plasmas

It is another type of fluid connective tissue. It is characterized by the absence of RBC. Hence, it has a plasma containing only WBC. Some of the plasma proteins found in blood, are absent in the lymph. Lymph flows only inside definite vessels called lymph vessels or lacte..

Lymph is the interstitial fluid that flows into the lymphatic system. It is formed from blood by the passage of substances through the wall of the blood capillaries into the inter cellular tissue spaces. It is formed by the process of diffusion and filtration from the blood. It consists of two part..

The fourth state called plasma refers to the super heated gaseous state. This is a mixture of electrons and positively charged ions with unusual properties. It is found at extremely high temperatures such as interiors of the sun or stars. Astronomers reveal that 99% of all matter in the u..

Every cell, whether it is prokaryotic or eukaryotic, is enclosed in a thin covering called cell membrane . It is also called as plasma membrane or plasma lemma . The cell membrane can only be seen through the electron microscope since its thickness is well below the resolving po..

The lumen of the glomerular capillaries is smaller than the lumen of the afferent arteriole. Similarly the lumen of the outgoing efferent arteriole is twice as small as the afferent arteriole. Consequently, blood is forced to flow through the glomerular capillaries under pressure. This high hydros..

The formed elements are found freely suspended in the liquid plasma. There are three types of formed elements: Red blood corpuscles (RBCs) White blood corpuscles (WBCs) Platele..

These are long, slender thread-like structures, which help in locomotion. A bacterial cell may have one to many flagella. The flagella are entirely composed of a protein called flagellin. The basal body of each flagellum is directly attached to the plasma membrane. It is not covered by a..

If the kidneys are so impaired by disease or injury that they are unable to excrete nitrogenous wastes and regulate pH and electrolyte concentration of the plasma, the blood must be filtered by an artificial device. Such filtering of the blood is called Haemodialysi..

1) The blood flows at a very low velocity and at low pressure due to the absence of smooth muscles. 2) There is direct exchange of materials between the cells and the blood because of the direct contact between them. 3) The respiratory pigment, when present, is dissolved in the plasma of ..

Question: What is the function of the cell wall? Answer: The cell wall lies outside the plasma membrane and is responsible for providing structural strengths to the plants..
