Chapter 7 Circulatory System

Question 1

What are the three types of white blood cells?

Answer 1

Granulacytes: have granules and first at site of injury
Monocytes: have large nucleus
Lymphocytes: found in lymph and smaller

Question 2

What are the three ways oxygen can travel through the blood?

Answer 2

• Dissolved in the plasma(3%)

- Bound to the haemoglobin(97%)

Question 3

Explain the travel of oxygen through the binding of haemoglobin?

Answer 3

• places of high oxygen concentration
• O2 binds to haemoglobin
• Oxyhaemoglobin is formed
• areas of low 02 concentration
• CO2+ haemoglobin split apart and 02 diffuses into tissues

Question 4

What are the characteristics of red blood cells?

Answer 4

• has a orythrocyte which transports oxygen
• have no nucleus
• bacon cave shaped to increase surface area for diffusion
• produced in the bone marrow

Question 5

What are three ways Co2 is carried in blood

Answer 5

• dissolved in the plasma(8%)
• bound to haemoglobin as carbonimohaemoglobin(22%)
• as hydrogen and bicarbonate ions(70%)

Question 6

What is the main way Co2 is transported in blood?

Answer 6

• most Co2 reacts with water to form carbonic acid
• the carbonic acid then disassociates into hydrogen and bicarbonate ions
• the process is reversed in the capillaries around the alveoli
• Ions recombine and breaks down through enzymes
• Co2 diffuses into alveoli
