1.    LIVING THINGS AND VITAL FUNCTIONS

1.1.                What are living things: All living things carry out three processes that are called vital functions

1.1.1.      NUTRITION: Living things obtain the matter and energy taking substances from the environment. Nutrition requires intake of food and oxygen.

1.1.2.     INTERACTION: Consist of perceiving changes on the environment, called stimuli, and reacting to them

1.1.3.     REPRODUCTION: To produce descendents with the same characteristics to ensures the perpetuation of the species

1.2.          Chemical Composition

All living things are made of similar compounds

1.2.1.     Inorganic compounds have simple molecules (Water and minerals)

1.2.2.    Organic compounds are complex molecules made of C,H,O,N,P,S. They are sugars, Lipids, Proteins, Nucleic Acids and Vitamins.

1.3.          Cells

All living things are made of cells. 

1.3.1.     Types of organisms

1.3.1.1. Unicellular organisms. Just one cell or colony

1.3.1.2.   Multicellular organisms: Groups of cells that work together as whole

Cells, tissues, organs, systems.

5.2.                  Digestion

5.2.1.    Is the transformation of food into smaller components to obtain nutrients from it.

8.    ANIMAL NUTRITION: CIRCULATION

8.1.                  Transportation of substances

§         Simple animals interchange substances directly from the outside environment.

§         Other animals have a circulatory system with:

·         Circulating liquid: Blood

·          Vessels (veins, arteries)

·          Pump (heart): Moves the liquid thanks to contraction and dilation movements

La circulación en los vertebrados

*      Circulación sencilla

*      Sólo tiene un circuito y el corazón una aurícula y un ventrículo (Peces)

*      Circulación doble (Resto de vertebrados)

*      Pulmonar: La sangre pobre en oxígeno va a los pulmones para oxigenarse.

*      General: Distribuye la sangre rica en oxígeno desde el corazón a los órganos, suelta el O2 y recoge el CO2
