  1. 1To 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.
    1. Abicuspid
    2. Blunar
    3. Cbackflow
    4. Dveins
    5. Earteries
    6. Fpressure
  2. 2On 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.
    1. Aheart
    2. Bfacing
  3. 3This 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.
    1. Aexchange
    2. Bbicuspid
    3. Caorta
    4. Dbody
    5. Ediffusion
    6. Fvena cava
    7. Gatrium
    8. Htricuspid
    9. Ipulmonary artery
  4. 4Tick all that describe the arteries.
    1. ACarry blood to the heart.
    2. BCarry blood away from the heart.
    3. CHigh pressure from the small lumen.
    4. DTough, thick walls.
    5. EMuscles have strong, elastic fibres to make them strong.
  5. 5Veins contain valves.
    1. ARichtig
    2. BFalsch
  6. 6Capillaries 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.
    1. Asmall
    2. Bpermeable
    3. Cone cell
    4. Ddiffusion
  7. 7Diffusion 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.
    1. Aosmosis
    2. Bhigh
    3. Clow
    4. Dwater molecules
    5. Epermeable
    6. Fdiffusion
    7. GActive transport
    8. Henergy
    9. Igut
    10. Jabsorb
    11. Knutrients
    12. Linside
    13. Moutside
  8. 8Tick all that apply about the red blood cells.
    1. ATriconcave shape for a larger surface area.
    2. BBiconcave shape for a larger surface area.
    3. CNo nucleus to hold more oxygen.
    4. DHaemoglobin and oxygen react to make haemoglobin oxide.
    5. EHaemoglobin and oxygen react to make oxyhaemoglobin.
  9. 9There are four components of blood: Plasma, red blood cells, white blood cells and...
    1. ABacteria
    2. BPlatelets
    3. CRibosomes
