The main component of the extracellular fluid (ECF) is the interstitial fluid, or tissue fluid, which surrounds the cells in the body. The other major component of the ECF is the intravascular fluid of the circulatory system called blood plasma. The remaining small percentage of ECF includes the transcellular fluid.
The amount of interstitial fluid varies from about 50% of the tissue weight in skin to about 10% in skeletal muscle. [2] Interstitial fluid pressure is variable, ranging from -1 to -4 mmHg in tissues like the skin, intestine and lungs to 21 to 24 mmHg in the liver, kidney and myocardium. Generally, increasing interstitial volume is associated ...
To increase muscle size (called hypertrophy), your body needs to make more muscle protein than it breaks down over time. Eating enough protein is one way to do this. With the right balance of ...
The transcellular fluid is the portion of total body fluid that is formed by the secretory activity of epithelial cells and is contained within specialized epithelial-lined compartments. Fluid does not normally collect in larger amounts in these spaces, [6] [7] and any significant fluid collection in these spaces is physiologically ...
Sarcoplasm is the cytoplasm of a muscle cell.It is comparable to the cytoplasm of other cells, but it contains unusually large amounts of glycogen (a polymer of glucose), myoglobin, a red-colored protein necessary for binding oxygen molecules that diffuse into muscle fibers, and mitochondria.
Protein is vital to our physical and cognitive functioning, supporting organs, hair and nail strength, muscles, and focus. High-protein diets might also assist with weight loss and maintenance.
For example, the muscle tone of the smooth muscle tissue of the tunica media can be adjusted by the renin–angiotensin system. In patients whose endogenous homeostatic regulation is not working well, dozens of pharmaceutical drugs that are also vasoactive can be added. The response of vessels to such vasoactive substances is called ...
Collagen (/ ˈ k ɒ l ə dʒ ə n /) is the main structural protein in the extracellular matrix of the connective tissues of many animals. It is the most abundant protein in mammals, [1] making up 25% to 35% of protein content. Amino acids are bound together to form a triple helix of elongated fibril [2] known as a collagen helix.
