3. Review
What are the three organs out side the body that make up the integumentary system?
What are the three main parts of the nervous system?
What tissue system in plants carries the phood food/sugar/sucrose from the leaves down to the roots?

4. Learning Objective
I will be able to identify and describe the functions of the organs belonging to the digestive and excretory systems.

5. Language Objective
Excretory and digestion system groups will present their slides. We will go through other slides in depth, and complete the FRAME, and watch a brief video on how the heart functions.

6. Guiding Questions?
The excretory system filters waste from the blood and makes urine – what system works with the excretory system to filter the blood?
The digestive system breaks down food physically, and then chemically into energy rich molecules that the rest of the body use as fuel – what system do you think delivers the food through the rest of the body?

7. Organ System Presentations Raise your hand if you have a question.
Conversation
No talking. No whispering. Respectfully say “shh”.
Help
Raise your hand if you have a question.
Activity
Each digestive group will present their slides.
I will show my slide and review key points.
I will popsicle stick questions for the system
Repeat with excretory system group
Movement
Remain seated. No bathroom breaks.
Participation
Sit up, pen/pencil in hand with your FRAME out.

8. DIGESTIVE SYSTEM PRESENT

9. Digestive System

10. Functions of the Digestive System
Ingestion = Food
enters the mouth.

11. Functions of the Digestive System
Ingestion = Food enters the
mouth.
Digestion =
Process that breaks
food down into
small molecules

12. Functions of the Digestive System
Ingestion = Food enters the
mouth.
Digestion = Process that
breaks food down into small
molecules
Mechanical digestion =
Food is chewed and
churned.
Chemical digestion =
Breaks down large food
molecules into smaller
molecules to be
absorbed by cells

13. Functions of the Digestive System
Ingestion = Food enters the
mouth.
Digestion = Process that
breaks food down into small
molecules
Absorption =
Small molecules of
food are taken into
the body cells.

14. Functions of the Digestive System
Ingestion = Food enters the
mouth.
Digestion = Process that
breaks food down into small
molecules
Absorption = Small
molecules of food are taken
into the body cells.
Elimination =
Wastes made of
unabsorbed food
molecules pass out of the body.
Large Intestine

15. Which is not a function of the digestive system?
Breaking down food into molecules the body can use
Absorbing food molecules into the blood to deliver to the body
Changing waste into molecules the body can use
Eliminating undigested waste from the body

16. Organs of the Digestive Tract
Mouth = Digestion starts here.
The tongue & teeth mechanically break food up.

17. Organs of the Digestive Tract
Mouth = Digestion starts here.
The tongue & teeth mechanically break food up.
Saliva chemically digests food.
Saliva = Mostly made of
water, also contains mucus
and enzymes

18. Organs of the Digestive Tract
Mouth = Digestion starts here.
The tongue & teeth mechanically break food up.
Saliva chemically digests food.
Saliva = Mostly made of
water, also contains
mucus and ptyalin (an
enzyme)
When swallowing, the epiglottis
(a small flap of tissue) automatically closes over the trachea (windpipe).

19. Organs of the Digestive Tract
Esophagus
Smooth muscles force food into the mucus-lined esophagus.
Rhythmic muscular
contractions
(peristalsis) push food
downward.

20. Organs of the Digestive Tract
Stomach
Food undergoes mechanical digestion when stomach muscles churn the food.
Chemical digestion
happens when hydrochloric
acid (HCl) and pepsin
break down the complex
proteins.
Peristalsis pushes the food
toward stomach’s exit.

21. Organs of the Digestive Tract
Small Intestine (6 meters long)
Most digestion happens here.
Intestinal juice
(full of enzymes)
breaks down food.

22. Organs of the Digestive Tract
Digestive Helpers
Liver = Bile is
produced here (Bile
breaks up fats like
dish detergent
breaks up grease.).
Gall bladder = Bile
is stored here until
released into the small intestine.
Pancreas = Produces
pancreatic juices that
are released into the small intestine to break down proteins, starches, and fats

23. Where does most digestion take place?
Mouth
Stomach
Small intestine
Liver

24. Organs of the Digestive Tract
Large Intestine (1.5 meters long)
Undigested food spends 18–24 hours here, and most of the water is absorbed.

25. Organs of the Digestive Tract
Large Intestine (1.5 meters long)
Undigested food spends 18–24 hours here, and most of the water is absorbed.
Helpful bacteria
living in the large
intestine make
vitamins K and B.

26. Organs of the Digestive Tract
Large Intestine (1.5 meters long)
Undigested food spends 18–24 hours here, and most of the water is absorbed.
Helpful bacteria living in the
large intestine make vitamins
K and B.
Materials not
absorbed form into
solid waste (dead
bacteria, some fat and
protein, undigested
food, dried out parts of
digestive juices, and old intestinal cells).

27. Organs of the Digestive Tract
Large Intestine (1.5 meters long)
Undigested food spends 18–24 hours here, and most of the water is absorbed.
Helpful bacteria living in the large
intestine make vitamins K and B.
Materials not absorbed form into
solid waste (dead bacteria,
some fat & protein, undigested
food, dried out parts of digestive
juices, and old intestinal cells).
Solid waste passes
into the rectum and is stored until it is eliminated from the body through the anus.

28. The Digestive System
Purpose: to breakdown food to provide energy and nutrients
* mechanical and chemical digestion
Major Organs and their Functions:
Mouth – to chew and grind up food – includes salivary glands, tongue, teeth
Esophagus – pipe connecting mouth to stomach
Stomach – secretes strong acid (pH = 2) that leads to breakdown of food
Small Intestine – where broken down food is absorbed into the bloodstream
Large Intestine – removes water from the liquid waste and gets the waste ready for excretion
Liver – produces bile, which breaks down fats in foods
Gallbladder – pouch-like organ that stores bile
Pancreas – produces the hormone insulin that regulates blood sugar levels

30. EXCRETORY SYSTEM PRESENT

31. Excretory System

32. Excretory System Why do our bodies need to filter waste from the body?
Maintain homeostasis
Removal of harmful materials
Removal of excess fluids, chemicals, minerals, vitamins, salts, and other wastes from the blood

33. Organs of the Excretory System
Kidneys = filter
blood that has
collected wastes
from cells

34. Organs of the Excretory System
Ureters = tubes that
lead from each kidney to bladder

35. Organs of the Excretory System
Urinary bladder =
muscular organ that
holds urine

36. Organs of the Excretory System
Urethra = tube that carries urine from the bladder out of the
body

37. Where is urine stored until the body is ready to eliminate it?
Kidneys
Ureters
Bladder
Urethra

38. Functions of Excretory System
Rids blood of
wastes (urea)
Controls blood
volume by removing
extra water
produced by cells
Balances salts and
water so cells can function properly

39. Which is not a function of the excretory system?
Removes wastes from the blood
Removes excess water from the blood
Removes carbon dioxide from the blood
Removes excess salt from the blood

40. Purpose: removal of body waste
The Excretory System
Purpose: removal of body waste
Major Organs and Their Functions
Kidneys – the main organs of the excretory system
-- blood full of waste enters the kidney and the kidney filters out urea, excess water, and other waste products, which eventually travel out of the kidney as urine
Urinary Bladder – the body’s urine storage tank
