Human Organism

Introduction

Organisms maybe defined as "an assembly of molecules that influence each other in such a way that they function as a more or less stable whole and have properties of life". Organisms have so much diversity that even the amount of cells they made up of varies from a single cell to trillions. The set of organs that perform a common function and represent a major organizational level of the human body referred to organic systems. However, there are different views among the authors on this subject, which creates some confusion, as related to the concepts of the system and apparatus, the number of established systems and organs that compose it.

The solution of the problems lies in organizing the content of study of organ systems with a systemic approach and specifies the organs they contain. This will facilitate students to acquire knowledge related to this topic and skill development activities based on logical thinking and the systematization, generalization and integration (Leader, 2008, 21-39).

Discussion and Analysis

In the biological sciences used for system and device names to denote the set of organs that contribute to make an ordinary function common, although there are differences in the meaning of these 2 terms. An organ system consists of homogeneous or similar in their structure and origin, as the predominant structure in the same tissue type originated from a given sheet germination (skeletal, muscular and nervous systems), while a set consists of heterogeneous organs or different in these two aspects (musculoskeletal, digestive, respiratory, urinary, genital, endocrine and circulatory).

System and apparatus are terms used in the biological sciences to denote the set of organs that perform a common function that is different in homogeneous organic system groups and the apparatus, heterogeneous; however, these names use interchangeably, although the trend is to use the word system.

Significance of Human Behavior

Behavioral psychologists have classified human behavior studies as the most important study in the field of behavioral psychology. This is because if the types of traits possessed by Humans that differentiate them from other hominid.

The blueprint: DNA, genes and chromosomes

DNA, also known as deoxyribonucleic acid, is like a computer program. A molecule contains a special code unique to each human being. This code will allow your body to function properly. A cell is like a microscopic plant and very sophisticated. Attention, they are not all identical: not all the same shape or the same function.

For example, intestinal cells can be specialized in the digestion and assimilation of food. Those of the lung can be specializing in fixing the oxygen in the air, and its transfer into the blood cells. The skin cells will form a barrier between the inside and outside the body. There are also neurons, which are brain cells: they produce molecules that will allow communication to send messages to other brain cells.

In fact, DNA can be contained in the chromosome. It consists of a dense network of filaments, coiled about them as a coil. If they can be stretched, there would be a ...
