2.1 Understanding the transport system in human

1. Label the diagram of the heart by using the words given below.

Left ventricle Right ventricle Left atrium Right atrium Pulmonary vein Aorta

Tricuspid valve Pulmonary artery Vena cava Semilunar valves Bicuspid valve

2. Three types of valve in the heart.

Type of valve Function

Tricuspid

Bicuspid

Semilunar

3. Blood vessels are tube in the body that channel blood. Four blood vessels are connected to the heart.

4. Comparison between oxygenated blood and deoxygenated blood

2.2 HUMAN BLOOD

1. Human blood consists of two components:

Oxygenated blood Deoxygenated blood

Difference

Oxygen

Carbon dioxide

The

concentration

of digested

food (like

glucose and

amino acid)

Waste products

Blood vessel that

carries it

Deoxygenated blood has to be carried to the lungs to change it into oxygenated blood

FIGURE 1

The following steps were carried out:Step 1 : Two similar hibiscus plants, about 25 cm tall, were selected.Step 2 : The plants were pulled out of the soil and the roots were washed to remove any remaining soil.Step 3 : The plants were trimmed until ten leaves were left on each plant.Step 4 : Each plant was placed in a measuring jug filled with water, and labelled Fand G, as shown in the figure

above.Step 5 : 10 ml of cooking oil was poured into each jug.Step 6 : A layer of grease was applied to the leaves in G.Step 7 : The plants were placed in the Sun for three hours. The initial and final water levels in both jugs were

recorded in the table below.

Plant F Plant G

Initial water level 75 ml 75ml

Final water level 68 ml 75 ml

Figure 5

The experiment is set up with the following steps.1. Set up the apparatus as shown in diagram 3 (a)2. Weigh the apparatus and record its weight3. Leave the apparatus on a table in a bright room.

4. Repeat step 1 but place the apparatus in a cupboard as shown in diagram6 (b) in the same room.

5. The weights of the plants and the apparatus are taken hourly.

The results of the experiment are shown in table 1
