Y3V-T1-LSN4

Circulatory and Respiratory system

Learning Goals LSN3:

• I know what the digestive and urinary systems are and can explain their function.
• I can explain how these organ systems work together.
• I can name identify various organs in each system and explain their functions.
• I can identify differences and similarities between the digestive and urinary systems of humans and other animals.

Explain why having multiple stomachs is functional for a cows digestion system

Learning Goals LSN4:

• I know what the respiratory and circulatory systems are and can explain their function.
• I can explain how these organ systems work together.
• I can name identify various organs in each system and explain their functions.
• I can name and explain the different respiratory & circulatory systems of at least 2 other animals that humans do not have. 

Key words:

• Circulatory system
• Heart
• Ventricles
• Atria 
• Veins
• Arteries
• Capillaries
• Respiratory system

• Nose
• Mouth
• Trachea
• Larynx
• Lungs
• Bronchus
• Bronchioles
• Alveolus 
• Diaphragm

Circulatory System

Responsible for transport of nutrients & gases through the body.

• Double circulation system.
• The optimum connection between the circulatory and respiratory system.

Circulatory System

Respiratory System

Facilitates gas exchange between cells and the environment.

- Respiration

- Ventilation

- Gas exchange

Respiratory system (organs):

1. nose
2. mouth
3. larynx
4. lung
5. bronchi
6. diaphragm
7. pharynx
8. trachea
9. bronchi
10. bronchiole
11. alveoli

Thoracic inhalation:

air is sucked into the lungs

intercostal muscles contract

ribs pull the plearul membrane open

the plearul membrane pulls open the lungs

ribs move up

Thoracic exhalation:

air is pushed out of the lungs

intercostal muscles relax

ribs push the plearul membrane closed

the plearul membrane pushes the lungs closed

ribs move down

Abdominal inhalation:

air is sucked into the lungs

abdominal muscles contract

the diaphragm moves down

the pleural membrane pulls open the lungs

the diaphragm pulls the pleural membrane open

Abdominal exhalation:

air is pushed out of the lungs

abdominal muscles relax

the diaphragm  pushes the pleural membrane closed

the pleural membrane pushes the lungs closed

the diaphragm moves up

Learning goals:

• I know what the respiratory and circulatory systems are and can explain their function.
• I can explain how these organ systems work together.
• I can name identify various organs in each system and explain their functions.

Homework

• Read the following pages in your textbook:p.64-65, 69-72, 80-87.
• Make the assignments LSN4 on classroom and hand them in before the lesson.
• Study the keywords (using Studygo) and check if you manage the learning goals (by repeating lessonup exercises)
