GENBIO - Animal Tissue Flashcards
A group of cells with similar structure, functions, and origin working together is called
TISSUES
In animal body, they have been classified based on the type of cell, function, and location in the body
ANIMAL TISSUE
Four Basic Type of Animal Tissue
- EPITHELIAL
- CONNECTIVE
- MUSCLE
- NERVE
This tissue has a free surface.
EPITHELIAL TISSUE
It faces either a body fluid or the outside environment.
EPITHELIAL TISSUE
It provides a covering or a lining for some part of the body.
EPITHELIAL TISSUE
It forms the outer layer of the body and lines internal organs.
EPITHELIAL TISSUE
FUNCTION OF EPITHELIAL TISSUE
- Protective barrier
- Absorption
- Secretion
- Sensation
Skin
EPITHELIAL TISSUE
Lining of the mouth and nose
EPITHELIAL TISSUE
Lining of digestive system
EPITHELIAL TISSUE
In Epithelial Tissue, the cells of the tissue are closely connected to each other via __________.
Cellular Junctions.
Two distinct surfaces of Epithelial Tissue
- Apical Surface
- Basal Surface
It is exposed to the body cavity or exterior.
Apical Surface
MODIFIED TRUE OR FALSE
Basal surface is adjacent to the underlying tissue
TRUE
It is adjacent to the underlying tissue.
Basal surface
Two Types of Epithelial Tissues
- Simple epithelium
- Compound epithelium
Describe Simple squamous epithelium
- Plate like cells
- For exchange of material through diffusion
Capillaries and blood vessels are examples of ___________.
Simple squamous epithelium
This simple epithelial is a shape like dice.
Simple Cuboidal Epithelium
Simple Cuboidal Epithelium is used for _______.
For secretion
It is composed of a single layer of cells and functions as a lining for body cavities, ducts, and tubes.
Simple Epithelium
It consists of two or more cell layers and has protective function as it does in our skin.
Compound Epithelium
It is similar to simple cuboidal epithelium but with added cilia
Simple Cuboidal Ciliated
It lines the terminal bronchioles and respiratory bronchioles
Simple Cuboidal Ciliated
Describe Simple Columnar Epithelium
- Brick-shaped cells
- For secretion and active absorption
It lines the fallopian tube and the endometrium of the uterus.
Simple Columnar Ciliated
It may look stacked because of varying
height.
Pseudo- stratified columnar
