The superior vena cava is located in the upper chest region and is formed by the joining of the brachiocephalic veins. These veins drain blood from the upper body regions including the head, neck, and chest. It is bordered by heart structures such as the aorta and pulmonary artery.
The superior vena cava (and inferior vena cava) are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium.
The term pioneer is used to describe the species that first colonize new habituate created by disturbance
Answer:
cause cells to shrink due to an increase in the osmolarity of extracellular fluid.
Explanation:
Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.
A hyperosmotic solution can be defined as a solution having an increased level of osmotic pressure. Thus, when there's a greater amount of solute with respect to another solution in a membrane with close similarities, it is known as hyperosmotic solution.
Basically, hyperosmotic solution gives rise to higher difference between solutes and similar solutions.
Hence, when a normovolemic person consumes a large quantity of a hyperosmotic solution, it will cause cells to shrink due to an increase in the osmolarity of extracellular fluid i.e the total number of solute particles with respect to the concentration of a solution (Osm/L).
The main reason is because they are heavy, and because they don't have to chase their food. They're not predators and their shells give them protection like running away gives protection to other herbivores.
