3.2 The Circulatory System

Text book pages 68-70


Vocabulary

Vocabulary:

  • Arteries

  • Veins

  • Capillaries

  • Atria

  • Ventricle


Circulatory system

Circulatory system

  • Brings every cell oxygen

  • No cell is more than 2 cells away from a blood vessel


3 2 the circulatory system

WOW!!

  • We have 60 trillion cells (60, 000, 000, 000, 000)


1 000 000

1, 000, 000


100 000 000

Wow wow

WOW WOW

  • We have 96 000 km of blood vessels (the earth is 40, 075.16 km around…. So that is MORE then twice around the earth!!


Circulation

Circulation

  • Blood in vessels carry:

    • O2 and nutrient fluids to the cells

    • CO2 and waste away from cells

  • 3 main types of vessels:

    • Arteries: carry blood away from heart

    • Veins: carry blood to the heart

    • Capillaries: smallest vessel (size of 1 RBC)


Our heart

Our Heart

  • 4 chambers

    • Two atria

      • Receive blood into heart

      • Top or heart

    • Two ventricles

      • Pumps blood away from hearth

      • Bottom of heart

      • Stronger, more muscular


Flow of blood through the heart

Flow of blood through the heart:

  • Veins (deoxygenated blood from body)

  • Right atrium (RA)

  • Right ventricle (RV)

  • Lungs (get exchange CO2gas for O2gas at the alveoli)

  • Left atrium (LA)(oxygenated blood form lungs

  • Left ventricle (LV)

  • Aorta

  • Body

A one way flow

A one-way flow

  • Valves = one way doors

    • Found between RA and RV, and LA and LV

    • Ventricles and arteries

    • In veins


Our heart beat

Our heart beat

  • “LUBB” “DUBB”

  • “LUBB” = ventricles contracting and closing valves between Atria and Ventricles

  • “DUBB” valves closing between the arteries and the ventricles
