4.1.5. Coronary: Is the circulation of blood in the blood vessels that supply the heart muscle.

5. The Nervous System

5.1. Consist of the brain spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs re responsible for the control of the body and communication among its parts.

5.2. In the human nervous system,sensory nerves carry impulses from the sensory organs of the body back to the central nervous syste out to muscles of the body to cause them to move or act.

5.3. They called neurons a function between two nerve cells, consisting of a minute gap across wich impulses pass by diffusion of a neurotransmitter.

5.4. The eyelash and the eyelids protect the eyes.

8.1.2.4. Obsession with food.

8.1.3. CONSEQUENCES:

8.1.3.1. Alterations associated withthe induction of vomiting or the use of laxatives, wich affect digestive system.

9. The Inmune System

9.1. Bacteri a are microscopic unicellular organism,without nuclei or chlorophyll,that they can appear naked or with a capsule,isolated or in groups and that can have cilia or flagella.

9.2. The most important cells are the white blood cels.

9.3. Vaccines are those preparations, that are administered to people to generated active and lasting immunity against a disease by stimulating the production of defenses.

10. Blood Donation

10.1. You can donate blood in hospitals or in especially equipped coaches.

10.2. The donated blood is kept in sterile bags. It is stored in refrigerators.

10.2.1. Before storing it,the blood is analysed to make sure that it does not have any infections or harmfull substances.

10.3. Transfusions are necessary when a person loses a lot of blood.

11. Animals

11.1. The three most important groups of ivertebrates are:

11.1.1. Worms: There are many different types of worms.They all have very long, soft bodies.

11.1.2. Molluscs: Some molluscs, like snails an calms, have a shell that covers their soft body.

14. The Impact of Plastic

14.1. The first completely synthetic plastic was Bakelite, created from phenol and formaldehyde by the Belgian chemist Hendrik Baekelnd in 1910.

14.2. Plastics not only pollute the coasts, but also affect all marine fauna.

14.2.1. Animals become entagled in them and mistakes the smallest fragments for food.

14.3. Plastics have a high nergy value that can be recovered. They can act as an excellent green fuel, as they have a calorific value similar to natural gas and superior to traditional fuels such as fuel oil and coal.

14.4. Microplastics are small plastics pieces less than five milimeters long wich can be harmful to our ocean and aquatic life.

15. Ecosystems y Plants

15.1. An ecosystem is made up of a specific area and living creatures that live there.

15.1.1. The BIOCENOSIS is the group of living elements in a ecosystem

15.1.2. The BIOTOPE is the group of non-living elements in a ecosystem.

15.2. An ecosystem encompasses biocenosis, that is, the set of living organisms or biotic elements in a given area.

15.3. All plants have three basic parts:

15.3.1. The ROOT anchors the plant to the ground.It allows the plant to get water and other substances that it needs from the soil.

15.3.2. The STEM gives the leaves support. It also carries water from the root to the leaves.

16.3. The organisms that inhabit various marine ecosystems are as diverse as the ecosystems themselves.

17. Enviromrntal Problems

17.1. Problems

17.1.1. 1-Deforestation: the disappearence of forest and rainforests.

17.1.2. 2-Pollution: the accumulation on the gound, in the air and in the water of harmful substances causes pollution.

17.1.3. 3-Desertification: in this transformation of some landscapes into desert areas. The soi is very dry and very poor.Very few living creatures can live in these areas.

17.1.4. 4-Extinction of living creatures: Excessive hunting,fies ,and other actions can cause the extinction or disappearance of living creatures.

17.2. Solutions

17.2.1. 1-Avoid cutting down wild trees for wood. Grow new trees for wood. Substitute wood for other materials.Save and recycle paper.
