• Welcome Back!
• Please take out your new
packet of notes (Bones,
Muscles and Skin)
• Once you find your new seat
put your card on my front desk.
• Pick up a Body System Text
book by the emergency
window and tell Ms. Mello your
textbook number
BONES, MUSCLES AND SKIN
CHAPTER 1
BODY ORGANIZATION
•The human body is organized by the different components that work together to
perform all of the functions your body does.
•Going from the smallest to the largest, put these terms in order:
_____ Organs
_____ Tissues
_____ Cells
_____ Organ systems
1. The _____________ is the basic unit of structure and function in a living thing.
2. ______________ are a group of similar cells that perform the same function. There are four types:
• _______________________ composed of muscle cells and can contract or shorten
• _______________________ directs and controls electrical messages between the brain and body
• _____________________ provides support for the body and connects all its parts (ex. Bone & fat)
• _____________________ covers the surfaces, inside & out of your body for protection

3. An ____________ is a structure that is composed of different kinds of tissue.
An organ performs a specific job. (ex. Heart, lungs, brain, stomach, skin etc…)
4. An ______________________ is a group of organs that work together to
perform a major function. For example your esophagus, stomach, intestines, and
colon are parts of the Digestive System.

ORGAN SYSTEMS
Digestive- Breaks down food and absorbs nutrients
Nervous- Detects information from the environment and controls body functions.
Skeletal- Supports and protects the body.
Respiratory- Takes in oxygen and eliminates carbon dioxide.
Muscular- Enables movement of the body and internal organs.
Endocrine- Controls many body processes by means of chemicals.
Excretory- Removes wastes.
Circulatory- Transports materials to and from cells.

apple or three twix minis. Which one will provide more
energy?

FOOD & ENERGY
•Nutrients are the substances in the food that provide the
body with everything it needs to carry out all of its
essential processes.
TC
Food provides your body with the needed materials for
growing, repairing tissues and the energy to live.
• There are six groups of nutrients necessary for human health• Carbohydrates• Fats• Proteins• Vitamins• Minerals• Water
FOOD & ENERGY
When nutrients are used the amount
of energy they released are
measured in units called calories.
Calorie- the amount
of energy needed to
raise the temperature
of one gram of water
by one degree
Celsius
Calorie Ted-ed
You need to eat a certain number of Calories a day to meet your body’s energy needs. Your daily energy requirements depends on many factors• Level of physical activity• Age • Gut bacteria• Length of digestive track• Medical conditions• Gender• Metabolism
1. Carbohydrates- Provide short acting energy and the raw materials to
make cell parts
2. Fats- Provide long-lasting energy as well as form part of the cell
membrane and supports your internal organs and insulates your body.
3. Proteins- needed for tissue growth and repair. Also they plan an important role in chemical reactions with cells
4. Vitamins- are helpers in a variety of chemical reactions in the body.
Example Vitamin K helps your blood to clot.
5. Minerals- nutrients that are not made by living things. They are present in soil and are absorbed by plants through their roots… Then we eat the plants.Example calcium is needed for strong teeth and bones.
6. Water- most important nutrient because the body’s vital processes such as the breakdown of nutrients take place in water.
FOOD LABELSBy law every food item must have listed specific nutritional information on it. This information are called food labels.
Food Labels allow you to evaluate a single food as well as to compare the nutritional value of two different foods. There are 4 important parts to a food label.
1. Serving Size- The size of a single serving AND the number of servings in the container.

2. Calories- How much energy you get from one
serving of this food including how many calories
from fat.
3. Percent Daily Value- How the nutritional
content of one serving fits into the recommended
diet for a person following 2,000 calories a day
