equal. Lacustrine cells are a natural, thin and covered isolation of myelin. Nerve cells perform impulses that are used for communication.Mostly they are a telephone cables of the body, and the details are seen. The Masha cells are thick and elongated, like the vivid rubber strips. The globules are flat and are being repulsed in the form. Cellular forms help them with their individual functions. / P>

Each cell serves a specialized appointment in the body. Muscle cells Contract and nerve cells transmit pulses. The globules are associated with oxygen, while the left globules fight with the infection. / P>

Fabric

, when the cells of a given type are grouped, the resulting structure is called a cloth. There is a muscle tissue, which is made of muscle cell strands.The complex fabric is a layer of fat cells. The connective tissue is a term used for several types of hard and fibrous substances, such as tendons or ligaments.

Most of the time in first aid, we call the tissues more than cells. The cells, as a general rule, microscopic, while the fabric can be seen and manipulated. When you look at the gap to determine if it is you need points , looking for a Zipal wound. Actually, stitches hold the fabric, not separate cells.

When different types of fabrics are organized to perform a complex function, the organ is called. The heart is an organ.It has muscle tissue, connective tissue and nerve tissues that work together for blood pumping.

Organs can do more than one function, and each function can be quite complicated. The eyes feel color, movement and light.They are moving and focused. The largest organ in (or in) the human body is leather.This is an excellent example of layers of fabrics that work together to make several functions:

  • Holds in liquids
  • Adjusts the temperature
  • Heat sensations, itching, pressure,The pain
  • produces hormones

anatomy organization, begins with these three building blocks.Becoming its torn cerebral tissue or the hardness of the bones, is still made of cells connected to each other in the tissue and organized in organs.
