Fill in the Blanks

The total surface area to volume ratio (TSA/V) of Amoeba sp. is large.

Therefore, Amoeba sp. does not require a

transport system to transport substances in and out of the cell.

Fill in the Blanks

Large complex multicellular organisms cannot obtain essential substances and expel wastes by diffusion because their TSA/V is

Open Ended

Name two types of circulatory system in multicellular organisms.

Fill in the Blanks

In an open circulatory system, haemolymph flows

into the body cavity (haemocoel) and bathes the cells.

Fill in the Blanks

In a closed circulatory system, blood is always contained in a continuous

blood vessel and is distributed to the whole body.

Multiple Select

The circulatory system of insects is an open circulatory system. This

means that one or more hearts pump haemolymph through the blood vessels into the haemocoel.

• TRUE

• FALSE

Fill in the Blanks

Name the tiny openings found at the heart of a grasshopper.

Multiple Select

The fish heart has four chambers.

• TRUE

• FALSE

Multiple Select

In the systemic capillaries of fish, oxygen diffuses into the tissues while carbon dioxide diffuses from the tissue into the capillaries.

• TRUE

• FALSE

Multiple Select

Fish circulatory system is known as

• single circulatory system

• double circulatory system

• Open circulatory system.

• Closed circulatory system.

Multiple Choice

How many chamber does the heart of amphibian has?

• 2

• 3

• 4

Multiple Select

Frog circulatory system is known as

• single circulatory system

• double circulatory system

• Open circulatory system.

• Closed circulatory system.

Fill in the Blanks

Amphibians are said to have an incomplete double circulatory system because the deoxygenated blood and the oxygenated blood are

Multiple Select

Pulmocutaneous circulation in a frog transports deoxygenated blood ........ the lungs and skin and then back to the left atrium.

• to

• from

Multiple Select

There are mixing of oxygenated blood and deoxygenated blood in the ventricle of the frog.

• TRUE

• FALSE

Fill in the Blanks

As there are two different circulations, humans are said to have a

double circulatory system because the deoxygenated blood and the oxygenated blood do not mix.

Fill in the Blanks

In human pulmonary circulation, deoxygenated blood is transported through the pulmonary artery from the

ventricle to the lungs for gaseous exchange.

Multiple Choice

Oxygenated blood from the lungs is returned to the left atrium and flows into the left ventricle and pump out via the

• aorta

• vena cava

• pulmonary vein

• pulmonary artery
