Questions Related to blood and its components
The blood plasma contains a dissolved substance called ________
-
Serum
-
fibrinogen
-
hemoglobin
-
pulmonary
Plasma protein involves in defense mechanism is
-
Fibrinogen
-
Globulins
-
Albumin
-
None of the above
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.
Which of the following is found in blood and not in nephric filtration?
-
Urea
-
Glucose and Globulin
-
Amino acids
-
None of the above
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.
Plasma without clotting factors is known as
-
Serum
-
Fibrinogen
-
Albumin
-
Both A and B
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.
The major function of alpha and beta globulins in the plasma is
-
They develop colloidal osmotic pressure
-
Help in immune response
-
Act as antigens
-
Act as carrier proteins
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.
Which is the principal cation in the plasma of the blood?
-
Calcium
-
Sodium
-
Potassium
-
Magnesium
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.
What will happen, if there is an increase in plasma albumin?
-
Increased blood pressure
-
Increased rate of heart
-
Greater accumulation of tissue fluid
-
Decrease filtration in the glomerulus
- 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?
-
Podocytes are arranged in intricate manner so as to leave minute space called filtration slits and slit pore, filtration occur finely through these pores
-
Filtration is so fine that almost all constituent of blood except protein pass onto the lumen of Bowman's capsule
-
Filtrated fluid is isotonic to blood plasma
-
JGA control filtration rate of Ultrafiltration
- 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.
The largest amount of $CO _2$ is transported by the blood as?
-
$CO _2$ in the plasma
-
$H _2CO _3$ in the plasma
-
Bicarbonate ions in plasma
-
Bicarbonate ions in the erythrocytes
From the following terms, choose one term which includes the other four.
-
Plasma
-
Platelets
-
Blood
-
RBC
-
WBC
