The work (function) of an organ depends on its structure, but its structure is also adapted to the function performed.

The work (function) of an organ depends on its structure, but its structure is also adapted to the function performed. Let’s make sure of this. To do this, we will divide into two groups. In turn, each group gives examples: the first – the dependence of the work of organs on their structure, and the second – the structure of the organs on the work performed or work.

1. Examples of the dependence of the work of organs on the structure:
* protection of the lungs and heart – chest, consisting of ribs and sternum
* grinding food in the mouth – molars are like millstones
* biting off pieces of food – teeth incisors – like a knife
* movement of limbs – joints
* protection against overheating, water removal – sweat glands of the skin
* softening of blows – fatty layer
2. Examples of the dependence of the structure of organs on the work they perform:
* muscle fibers are long – their contraction provides movement
* intestinal villi (like a sponge) ensure the absorption of substances
* intercostal muscles – contracting and relaxing raise and lower the chest, providing gas exchange – inhalation and exhalation
* form of leukocytes (like amoeba) – capture and destruction of foreign bodies
* contraction of the heart – the movement of blood through the vessels

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
