Very small changes in the solute concentrations in the various fluid compartments cause water to move from one compartment to an
Oksana_A [137]

Answer:

a. Decrease water reabsorption : decrease blood pressure.

b. Decrease peripheral resistance : decrease blood pressure

c. Vasodilation : decrease blood pressure

d. Decrease salt intake : decrease blood pressure

e. Decrease blood volume : decrease blood pressure

f. Vasoconstriction : increase blood pressure

g. Increase peripheral resistance:  increase blood pressure

h. Increase salt intake:  increase blood pressure

i. Increase blood volume : increase blood pressure

j. Increase water reabsorption: increase blood pressure

Explanation:

  • Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow.  This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance.    
  • Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows.  This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others.    
  • Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure.
  • The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs.
  • Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.

Which statement correctly compares the thicknesses of Earth’s layers?
saw5 [17]
The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.

Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.

Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.

Molly's cut is bleeding and she is worried that it will not stop. Using your knowledge of the homeostatic process, what would yo
olga nikolaevna [1]

Answer:

Tell Molly that the bleeding will stop because hemostasis is the way the body stops blood loss when something happens to a vessel. This is the process of the blood clotting. If we didn't have hemostasis bleeding would continue. Unless she has hemophilia, the blood will stop. The first thing that happens is vascular constriction, then formations of platelet plugs, then the blood clots (coagulation) last the fibrous tissue grows (Fibrosis and fibrinolysis)
