The chylomicrons circulate throughout the body, giving the blood plasma a milky or creamy appearance after a fatty meal. [ citation needed ] Lipoprotein lipase on the endothelial surfaces of the capillaries, especially in adipose tissue , but to a lesser extent also in other tissues, partially digests the chylomicrons into free fatty acids ...
The sodium-calcium exchanger (often denoted Na + /Ca 2+ exchanger, exchange protein, or NCX) is an antiporter membrane protein that removes calcium from cells. It uses the energy that is stored in the electrochemical gradient of sodium (Na +) by allowing Na + to flow down its gradient across the plasma membrane in exchange for the countertransport of calcium ions (Ca 2+).
Hypocalcemia (low blood calcium) and hypercalcemia (high blood calcium) are both serious medical disorders. Osteoporosis, osteomalacia and rickets are bone disorders linked to calcium metabolism disorders and effects of vitamin D. Renal osteodystrophy is a consequence of chronic kidney failure related to the calcium metabolism.
Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [1] [2] It also contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages.
Structural formula of the adipate dianion. The anionic (HO 2 C(CH 2) 4 CO 2 −) and dianionic (− O 2 C(CH 2) 4 CO 2 −) forms of adipic acid are referred to as adipates. An adipate compound is a carboxylate salt or ester of the acid. Some adipate salts are used as acidity regulators, including: Sodium adipate (E number E356) Potassium ...
In 1553, Michael Servetus said that blood flows from the heart to the lungs, and that it there mixes with air to form the arterial blood which flows back to the heart. Between 1570 and 1590, Cesalpino suggested, in a controversy with Galenists , that the movement of blood was more like a circulation than an oscillation; but this view lacks clarity.

One of the main roles of extracellular fluid is to facilitate the exchange of molecular oxygen from blood to tissue cells and for carbon dioxide, CO 2, produced in cell mitochondria, back to the blood. Since carbon dioxide is about 20 times more soluble in water than oxygen, it can relatively easily diffuse in the aqueous fluid between cells ...
