Connective tissue

Epithelial tissue

Where are epithelial tissue found?

Located in the nervous system

Mainly present in blood vessels

Covering the body surface, lining organs, and forming glands

Found only in bones

What are the functions of epithelial tissue?

protection from external environments, absorption of nutrients, exchange of materials, and secretion from glands

protection from internal environments absorption of nutrients, exchange of materials and secretion of kidneys

protection from external environments absorption of minerals, exchange of materials and secretion of glands

What are the basic shapes of epithelial tissues ?

Squamous, Cuboidal, Columnar

Rhomboid, Triangular, Circular

What is a squamous shape ?

Round, thick, and smooth

Cuboidal, elongated, and rough

Triangular, wide, and bumpy

Flat, thin, and scale-like

what is a cuboidal shape ?

A cuboidal shape is as tall as they are wide shaped

A cuboidal shape cell is a type of cell that has a triangular shape.

A cuboidal shape cell is a type of cell that has a spherical shape.

what is a columnar shape ?

A columnar shape is taller and narrow, then they are wide

A columnar shape is irregular and asymmetrical.

A columnar shape is a regular and narrow shape, as well as thin

10.

What are connective tissues?

Connective tissues are a type of muscle tissue

Connective tissues are found only in the brain

Connective tissues are responsible for producing hormones

Connective tissues are a group of tissues that provide support and connection between different structures in the body.

11.

12.

What are collagen fibers ?

Collagen fibers are the main structural protein found in the extracellular matrix of connective tissues.

Collagen fibers are responsible for storing energy in the body

Collagen fibers provide strength and flexibility

Collagen fibers are a type of muscle tissue

13.

What are Elastic fibers ?

Elastic fibers are made of collagen and keratin proteins.

Elastic fibers stretch and snap back to original length

Elastic fibers are responsible for bone formation.

Elastic fibers are connective tissue fibers made up of elastin and fibrillin proteins.

14.

What are Reticular fibers ?

Reticular fibers are collagen fibers that form a mesh-like network in various organs.

Reticular fibers are smooth muscle fibers found in the heart.

Reticular fibers are nerve fibers responsible for transmitting pain signals.

Reticular fibers connect connective tissues to adjacent tissues
