Tissues

what are the four major muscles in the body?

connective tissue

muscle tissue

nerve tissue

epithelial tissue

what is the general function of these four major tissues?

connective tissue = function is for support, protection of external pathogens, and used as a defence

muscle tissues = function is for movement, stabilisation, protracts organs.

nerve tissue = function is for communication and control of body functions.

epithelial tissue = function is for protection, absorption, and secretion.

How many different types of epithelial tissue consist of?

6 types of epithelial tissue

what are the functions and locations of the simple squamous epithelium tissue?

Simple squamous epithelium is a single layered flattened cell functions in absorption and secretion and is located in alveoli of the lungs, lining blood vessels, and serous membranes.

what are the functions and locations of the simple cuboidal epithelium tissue?

Simple cuboidal epithelium is cube shaped cells

that functions in secretion and absorption and is found in the kidney tubules, glands, and the surface of the ovaries.

what are the functions and locations of the simple columnar epithelium tissue?

Simple columnar epithelium functions in absorption and secretion, and is found in the lining of the stomach, intestines, and uterus.

what are the functions and locations of the stratified squamous epithelium?

Stratified squamous epithelium functions to protect underlying tissues from abrasion and is located in the skin, linings of the mouth, throat, esophagus, and vagina.

what is the function and locations of the pseudostratified Ciliated columnar tissue?

Pseudostratified columnar epithelium functions in secretion and movement of mucus with cilia , and is found in the respiratory tract and the linings of the trachea and bronchi.

what is the function and location of the transitional epithelium tissue?

Transitional epithelium functions to allow stretching and is found in the lining of the urinary bladder, ureters, and part of the urethra.

what are the three types of Muscle tissue?

there are Smooth muscle

cardiac muscle

skeletal muscle

what are the functions and locations of the skeletal muscle tissue?

Skeletal muscle tissue are long cells

that functions in voluntary movement of the body and is attached to bones. It is also involved in posture and generates heat.

what are the functions and locations of smooth muscle tissue?

Smooth muscle tissue consists of spindle-shaped (or short) cells that function involuntarily to control movements within hollow organs, such as the digestive tract, blood vessels, and uterus.

there a three main types of muscle tissue, what are these called?

proper

fluid

supporting

what are the function and location of the proper connective tissue?

Proper connective tissue includes dense (tendons and ligaments) and loose (like areolar, adipose, and reticular) connective tissues that support, bind, and protect organs and tissues. It can be found throughout the body, providing structural integrity and elasticity.

what are the function and location of the fluid connective tissue?

Fluid connective tissue functions to transport substances throughout the body and is primarily found in the blood and lymph.

what are the function and location of the supporting connective tissue?

Supporting connective tissue provides structure and support to the body, primarily found in cartilage and bone.

what is the function and location of areolar tissue (loose proper connective)

function is to provide support, elasticity

It is found beneath the skin, surrounding organs, and in mucous membranes.

what is the function and location of adipose tissue (loose proper connective)

it is a cell that stores fat , which functions as insulation and padding.

It is found under the skin and round organs

what is the function and location of the reticular tissue (loose proper connective)

Reticular tissue provides a supportive framework for organs, particularly in lymphatic and hematopoietic systems.

It is primarily found in the liver, spleen, lymph nodes, and bone marrow.

what is the function and location of the regular dense ( proper connective)

Dense regular connective tissue provides strength and resistance to tensile forces. It is primarily found in tendons and ligaments.

what is the function and location of the regular dense ( proper connective)

This tissue supports structures under tension, located in tendons, connecting muscles to bones, and ligaments, connecting bones to other bones.

what is the function and location of the irregular dense (proper connective)

Irregular dense connective tissue provides strength and resistance to multidirectional forces. It is primarily found in the dermis of the skin,

what is the function and location of the fluid connective tissue blood?

they are found inside blood vessels and they’re function is to transport, heal, and defence

what is the function and location of the fluid connective tissue lymph?

Lymph is found in lymphatic vessels and plays a crucial role in the immune system by transporting lymphocytes and draining excess interstitial fluid.

what are the three supporting connective tissues?

Elastic

Hyaline

Fibro

what is the function and location of the supporting connective tissue Elastic?

it is found in places like the ear and aorta, there function is to create flexibility and support whilst being able to retain their original shape

what is the function and location of the supporting connective tissue hyaline?

they are found mainly at the end of bones,joints, and in the respiratory tract, providing support and cushioning while allowing for smooth movement.

what is the function and location of the fluid connective tissue Bone?

Bone is found throughout the body, which is used for hard support, and storage for minerals and cells
