The progenitor of the platelets is called a megakaryocyte.
Explanation:
Platelets are blood structures, which participate in the process of blood clotting. They are also known as thrombocytes.
The process of platelet formation is called thrombopoiesis, and it consists of
- <em>Formation of megakaryoblasts from the hemocyte, a hematopoietic precursor cell. </em>
- <em>Megakaryoblasts produce </em><em>megakaryocytes</em><em>.
</em>
- <em>Megakaryocytes are precursors to platelet</em><em>s.
</em>
Each megakaryocyte must fragment to form the thrombocytes or platelets.
Answer: Liver
Explanation:
The liver is the largest gland in the body, weighing 1200 to 1500g, with a smooth surface and reddish-brown color. It is located in the upper right quadrant of the abdomen, it is pyramidal in shape, and is in a slightly oblique position, Having two faces: one upper anterior, directly in contact with the diaphragm and a lower poster, directly in contact with the underlying abdominal viscera. the falciform ligament topographically divides the diaphragmatic liver face into right and left lobes.
Fixing the upper poster, in each hepatic lobe, we find the coronary ligaments, which unite at their extreme laterals giving rise to the triangular ligaments and anteriorly on the diaphragmatic face, originating the falciform ligament.
