1. Integumentary and Excretory Systems
By: Sofia Arce, Fangze Chen, Hailey Garrett, Cindy Lam

2. Standards
SC.6.L.14.5 Identify and investigate the general functions of the of the human body and describe ways these systems interact with each other to maintain homeostasis.

3. Objectives:
Students will identify and/or describe the general functions of the major systems (Integumentary and Excretory) of the human body
Student will identify and/or describe how the systems of the human body interact to maintain homeostasis.
Essential Question:
How do the integumentary and excretory systems work together to allow the body to maintain homeostasis?

4. Vocabulary
Integumentary system- organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside. It includes the skin and its appendages (including hair and nails).
Sweat gland- a small portion of sweat released through the skin
Epidermis- outer layer of cells covering an organism
Dermis-the thick layer of living tissue below the epidermis that forms the true skin

5. Vocabulary Skin- the protective layer of the body
Excretory system- organ system that gets rid of cellular waste from all parts of the body
Kidneys- pair of organs that removes waste from blood
Ureters- tubes that connect kidneys to bladder
Bladder- saclike organ that stores urine
Urethra- a tube where urine exits the bladder

6. integumentary
The integumentary system is the protective outer layer of your body. For example, the skin, hair, and nails.
Very top part of the skin is the epidermis.
Second layer underneath the epidermis is the dermis.
The last layer of the skin is the hypodermis.
The system protects your organs from any
disease in your surroundings

7. integumentary
Dermis- contains the sweat gland, nerves, oil gland, and the hair follicles.
Hypodermis- contains the arteries and veins and fatty tissue.
Sweat Glands- released to cool your body off when the nervous system senses the body temperature is rising
Oil Glands are an oily substance that contain lipids and fat, pimples and acne produce when too much oil is in the skin
Hair also grows from the skin and protects your body, too

8. Excretory System
Helps you get rid of waste and regulates the amount of fluids and salt in the body through a process called urinating
You have 2 kidneys, they remove the waste from your blood
After that the waste or urine travels through 2 tubes each coming from each kidney called the ureters
Urine is stored in a saclike organ called the bladder
Urine then exits the body through the urethra

9. Match each organ to it’s corresponding function.

Dermis
Gets rid of waste
Layer containing sweat and oil glands and hair follicles
Where urine exits the body
Removes waste from blood
The protective layer of the body (skin, hair, nails)
Outer layer of cell covering an organism
Where urine is stored before exiting the body
