So this is the research that my partner and I have gathered. We were assigned a project about animal evolution, and we chose to do the koala. I chose to put this in my portfolio because I really liked doing this project, and I really want to remember it.
I learned so much about the koala family! I especially really enjoyed learning about the hand and feet structure. It's amazing what they look like, and what advantages they have!

To the right is my assignment that was about wolves changing the river. We were given a video to watch, and then had to write about how the wolves changed the environment. They were re-introduced to the National Yellowstone Park and took charge the food chain, and controlled it again too. To learn more, read my report! |

This is my human body book. We learned about every part and system of the human body. We were told to make a book, so this is the online version of my book. Enjoy! :D
Table of Contents
Types of Tissues
The Male Reproductive System
The Female Reproductive System
The Circulatory System
The Digestive System
The Excretory System
The Respiratory System
The Immune System
The Muscular System
The Integumentary System
The Skeletal System
Types of Tissues:
Muscle Tissue- Contracts and shortens so that your body parts can move
Nervous Tissue- Carries electrical signals to the brain, and from the brain
Connective Tissue- Supports and Connects all the body’s parts
Epithelial Tissue- Protects vulnerable/delicate internal lines and organs
The Male Reproductive System:
Main Purpose/Function: Produce sperm that’ll be transported into the woman's uterus via penis
Components:
Penis- External reproductive organ that contains erectile tissue
Testes- Glands that produce sperm and give off testosterone
Scrotum- A pouch of skin that contains the testes and help keep the proper temperature for the sperm production
The Female Reproductive System:
Main Purpose/Function: Transport ova to site of fertilization, where the sperm fertilizes it, and will later become a fetus
Components:
Vagina- Muscular passageway that leads to the outside of the body
Uterus- An organ that functions that receive, retain, and nourish a fertilized egg/growing baby
Ovary/Ova- Houses eggs that will be released each month if not fertilized
Fallopian Tubes- Provides site where fertilization can occur; transfers egg
The Circulatory System:
Main Purpose/Function: Transport the nutrient, water, and oxygen to the billions of cells in your body
Components:
Heart- A muscular organ that pumps blood throughout your body
Blood- A red liquid that travels through your arteries, capillaries, and veins, carrying oxygen and carbon dioxide
Blood Vessel- A structure carrying blood through tissues and organs; vein, capillary, or artery
Red Blood Cells (RBC)- Lack a disc without a nucleus, that transport carbon dioxide to and from tissues
White Blood Cells (WBC)- Protects body against diseases and invaders
Platelets- Helps stop blood from coming out of wounds/cuts by sticking together, and clumping on top of each other
The Digestive System:
Main Purpose/Function: To help break down foods, and gets rid of unnecessary things inside the body through the anus
Component:
Esophagus- The tube that connects your mouth to your stomach
Stomach- A stretchy bag that holds the food after you eat
Small Intestine- Helps digests the food you eat
Large Intestine- Gets waste from small intestine
Gall Bladder- A storage tank for bile that helps your body break down and use fats when necessary
Liver- Filters out toxic wastes in your body
Pancreas- Helps digest the food in your stomach by breaking down sugars
The Excretory System:
Main Purpose/Function: Functions to discharge wastes from body
Components:
Kidneys- Filters blood that contains wastes collected from cells
Bladder- Gathers/collects urine before it gets released
Lungs- An organ that gets oxygen into the blood and removes carbon dioxide from the blood
Ureters- Carries urine to bladder
Urethra- The tube that transfers the urine out of the body
The Respiratory System:
Main Purpose/Function: Functions to supply blood with oxygen so the blood can later be distributed to all the body’s parts
Components:
Trachea- Filters the air that is breathed in, and branches into the bronchi
Bronchi- Air is travelled directly to the lungs via bronchi after it get the air from the trachea
Lungs- This is the main organ of the system, which takes in oxygen, and breathes out carbon dioxide
Diaphragm- Breathing starts from this dome-shaped muscle near the bottom of the lungs. When you breathe in. the diaphragm contracts. When you breathe out, the diaphragm expands.
The Immune System:
Main Purpose/Function: Functions to prevent harmful microorganisms like viruses, bacteria, and fungi out of the body
Components:
Lymph Nodes- Generates cells that functions to fight off microorganisms
Tonsils- Lymphatic cells
Spleen- Acts like a blood filter, which controls the amount of red blood cells, and blood in the body, which also helps fight infections
The Muscular System:
Main Purpose/Function: Functions to allow the body to move
Components:
Skeletal Muscles- Voluntary muscles attached to bones to provide force needed for bones
Smooth Muscles- Located in the walls of internal organs leading from glands
Brain/Spinal Cord- Central nervous system
The Integumentary System:
Main Purpose/Function: Acts as a barrier to protect the body against diseases
Components:
Fingernails/Toenails- Like an envelope, that wraps around the the finger to protect it from microorganisms
Hair- Dead epidermal cells
Skin, (Epidermis and Dermis)- Each is made up with distinct tissues that perform specific functions for the body
The Skeletal System:
Main Purpose/Function: Functions to create a framework so your muscles and organs can connect
Components:
Bones- A type of connective tissue
Skull- The framework surrounding your brain
Rib Cage- Protects the kidneys
Joints- Enables the human body to become mobile
Types of Joints:
Hinge Joint- Enables extensive forward and backward motion
Ball-and-Socket Joint- Enables the greatest range of motion in the shoulder area; allows you to swing your arm freely in a circular rotation
Pivot Joint- Enables the head to move from side to side
Gliding Joint- Enables the body to bend and flex as well as make limited side-to-side motions
