Function of the muscular system— to move the body
Two types of muscles—◦ Voluntary muscles
Muscles you are able to control
◦ Involuntary muscles Muscles you can’t control

Muscular System
Muscles work in a very simple way. All they do is tighten up - that is, contract - and relax.
Muscles can only pull. They never push. The muscular system includes three types of
muscles. They are smooth, which are found on the walls of internal organs, cardiac, which is found only in the heart, and skeletal muscles, which help strengthen the body and connect to bones.

Digestive System--http://glencoe.mcgraw-hill.com/sites/dl/free/007877800x/161752/00050758.html
Digestive system—Function!!Process that breaks down food into small molecules so they can move into the blood
Both mechanical and chemical digestion Mechanical—breaks down food by chewing
and churning Chemical—breaks down food with the help
of enzymes into substances that cells can absorb and use
Digestive system
Food passes through the mouth, esophagus, stomach, small intestine, large intestine, rectum, and out the anus.

Your immune system is a complex groups of defenses that your body has to fight disease.
It is made up of cells, tissues, organs, and body systems that fight bacteria, viruses, harmful chemicals, and cancer cells.
Circulatory system contains white blood cells that engulf and digest foreign organisms and chemicals.

Your respiratory system contains cilia and mucus that trap pathogens. Another term for pathogen is microorganisms
When your immune system recognizes a foreign protein or chemical, it forms antibodies.
An antibody is a protein made by an animal in response to a specific antigen.

The nervous system is the communication system of the body.
It is the first control system of your body using impulses.
The nervous system will respond to a stimulus that is any change inside or outside your body that brings about a response.

A cat jumps when startled by a loud noise. This is an example of an organism sensing and responding to its external environment.
The endocrine system is the system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body.
The endocrine system is the second control system of your body.
Chemicals are the control mechanisms. Endocrine chemicals called hormones are
produced in several ductless glands throughout your body.

This is the human body system produces the hormones that regulate growth

Endocrine System
Function—the system that removes wastes from the body
Organ system eliminates liquid and gaseous wastes from the body?
Kidneys filter blood to remove wastes and keep sodium, water, and other chemicals in balance.
Excretory System

The kidneys are the major organs of the urinary system; they filter wastes from all of the blood in your body.
Parts of the digestive, circulatory, respiratory, and urinary system work together as the excretory system.
Also sweat glands in the skin

The integumentary system is the organ system that protects the body from damage, comprising the skin and hair.
The skin is the largest organ of the body.

Reproduction is the process that continues life on Earth.
Organisms that carry out sexual reproduction form eggs and sperm to transfer genetic information from one generation to the next.
Genes are composed DNA.
Reproductive Sytem
An organism is born with a genetic abnormality not present in any of its ancestors. This abnormality is most likely the result of mutation.
Organs and organ systems begin to develop in humans before birth.
More info.
The sum of all chemical reactions in the human body is known as metabolism.
Cancer is best described as abnormal cell division.

New terms
The interaction of the skeletal and muscular systems to produce locomotion is
coordinated by the nervous system
Circulatory System—transport materials
