System have BFS…. IC

Interconnectedness Changes

Page 3: How do the  COMPONENTS  of a  System INTERCONNECT ?

The “BFS”

• Behavior = Role (role of each part)

• Function = Purpose (purpose of the whole system)

• Structure = Parts

BF Behavior vs. FunctionBehavior is specificFunction is general

Page 4: How do the  COMPONENTS  of a  System INTERCONNECT ?

System have BFS…. IC

• Interconnection – there are links between parts

• Changes – If a part fails to perform, it will affect the whole system

molecular components small enough to cross the plasma membrane

Smaller pieces allow for more areas of contact for enzymes and digestive juices to act on speeding up digestion

DigestionDefinition• Digestion is the breaking down of food into

smaller and simpler substances

• Mechanical digestion and Chemical digestion do this in different ways

Chemical Digestion is the breaking down of large complicated molecules into simpler ones by the use of enzymes

OBSERVING DIGESTIVE ORGANS1. External and internal structure of the stomach. a. How would you describe the external appearance of the stomach?

b. What is the action (behavior) of the stomach?

c. How is the stomach designed to perform its function?

2. External and internal structure of the small and large intestines

a. Describe the appearance of the small and large intestines.

b. What are the main actions (behavior) of the small and large intestines?

c. How is the small intestine designed to perform its function?

3. Determining the pH of gastric juice and bile a. Describe the role of gastric juice and bile in digestion.

b. How is the pH of gastric juice and bile related to its role in digestion?

Cone-shaped tongue papillae, seen here in a colored scanning electron micrograph, contain nerve endings that receive and transmit touch sensations to the brain.

As we begin chewing, the tongue shapes food in a ball-shaped bolus for swallowing.

Inside the mouth, shown magnified here, teeth, tongue, and saliva work together to physically and chemically break down food.

Humans produce up to 3 pints (1.4 liters) of saliva daily, and chemical enzymes in the saliva play a major role in disintegrating starchy foods.

This colored scanning micrograph shows a cast of blood vessels from the external wall of the small intestine.

Measuring about 22 feet (6.7 meters) in length, the small intestine performs most of the major digestion and absorption of nutrients.

The walls of the small intestine are lined with millions of projections called villi, which absorb and transmit nutrients into the bloodstream.
