deoxygenated

Examples of deoxygenated in the following topics:

• Blood Flow in the Heart

  • The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs.
  • The blood that is returned to the right atrium is deoxygenated and is passed into the right ventricle to be pumped through the pulmonary artery to the lungs for re-oxygenation and removal of carbon dioxide.
  • The coronary arteries derive from the aorta and run along the surface of the heart and within the muscle to deliver oxygen-rich blood to the myocardium, while the coronary veins remove deoxygenated blood from the heart muscle returning it through the coronary sinus into the right atrium.
  • Deoxygenated blood is received from the systemic circulation into the right atrium, it is pumped into the right ventricle and then through the pulmonary artery into the lungs.

• Blood Flow in the Lungs

  • Pulmonary circulation in the lungs is responsible for removing carbon dioxide from and replacing oxygen in deoxygenated blood.
  • The pulmonary arteries carry deoxygenated blood to the lungs, where they release carbon dioxide and pick up oxygen during respiration.

• Veins of the Thorax

  • The veins of the thorax drain deoxygenated blood from the thorax region for return to the heart.
  • Two venae cavae return deoxygenated blood from the systemic circulation to the right atrium of the heart.

• Veins of the Abdomen and Pelvis

  • The major veins of the abdomen and pelvis return deoxygenated blood from the abdomen and pelvis to the heart.
  • A number of veins remove deoxygenated blood from the abdomen and pelvis.
  • The superior epigastric vein refers to a blood vessel that carries deoxygenated blood and drains into the internal thoracic vein.

• Great Vessels of the Heart

  • They are the veins that return deoxygenated blood from the body into the heart, emptying into the right atrium.
  • The superior vena cava is a large, short vein that carries deoxygenated blood from the upper half of the body to the right atrium.
  • The inferior vena cava is the largest vein in the body and carries deoxygenated blood from the lower half of the body into the heart.
  • These are the only arteries that carry deoxygenated blood, and are considered arteries because they carry blood away from the heart.
  • It is a short, wide, vessel that then branches into the left and right pulmonary arteries to which deliver deoxygenated blood to the respective lungs.

• Types of Circulatory Systems in Animals

  • This unidirectional flow of blood produces a gradient of oxygenated to deoxygenated blood around the fish's systemic circuit.
  • The ventricle is divided more effectively by a partial septum, which results in less mixing of oxygenated and deoxygenated blood.
  • The oxygenated blood is separated from the deoxygenated blood, which improves the efficiency of double circulation and is probably required for the warm-blooded lifestyle of mammals and birds.
  • The heart is three chambered, but the ventricles are partially separated so some mixing of oxygenated and deoxygenated blood occurs, except in crocodilians and birds.
  • (d) Mammals and birds have the most efficient heart with four chambers that completely separate the oxygenated and deoxygenated blood; it pumps only oxygenated blood through the body and deoxygenated blood to the lungs.

• Substitution Reactions

  • The first two equations illustrate a useful procedure for reducing alcohols to alkanes, known as "Barton-McCombie deoxygenation".
  • Deoxygenation of 1º-alcohols is often effected by LiAlH4 reduction of tosylate derivatives, a technique that is less satisfactory for 2º-alcohols.

• Structures of the Heart

  • The right atrium receives deoxygenated blood from the superior vena cava, which drains blood from the veins of the upper organs and arms.
  • In addition, the right atrium receives blood from the coronary sinus, which drains deoxygenated blood from the heart itself.
  • This deoxygenated blood then passes to the right ventricle through the right atrioventricular valve (tricuspid valve), a flap of connective tissue that opens in only one direction to prevent the backflow of blood.
  • They diverge into capillaries where the heart muscle is supplied with oxygen before converging again into the coronary veins to take the deoxygenated blood back to the right atrium, where the blood will be re-oxygenated through the pulmonary circuit.

• Blood Flow Through the Body

  • The heart pumps oxygenated and deoxygenated blood throughout the body in a complex system of arteries, veins, and capillaries.
  • Oxygenated blood is pumped away from the heart to the rest of the body, while deoxygenated blood is pumped to the lungs where it is reoxygenated before returning to the heart.
  • Red indicates oxygenated blood, while blue indicates deoxygenated blood.

• Venules

  • A venule is a small blood vessel in the microcirculation that allows deoxygenated blood to return from the capillary beds to the larger blood vessels called veins.
