What is the difference between what is cell fluid and what is the difference between intracellular f

Cell fluid: The fluid in the vacuole of plant cells is called cell fluid, which is dissolved in inorganic salts, amino acids, sugars, and various pigments, especially anthocyanins. The cell fluid is hypertonic, so the plant cells can always be in a state of swelling and fullness.

The anthocyanins in the cell fluid are related to the color of the plant, and the purple and dark red colors of flowers, fruits, and leaves are determined by the anthocyanins. In addition, vacuoles are also a site for the accumulation of plant metabolic wastes, which are deposited in the vacuoles in a crystalline state.

1. The composition is different.

Cell fluid: inorganic salts, amino acids, sugars and various pigments.

Intracellular fluid: Intracellular fluid consists of small molecules of water and inorganic ions, medium molecules of lipids, amino acids and nucleotides, and macromolecules of proteins, nucleic acids, lipoproteins and polysaccharides. The ionic composition is very different from that of extracellular fluid.

2. The function is different.

Cell sap: a place where plant metabolic wastes are accumulated.

Intracellular fluid: It plays an important role in maintaining the structure and function of cells and maintaining the pH stability of intracellular fluid.

Cytofluid is the fluid in vacuoles in plant cells.

The concept of intracellular fluid generally appears in higher animal cells and mainly refers to the fluid inside the cell. It is relative to the extracellular fluid, which is the internal environment, which includes tissue fluid, plasma, and lymph.

The fluid in the vacuole of the plant is called the cell fluid. The body fluid that exists in the cell, and its chemical composition and content directly affect the metabolism and physiological functions of the cell, is called intracellular fluid. Animal cells are mostly free of cell fluid because they do not have vacuoles.

From the perspective of the internal environment, the cell fluid should belong to the category of intracellular fluid.

Body fluids can be divided into two main parts: intracellular fluid and extracellular fluid. The fluid that exists inside the cell is called intracellular fluid and makes up about 40% of body weightThe one that is present outside the cell is called extracellular fluid.

Extracellular fluids are further divided into two categories:

One is the interstitial fluid (including lymph and cerebrospinal fluid) that exists between tissue cells, accounting for about 16% of body weight

The other category is blood plasma (about 4% of body weight).

Blood, lymph, and tissue fluids between organs and tissues are all body fluids.

Intracellular fluid is the fluid inside the cell.

The space between tissues and cells is called the interstitial space, which is filled with interstitial fluid. Interstitial fluid is the environment in which tissues and cells are directly exposed. Tissues and cells exchange substances through cell membranes and interstitial fluids.

The interstitial fluid and the blood are exchanged through the capillary walls. Therefore, the exchange of substances between tissues, cells, and blood is mediated by interstitial fluid. Interstitial fluid is formed by the filtration of plasma through the walls of capillaries.

Body fluids are the sum total of all the fluid components in the cells of higher animals, excluding plants. Body fluids in turn include intracellular fluid and extracellular fluid. Intracellular fluid mainly includes cytoplasmic matrix, nuclear fluid, and cytofluid of the matrix of organelles; Extracellular fluid:

There are mainly tissue fluid, plasma (non-blood), lymph, and cerebrospinal fluid.

Human body fluids account for about 65% of body weight, most of which are found in cells, called intracellular fluid, which is the basic component of protoplasm; A small part is found outside the cell and is called extracellular fluid. Intracellular fluid accounts for about 2 3 of body fluids.

Extracellular fluid refers to the body fluid that exists outside the cells in the human body, called extracellular fluid (extracellularfluidecf).It mainly includes interstitial fluid (short for interstitial fluid), plasma (the liquid part of blood) and lymph, cerebrospinal fluid, etc. It accounts for one-third of the total body fluids.

The extracellular fluid in the human body constitutes the liquid environment in which the cells in the body live, and this liquid environment is called the internal environment of the human body.

The intracellular fluid consists of small molecules of water and inorganic ions, medium molecules of lipids, amino acids, and nucleotides, and large molecules of proteins, nucleic acids, lipoproteins, and polysaccharides. The ionic composition is very different from that of extracellular fluid. The cations of the intracellular fluid are mainly K, and its content accounts for more than 90% of the total cations in the intracellular fluid, as well as a small amount of sodium ions and magnesium ions, etc., and the anions are mainly HPO4, H2PO4 and protein, and the content of other anions is very small.

These ions play an important role in maintaining the stability and electrical neutrality of the osmotic pressure of the intracellular fluid, among which HPO4, H2PO4 and proteins play an important role in maintaining the pH stability of the intracellular fluid.

Data expansion: Humoral regulation refers to the production of certain chemicals (hormones, histamine, CO2, H+, etc.) by cells, and the regulation of physiological functions such as metabolism, growth, development, and reproduction of the body through the transmission of body fluids (plasma, tissue fluid, lymph, etc.). It is mainly hormonal regulation.

The effects are generally slow, broad and long-lasting.

Some endocrine cells can directly sense the changes of certain physical and chemical factors in the internal environment and directly respond accordingly. For example, when the concentration of calcium ions in the blood decreases, parathyroid cells can directly feel this change, which promotes the increase in the secretion of parathyroid hormone, which in turn leads to the release of calcium in the bone into the blood, so that the concentration of calcium ions in the blood rises, maintaining the homeostasis of the internal environment. There are also endocrine glands themselves that are directly or indirectly regulated by the nervous system, in which case humoral regulation is an efferent link of neuromodulation, an extension of the reflex efferent pathway.

This condition can be referred to as neuro-humoral modulation. For example, the adrenal medulla is innervated by the sympathetic nerves, and when the sympathetic nervous system is excited, the adrenaline and norepinephrine secreted by the adrenal medulla increase, which together participate in the regulation of the body.
