What is Tissue?
A collection of cells called tissue works as a unit to carry out a certain task for the body. In the human body, there are mainly four primary types of tissue:
- The epithelial tissue: The skin, as well as the lining of the digestive and respiratory tracts, are covered by this tissue. It also aids in enclosing and shielding organs.
- Connective tissue: This tissue supports and connects other tissues and organs in the body. It includes bone, cartilage, and blood.
- Muscle tissue: This tissue is responsible for movement and the generation of force. It includes skeletal, smooth, and cardiac muscles.
- Nervous tissue: This tissue is responsible for transmitting and processing information in the body. It includes neurons and glial cells.
Each type of tissue is made up of specialized cells that are adapted to perform specific functions. Tissues work together to form organs, which perform more complex functions in the body. The tissues and organs of the body are organized into systems, such as the circulatory system, the respiratory system, and the nervous system, which work together to maintain homeostasis and keep the body functioning properly.
There are 4 different tissue types in animals, including:
skeletal muscle (cardiac, skeletal and smooth muscle tissues)
Adhesive tissue (cartilage, blood, bone)
nervous system (neurons and neuroglia)
epithelial cells (simple epithelium, simple cuboidal, simple columnar epithelium, etc.)
Plants have unique tissue types, including:
Skin Tissues (epidermal cells, stomata, trichomes)
discarded tissues (Collenchyma, parenchyma, sclerenchyma)
Vascular organs (Vessel elements, tracheids, companion cells and sieve tubes)
