The heart is a muscular pump which needs oxygen and sugar for energy. These reach the muscle through the coronary arteries which supply a network of capillaries throughout the myocardium (the muscle of the heart). Carbon dioxide and other products of the heart work, such as pyruvic acid, ...
Olson, a biochemist, is primarily interested in the contractile proteins of heart muscle. These are myosin, actin, and tropomyosin. Myosin, the main constituent ofdoi:10.1016/S0140-6736(61)90471-8The Lancetjournal of the american medical association...
The cardiovascular system (CVS) is made up of the heart, blood vessels, and blood. The fundamental function of CVS is to transport substances to and from all parts of the body. The heart is the major pumping organ, pressurizing blood for circulation thro

- 《Indian Journal of Plant Physiology》 被引量: 21发表: 2008年 Stimulation of muscle protein synthesis by somatotropin in pigs is independent of the somatotropin-induced increase in circulating insulin Chronic treatment of growing pigs with porcine somatotropin (pST) promotes protein synthesis and ...
[1]Likewise, medications like metoclopramide can stimulate and promote gastric emptying by increasing smooth muscle signaling. Perhaps one of the most well-known uses of medical therapy and smooth muscle is the use of nitrates in the treatment of ischemic heart disease.[2]Research showed that ...
