What is the primary function of erythrocytes in the blood?
To carry oxygen in the blood
Which type of blood cell is responsible for immune function and fighting infection?
Leukocytes
What is the term for the process of blood clotting?
Thrombosis
What is the primary function of thrombocytes in the blood?
To form blood clots
Which of the following blood components is NOT involved in immune function?
Erythrocytes
Match the correct description to the blood cell
Erythrocytes = red blood cells (RBC), Carry oxygen in our blood Leukocytes = white blood cells (WBC), Immune function/fight infection/wound healing Thrombocytes = platelets, Clotting (thrombosis = clotting) Erythrocytes = Biconcave
Erythrocytes are the following?
Biconcave , “bi” = two, concave = curves inwards, Increased surface area for gas exchange
Erythrocytes
Produced in the bone marrow – in response to erythropoietin – a hormone produced by the kidneys. Spleen and liver are major sites for the breakdown of RBC (haemolysis) Lifespan = 110 days on average
Erythrocytes Function is to carry O2 to the tissues utilises haemoglobin for this
True
What is the primary function of haemoglobin in erythrocytes?
To carry oxygen molecules
Why is iron essential for erythrocytes to function efficiently?
Because iron is attached to the protein molecules in haemoglobin
What is the result of haemoglobin binding to oxygen molecules?
Oxyhaemoglobin forms
What is the reason people feel tired when they are iron deficient?
Because iron is necessary for haemoglobin to function efficiently
What is the colour of deoxyhaemoglobin?
Purplish-blue
What is the effect of iron deficiency on the ability of erythrocytes to carry oxygen?
Erythrocytes can carry less oxygen
Why are erythrocytes more efficient at carrying oxygen than if oxygen were dissolved in plasma?
Because erythrocytes have a higher concentration of haemoglobin
What is the colour of oxygenated haemoglobin?
Red
What is the function of the iron atom in haemoglobin?
To carry oxygen molecules
How many oxygen molecules can each molecule of haemoglobin bind?
Four
What is the primary function of the protein molecules in haemoglobin?
To carry oxygen molecules
Why are erythrocytes packed full of haemoglobin molecules?
To make RBC more efficient
What is the term for oxygenated haemoglobin?
Oxyhaemoglobin
How many iron atoms are attached to each molecule of haemoglobin?
1
What is the colour of deoxygenated haemoglobin?
Purplish-blue
Each molecule of haemoglobin can bind three molecules of O2
False
The main function of haemoglobin is to carry carbon dioxide from the tissues to the lungs
False
Haemoglobin is a protein contained in erythrocytes that carries oxygen
True
Erythrocytes are less efficient at carrying oxygen than if oxygen were dissolved in plasma
False
Deoxyhaemoglobin is oxygenated haemoglobin
False
Each molecule of haemoglobin is made up of ______ protein molecules that have an iron atom attached to it.
4
Erythrocytes are packed full of ______ molecules.
haemoglobin
[Blank]haemoglobin is oxygenated haemoglobin - red.
Oxy
Each Fe atom can carry one ______ molecule.
oxygen
Deoxyhaemoglobin is ______ haemoglobin – purplish-blue.
deoxygenated
What is the primary route of carbon dioxide transport from the cells to the lungs?
Dissolved in the serum
How does the body remove CO2 from the tissues?
Through the bloodstream and exhalation
What is the difference in CO2 transport between the RBC and serum?
Most CO2 is dissolved in the serum
Why is CO2 transport important in the body?
To remove waste products from the tissues
What is the final destination of CO2 transport in the body?
Lungs
What is the primary route of carbon dioxide transport from the cells to the lungs?
Dissolved and transported in the serum
Where is CO2 mostly dissolved and transported?
In the serum
What is the waste product of tissue metabolism that needs to be removed from the body?
Carbon dioxide
Why do we need to remove CO2 from the body?
Because it is a waste product of tissue metabolism
What is the process by which CO2 is removed from the body?
Exhalation
What is the primary role of serum in the transportation of CO2?
To dissolve and transport CO2 from the cells to the lungs
How does CO2 diffuse from the tissues into the bloodstream?
Through the diffusion of CO2 from the tissues into the plasma in the capillaries
What is the fate of CO2 produced by the cells as a waste product of tissue metabolism?
It is released into the bloodstream and transported to the lungs for exhalation
What is the primary difference between the transportation of O2 and CO2 in the bloodstream?
O2 is transported by RBC, while CO2 is transported by serum
Why is the transportation of CO2 from the cells to the lungs necessary?
To remove CO2, a waste product of tissue metabolism, from the body
