A)Loss of elasticity of the muscular layer
B)Condition of high blood pressure
C)Condition of low blood pressure
D)Condition of anoxia

Answer 1

Hint: The veins are present on the legs, ankles, and feet because there are body parts that are far from the heart. The veins are valves that help keep the blood flowing in the right direction. Valves are like doors that close when the blood has passed through it. So that blood keeps flowing and makes sure that it does not flow backward.

Complete answer:
-When you are standing up or sitting down the gravity pulls blood down into your legs, and in this condition, veins have to work extra to get that blood back to the heart. Some veins are not able to wear it out.
-The veins that are present on the skin, get swells and these are known as varicose veins.
-The varicose veins are caused due to the loss of elasticity in the walls of the veins. Due to this the veins stretch out and slow down the movement of blood back to the heart.
-Therefore this leads to an increase in the blood pressure and causes the veins to swell present below the skin.
-It looks twisted and purple or blue in color and looks like they are sitting on top of the skin which means they are raised.
-They are painful especially when a person sits or stands still for a long time. A person with varicose veins has achy legs and even feels heavy.

Additional Information: The signs of varicose veins include-
During non-painful conditions
1)Veins become dark purple or blue in colors.
2)Veins appear as twisted and bulging.
During painful conditions
1)Ache in the legs or heavy feeling in the legs.
2)Muscles cramping and swelling in the lower legs.
3)Pain gets worse after sitting or standing for a long time.
4)Itching around veins.
5) Around a varicose vein discoloration of the skin occurs.
So, the correct answer is, "Loss of elasticity of the muscular layer".

Note: -The twisted and last ones are the very close ones and the most commonly affected area is in the legs.
-Standing and walking upright increases the pressure in the veins of the lower body, causing veins to swell.
