Answer:
From fertilization and to the end of the second week.
Explanation:
The development of the fetus is divided into three periods, established by most embryologists: pre-embyonic period, which goes from fertilization to the second week of development, embryonic period, which goes from the third week to the eighth week, and the fetal period, which goes from from the third month until the end of pregnancy.
The pre-embyonic stage begins at fertilization and remains until gastrulation. By the end of the second week the embryo already has the neural tube formed, although it is still open at both ends.
Some methods of progressive resistance exercise used to improve muscle fitness would be to increase the weight you lift. Do the same amount of reps and sets each week along with that but only increase your weight percentage by 2 or 10 of your RM load at a time. Don’t go overboard.
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>
