Blood and its composition

Questions and Answers

1.

Blood is made up on
- A.
  
  Nucleus
- B.
  
  Plasma
- C.
  
  Carbohydrates
- D.
  
  Red blood cells
- E.
  
  White blood cells
- F.
  
  Platelets
- G.
  
  Fats
Correct Answer(s)
B. Plasma
D. Red blood cells
E. White blood cells
F. Platelets

Explanation
Blood is composed of various components, including plasma, red blood cells, white blood cells, and platelets. Plasma is the liquid portion of blood that carries nutrients, hormones, and waste products throughout the body. Red blood cells are responsible for carrying oxygen to the body's tissues and removing carbon dioxide. White blood cells are part of the immune system and help fight off infections and diseases. Platelets are involved in blood clotting, preventing excessive bleeding. Therefore, the correct answer includes plasma, red blood cells, white blood cells, and platelets.

2.

Choose those that apply: The functions of blood are to
- A.
  
  Fight against toxins.
- B.
  
  Limit loss of fluids at injury sites.
- C.
  
  Send electrical currents to the cells.
- D.
  
  Stabilize body temperature.
- E.
  
  Transport gases, nutrients and wastes around the body.
Correct Answer(s)
A. Fight against toxins.
B. Limit loss of fluids at injury sites.
D. Stabilize body temperature.
E. Transport gases, nutrients and wastes around the body.

Explanation
Blood performs several important functions in the body. It helps fight against toxins by carrying immune cells and antibodies that can neutralize or eliminate harmful substances. It also helps limit the loss of fluids at injury sites by forming blood clots to stop bleeding. Blood plays a role in stabilizing body temperature by absorbing and releasing heat as needed. Additionally, it transports gases, nutrients, and wastes around the body, ensuring that cells receive oxygen and nutrients and that waste products are removed.

3.

Antigens are known as agglutinogens.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Antigens are substances that can stimulate an immune response in the body. Agglutinogens are a type of antigen that can cause the clumping or agglutination of red blood cells. This process is important in blood typing and transfusions. Therefore, it is correct to say that antigens are known as agglutinogens.

4.

The difference between blood groups is due to the _________ found on the surface of the blood cells.

Correct Answer
antigens

Explanation
Blood groups are determined by the presence or absence of specific molecules called antigens on the surface of blood cells. These antigens can be different for different blood groups, leading to variations in blood types. The immune system recognizes these antigens and produces antibodies against antigens that are not present on its own blood cells. This is why blood transfusions must be carefully matched to ensure compatibility between the donor and recipient blood types.

5.

Agglutination is the same as clotting.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
As agglutination proceeds, millions of red cells are glued together into clumps. When agglutination occurs, the blood mostly remains liquid. But during clotting, the blood starts to gel together and starts to form solid materials such as the platelet plug.

6.

The control of blood loss is also known as hemodialysis.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
It is known as hemostasis.

Rate this question:
7.

The 3 phases to control blood loss are
- A.
  
  Coagulation phase.
- B.
  
  Dilation phase.
- C.
  
  Vascular contraction phase.
- D.
  
  Platelet formation phase.
- E.
  
  Shivering phase.
Correct Answer(s)
A. Coagulation pHase.
C. Vascular contraction pHase.
D. Platelet formation pHase.

Explanation
The correct answer is coagulation phase, vascular contraction phase, and platelet formation phase. These three phases work together to control blood loss. During the coagulation phase, clotting factors in the blood form a clot to stop bleeding. The vascular contraction phase involves the contraction of blood vessels to reduce blood flow to the injured area. Platelet formation phase refers to the production of platelets, which are essential for blood clotting. These three phases are crucial in preventing excessive bleeding and promoting wound healing.
