2. Stem Cells
Stem cells are cells that have potential to develop into many different types of cells in the body. They serve as a repair system for the body.
Two main types of stem cells: embryonic stem cells and adult stem cells.

3. The Body’s Hierarchy

4. Organ Systems Reproductive System Urinary System Nervous System
Muscular System
Respiratory System
Skeletal System
Lymphatic System
Integumentary System
Digestive System
Endocrine System
Cardiovascular System

5. Reproductive System
Production and delivery of sex hormones and transportations of sex cells and development of the fetus
Relationships with other systems:
Reproductive hormones affect brain development
Reproductive hormones affect overall body development
Sexual arousal affects the urinary and respiratory system

6. Urinary System
Basic function is to excrete nitrogenous waste from the body, adjusting the chemical balance of body fluids, and maintaining blood volume
Relationships with other systems:
Affects the skeletal, muscular, nervous, and endocrine system by maintaining chemical balance and secreting hormones
Affects the circulatory system because kidneys affect blood pressure more than any other organ, besides the heart

7. Nervous System
Basic function is to interpret environmental cues and integrate information
Relationships with other systems:
Affects the circulatory system by regulating the heartbeat
Affects the integumentary, skeletal, and muscular system by stimulation
Affects all systems by regulating specific functions within each

8. Muscular System Basic function is to move muscles and generate heat
Relationships with other systems:
Affects the skeletal, respiratory, urinary, digestive, and reproductive system by muscle contraction
Affects the circulatory system because muscle contractions affect the blood flow in the veins
Affects the lymphatic system because exercise elevates levels of immune cells and antibodies

9. Respiratory Systems
Basic function is to exchange the gases between blood and the air
Relationships with other systems:
Respiratory disorders can affect the integumentary, skeletal, and muscular systems
Affects the endocrine and nervous system by maintaining PH balance and producing enzymes
Valsalva maneuver affects the reproductive, digestive, and urinary system by aiding in movement
Affects the circulatory system by returning blood to the veins

10. Skeletal System
Basic function is to support the body, protect organs, and produce blood
Relationships with other systems:
Affects the reproductive, urinary, respiratory, endocrine, and nervous system by protecting vital organs essential to the basic function of the systems
Affects the muscular and integumentary system by providing attachment sites
Affects the circulatory and lymphatic system by producing white and red blood cells from the bone marrow

11. Lymphatic System
Basic function is to produce the cells that make up the immune system
Relationships with other systems:
Affects all other 10 systems by providing various immune cells within all

12. Integumentary System
Basic function is to protect the body, prevent it from drying out, and produce vitamin D through the skin
Relationships with other systems:
Affects the skeletal, muscular, nervous, respiratory, digestive, urinary, and endocrine because it provides calcium needed to perform various functions
Affects the circulatory system by providing a reservoir for blood
Affects the lymphatic system because it can change cells within the skin to alert the immune system
Affects the reproductive system because various glands secrete pheromones and milk via the mammary glands

13. Digestive System
Basic function is to provide nutrients and water to the body
Relationships to other systems:
Affects skeletal, muscular, nervous, endocrine, reproductive, urinary, and circulatory by providing essential vitamins and hormones
Affects the urinary system by complimenting the kidneys in water and electrolyte reabsorption

14. Endocrine System Basic function is to produce hormones
Relationships with other systems:
Affects all other body systems because the hormones produced affect the development and metabolism of most tissues

15. Cardiovascular System
Basic function is to transport oxygen, carbon dioxide, and other materials throughout the body
Relationships with other systems:
Affects all systems by providing a system to deliver vital nutrients

16. Conclusion
Stem cells create the tissues and organs that make up all of the body systems
All the body systems are interrelated
