A little quiz on Triple Biology, Paper B.

Resource summary

Question 1

To prevent [blank_start]backflow[blank_end], there are valves in both the heart and the [blank_start]veins[blank_end]. The [blank_start]arteries[blank_end] do not need valves, as the blood inside them flows at such a high [blank_start]pressure[blank_end], they do not need valves. There are three types of valves in the heart: the tricuspid, [blank_start]bicuspid[blank_end] and semi-[blank_start]lunar[blank_end] valves.
  • bicuspid
  • lunar
  • backflow
  • veins
  • arteries
  • pressure

Question 2

On images and drawings of the [blank_start]heart[blank_end], the right and the left side are switched over. This is because you are looking at someone else's heart whilst they are [blank_start]facing[blank_end] you.
  • heart
  • facing

Question 3

This is the cycle of blood from being oxidated at the lungs to returning there for reoxidation: Lungs - gas [blank_start]exchange[blank_end]. 02 blood to left atrium. Through [blank_start]bicuspid[blank_end] valve to the ventricle. Through semi lunar valve to the [blank_start]aorta[blank_end]. 02 blood travels around the [blank_start]body[blank_end]. Looses oxygen to muscles through [blank_start]diffusion[blank_end]. De02 blood to the heart. Through the [blank_start]vena cava[blank_end]. De02 blood to the right [blank_start]atrium[blank_end]. Through [blank_start]tricuspid[blank_end] valve into the right ventricle. Through semi-lunar valve into the [blank_start]pulmonary artery[blank_end]. De02 blood to the lungs to be oxidated.
  • exchange
  • bicuspid
  • aorta
  • body
  • diffusion
  • vena cava
  • atrium
  • tricuspid
  • pulmonary artery

Question 4

Tick all that describe the arteries.
  • Carry blood to the heart.
  • Carry blood away from the heart.
  • High pressure from the small lumen.
  • Tough, thick walls.
  • Muscles have strong, elastic fibres to make them strong.

Question 5

Veins contain valves.
  • True
  • False

Question 6

Capillaries are very [blank_start]small[blank_end]. They have thin, [blank_start]permeable[blank_end] walls that are [blank_start]one cell[blank_end] thick. This is all to speed up the process of [blank_start]diffusion[blank_end] and gas exchange.
  • small
  • permeable
  • one cell
  • diffusion

Question 7

Diffusion and [blank_start]osmosis[blank_end] are both the movement of particles from a [blank_start]high[blank_end] concentration to a [blank_start]low[blank_end] concentration. Osmosis only happens in the movement of [blank_start]water molecules[blank_end]. Both [blank_start]diffusion[blank_end] and osmosis can pass their particles through partially [blank_start]permeable[blank_end] membranes. [blank_start]Active transport[blank_end], on the other hand, is the movement of particles from a low concentration to a high concentration. Active transport requires [blank_start]energy[blank_end]. Plants and certain cells like cells in the [blank_start]gut[blank_end] use active transport to obtain and [blank_start]absorb[blank_end] the [blank_start]nutrients[blank_end] they need. This is because there is often a higher concentration of nutrients [blank_start]inside[blank_end] the cell then [blank_start]outside[blank_end] it.
  • osmosis
  • high
  • low
  • water molecules
  • permeable
  • diffusion
  • Active transport
  • energy
  • gut
  • absorb
  • nutrients
  • inside
  • outside

Question 8

Tick all that apply about the red blood cells.
  • Triconcave shape for a larger surface area.
  • Biconcave shape for a larger surface area.
  • No nucleus to hold more oxygen.
  • Haemoglobin and oxygen react to make haemoglobin oxide.
  • Haemoglobin and oxygen react to make oxyhaemoglobin.

Question 9

There are four components of blood: Plasma, red blood cells, white blood cells and...
  • Bacteria
  • Platelets
  • Ribosomes
