Body Systems Research

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

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 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

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.

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.
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
