deoxygenated

Examples of deoxygenated in the following topics:

• 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.

• 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.

• The Respiratory System and Direct Diffusion

  • A respiratory cycle consists of an inhalation and an exhalation: with every normal inhalation, oxygenated air fills the lungs, while with every exhalation, deoxygenated air rushes back out.

• Transport of Oxygen in the Blood

  • As a result, oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red.
