Organization of the body

This is the process of what builds up to an organism and the final step is the organismic level which is all structural promotions working to maintain life.
1. Chemical Level
    a. atoms (tiny blocks of matter) combine to form molecules (water, protein, etc.) they in turn form organelles ( basic stuff of microscopic cells)

2. Cellular Level
     a. They are made up of molecules and enhance to create tissues.

3. Tissue Level (combination similar cells)
    a. groups of small cells have common fuction
         1. Types
              a. Epitheium ( covers bodies surface and lines cavities)
              b. Muscle ( movement)
              c. Connective Tissue ( supports protects organs)
              d. Nervous Tissue ( rapid communication by electrical impulses)

4. Organ Level ( different types of tissue)
   a. at least two types of tissue and complex functions are possible
   b. have specialized functions
                                    
                                                     5. Organ System Level ( work together for common purpose)
                                                        Ex: Respiratory, Muscular, Nervous, or Digestive systems
                                                    
                                                      6. Organismal Level
                                                       a. all structural promotions working to maintain life
The organization of the body is very important because it builds up from atoms all the way to organs and ends in an organism that way life is possible. The systems are key because without the systems working together their is no life because muscles help up move around our world, the nervous helps us respond to our surrounding and respond to body systems.  Digestion helps us breakdown food and give us energy and nutrients to keep going, Excretion helps us to flush out unnecessary things in the body and how the systems help us to reproduce and grow also. I believe that is why the organization is so important because it helps us in life to keep living.

Tissues

1.    Simple Squamous Epithelium

Characteristics of simple squamous epithelial tissue:

This is a single layer of flattened cells with disc-shaped nuclei and sparse cytoplasm. It allows passage of materials by diffusion and filtration where protection isn’t high priority and It also secretes lubricating substances in serosae.

Examples of simple squamous epithelial tissue:

Some examples are Kidney glomeruli, air sacs of lungs, lining of heart, blood vessels, and lymphatic vessels.

2. Simple Cuboidal Epithelium

Characteristics of simple cuboidal epithelial tissue:

It’s a single layer of cubelike cells with large, spherical central nuclei. The function is secretion and absorption.

Examples of simple cuboidal epithelial tissue:

Examples of this are kidney tubules, ducts and secretory portions of small glands, and ovary surface.

3.    Simple Columnar Epithelium

Characteristics of simple columnar epithelial tissue:

This is a single layer of tall cells with round to oval nuclei, some cells have cilia, and may contain goblet cells. The functions are absorption, secretion of mucus, enzymes and more; and probels mucus by ciliary action.

Examples of simple columnar epithelial tissue:

Examples are nonciliated type lines most of digestive things as stomach to anal canal, gallbladder, and excretory ducts; small bronchi, uterine tubes, and some regions of the uterus.

4. Pseudostratified Columnar Epithelium

Characteristics of pseudostratified columnar epithelial tissue:

It’s a single layer of cells of differing heights, some not high enough for the free surface, nuclei at different levels; and may have goblet cells and bear cilia. The functions are secretion, of mostly mucus and propulsion of mucus by ciliary action.

Examples of pseudostratified columnar epithelial tissue:

Examples are nonciliated type in male’s sperm carrying ducts and ducts of large glands; ciliated variety lines the trachea, most of the upper respiratory tract.

5. Stratified Squamous Epithelium

Characteristics of stratified squamous epithelial tissues:

Thick membrane composed of several cell layers; basal cells (cuboidal or columnar), surface cells (flattened). The surface cells have keratin and dead and the basal produce cells of superficial layers. The functions are to protect underlying tissues in areas subjected to abrasion.

Examples of stratified squamous epithelial tissues:

They are found in nonkeratinized forms: the moist linings of the esophagus, mouth and vagina; and keratinized forms the epidermis of the skin and dry membrane.

6. Stratified Cuboidal Epithelium

Characteristics of stratified cuboidal epithelial tissues:

Usually two layers of cuboidal cells. Rare in the body

Examples of stratified cuboidal epithelial tissues:

They are found in the ducts of large glands (sweat glands, mammary glands)

7. Stratified Columnar Epithelium

Characteristics of stratified columnar epithelial tissue:

It occurs at transition areas or between two types of epithelia, and only its apical layer of cells are columnar. Also rare in the body

Examples of stratified columnar epithelial tissue:

They are found in the pharynx, male urethra, and lining some glandular ducts

8. Transitional Epithelium

Characteristics of transitional epithelial tissues:

It resembles both stratified squamous and cuboidal; basal are cuboidal or columnar and surface are dome shaped or squamouslike. Function is it stretches readily and permits distension of urinary organ by contained urine.

Examples of transitional epithelial tissues:

The examples are it lines the ureters, bladder, and part of the urethra

Homeostasis

The clinical definition for homeostasis is a state of body equilibrium or stable internal environment of the body. That is why we always have a reason for shivering and sweating, this is to maintain a healthy and stable body temperature to keep our body functions going.  Without these basic processes we would probably perish and die from overheating and hypothermia and either look like a toasted turkey or a frozen Popsicle.

 The first way and simple way our body keeps cool is by sweating this is a process were the body begins to remove water from the body and tries to keep us cool. Most people believe that sweating is disgusting, like I do because I have excess sweating but it’s a way to not let us over heat because without it we couldn’t withstand the temperature around us. That’s also the reason people need to stay hydrated by drinking water because of the excess water loss throughout the day.

Now the second simple way to maintain our body heat develops when it’s cold outside that is shivering. Now shiver is so awkward especially if are really cold because you shake uncontrollable trying to warm up and sometimes I can even hear my teeth click together. This is because shivering the contracting and relaxing of your skeletal muscle that produces heat from respiration. This may be a simple process but is very important because it does help you produce some energy to keep on going in case you forgot you coat out in the cold air as I sometimes misplace it. 

Thank god these processes help the body maintain the correct temperature to keep going or else we could not even survive could you just imagine us rolling in mud because we couldn’t sweat like pigs or elephants, I sure couldn’t and am glad we don’t have to, aren’t you.
