HEALTHY HABITS


1. Healthy Eating Habits

A. INTRODUCTION

A healthy diet is a balanced diet. We need to eat the right amounts of the different food groups. Each food group helps our body in different way. If we do not follow a balanced diet, we feel tired, we can´t concentrate, we don´t feel well and we can have health problems.

As you know, we obtein nutrients from foodNutrients are the substances which plants and animals need in order to live and grow. The digestive system is the group of organs in the body that extract nutrients from food and expel undigested waste. 

B. FOOD  GROUPS

1. Bread and cereals.
2. Fruit and vegetables.
3. Meat, fish, egg and beans.
4. Milk and dairy.
5. Good vegetables oils and fats.

C. FOOD PYRAMID

food pyramid or diet pyramid is a triangular diagram representing the optimal number of servings to be eaten each day from each of the basic FOOD GROUPS. 
It is illustrative and depends on where you live. Our ideal food pyramid is the mediterranean food pyramid.

C. SUGGESTED SERVINGS/PORTIONS FROM EACH FOOD GROUP (*in my opinion):

Cereal and Grains Group: You should eat at least six servings a day.

Fruit and Vegetable Group:  You should eat at least five or six servings a day.

Meat, Fish and Eggs Group:  You should eat about two servings a day.

Good Fats Group:  You should eat in small amounts (30g approx. a day).

Milk and Dairy Group:  You should eat about two servings a day.

Sugary Food and Bad Fats Group: You should not eat (only on party or school birthdays).

D. FOOD GROUPS, NUTRIENTS AND FUNCTIONS


E. HOW MANY CALORIES DO WE NEED A DAY TO BE HEALTHY?

Our bodies need energy to work. A calorie is a unit of energy.
In nutrition, calories refer to the energy people get from the food and drink they consume, and the energy they use in physical activity.
Calories are listed in the nutritional information on all food packaging.

a. Daily requirement
Not everybody needs the same number of calories each day. People have different metabolisms that burn energy at different rates, and some people have more active lifestyles than others.
The recommended intake of calories per day depends on several factors, including:
  • general health
  • physical activity demands
  • sex
  • weight
  • height
So, you should intake about 2.000 kcal / 2700 Kcal per day.

b. Calories and health

The human body needs calories to survive. Without energy, the cells in the body would die, the heart and lungs would stop, and the organs would not be able to carry out the basic processes needed for living. People absorb this energy from food and drink.
If people consumed only the number of calories needed every day, they would probably have healthy lives. Calorie consumption that is too low or too high will eventually lead to health problems.
The number of calories in food tells us how much potential energy they contain. It is not only calories that are important, but also the substance from which the calories are taken.
Below are the calorific values of three main components of food:
  • 1 g of carbohydrates contains 4 kcal
  • 1 g of protein contains 4 kcal
  • 1 g of fat contains 9 kcal

c. Empty calories

Empty calories are those that provide energy but very little nutritional value. 

Sources of empty calories.

The following foods and drinks provide the largest amounts of empty calories:

Solid fats and added sugars: ice creamcookies, cakes,...
Solid fats: ribs, bacon, hot dogs, sausagespizza, ...
Added sugars: fruit drinks, sports drinks, energy drinks,...

Kahoot!

You have been challenged to play a kahoot called "Nervous System (Primary 6)"!

Locomotor system

How we move!

Our body moves in response to signals from the brain. These signals travel through the nervous system to our muscles. These contract and relax to allow us to move, hold objects, kick balls and make other movements. The whole system is called the locomotor or musculoskeletal system. It is made up of the skeleton, joints and muscles.

1. The skeleton
The skeleton´s function is:
- to support and give shape to our body and
- to protect the internal organs.

The skeleton is made up of bones and cartilage. Bones are made of hard bone tissue, but cartilage is made of a more flexible tissue.

There are different types of bones:
a. Short and wide bones, such as our vertebrae, provide support and stability.
b. Flat and thin bones, such as our ribs, protect our internal organs.
c. Long and strong bones, such as bones in our arms and legs, are use for movement.

2. Joints
Our bones are connected at the joints by strong, elastic tissue called ligaments. Flexible cartilage protects the ends of these bones.

There are three types of joints:
a. Fixed joints (for example the skull  that does not move)
b. Semi-flexible joints (vertebrae which allow some movement) 
c. Flexible joints (elbows, wrists, knees, ankles and shoulders which allow a lot of movement).

Unit 1: Interaction

In this unit you will ...
- explore the function and structure of the nervous system.
- investigate the interaction of the nervous system with other systems (locomotor system,...).

0. INTRODUCTION
  
We perceive the world through our senses. Sight, touch, smell, hearing and taste aloow us to explore the environment around us. All the information received by our senses is processed by our most important organ, the brain. The brain is home to the conscious and unconscious mind, as well as our emotions and memory. It controls our involuntary actions, such us breathing or digesting food, as well as our thinking and decision making. What other types of involuntary actions do we have?

SENSORY NEURONS: Collect information from our sense organs (skin, eyes, nose, tongue).

MOTOR NEURONS: Send messages from the brain to our locomotor system.

1.1. What is the Nervous System?

The nervous system is the control center of the body.It is responsible for control and communication of your body. 
The nervous system sends messages from the brain to different parts of the body, such us to respond to the stimuli from our senses. It also controls our internal systems such as the digestive or respiratory systems.



1.2.CENTRAL AND PERIPHERAL NERVOUS SYSTEM
It’s divided into two main systems, the central nervous system and the peripheral nervous system.

A. The central nervous system consists of the brain and  the spinal cord (médula espinal).
           a.1. In the brain we can distinguish three parts:
1.The cerebrum (cerebro)
2.The cerebellum (cerebelo)
3.The brain stem (bulbo raquídeo)

a.2. The spinal cord is located in the back. It controls involuntary movements. It runs down a tunnel of holes in our backbone. The bones, called vertebrae, protect it from damage.

B. The Peripheral nervous system is made up of nerves. The brain communicates with the rest of the body through the spinal cord and the nerves.
Nerves carry information from the organs to the brain and from the brain to the rest of the body. Nerves are made up of tiny cells called neurons or nerve cells, they receive and transmit information. 



*THE CEREBRUM



1.3. REFLEX AND VOLUNTARY MOVEMENTS

We can distinguish two types of movements:
a. Reflex movements (movimientos reflejo): they are involuntary movements in response to external stimuli.
b. Voluntary movements: They are the result of decisions.
