Answer

Any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.

Answer

In an organism's body
All Cell's together form a tissue
All tissues form into an organ

Organ system - organism

Answer

Tissue:

Tissue is a group of cells that work together to perform a specific function in the body. It is a fundamental unit of life and is found in all multicellular organisms. There are four main types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

Epithelial Tissue:

- Epithelial tissue covers the surface of the body and lines the internal organs and cavities.
- It protects the underlying tissues from injury, infection, and dehydration.
- It also helps in absorption, secretion, and sensory perception.
- Epithelial tissues are classified into various types based on their shape and arrangement, such as squamous, cuboidal, and columnar.

Connective Tissue:

- Connective tissue provides support, structure, and protection to the body.
- It connects and holds the different organs and tissues together.
- It also plays a role in transportation, storing energy, and defending against foreign substances.
- Examples of connective tissue include bone, cartilage, adipose tissue, blood, and fibrous tissue.

Muscle Tissue:

- Muscle tissue is responsible for movement in the body.
- It is composed of specialized cells called muscle fibers that contract and relax to produce force and motion.
- There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle.
- Skeletal muscle is attached to the bones and helps in voluntary movements.
- Cardiac muscle is found in the heart and is responsible for its rhythmic contractions.
- Smooth muscle is found in the walls of organs, blood vessels, and glands and helps in involuntary movements.

Nervous Tissue:

- Nervous tissue is responsible for transmitting and processing information in the body.
- It consists of specialized cells called neurons that communicate with each other through electrical and chemical signals.
- Nervous tissue forms the brain, spinal cord, and nerves.
- It helps in sensory perception, motor control, and coordination of bodily functions.

In conclusion, tissues are groups of cells that work together to perform specific functions. The four main types of tissues in the human body are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Each type of tissue has its unique structure and function, contributing to the overall functioning of the body.
