ORGANISATION OF HUMAN BODY AND ITS FUNCTION

Generally, the human body is made up of complex structures that coordinate with each other. The human body’s level of organization ranges from the complex physical body parts to the simplest invincible structures known as cells. In many cases, the human body tends to be compared to a machine-like structure. The human body is compared to a machine because their same mode of operations for machine consists of many parts, and each part of it does specifically assigned tasks. Yet, all parts have to work together to produce the overall and the desired output. This is exactly the case with the human body.
Know that the human body that enhances your form of life has tons of tasks to perform to keep the owner alive and operate. It is also important to know that the functioning of the human body operates throughout even if one is at sleep, the body operations keep going. The variety of operation occurring within the human body are super supervised such that there is no interferences or delay. Some operations can be felt, but the owner can’t control them. These are operations like digestion. Other operations are organized that you can’t detect them a bit they keep operating.
The human body is divided into many components based on their functions. The organization of body parts well schemes other cases; some are anatomically scattered all over the body. Let us primarily look at body system organization and its functions on different levels.
Organ system level
Organs coordinate to achieve overall objectives; we have organs like the integumentary system that performs general body covering, thus protecting the inner and sensitive body tissues from physical injuries. It also tends to have other functions like synthesis vitamin D, storage of minerals, muscular system. It will enhance body expressions and movements, also facial expressions. There is also the transportation of metabolic wastes like sweat. This organ also houses some blood capillaries and veins, thus supportive in blood circulation.
five basic organizations of the human body
level one:
CELLS
Cells Are referred to as basic units of this life and are always the first in human body organization. These cells usually have specialized functions; thus, they are usually named according to their functions like liver cells, blood cells, nerve cells, and so on. Thus, it is important to know that these cells are formed from tiny molecules, and for finer details, cells have their structures called organelles, and each organelle in a cell has its defined function. Thus, making the cell capable of producing its desired output.
Level two
TISSUES
A group of different cells with similar functions combine and form a tissue; thus, a tissue usually has certain functions like cells, resulting in different cells working together. For instance, muscle tissue, cardiac tissue, smooth tissue, epithelial tissue, blood tissue, and nerve tissue all have their specific functions.
Level three
ORGANS
From two to several hundreds or son number of tissues are organized to an organ. Which also will have to serve specified functions. Examples of organs include: heart, brain, liver, kidney, and many more, each has a defined role in the human body. The majority of the organs are mostly comprised of four types of tissues. Like the intestine case, epithelial tissue is surrounded by layers of muscle tissue, enhancing several food boluses’ peristaltic movements along the trachea. The intestine is also supplied by connective tissues such as blood tissues whose role is to transport nutrients absorbed by the intestines. There is also nerve tissue presence, which will convey the brain’s message and all instructions.
