After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.
These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.
This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).
The mass of cells are called blastula.
Lungs are the primary organs of the breathing involved in the process of inhalation and exhalation. Both of these processes require a flexible tissue due to the structural changes during it. This connective tissue of the lungs is called the elastic connective tissue.
Elastic fibres refers to the bundle of protein called the elastin found in the extracellular matrix of the connective tissue proper. They are found in the lungs and its characteristic feature is it can stretch and compress back to its original shape allowing the processes of inhalation and exhalation. It is also called the yellow elastic tissue.
