Question

Epithelial tissue has ________ intercellular spaces.
A. Large
B. Small
C. No
D. Both A and B

Answer 1

Hint: Epithelial tissue covers the outsides of organs and blood arteries throughout the body, as well as the insides of cavities in many internal organs. It is a key tissue in glands that performs functions such as filtration, diffusion, and sensory reception.

Complete step by step answer:
Tissue, commonly known as vascular tissue, is densely packed tissue that rests on the foundation membrane with no intercellular gaps. It can be ectodermal, mesodermal, or endodermal in origin and is divided into two categories.
Epithelial tissue is separated into two types depending on cell layers: simple epithelium tissue, which is present in a single layer, and stratified epithelial tissue, which is present in multiple layers.
Squamous epithelium, or flattened cells, cuboidal epithelium, or cubic cell, and columnar epithelium, or columnar cells, are three forms of epithelial tissue depending on cell shape.
The salivary gland, kidney tubules, and ovary surface all have single-layer cuboidal shaped cells that are specialised for secretion and absorption.
As a secretive and protective layer, the multi-layered column-shaped cell tissue can be found in portions of the pharynx, uterus, and vas deferens.
The many varieties of epithelial tissue are determined by the cell layer and shape of the cell:
1. Simple squamous epithelial tissue: Their cells have a scale-like appearance and a flattened or spherical shape. Capillary walls, pericardial, pleural, and peritoneal cavity linings, and alveolar linings of the lungs are examples.
2. Simple cuboidal epithelial tissue: These cells may serve as secretory, absorptive, or excretory cells. Kidney collecting ducts, pancreas, and salivary gland are examples.
3. Simple columnar epithelial tissue: Secretory, absorptive, or excretory cells are all examples of these sorts of cells. Simple glandular columnar epithelium refers to some of these tissues that contain goblet cells. These are present in the stomach, colon, and rectum and exude mucus.
4. Pseudostratified epithelial tissue: They come in two varieties: ciliated and nonciliated. The respiratory epithelium is an example of ciliated tissue.
5. Stratified squamous epithelial tissue: They primarily serve as abrasion and water loss protection. They're mostly found in the mouth, oesophagus, and larynx, among other places. Cuboidal epithelium with a stratified structure
6. Stratified cuboidal epithelial tissue: In nature, their primary job is to protect. They mostly line the sweat gland excretory ducts, which are vast ducts of excretory glands.
7. Stratified columnar epithelial tissue: Secretion and defence are their primary tasks. They can be found in the conjunctiva of the eye's covering.

Therefore, the correct answer is C No.

Note: Histology is the scientific study of tissue. Single-layered flat cells can be found in the kidneys, lungs, heart lining, blood arteries, and other organs, and they aid in the infiltration or diffusion of tiny molecules.
