Research will be done over the Circulatory System also known as the Cardiovascular System.
Research disease associated with this system
Choose 3 diseases and explain the symptoms of each disease
Explain the treatment for each disease

Explanation:

1). coronary artery disease = damage to major arteries of the heart, treated by blood thinners, change of diet, exercise.

2). high blood pressure = force of blood against artery walls are too high. treatment is diet with less sodium, more exercise & diuretics,(rids body of excess fluids).

3). cardiac arrest (heart attack). unexpected loss of breathing, consciousness, heart function. treatment is antiarrithmic drugs, pacemaker, blood pressure support, change of diet.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
