1. Human Body Systems Review
September 2016

2. Directions There will be a total of 4 stations
1. Respiratory System
2. Digestive System
3. Circulatory System
4. Excretory System
You will have 10 minutes at each station to answer the questions
There are various materials at each station to help you
You are to write all your answers in your notebook
Whatever you do not complete at your station in class will be completed for homework

3. Systems of the Body Review

4. Respiratory System
Brings oxygen (O2) into the body and carries Carbon Dioxide (CO2) out of the body
Nose –
Air enters the body (from nostrils to nasal passage)
Mouth –
Air enters the body
Trachea –
The airway through which respiratory air travels. Also called your windpipe
Bronchi –
The trachea divides into 2 main bronchi.
The bronchi extend into the lungs spreading in a tree-like manner as bronchial tubes which then leads to the bronchioles
Lungs –
Transport O2 from the atmosphere into the blood and release CO2 from the blood into the atmosphere

6. Digestive System Breaks down of food and absorption of nutrients
Mouth –
Food is broken down mechanically (chewing) and chemically (saliva)
Esophagus –
Food is carried to the stomach by muscle movement
Stomach –
Food is chemically broken down by acids and digestive juices
Small Intestine –
Nutrients are absorbed into the bodies blood stream

7. Digestive System Large Intestine – Rectum – Anus – Liver –
Water is removed after nutrients have been absorbed
Rectum –
Lower portion of large intestines. Feces are stored here before being excreted (released)
Anus –
Feces are excreted
Liver –
Produces bile which aids in digestion
Gallbladder –
Stores bile and releases the bile into the small intestine
Pancreas –
Produces pancreatic juice (mixture of enzymes) which help bile in the small intestine to break down proteins, starches, and fats

9. When you increase your activity level:
What do the cells need to do?
How will the systems of the body respond/help?

10. Circulatory System
Transports nutrients, hormones, oxygen, water to cells. Removes wastes and carbon dioxide from cells.
Heart –
Pumps blood throughout the body.
Blood vessels –
Network of “highways” (arteries, veins, capillaries) that transport materials.
Blood –
Specialized body fluid that delivers substances to and from the cells.
Lymph Nodes –
A small ball-shaped organ of the immune system. Lymph nodes are found all through the body, and act as filters or traps for foreign particles.

11. Excretory System
Removes all wastes, toxins, and other materials from the body
Kidneys –
Filters our body’s important materials and wastes (such as acids, glucose, water, etc.).
Any excess materials are passed to the bladder as urine
Bladder –
Stores wastes from the kidneys in the form of urine
Urethra –
Tube that connects to the bladder then allows urine to exit the body

13. Wastes are also excreted through the respiratory system, integumentary system, and the digestive system.

14. Other Human Body Systems

15. Skeletal System
Protects and supports the body and organs, works with skeletal muscles, produces red and white blood cells and platelets
Bones –
Structure that makes up the skeletal system
Ligaments –
Stringy connective tissue that holds bone together
Cartilage –
Flexible tissue that gives support and shape to the body parts

17. Muscular System
To move limbs and trunk, to move substances through the body, to provide structure and support
Skeletal Muscles –
Attaches to bone and moves bone
Voluntary Movement – muscles can become tired
Smooth Muscles –
Controls breathing, blood pressure, and digestive movement
Involuntary Movement – muscles do not tire
Cardiac Muscles –
Found in the heart
Involuntary Movement -- muscles do not tire
Muscle Tissues –
Composed of muscle fibers that run beside one another and are held together in bundles or connective tissue
Tendons –
Connective tissue that connects muscle to bone

19. Nervous System
Network of nerve cells and fibers that transmits nerve impulses between parts of the body. Nerves are sort of like wires that carry communication signals or impulses around the body.
The nervous system is itself divided into two sections: 
The Central Nervous System (CNS): Brain and spinal cord.
The Peripheral Nervous System (PNS): sensory receptors and motor effectors.

20. Central Nervous System (CNS)
The complex of nerve tissues that controls the activities of the body.
Peripheral Nervous System (PNS)
Connects the central nervous system to the
parts of the body. It carries messages to
and from the central nervous system.
It sends information to the brain and
carries out orders from the brain.
