• The circulatory system, sometimes called the ______________


  cardiovascular system
• circulatory system, sometimes called the cardiovascular system, consists of


  heart, blood vessels, and blood.
• It transports oxygen, hormones and nutrients to all the cells in the body


  The circulatory system,
• The circulatory system, transports _____________________ to all the cells in the body

  oxygen, hormones and nutrients
• It picks up waste products generated by metabolic processes and delivers them to other organs for disposal.

  The circulatory system
• The ___________provides the "_____________" needed to pump blood throughout the body

  HEART

  MUSCLE
• The system circulates blood in two circuits:

  The Pulmonary circuit and Systemic circuit.
• Transports oxygen-poor blood from the right ventricle to the lungs where blood picks up a new oxygen supply


  Pulmonary circulation
• your ________ pumps blood through two major pathways

  heart
• It returns oxygen rich blood and nutrients to the left atrium and is pumped out all over the body


  Systemic circulation
• It also picks up carbon dioxide and other waste products.

  Systemic circulation
• enters the heart from the body (blue, top left) and is pumped out to the lungs (blue, top right)

  Oxygen-poor blood
• enters the heart from the lungs (red, right side) and is pumped out to the body (top)

  Oxygen-rich blood
• ____________ from glands help regulate cell activity

  Hormones
• _____________ from the lungs combines with nutrients to provide energy.

  Oxygen
• ____________from the digestive system provide food for the cells

  Nutrients
• When your blood circulates through your ___________________, it picks up nutrients your body absorbed from your last meal.

  digestive system
• The circulatory system carries __________________________and the immune system's ______________ that fight off infection.

  -hormones from the endocrine system

  -white blood cells
• The circulatory system provides your _________ with a constant supply of _____________ while your brain regulates your ___________ and _____________

  brain

  oxygen-rich blood

  heart rate

  blood pressure.
• Your circulatory system delivers oxygen-rich blood to your _________. Meanwhile, your bones are busy making ____________

  new blood cells.
• - Over 60,000 miles of ____________ transport your blood throughout your body.

  BLOOD VESSELS
• 3 types of BLOOD VESSELS

  arteries, veins, capillaries
• Blood vessels that carry blood away from the heart to other parts of the body.

  Arteries
• They are much thicker than Veins because of the high pressure of blood coming from the heart.

  Arteries
• Blood vessels that carry blood from the body back to the heart.

  Veins
• Tiny tubes that carry blood from the arteries to the body's cells, and then back to the veins.

  Capillaries
• • Body tissues contain a vast network of thin ____________.

  CAPILLARIES
• _____________ are only one cell thick, allowing exchange of gases, nutrients, and wastes.

  • Capillary walls
• ______________ are so fine that red blood cells must ______________ to go through them.

  CAPILLARIES

  line up single-file
• Blood forms about _______ of the body weight of an adult, amounting to about ____________ in volume.

  one-twelfth

  5 liters (11 pints)

  45-50%
• roughly _______% is blood of plasma

  50-55%
• Plasma contains ________ with dissolved substances

  90% water
• Plasma contains 90 per cent water with dissolved substances such as __________, and also waste products such as _________

  glucose (blood sugar), hormones, enzymes

  
  

  - urea and lactic acid.
• Plasma also contains proteins such as ____________, and ____________

  -albumin, fibrinogen

  
  

  globular proteins or globulins.
• protein that is (important in clotting),

  fibrinogen

• Lack a nucleus Contain hemoglobin Disk-shaped


  Red Blood Cells
• RED BLOOD CELLS are produced in red bone marrow of the:

  ribs

  Humerus (upper arm bone)
