2.11. CVA = cerebral vascular accident; stroke

Blood, like human emotion, doesn't do well when blocked or overflowing everywhere. Most people still use the term, "stroke," for the third leading cause of death in the U.S. (after heart disease & cancer), though for awhile the National Institutes of Health (NIH) was trying to make the phrase, "brain attack," happen.

During a heart attack, part of the heart doesn't get enough blood/oxygen, starts freaking out, and cells might die. When a brain attack or stroke happens, part(s) of the brain don't get enough blood/oxygen, or maybe a blood vessel ruptures. Either way, call an ambulance, because time = brain cells.

If someone exhibits sudden numbness/weakness of the face, arm or leg, esp. on one side; experiences sudden confusion; suddenly has trouble speaking or understanding; has a sudden severe headache with no known cause; suddenly has trouble seeing in one or both eyes; or has sudden trouble with walking or balance, call 911 immediately (as opposed…

2.10. V = virus, or vampire blood*

Viruses and vampires have several things in common.
1. They're parasitic. 
Vampires, according to Bram Stoker, folklore, and popular culture, live on human blood, fresh or synthetic, depending on your source. Viruses similarly cannot metabolize nutrients or reproduce on their own and instead rely on a host cell (hijacked by the virus) to make new viruses.

2. They're not alive.
Vampires are both not alive and undead at the same time, however that works. Viruses are also not alive, because they are inanimate, complex, organic matter, bits of protein and DNA or RNA that can't be killed because one can't kill something that was never alive, just like one can't kill a tetrahedron of cement with some tangled-up string inside.

3. They can spread.
Depending on what literature you read or what show/movie you're watching, vampires can "make" other vampires through various means--the traditional blood transfusion/ingestion method; some combination of sucking-dry, b…

2.9. HTN = hypertension, high blood pressure

A little tension in life keeps things interesting, but if the pressure increases too much, something (like a blood vessel, or relationship,) might blow up.
A base level of stress improves focus, while too much stress leads to tunnel vision and helplessness. Hypertension in the brain can cause problems with memory and understanding (due to reduced blood flow to brain cells), an aneurysm (localized enlargement of artery), or dementia (from chronic lack of blood flow to the brain).

The sympathetic nervous system dilates pupils so one can see better in a dangerous situation, but long term hypertension will damage blood vessels behind the eyes and lead to vision problems.

Our hearts beat faster and circulate more blood when we're excited, aroused, etc., nothing wrong with that, but if that tension persists, the hardworking left ventricle might grow thick and ineffective, and eventually fail. Damage and inflammation in arteries from high blood pressure can also lead to a heart attack or…

2.8. Cotyledon = embryonic leaf, or placental lobe

Religious or folk tales and heavy-handed symbolism aside (forbidden fruit, Snow White, One Tree Hunahpu), human mothers are like plants in many literal and practical ways.

They have ovaries, petals of sorts, and buds.

They each have special vascular systems for transporting the fluid that supplies gases and nutrients necessary for life.

They respond to seasons and have cycles. They are part of larger life cycles, and take part in a grand, ecological cycle as well.

They have cotyledons. Human cotyledons are plump, vascular lobes of maternal placenta. Plant cotyledons, two green halves of a split pea or edamame, are the food their mothers packed them so they could eat and grow.

Like plants making our atmosphere habitable and magically creating sugar out of simple ingredients, through the placenta mothers supply O2 and glucose for baby to use and help get rid of baby's CO2 and waste products.

They need water to live and function.

They are endlessly resilient at every stage of life, b…

2.7. Gravida = a pregnant woman

There is such a thing as being a little bit pregnant, presumably pregnant, or probably pregnant before one is positively pregnant. Cis men can have hysterical pregnancies (Couvade syndrome), while a positive pregnancy test could be the result of medications or a (non-pregnancy-related) medical condition.

Presumptive Signs of Pregnancy: "presumptuous" signs perceived by the woman may be caused by just about anything other than actual pregnancy.
1. Absence of menstruation: could be stress, very low or high body weight, excessive physical activity, just late, or menopause.
2. Nausea & vomiting: stress, food poisoning, overindulgence/ having too much fun (without occurence of conception).
3. Breast changes: PMS.
4. Fatigue: anemia, sleep deprivation, or does one need a reason to be tired? How about being a woman in the first place and having to worry about all of this, and everybody else, too?
5. Urinary frequency: possible UTI, or too much liquid, …
