Identify the statement below which is NOT the function of circulatory system.

• Transporting oxygen from the lungs to the cells

• Transporting food from the gut to the cells

• Distributing heat around the body

• Enhancement and facilitation of the immune system

What is the three basic components of circulatory system?

• Lungs

• Blood

• Blood vessels

• Heart

The animals below has an open circulatory system, except for..

• Crabs

• Clams

• Fish

• Grasshopper

When the heart of grasshopper relaxes, it pulls the haemolymph into the heart through pores called..

• Lacunae

• Ostia

• Sinuses

• Capillaries

Which is the correct statement about the difference between open and closed circulatory system?

• Nutrient and gases for open circulatory system must pass through walls of capillaries while closed circulatory system can exchange nutrient and gases directly.

• Blood flow in open in circulatory system is rapid while the blood flow in closed circulatory system is very slow.

• Open circulatory system has no capillary system so tissue are in direct contact with haemolymph while closed circulatory system has capillary system.

• Open circulatory system found in annelids while closed circulatory system found in insects.

What are the three similar layers of structure between vein and artery?

• Endothelium

• Exothelium

• Smooth muscle

• Connective tissue

What type of blood vessels that transport deoxygenated blood from tissue to heart and has very large lumen?

• Arteries

• Capillaries

• Veins

• Ostia

Choose the correct path of blood flow in the circulatory system.

• Artery -> Arteriole -> Capillaries -> Veins -> Venule

• Artery -> Arteriole -> Capillaries -> Venule -> Veins

• Veins -> Venule -> Capillaries -> Arteriole -> Artery

• Artery -> Veins -> Arteriole -> Venule -> Capillaries

• Water

• Other solutes

• Platelets

What is the three main cellular elements in our suspended blood?
