Answer:
Bíceps- tríceps
Explanation:
Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae y el bíceps (antagonista) se relaja.
Answer:
ABO blood grouping system is based on presence or absence of three types of antigen on red blood cells. A and B blood group have A and B antigens respectively. AB blood group has both A and B antigens. O blood group does not have any antigen.
A body with particular blood type will consider other blood group foreign ( because it has different antigen ) and produce antibodies against it. A person with blood type A can not be given B type blood because the antibodies in his body will destroy RBCs with B antigen which may even prove fatal.
AB blood type person can receive blood from both A and B blood groups because he has antigens for both of them so it will produce antibodies for neither of them. He can also receive O type blood because O blood does not have any antigen so it can be given to any person without incompatibility reaction.
However, AB individual can only donate blood to AB individual because his blood cells have both A and B antigens. So, he can only donate blood to an individual who does not produce antibodies for both A and B blood groups and that would only be another AB blood type individual.
Answer:
<h2>1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low),</h2>
Explanation:
HCT is calculated as:
HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100
1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT ranges from 38 to 46% (some sources claim 34.9-44.5%).
*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.
Total blood volume = Packed cell volume + plasma volume.
