Name different types of connective tissues and their functions and the constituents of each connective tissue
Answers
Answer: 1. Different types of connective tissues include areolar tissue, adipose tissue (fat), blood, bone, and cartilage.
Areolar Connective Tissue:
It is found underneath the skin; also around nerves and blood vessels.
It is composed of fibroblasts, macrophages and mast cells.
It provides support and repair tissues.
Adipose Tissue:
It is present in skin and organs.
It is composed of fat globules and is characterized by fat storage
It provides insulation due to the fat present.
Areolar tissue and adipose tissue are two types of loose connective tissues where the cells and fibers are loosely scattered in the semi-fluid matrix.
Bone:
Bone is a hard connective tissue which forms the framework of the body.
It has a rigid matrix rich in calcium and collagen fibers.
Functions include protection, support, facilitates movements and serves as a site for blood cell production.
Cartilage:
Cartilage is made of chondrocytes with dense, flexible intercellular materials.
In the majority of vertebrates, cartilages in embryos get replaced by bones on maturity.
They are present at the tips of external ears, bronchi, vertebral column, etc.
Blood:
Blood is the only fluid connective tissue composed of blood cells (RBC, WBC, and platelets) and plasma.
Functions: Transportation , blood clotting and helps in homeostasis.
Blood, bone, and cartilage are specialized connective tissues.
2. Connective tissue has three main components: cells, fibers, and ground substance.
