The function of the _____ is to excrete, or remove waste from the body.
excretory system
digestion
____ is the process by which food is broken down into substances that can be used by the cells of the body.
The main purpose of the ___ is to cause movement of the body parts. This system also helps with digestion and circulation. It is made up of over 600 different muscles.
Muscular System
Respiratory System
The parts of the body that are used for breathing make up the respiratory system. This system takes in oxygen for the body, and gets rid of carbon dioxide.
this has several functions - it supports the body, permits movement, protects internal organs, stores minerals, and produces blood cells.
skeletal system
lungs
When the body uses food for energy, carbon dioxide, water, and heat are produced as waste products. Carbon dioxide and water are given off when you exhale from the ______.
In the digestive system, food undergoes two kinds of digestion, ___ digestion occurs as the food is broken into smaller pieces.
mechanical
Voluntary muscles
Are muscles that can be controlled consciously. They move when you think about what you want them to do. For example, muscles the arm and legs can be controlled when walking or running.
Air is inhaled through the nose, where it is filtered, warmed, and moistened.
Nose

What is the total number of adult bones in the human skeleton?
Heat is given off through the largest organ of the body, the ________
skin
chemical
Mechanical digestion prepares the food for ____ digestion, which is the process by which foods are chemically changed into simpler substances
Are muscles, such as heart. That automatically do their jobs without you needing to think about it. These muscles run a the important jobs inside the body, such as breathing and digesting.
Involuntary muscles
Pharynx
Air passes into the pharynx through the nose, which is the area behind the nose that leads to the throat.
these give the basic shape to the body and make up a framework to which muscles are attached. At birth, humans have over 300 bones, but some of them fuse together.
bones
kidneys
As the body breaks down extra proteins, it forms a waste called urea. Salt is also given off as a waste product. Small amounts of urea and salt are released from the skin when you sweat, but most of it is released from the main organs of excretion in the body, the _______.
Digestion begins as soon as food enters the mouth, where the teeth and tongue work together to physically break down the food into smaller pieces. As chewing takes place, a secretion from the _____ softens and lubricates the food.
Salivary Glands
Muscle tissue
Every muscle in the body is made up of a particular kind. There are 3 types
The larynx, or voice box, is located at the bottom of the pharynx.
Larynx
cartilage
Besides bones, the skeleton also contains connective tissue called _____________, which is flexible and tough. This type of rubbery tissue is present in the tip of the nose, the outer ear and wherever two bones meet.
The two kidneys are at the back of the body, just above the hips. They form a liquid called ____,which is made up of wastes and water.
urine
Saliva
This secretion from the salivary glands is called ______.
Muscle tissue that is attached to and moves the skeleton. This type of muscle tissue has stripes and is a voluntary muscle.
Skeletal muscles
Vocal Cords
Vocal cords, which produce the sound of voices, are contained in the larynx.
The places in the skeleton where two or more bones meet are called ________, and these can be grouped into three basic types.
joints
