There are three main regions of the kidney.
<span>1.Renal cortex - It is the outer region of the kidney which contains the renal corpuscles and the renal tubules (without the loop of Henle). It produces the erythropoietin.</span>
<span>2.Renal medulla - It is the innermost part of the kidney which contains the renal pyramids.</span>
<span>3.Renal pelvis - It is the region that collects urine from the nephrons, thus it contains the place where ureter leaves the kidney.</span>
Answer:
One of the major goals of environmental science is to understand and to solve environmental problems. In order to accomplish this goal, scientists study two main types of interactions between humans and their environment. One area of focus is on how we use natural resources, such as water and plants.
Explanation:
Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.

Explanation:
Transport vesicles are vesicles that function to carry molecules from one cellular compartment to another. The coat protein complexes I and II (COPI and COPII) are conserved pathways that transport proteins from the endoplasmic reticulum to the Golgi apparatus. Moreover, clathrin is a protein implicated in the formation of coated vesicles. The ADP-ribosylation factor GTPase activating (Arf GAP) proteins play a major role in Arf signaling pathways, which are responsible for uncoating of the COPI coat. On the other hand, COPII vesicles are known to retain their coats until they are recognized by tethering complexes, and whose formation is regulated by the GDP-GTP cycle of the small GTPase Sar1. Finally, the 70-kDa heat shock proteins (HSP70) are chaperones which function as uncoating ATPases to remove clathrin from coated vesicles after endocytosis.
<span>On the left, they drain into the renal vein
which in turn drains into the inferior vena cava. By contrast, all the
lumbar veins and hepatic veins usually drain directly into the inferior vena cava.</span>
