• Veins
  • This impaired filling causes the increased blood flow to back up into the venous system, causing the jugular vein distension (JVD) and is seen clinically in the internal jugular veins becoming more readily visible. (wikipedia.org)
  • immune system
  • CB2 receptors are structurally different (the sequence similarity between the two subtypes of receptors is 44%), found only on cells of the immune system, and seems to function similarly to its CB1 counterpart. (wikipedia.org)
  • It has various roles in the body of humans and other animals, specifically stimulation of extravascular smooth muscle, vasodilation, hypertensive action, immune system activation, and pain management. (wikipedia.org)
  • Tachykinins thus have a number of neuroprotective physiological roles in medical conditions The immune system is a highly integrated system which receives input from many sources, such as sites of injury, nocireceptors and white blood cells. (wikipedia.org)
  • coronary
  • Furthermore, recent research has linked testosterone replacement therapy to an increase in deaths and other cardiovascular occurrences in men whom document a history of coronary artery disease. (wikipedia.org)
  • heart
  • To understand the cardiovascular system, we can follow the path of blood, beginning in the heart. (scai.org)
  • In this section the radiographic appearance of the cardiovascular system is described including changes seen with left- and right-sided congestive heart failure, and the normal size and shape of the heart followed by the radiographic features of individual chamber enlargement. (provet.co.uk)
  • The most common areas affected include: skin (80-90%), respiratory (70%), gastrointestinal (30-45%), heart and vasculature (10-45%), and central nervous system (10-15%) with usually two or more being involved. (wikipedia.org)
  • body
  • The human body has different systems for handling different functions. (scai.org)
  • The system collaborates with white blood cells in lymph nodes to protect the body from being infected by cancer cells, fungi, viruses or bacteria. (wikipedia.org)
  • Follow
  • Like most other neurological processes, the effects of cannabis on the brain follow the standard protocol of signal transduction, the electrochemical system of sending signals through neurons for a biological response. (wikipedia.org)
  • pump
  • Ram ventilation is said to be obligatory in southern bluefin tunas, because the buccal-opercular pump system used by other teleost fish became incapable of producing a stream of ventilation vigorous enough for their needs. (wikipedia.org)
  • maintain
  • To maintain cardiovascular health, the American College of Sports Medicine recommends getting at least 30 minutes of moderate aerobic exercise on five or more days per week, or at least 20 minutes of vigorous exercise on three or more days per week. (livestrong.com)
  • risk
  • Further research is required to determine the full extent to which testosterone replacement therapy in aging men plays a role in the risk and/or advantage of cardiovascular occurrences. (wikipedia.org)
  • function
  • The primary theme remains cardiovascular function, its physiologic and molecular mechanisms, with an aim to understand how these features integrate to achieve overall performance. (wikipedia.org)
  • oxygen
  • On top of a quicker rate of diffusion in the respiratory system of southern bluefin tuna, there is a significant difference in the efficiency of the oxygen uptake. (wikipedia.org)
  • changes
  • This wide range of temperature and depth changes poses a challenge to the respiratory and circulatory systems of the southern bluefin tunas. (wikipedia.org)
