Tissue
Tissue is a collection of cells which have similar structure and perform relatively common functions. Common embryonic origin function together to carry out specialized activities.
Simple Squamous Epithilium Tissue
MUCOUSAL TISSUES - These form the walls of the internal vessels of the body. They form the outer surface of the body and the covering of the organs inside it. For example, membrane and skin cells.
It is responsible for releasing different types of fluids in the body.
connective tissue
Supporting tissues like bone CARTILAGE etc
NERVOUS TISSUES
It dissolves the brain and spinal cord. They wake up immediately on the instigation of a stimulus and unsettle the brain. Orders from the brain to different organs are also received through them. There are two types of them.
1 Smooth muscle, the walls of the intestines and blood vessel make.
2 Striated muscles, these are the muscles that attach to the bones and help in the movement of the limbs. They can also be called constitutive muscles.
MUSCLES Of THE BODY
The human body is made up of many different types of tissues and each tissue contains thousands of cells of the same type. A cell is the smallest unit of life in which life activities take place. Every organ of the body performs its work with the help of the body.
So far we have analyzed the human body based on its structure and its functions. This practice gives us two benefits, one is to make our body as a whole.
I got a chance and got to know all the other parts of it. Now let's try to understand in another way, in this way we will compare our body with our house.
If you will get an idea of how a house is made up of many different things. Similarly, our body also has electricity, water, telephone and waste removal systems on many organs. Similarly, the body digests food. Is . Just like the house To do, breathing out unnecessary things? Throwing systems are available. Just as small and large bricks are used to build different parts of a house, in the same way different cells help to form tissues in the body.
From all these things, we can say that the cell, the smallest part of our body, has all the characteristics of life. Many cells of the same type form connective tissue. Then these tissues join together to form the organ. An organ can have the same type of tissue and it can also be made up of different types of tissue. Many organs together form a system. And many other systems. Make the body.
From this we can clearly understand that our body is a complexly arranged unit and understanding its different parts and the functions of each part is a difficult task. If every person is understood as a combination of biological, social and psychological aspects, it must be admitted that we have so far only understood the biological/partial aspect very well. The social and psychological aspects are not yet fully understood.
Let's take a look at the biological aspect as it has been said earlier that our body is based on many systems so it would be better to try to understand each system individually and get more detailed.
Our body is made up of different organs, heart, tongue, lungs, etc.
Examples :Are a human being
Organs: heart, intestines, stomach etc. Humans have the following systems
1. Nervous system
2. . Digestive system
3. Respiratory system
4. Excretion waste system
5. Reproductive system
