1. FOR FUTURE SCIENCISTS
AND DOCTORS
By Andrés Arévalo

2. In this presentation we are going to
introduce the following contents:
- New elements to understand
organism functions
- Serious diseases that affect many
people today

3. NEW ELEMENTS TO
UNDERSTAND ORGANISM
FUNCTIONS:
- Main blood cells (red blood cells,
white blood cells and platelets)
- Cholesterol
- Mitosis

4. Red blood cells

MAIN BLOOD CELLS

5. RED BLOOD
CELLS
They carry oxygen
to all parts of the
body through blood
vessels

6. WHITE BLOOD
CELLS
They protect us
from bacteria,
illnesses,
infections, etc.

7. PLATELETS
When there is an
injury in a blood
vessel, they close
that injury.

8. Platelets act like a gel
that makes a blood
clot.
Blood clot

9. Cholesterol is a substance that we can find in
the blood and in body tissues in vertebrate
animals.

10. Cholesterol is necessary for our body
because the cell membrane is made up of
this substance.
Cell
membrane

11. It is the process in which cells
reproduce by dividing into more cells.
MITOSIS

13. This process
happens all
the time.
Mitosis
produce
identical cells.

14. Mitosis is an example of ASEXUAL
reproduction because only one individual
(cell) is needed.

15. Our nails grow because the
cells divide by mitosis.

16. Our bones grow
because the
cells that make
the bone tissue
divide by
mitosis.

17. SERIOUS DISEASES THAT
AFFECT MANY PEOPLE:
Cancer
Heart diseases
Alzheimer

18. Sometimes the
cell nucleus is
damaged and
damaged cells
grow out of control

20. HEART DISEASES

21. Some of them are
caused by too much
cholesterol. Arteries are
blocked and blood does
not circulate properly.
Blocked artery

22. These foods contain lots of fats and cholesterol.

23. HEART DISEASES

24. ALZHEIMER

25. This disease is caused because many
nerve cells and their connections die.Parts
of the brain do not work properly.

26. So people forget things

27. Emma Yang has invented an
application so that people with
Alzheimer could recognize their
relatives.

28. NEW VOCABULARY
Platelets: plaquetas
Injury: herida, lesión
Blood clot: coágulo
Wound: herida
Damaged cell: célula dañada
To grow out of control: Crecer
descontroladamente
Blocked artery: arteria obstruida

attention!
