Questions Related to components of blood

The blood plasma contains a dissolved substance called ________

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Serum

  2. fibrinogen

  3. hemoglobin

  4. pulmonary

Show answer
Correct Option: C
Explanation:
Blood plasma in human beings consists of a dissolved substance called as Haemoglobin which consists of a haem complex with globin protein. The main function of haemoglobin is oxygen transport within the body. It also acts as a buffer.
So, the correct answer is, 'Hemoglobin'.

Plasma protein involves in defense mechanism is 

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Fibrinogen

  2. Globulins

  3. Albumin

  4. None of the above

Show answer
Correct Option: B
Explanation:

Albumin, fibrinogen and globulin are major plasma proteins in the body.  Globulins are involved in defense mechanisms of the body. These transport ions, hormones, and lipids helping in immune function. Fibrinogens are involved in the clotting or coagulation of blood. Albumins are involved in maintaining the osmotic balance.

Thus, the correct answer is 'Globulins.'

Which of the following is found in blood and not in nephric filtration?

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Urea

  2. Glucose and Globulin

  3. Amino acids

  4. None of the above

Show answer
Correct Option: B
Explanation:

A) Urea is excreted through urine.
B) Glucose is usually only found in the urine when blood glucose levels are raised due to diabetes. This disorder is called glycosuria.

C) Some amino acids like glutamic acid, serine, glycine, threonine, alanine, glutamine, lysine, and tyrosine are found in blood excreted in urine.
D) No significant amount of globulins are found in the urine. Globulins and other proteins are filtered out to form urine. Presence of excess protein bodies in the urine is called proteinuria and indicates kidney damage.
So the correct answer is 'Glucose and Globulin'. 


Plasma without clotting factors is known as

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Serum

  2. Fibrinogen 

  3. Albumin

  4. Both A and B

Show answer
Correct Option: A
Explanation:

The liquid part of the blood is called as plasma. Plasma without clotting factors is known as serum. Albumin, globulin and fibrinogen are major proteins present in the plasma.

Thus, the correct answer is 'Serum.'

The major function of alpha and beta globulins in the plasma is

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. They develop colloidal osmotic pressure

  2. Help in immune response

  3. Act as antigens

  4. Act as carrier proteins

Show answer
Correct Option: D
Explanation:

Alpha and beta globulins function as enzymes and proteins that transport compounds in the body. Gamma globulins act as the antibody defence against antigen invasion. Beta globulins are also manufactured mostly in the liver. 

So the correct option is 'Act as carrier proteins'.

Which is the principal cation in the plasma of the blood?

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Calcium

  2. Sodium

  3. Potassium

  4. Magnesium

Show answer
Correct Option: B
Explanation:

Sodium is the most abundant electrolyte and main cation in the blood plasma which plays a major role in maintaining water balance in the blood and in the tissues. 

So, the correct answer is 'sodium'.

What will happen, if there is an increase in plasma albumin?

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Increased blood pressure

  2. Increased rate of heart

  3. Greater accumulation of tissue fluid

  4. Decrease filtration in the glomerulus

Show answer
Correct Option: A
Explanation:
  • Serum or plasma albumin is the protein found in plasma. 
  • It is most abundant protein in the plasma and constitutes about half the proteins in the plasma.  
  • Albumin transports hormones, fatty acids, and other compounds, buffers pH and maintains oncotic pressure. 
  • Oncotic pressure is a form of osmotic pressure exerted by protein in a blood vessel's plasma. 
  • Therefore, the increase in plasma albumin levels leads to the increased blood pressure and in severe conditions may lead to heart attack. 
  • So, the correct answer is 'increased blood pressure'.

Which of the following is incorrect about ultrafiltration?

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Podocytes are arranged in intricate manner so as to leave minute space called filtration slits and slit pore, filtration occur finely through these pores

  2. Filtration is so fine that almost all constituent of blood except protein pass onto the lumen of Bowman's capsule

  3. Filtrated fluid is isotonic to blood plasma

  4. JGA control filtration rate of Ultrafiltration

Show answer
Correct Option: C
Explanation:

  •  Podocytes are arranged in an intricate manner around in the glomerulus so as to leave minute spaces called filtration slits and slit pores, filtration occurs finely through these pores.
  • Filtration is so fine that almost all constituent of blood except protein pass onto the lumen of Bowman's capsule.
  • The fluid formed after the filtration of blood is more concentrated as compared to blood.
  • JGA controls the rate of Ultrafiltration.
So, the correct answer is 'Filtrated fluid is isotonic to blood plasma'.

The largest amount of $CO _2$ is transported by the blood as?

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. $CO _2$ in the plasma

  2. $H _2CO _3$ in the plasma

  3. Bicarbonate ions in plasma

  4. Bicarbonate ions in the erythrocytes

Show answer
Correct Option: C
Explanation:
Carbon dioxide produced in the body is transported either in the plasma, in the form of bicarbonate ions or in the form of carbaminohemoglobin. The maximum amount of carbon dioxide is transported in the form of bicarbonate ions formed in the erythrocytes.

So, the correct answer is 'Bicarbonate ions in plasma'.
