Transcript of In the integumentary system there are four different tissue

Epithelial Tissue
Functions
Epithelial Tissue
Epithelial tissue is the skin you see when you look at a person, it covers the entire outside of the body plus some inside areas like blood vessels, covering inside and the outside of organs.Epitheal tissue is avascular, meaning it gets no blood flow.
Connective Tissue
Connective tissue is the most common tissue in the body and it includes adipose,skin, bones, cartilage, blood, and tendons and ligaments. It surrounds and is found between organs.
Connective Tissue
Functions
Tendons connect muscle to bone and ligaments connect bone to bone or holds a joint together
Loose connective tissue like adipose is a fatty cell that insulates the body
Bone is the hardest and strongest tissue and it provides the body's structure and protection
Blood transports oxygen and nutrients throughout the body
Muscular Tissue
There are four types of muscular tissue skeletal, cardiac,smooth and sphincter. Its located around the bones, in the heart, and on walls of hollow organs.
In the integumentary system there are four main tissue types, those are Epithelial, Connective, Nervous and Muscular tissue in this presentation you will learn about the different types of tissue and how they function.
Different Tissue Types
Muscular Tissue
Functions
Nervous Tissue
Nervous Tissue
Functions
The skin is made of Epithelial tissue and it is our first line of protection against infectious bacteria and viruses.
In the digestive tract epithelial tissue absorbs in nutrients, as well as the skin
Epithelial tissue functions in secretion by allowing the body to sweat
Sensory perception occurs in areas like our lips and fingertips
Skeletal muscles are voluntary and provide body movement
Cardiac muscles are involuntary heart muscles that keep the heart going and blood pumping through the body
Blood vessel and organ walls are made of smooth muscle
Nervous tissue is located in the brain, spinal cord and in nerves. It is the main component of the nervous system.
Nervous tissue produces and transmits nerve impulses to and from body organs to the neuron. Cells called neuroglia insulate and protect the neuron.
Breaking down the integumentary system
Epithelial Tissue
Cardiac Muscle
Muscle tissue
Simple Cuboidal is only once cell thick and it lines ducts & the kidneys. It being only one cell thick allows it to function in aborption and transportation of substances filtered out by the kidneys.
This is a diagram of simple cuboidal tissue
The area that the arrows are
pointing to is simple cubodial tisseu lining a convoluted tube of the kidney
Connective tissue
Dense regular Connective tissue is collagen fibers that are tightly packed and lay parallel. Tissue like this is found in tendons and ligaments
Collagen fibers are what provide the tissue its stretch. Elastin fibers are much thinner than collagen and they allow the tissue to stretch to 150% its begining length. Fibroblast cells are there to repair and produce collagen and elastin fibers.
This diagram shows how the fibers are arranged in parrallel
Cardiac Muscles are only found in the heart and are made of fibers. The muscle cells branch out to three or four others connecting themselves to eachother.
In this picture you can see how the fibers wrap around and connect to eachother
If you can't see it in the first picture this diagram has it labled where the cardiac fibers meet and connect at
Nervous Tissue
Neurons are specialized cells. Dendrites receive messages from other neurons, the message is then moved through the axon to its end and to the synapse. Myelin sheaths cover the axon as insulation to keep the eletrical impules inside the cell.
In this picture you can see the main structure of neurons.
If you cant understand what you're looking at in the first picture this diagram better breaks down the anatomy of a neuron
I think that muscle tissue is the best fit tissue type for its location and function because it is located all over the body and has so many differnt functions. Muscle tissue allows us to move, to breath, moves food and waste through the body, and pumps our blood.
