“embryonic pulsing”

Seems like that's an awfully convenient way to try and skirt the heartbeat bills...

quote:

---

Or a way to understand the complex issue of an embryo not having a heart. Can you have a heartbeat without a heart?.

---

Can you have an abortion without being pregnant which would ultimately result in the birth of a child if not for said abortion?

Libs and their linguistic semantics... Tale as old as time.

Words have meaning, I know that's difficult for you to understand. Eventually you're gonna have to learn, though.

I have never understood why some people are so easily upset by the use of terminology that is emotionally-neutral and scientifically- and medically-accurate. Baffling.

quote:

---

Embryonic heart pulsation is the earliest proof that the embryo is alive.

---

I don't know about that. I would think that the first evidence of "life" is the point at which an embryo starts to process nutrients and convert those nutrients into further growth. Up to that point, the developing organism is simply cannibalizing materials which were contained in the ovum.

quote:

---

Cardiac pulsation has been documented in utero by transvaginal scanning as early as 36 days menstrual age

---

Yes. Completely accurate.

quote:

---

the time when the heart tube starts to beat

Not entirely accurate. There is a REASON medical science uses different terminology (pulsing) at this stage ... because it IS different (versus "beating").

Of course, it DOES serve the same function.

The embryonic heart is the first functioning organ in the human body (Keller, 2007), and related cardiovascular organs are influenced by the mechanical environment provided by this pulsatile flow, either via shear forces (le Noble et al., 2004) or gradients in pressure leading to circumferential strain in blood vessels (Lucitti et al., 2006). The immediate formation of a primitive heart tube and subsequent chamber, valve, and vascular branching occurs in concert with these mechanical forces (Keller et al., 2007). Confocal microscopy has allowed researchers to look within the developing embryos over time to probe both spatial and temporal patterns resulting from these mechanical roots

You mean the terminology "life begins at conception"? IKR

Or such controversial terms as "male" or "female". So hurtful and hateful.

Do you have any freaking idea how open-ended that is? Ever hear of mold? Fungi?

---

Both of which are “life.”. I do not understand the point you are trying to make.

You DO realize that I said (in essence) that “life” for an embryo begins BEFORE heart activity, right?

Here is the NASA discussion on “life.”

quote:

---

How to define "life" is a sweeping question that affects whole branches of biology, biochemistry, genetics, and ultimately the search for life elsewhere in the universe.

Comparing the semantic task to the ancient Hindu story of identifying an elephant by having each of six blind men touch only the tail, the trunk, or the leg, what answer a biologist might give can differ dramatically from the answer given by a theoretical physicist.

However, some initial agreement is possible. Living things tend to be complex and highly organized. They have the ability to take in energy from the environment and transform it for growth and reproduction. Organisms tend toward homeostasis: an equilibrium of parameters that define their internal environment. Living creatures respond, and their stimulation fosters a reaction-like motion, recoil, and in advanced forms, learning. Life is reproductive, as some kind of copying is needed for evolution to take hold through a population's mutation and natural selection. To grow and develop, living creatures need foremost to be consumers, since growth includes changing biomass, creating new individuals, and the shedding of waste.

To qualify as a living thing, a creature must meet some variation for all these criteria. For example, a crystal can grow, reach equilibrium, and even move in response to stimuli, but lacks what commonly would be thought of as a biological nervous system.
