Circulatory system

QuestionAnswer
Circulatory system the organ system repsonnsible for transporting substances around the body Function: transporting Composed of heart blood blood vessel lymph lypmh vessels
Blood the connective tissue used to transport substances around the body
functions of blood are (transport) Transport oxygen & nutrients around the body Transporting CO2 & other waste products away from cells Transporting chemical messages - hormones - to the cells Maintaining the pH of body fluids
functions of blood are Distributing heat & maintaining body temperature Maintaining water content & ion concentration of body fluids Protecting against disease causing microorganisms Clotting when vessels are damaged thus preventing blood loss
Blood is composed of Plasma Formed elements
Formed elements the non-liquid part of blood (cell/cell-like structure: red&white blood cells, platelets) 45% of blood volume
Plasma the liquid part (mixture of water& dissolved substances .i.e. sugar) of blood function : transport components of blood around body - hormones, cel, waste 55% of blood volume
oxyhaemoglobin (97%) transported by combining with haemoglobin in a loose bond. The loose bond allows easy release of oxygen Oxygen attaches to the haemoglobin when in high oxygen concentration (alveoli) and detaches when in low concentration arrea (capilaries)
Deoxygenated blood oxygen poor/ high proportion of haemoglobin in blood
Oxygenated blood oxygen rich/ high proportion of oxyhaemoglobin in blood
Haemoglobin specialised Carry haemooglobin - can combine with oxygen No nucleus - more room for oxygen Biconcave disc shape - increases surface area for oxygen exchange but thick edges to increase volume for room food haemoglobin
Transport of Carbon dioxide 7-8% dissolved in plasma 22% carbaminohemoglobin 70% bicarbonate ions in plasma
bicarbonate ions formula (CO2 + H2O) <-> (H2CO3) <-> (H+ + HCO3) ~neutralise it

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
