Which of the following components are present in the plasma?
-
Water
-
Salt
-
Proteins
-
All of the above
One half of blood is composed of red blood cells, white blood cells and platelets which are considered as solid part of blood and another half is composed of water, salts and proteins which is the fluid part of blood. The fluid part of blood is known as plasma. Hence the components present in the plasma are water, salts and proteins.
The matrix of the plasma contains
-
Water and Salts
-
Blood cells
-
Only platelets
-
Only RBCs and WBCs
Plasma is the extracellular matrix which holds the blood cells. It makes 55 percent of the total blood volume. It consists of 95% of water and 8% of proteins. The protein like serum albumins, globulins, fibrinogen etc. In addition, it also contains glucose, electrolytes and clotting factors. Thus, the correct answer is option A.
Percentage of protein is more in
-
Lymph
-
Blood
-
Plasma
-
W.B.C
Blood proteins connected with antibodies are
-
Albumins
-
$\beta$-globulins
-
Gamma globulins
-
$\alpha$-globulins
Most of the blood proteins are
-
Acidic
-
Basic
-
Neutral
-
All the above in equal proportions
Plasma is composed of 90-92% water and 6-8 % plasma proteins. Fibrinogen, globulins and albumins are the major proteins. The pH of blood is 7.35 to 7.45 slightly alkaline. Most of the blood proteins are acidic in order to neutralize the pH of blood.
About $97\%$ of oxygen is transported by RBC. The remaining $3\%$ is?
-
Retained in lungs
-
Dissolved in plasma and transported
-
Attached to cell membrane
-
Inside mitochondria
-
In peroxisomes
The amount of water present in blood plasma is
-
60%
-
70%
-
80%
-
90%
Blood does not contain
-
Calcium.
-
Prothrombin.
-
Fibrinogen.
-
Elastin.
Elastin is a highly elastic protein found in certain connective tissues throughout the body. It is mostly found in the extracellular matrix of the skin and internal organs of the body. Calcium, prothrombin, and fibrinogen are the blood clotting factors present in the blood. Blood is a fluid connective tissue it does not require elasticity hence elastin is absent in blood.
The major proteins of blood plasma are
-
Albumin, globulin and fibrinogen.
-
Collagen, elastin and fibrinogen.
-
Albumin, glutelin and p-protein.
-
Actin, myosin and tubulin.
