  • 3 things that i like: not too many words, good layout and nice diagrams

    2 things that can be improved: diagrams and text can be bigger.

    1 question that i have: what is vein valve?

  • Good colour scheme & layout too, Interesting content. Athough the slide has big word, eg. epithelial cell. Slide 9's words is a little small.

  • 3 things that i like : - The title and the content can be differentiate easily

    - there are diagrams to help in understanding

    -The slides contains a lot of the information

    2 things that can be improved : Try not to squeeze all the words into one slides

    - Try to highlight the important key words with different colours

    1 question: How do artery measures heart beat and blood pressure?

    Marks : 7/10

Transport in humans Transport in humans Presentation Transcript

  • Done by Hong En, Cherie, Putri and Leonard
  • -Blood transports oxygen and nutrients from the lungsand the digestive tract to body cells.-It carries away carbon dioxide and other wasteproducts that the body does not need.
  •  Keeps body at the right temperature Carries hormones to the body’s cells Sends antibodies to fight infection Slides 2-3 made by Hong En Helps blood clotting and heal body tissues View slide
  • THE COMPONENTS OF BLOOD ANDTHEIR FUNCTIONS Plasma Fluid part of blood Carries carbon dioxide, hormones and waste Red blood cells Contain haemoglobin which carries oxygen Made in the bone marrow. White blood cells Produce antibodies and destroy harmful microorganisms Made in the bone marrow Platelets Clump together to form clots to protect the body View slide
  • Blood VesselsThere are three blood vessels. The artery, vein and capillary.Blood vessels are hollow tubes which transfers blood to all parts of the body.
  • Arterythe Artery consists of three lAyers. the outer tissue, the musculAr middle And the inner epitheliAl cell.the Artery cArries blood rich in oxygen to the cApillAries for the exchAnge of oxygen to cArbon dioxide.you cAn use it to meAsure heArt beAts And blood pressure becAuse it expAnds And contrActs.
  • VeinThe vein, similar to the Artery, has three layers. However, the outer layer is thinner.The vein has lesser pressure than the artery, so it is weaker than the artery.The vein contains waste- rich blood as it absorbs gas from the capillaries after the exchange of oxygen to carbon dioxide.The vein contains a vein valve which pushes blood up against gravity.
  • CapillariesUnlike the artery and the vein, the capillaries have only one layer. Which is only one epithelial cell thick. Slides 1, 5-8 and 11 made by LeonardIt exchanges air from oxygen to other waste products.
  • THE STRUCTURE OF ARTERIES, VEINSAND CAPILLARIES THEIR FUNCTIONS Arteries  Carry blood away from the heart (always oxygenated) Have thick muscular walls Have small passageways for blood (internal lumen) (central cavity of a hollow structure in an organism or a cell) Slide 4 and 9 made by Cherie Contain blood under high pressure   Veins Carry blood to the heart (always de-oxygenated) Have thin walls Have larger internal lumen Contain blood under low pressure  Capillaries Found in the muscles and lungs Microscopic – one cell thick Very low blood pressure Gas exchange takes place
