Answer:
The function of the circulatory system necessary for the respiratory system to complete the exchanges of gases in the body is red blood cells carrying oxygen away from the lungs (option D)
Explanation:
The respiratory and circulatory systems are related because the supply of oxygen (O₂) to the entire body depends on them, in addition to allowing the expulsion of carbon dioxide (CO₂).
The function of the circulatory system that allows gas exchange in the body and contributes to respiratory function are the red blood cells, which carrying O₂ away from the lungs.
<u>Red blood cells or erythrocytes</u> contain a molecule, hemoglobin, which is responsible for transporting O₂ to the body and removing CO₂ from the tissues to be carried to the lungs for expulsion.
The other options are not correct because:
<em> A and B. White blood cells are not in charge of transporting respiratory gases.</em>
<em> A and C. The exchange of gases does not occur directly to the atmosphere.</em>
Answer:
D Phenylketonuria
Explanation:
Infant jaundice is caused by buildup of a compound bilirubin in infant's blood. It leads to yellowing of skin and eyes. There are several risk factors which should be kept in mind. People with east Asian or Mediterranean descent are at more risk of jaundice. Prolonged bruising during labor can lead to breakdown of more red blood cells hence production of more bilirubin again increasing jaundice risk. If mother's blood type is different from the child, the child might receive antibodies from the mother via placenta, hence breakdown of RBCs . Poor breastfeeding can also lead to improper development of baby making it more susceptible to jaundice.
Phenylketonuria is a metabolism error and leads to reduced metabolism of Phenylalanaine. It has got nothing to do with jaundice.
