Answer:
) a delay of the action potential at the atrioventricular node
Explanation:
The reason for the short delay of 0.9s. is to ensure maximum contractions of the atrial to eject blood into the relaxed ventricles.(ventricular filing).
Thus when the atrial is contracting,the ventricles relax and vice versa.The short duration for the artrial contraction to occur for blood ejection into the relax ventricles guarantee that artial systole can not overlap the ventricle systole.
The artial must contract first for the ventricle fillings,and when this is completed,the atrioventricular valves closes,and blood flow through the aorta to the systemic circulation from the left ventricle and into the pulmonary circulation through the pulmonary vein.
This occurs simultaneously with both the R and L Artrial,and right and left Ventricles.
Well, leukocytes and white blood cells are the same thing, and they have a nucleus so you cant rule those out. Nerve cells also have a nucleus that contains genes.. in that case, the answer is <span>erythrocytes.</span>
Answer:
E. The author of the health record suspects that a clot is blocking a blood vessel in the patient's calf and has prescribed a drug that will prevent the blood from clotting.
Explanation:
- Septicemia is a bacterial infection in the blood. According to the report, the patient will continue to receive IV antibiotics.
- Anemia is a deficiency of hemoglobin or red blood cells. Coagulopathy is the impairment of blood coagulation. This is a bleeding disorder characterized by excess, uncontrolled bleeding.
- Thrombocytopenia is characterized by a deficiency of platelets, leading to decreased coagulation.
- Thromboembolism is the blockage of blood vessels due to the dislodging of a blood clot.
- Hyperbilirubinemia is the excess of bilirubin in the blood due to reduced liver function.
The option E states correctly that the patient has thromboembolism, leading to swelling of the calf. However, the doctor has not yet prescribed a medication. The report states that a medication will be prescribed after a hematology/oncology consultation.
Definietly C because both of the new dna strand will end up together in a new cell and the other one will be discarded from the cell
