Yes it is

I’m afraid that our manners have been assaulted by the "politically correct" movement if a statement is misunderstood as having a connotation that someone feels as inappropriate you could be fined or even arrested. you would have to let the people around you know where your boundrys lie a lady i once knew had an entire bar of rednecks myself included acitng like gentalmen if only while she was there out of respect for her kind nature

Pressure vessels are constructed to withstand a specific Operating Pressure and have a Maximum Allowable pressure. They may be Horizontal or Vertical Cylindrical, or Spherical, Hemispherical, Small cylinders as for LPG...etc.
They will be fitted with Safety Relief Systems.

Tanks are vessels used at Atmospheric pressure. If pressure is likely to build up in a tank, as when pumping into it, safety relief systems are installed to offset this possibility.
Also, Vacuum breakers are installed for when liquid is being pumped out. A vacuum breaker may incorporate a gas injection (generally an Inert gas like Nitrogen), to maintain a slight positive pressure in the tank depending on the liquid being stored.

Petroleum tankage is very often of the 'Pontoon' or 'Double Deck' type, 'Floating Roof tank' having very little vapour space to minimise vapour loss. The roof 'floats' on the liquid and rises and falls with changes in liquid level.
It also has a special 'Pantograph' seal system against the tank inner wall

inferior vena cava

Perhaps 15-20 years ago they did a study on people who had a "twitch" somewhere on their body... Such things as your eyelid twitching, finger twitching, etc. The doctors studied MRI's of the brain or area involved, ran a multitude of different chemical tests, and exhaustive physical exams in trying to determine exactly what was happening. After all the exhaustive testing & evaluations, they determined that the cause of these "twitches" was just a terminal muscle fiber nerve reacting for no apparent reason. So, to answer your question, I doubt that the twitching finger is a direct result of your back injury. Perhaps some trauma to your finger area occurred at the time of your back injury and resulted in injury to a nerve in that area and is the culprit...

Portal vein bypass surgery diverts blood from the portal vein into another vein. It is performed when pressure in the portal vein is so high that it causes internal bleeding from blood vessels in the esophagus.

Swollen veins

Although treatments for occlusion itself are limited, surgical treatment of the occlusion provides an option.

There is no way the stitch the jugular vein.

Your blood will be on the floor in 4 minutes... I've seen this, I've done this, you don't want this..

No they don't.

Because they dont have water in side them

yes

veins have valves that prevent back flow, and I believe the pressure within circulatory system prevents back flow.

The human body has four major valves in the heart: the mitral valve, tricuspid valve, aortic valve, and pulmonary valve. These valves regulate blood flow through the heart's chambers and into the major arteries. Additionally, the body has numerous other smaller valves, particularly in the veins, but the four heart valves are the primary ones referred to in this context.

Pulsing veins are a sign of stress. I have the same thing. All over my head and face I can feel veins pulsing and can even see them pulsing at the temples and beneath my eyes.

There is more than one injection method:

1. I.V. drip

2. Intravenous Injection

3. Subcutaneous (under the skin)

4. Intra-muscular.

It is to allow the blood to flow in one direction - towards the heart, it prevents back flow.

Perhaps you mean "Señorita, ven". That's Spanish for "Lady, come here". "Señorita" is used for unmarried women, similar to "Miss".

There are three major categories of veins: superficial veins, deep veins, and perforating veins. All varicose veins are superficial veins; they lie between the skin and a layer of fibrous connective tissue called fascia.

internal jugular and subclavian veins

A sycamore leaf exhibits a palmate vein pattern, characterized by several primary veins that radiate from a central point at the base of the leaf. These main veins branch outwards, resembling fingers extending from the palm of a hand. The secondary veins then further divide, creating a network that enhances the leaf's structural integrity and facilitates nutrient transport. The overall design contributes to the leaf's ability to efficiently capture sunlight and withstand environmental stress.

Valves in the peripheral veins prevent blood from backflow during the off beat of the heart. If not for the valves, the flow of blood would tend to pool at the extremities.
