B3.2 Transport Questionbank

Take blood pressure instead

Use a stethoscope to listen to the lungs

Use a digital heart rate monitor for comparison

Count the number of breaths per minute

Only lignified walls and pits

Only hollow, dead cells and pits

All three features contribute

Pits and lignin reduce transpiration

To absorb oxygen from nearby tissue

To reduce blood pressure for capillaries

To withstand and maintain high pressure from the heart

To slow down red blood cell movement

It allows blood to flow through valves passively

It increases resistance and slows blood flow

It allows skeletal muscles to assist in venous return

It helps blood accumulate before entering capillaries

To restrict blood flow to non-essential organs

To stretch and recoil to maintain consistent pressure

To actively pump blood during diastole

To assist in white blood cell production

Increased lung function

Decreased oxygen supply to cardiac muscle

Increased glucose transport into the brain

Enhanced valve function

In the centre of the stem

On the outer epidermis

Inside the vascular bundle, facing the centre

Between the cortex and phloem

Endothelium lining the lumen

Elastic fibres that stretch and recoil

Valves that open and close

Low friction between blood and vessel wall

Genetic mutation in cardiac troponin

High blood pressure causing arterial damage

High intake of saturated fats

Blockage due to a blood clot
