Nervous System
Matthew H. Josh, Braydon, Lindsay
The brain and
spinal cord are in the nervous system. The brain and spinal cord are the center
of the nervous. The left side of your brain controls the right side of your
body. The majority of the nervous system is tissue made up of two classes of
cells: neurons and neuroglia. The brain is soft and is about 3 pounds. Nerves
are bundles of axons in the peripheral nervous system. The spinal cord is a
long thin mass of bundled neurons that carries information. The nervous system
has 3 main functions: sensory, integration, and motor. The spinal cord is gray. There is two parts of the nervous system. The
neurons or nerve cell is the basic functional unit of the nervous system. If we did not have a nervous system we
could not move
Cardiovascular System
Jenson, Mason
Emma
It transports
blood nutrients gases and hormones. During an average lifespan, the heart beats
3,000,000,000 times. The heart contracts tirelessly more than 2.5 billion
times. There are four parts of the epidermis they are epidermis, dermis, fatty
tissue, and muscle. There are two intestines the large intestines and small
intestines. The heart has many arties and veins. It takes a blood cell just 60
seconds to circulate through your body while at rest. The intestines are 1.5 m.
There are over 2 million red blood cells in the body. The average adult human
brain has up about 100 billion cells. The heart is about the size of a closed
fist. There are about 160,000,000,000 cells in a brain. The lungs can hold up
to 3 to 5 litres of air. The
cardiovascular system is an organ system comprised of the heart, blood and
blood vessel. Without human blood the human body would stop working.
There are about 4.7 to 6.1 million blood cells in the heart. There are about 5 million red Blood cells per
ml of blood.
The Digestive System
Grace Jumah Kiera James
The food travels through the small intestine and the large intestine. The
body gets rid of unnecessary things. Body uses food the Acid breaks
down the food made to break food
down so it’s easier to get rid of. It takes about 7 sec to get from the esophagus to the
stomach. The adult stomach can only 1.5 liters of food when full. The large
intestine is approximately 1.5m.The
digestive system is made up of multiple organs .The food has to travel through a bunch of windy tube .The saliva softer so it’s easier to chew.
The parts it has to
travel through are
Stomach
Small intestine
Large intestine
Appendix( branch that is attached to
the large intestine)
Epiglottis (ufala)
Esophagus (throat
Anus (butt)
Endocrine
System
By Jorja and Matthew.P Tye and Tyler
Endocrine is an important body part. Endocrine glands
release than 20 major hormones directly into the blood stream. The endocrine
system includes all of the glands of the body and the hormones product by those
glands. produce an incorrect amount of hormones. Together with the nervous
system and the immune the endocrine system helps the body to cope with
different events and stresses. The foundations of the endocrine system are the
hormones and glands. As the bodies chemical messenger hormones transfer
information and instructions from one set of cells to another. Although many
different hormones and circulate through the bloodstream, each one effects only
the cells that are genetically programs to receive and respond to its message. Hormone
levels can be influenced by factors such as stress, infection, and changes in
the balance of fluid and minerals in blood.
The Skeletal
System
Emily, Ben, Cody, Moody
The skeletal system includes all of the bones and joints in your body.
Each bone is a complex living organ that is made up of many cells, protein,
fibers and minerals. Skeleton acts like a scaffold by providing support and
protection for soft tissues that make up the rest of the body. New blood cells
are produced by the red bone marrow inside our bones. The skeletal system
provides attachment points for muscles allowing movements at the joints. The
bones in our body act as the body’s warehouse for calcium, iron and energy in
form of fat. Skeletons grow throughout your childhood and provides framework
for the rest of your body to grow along. The skeletal system in an adult’s body
is made up of 80 bones in the following regions: skull, hyoid, auditory
ossicles, ribs, sternum and vertebral column. Bones protect your organs and let
you move in many ways. The bones in your body give your body structure. Adult
skeletons 206 bones in total. The bones in museums are dry, hard and crumbly.
The bones in your body are very much alive. Almost every single bone in your
body is made up of the same material. The outer part of your body is called periosteal.
Muscular
System
Anya , Keely ,Peyton ,Tyson ,Harper
There are more than 600 muscles in your body. They do
everything from pumping blood to helping you lift your heavy backpack. You
control some of your muscles while others like your heart do their jobs without
you. Muscles are all made of the same materials a type of elastic tissue sort
of like the materials in a rubber band. Thousands or even tens of thousands of small
fibers make up each muscle. You have three different types of muscles in your
body: smooth muscles, cardiac muscles and skeletal muscles. Your brain and body
tell your muscles what to do without you even thinking about it. Smooth muscles
are at work all over your body even in your bladder and it also allows you to
hold in your urine (pee). Did you know your heart is a muscle? Your heart is
the most active muscle in your body. Your heart is like a pump or two pumps in
one. Your heart is the size of your fist. There are muscles in your arms, legs,
back and your behind. You will find smooth muscles behind your eyes too. These
muscles keep your eyes focused. These are the types of skeletal muscles found
in your body deltoid, pectorals, biceps, rectus, tendons, and quadriceps.
Respiratory System.
Alison,Marlene,Anastasia ,Heaven.
Your body
could not breathe without the Respiratory system. The Respiratory system is
made up of the Trachea the lungs and the diaphragm. When you breath in air you
bring oxygen into your lungs and blow out carbon dioxide, and also when you
inhale your lungs inflate. The tiny air sacs in your lungs are called Alveoli.
Also there are tiny hairs in your lungs that keep dirt out they are called
cilia. The voice box is known as the larynx. From your lungs blood returns back
into your heart where it is pumped out to the rest of your body, carrying
oxygen with it
