Transport System

by Teacher Lisa Chung

​Today's Lesson

​1. Engage by assessing / recalling prior knowledge on transport system.

​2. Explore 2 important of transport system.

​3. Explain 2 types of circulatory systems.

​4. Elaborate about systemic circulation and pulmonary circulation.

5. Evaluate what have you learned today.

​

​Engage :

​Do you know why simple organisms do not need a specialised transport system?

​Explore :

​Explain why a specialised transport system is important to an multicellular complex organism.

Multiple Choice

What is the main organ of the circulatory system?

• bone

• lungs

• heart

Multiple Choice

Which is the following is the correct definition of circulatory system?

• Fights disease so the body stays healthy

• Circulates blood that containing oxygen, nutrients and water throughout the body

• Breaks down food into smaller molecules and absorbs those nutrients into the cells

Multiple Choice

Name the blood vessels that carry blood away from the heart.

• Veins

• Capillaries

• Arteries

Multiple Choice

​Elaborate :

​Explain systemic circulation and pulmonary / pulmocutaneous circulation.

Open Ended

What are the two types of circulatory system?

Multiple Choice

How insects are adapted for an efficient circulation?

• Contraction and relaxation of abdominal muscles help to transport haemolymph

• Contraction and relaxation of heart help to transport haemolymph throughout the haemocoel

• Insect has a long heart to pump haemolymph throughout the haemocoel

Multiple Choice

Name circulation that refers to the blood flow from heart to the lungs and back to the heart again.

• Systemic circulation

• Renal circulation

• Portal circulation

• Pulmonary circulation

Multiple Choice

What is systemic circulation?

• Blood travelling between the heart and lungs.
• Blood travelling to the heart and the rest of the body.
• The vessel that brings blood to the lungs

Open Ended

What is pulmonary circulation?

Open Ended

What is systemic circulation?

​Elaborate :

​Compare and contrast the circulatory systems of frog and human.

Multiple Choice

Which of the following is NOT the similarity of circulatory system in frog and human?

• Both have heart as a pumping organ

• Blood enters heart twice for both frog and human 

• Both have 2 atria and 2 ventricles

Multiple Choice

Which of the following is the correct differences about the circulatory systems of fish and human?

• Fish has an incomplete circulatory system while human has a complete circulatory system

• Blood enters fish heart once but blood enters human's heart twice

• Fish has 3-chambered heart while human has 4-chambered heart

Open Ended

Explain how fish circulatory system differs from frog circulatory system. [2 marks]
