Circulatory System Functions

1
Circulatory System Functions

• Respiratory O2 and CO2 exchange
• Excretory removes waste from body cells
• Protection clotting, transports white blood
  cells to infections
• Nutrition carries energy and food throughout
  the body
• Regulatory helps to maintain pH and temperature
• Hormonal transfers hormones to organs

Structure of Blood

• Blood is composed of
• 40 cells and 60 plasma
• The cells that in the blood are
• Erythrocytes (red blood cells)
• Leukocytes (white blood cells)
• Platelets

6
Erythrocyte (red blood cell)

• The most abundant blood cell
• Function transport O2 throughout the body

Mammals no cell nucleus
Birds Reptiles cell nucleus
7
Neutrophil

• Function- to stop or slow down foreign organisms
• They work by
• Phagocytosis to eat bacteria and dead cells
• Bacteriocidal to kill bacteria

8
Basophil

• Functions
• Phagocytosis
• Mediate allergic reactions
• Produce heparin and histamine

9
Eosinophil

• Functions
• Moderate the inflammatory response
• phagocytosis

10
Lymphocyte Monocyte

• Lymphocyte plays a vital role in immunity
• T-cells (memory cells) cells are sensitized to
  an antigen, remember that antigen and fight it
  off next time
• B-cells divide to form many cells to fight an
  antigen

• Monocyte largest blood cell
• Function is phagocytosis

11
Thrombocyte

• Function
• Hemostasis (clotting) stop bleeding by adhering
  to damaged vessels and clumping together, release
  proteins that help form a clot
