Input:What is the most vital content in this lesson?To reach this lesson’s objective, students need to understand:
The features of the skin.
The frameworks of the skin.
The layers of the skin.
Pathologies that can affect the integumentary system.
How will the learning of this content be facilitated?
The teacher should begin the class by writing the word “Integument” top top the board. The teacher should define to the student “Integument” method “a natural outer covering or coat, such together skin or the membrane enclosing one organ”. In clinical terms, we perform not speak “Skin System” favor we would say “Cardiovascular or worried System”. Instead, medical professionals refer to the “skin system” together the “Integumentary System”.
Next, the teacher should display the video “Integumentary Overview”
(source: https://www.youtube.com/watch?v=8Zj7Uoi3Vxw). The video is only around a minute long and gives a short description of the attributes of the skin and of the great of the skin. After ~ the video, the teacher should start a discussion about what the student’s observed.
The teacher have to hand the end the “Diagram that the Skin” worksheet. If that is possible, task the “Diagram of the Skin” worksheet top top the board using a projector or put right into a PowerPoint paper and project so that the teacher can allude while castle explain. Together the teacher explains, the students have to write the name of each component of the diagram on the line. From this activity, the students will certainly learn around the parts of the skin. That is vital that the teacher describe to the students the the skin is an ext than simply what they view on the outside. The skin has three layers, which will be explained an ext in depth later in the lesson.
Next, the teacher should hand out the “Our Integumentary System” worksheet.
**The college student worksheet does not contain all of this information. Use this as a overview to assist explain the integumentary system more in depth come the students.**
The skin is the body’s biggest organ.
The skin’s features include:
Forming a protective covering
Waterproofing the body
Preventing fluid loss
Blocking the entrance of pathogens into the body
Allowing us to have actually the feeling of touch
Helping to manufacture Vitamin D while screening out harmful ultraviolet radiation indigenous the sun
The skin is made up of 3 layers: Epidermis; Dermis; Hypodermis (Subcutaneous Fat)
Layer 1: Epidermis:
Part of the skin that is visible
New skin cell are developing constantly
When the skin cell are totally formed, they move towards the optimal of the epidermis; this procedure takes 2 weeks to a month
Once the skin cell die, they climb to the optimal of the epidermis. The skin girlfriend see space the dead skin cells.
Dead skin cells are very solid and tough and they protect the body. However, dead skin cells flake off quickly. Every day, abut 30,000 – 40,000 dead skin cells loss off ours body.
95% of the cell in the epidermis room responsible because that making new skin cells.
5% of the cell in the epidermis do melanin—the pigment that gives our skin that is color.
People through darker skin have much more melanin.
Suntans occur when ours body renders extra melanin in solution to sunlight exposure. The melanin help to safeguard us indigenous the sun’s harmful UV (ultraviolet) rays.
Layer 2: Dermis:
Located under the epidermis
Contains nerve endings, blood vessels, oil glands, sweat glands, collagen, and also elastin.
Nerve endings assist us through our sense of touch.
The blood vessels keep the skin cells healthy by sending oxygen and also nutrients, taking away waste.
Oil glands, also called sebaceous glands, produce sebum—your body’s oil.
Sebum help to save skin lubricated, protected, and also waterproof. Without sebum, our skin would absorb water.
Sweat is excreted v the pores in our hands. Our hands acquire sticky as soon as the sebum and also sweat mix—this helps us to grip onto objects.
Layer 3: Hypodermis (Subcutaneous Fat)
Located under the dermis
Made greatly of fat
Helps to save the body warm and absorbs shock.
Also stop skin come the underneath tissues.
The start of hair is discovered in this layer.
Hair grows the end of follicles—which start in this layer and continue to grow through the various other 2 layers.
Hair follicles are uncovered everywhere ~ above the human body except: the lips, palms that the hands, and soles the the feet.
An average head has 100,000 follicles.
Sebum is what gives hair its organic shine.
The skin help you as soon as you space too warm or also cold. Once you get too hot, her sweat glands release body heat and also make girlfriend sweat so that you cool off. When you room too cold, girlfriend blood vessels small so the you save in your body heat.
Pilomotor reflex, or Goosebumps, is led to by the erector chili pulling the hair muscle so the they wake up straight.

Next, the teacher should introduce the student to few of the pathologies the the integumentary system. The teacher have to hand the end the “Pathologies of the Integumentary System.” If that is possible, job the “Pathologies of the Integumentary System” worksheet onto the board using a projector or put into a PowerPoint record and job so that the teacher can allude while they explain. As the teacher explains, the students must write the name of the pathology in the box. Native this activity the students will learn about some of the pathologies that can influence the integumentary system.

**Refer to the teacher’s copy the the worksheet**
Once the worksheet and also information sheet explained, the students will certainly break into groups of three or four. Every student will certainly be provided a “Guess the Pathology” worksheet. On workdesks throughout the room will be images of different skin disorders. The student will job-related together to identify the skin disorder. The students have to use their worksheet top top skin pathologies. Permit the students about 15 minutes to occupational together. Reconvene as soon as 15 minutes is over and review the activity.
The final assessment will certainly be because that the students to answer the question:
Think about what you learned around today in class. What are several of the skin’s functions? our skin is situated on the outside of our body, but is it considered an organ? What great is made mostly of fat? In what layer would you uncover blood vessels, sweat glands, and nerve endings? What class is visible? What happens to our old skin cells?
