the rumbling noise caused by the movement of gas in the intestine is known as _____.
The rumbling noise caused by the movement of gas in the intestine is known as stomach rumble.
A stomach rumble, additionally called a bowel sound or peristaltic sound, is a rumbling, growling or gurgling noise produced with the aid of using motion of the contents of the gastro-intestinal tract as they're propelled via the small gut with the aid of using a sequence of muscle contractions known as peristalsis. Your belly simply made a growling sound known as borborygmus. That's due to the fact while the muscle groups for your digestive device circulate food, liquid, and gas via your belly and small gut, it produces a rumbling sound.

Secretions through a duct might provide ________, whereas ductless secretions act as ________.A) lubrication; lubricatorsB) enzymes; hormonesC) transport media; physical protectorsD) superficial relief; interstitial fluidE) odors; alarms
Secretions through a duct might provide enzymes, whereas ductless secretions act as hormones.
Because they discharge their secretions directly into the circulation rather than into any tubes or ducts, endocrine glands are sometimes known as "ductless glands." The primary glands that make up the human endocrine system are the hypothalamus, pituitary gland, pineal body, thyroid, parathyroid, adrenal, pancreatic, and gonad glands.
The two adrenal glands, the spleen, the thyroid, the pituitary, the thymus, and the pineal gland are all ductless glands. An exocrine gland is a different category of gland (e.g. sweat glands, lymph nodes). Due to the fact that they don't manufacture hormones and discharge their output through a duct, they are not regarded as being a component of the endocrine system.

The term heterotroph refers to an organism that:
a. Must obtain organic compounds for its carbon needs
b. Does not need a carbon source
c. Gets energy from sunlight
d. Uses CO2 for its carbon source
The heterotroph is an organism that must obtain organic compounds for its carbon needs (option B)
Heterotrophic organisms are those that are dependent on plants or other organisms for sustenance since they are unable to produce it on their own. Heterotrophs include all mammals, protozoans, fungi, and the majority of bacteria. Every living thing needs a supply of carbon in the form of lipids, carbs, and proteins since they are necessary for energy. Heterotrophs get their carbon from organic substances, typically from plant or animal matter.
Any organism classified as a heterotroph requires organic substances as a carbon source for the synthesis of its own cellular constituents. Organisms can be categorized as photoheterotrophs or chemoorganotrophs based on their energy source. Reduced organic molecules are a common source of carbon and energy for chemoorganotrophs.

D) A salt such as NaCl is formed by an ionic reaction. 21) Which of the following would be a proposed mechanism by which stomach antacids work? A) Antacids are bases and by definition can absorb OH- out of a solution. B) Antacids are bases and by definition can absorb H+ out of a solution. C) Antacids dilute the solution, therefore lowering the pH. D) Antacids contain mostly water and so they neutralize the solution.
Ions are formed by losing or gaining electrons, so they have more or fewer electrons than non-ionic atoms of the same element.
For example, Na has 11 electrons, while the Na+ ion was created by losing one electron, so it has 10 electrons.
Antacids are drugs to relieve symptoms due to stomach ulcers or stomach acid. Antacids are alkaline and neutralize the acid produced in the stomach, reducing acidity.

The counter-regulatory functions of the pancreas refer to the fact that it releases one hormone that reduces glucose levels in the blood and another that increases them. Here option B is the correct answer.
The pancreas is an organ that plays a crucial role in maintaining glucose homeostasis in the body. It releases two hormones, insulin, and glucagon, that have opposite effects on glucose levels in the blood.
Insulin is a hormone that promotes the uptake and storage of glucose by cells, while glucagon promotes the breakdown of glycogen and the release of glucose into the bloodstream. These two hormones work together to keep blood glucose levels within a normal range and are referred to as the counter-regulatory hormones.

Which hormones are directly involved in cardiovascular activity?
The hormones directly involved in cardiovascular activity are epinephrine, norepinephrine, angiotensin II and vasopressin.
Epinephrine is released during times of stress or excitement, which increases heart rate and stimulates the breakdown of stored energy.
Norepinephrine also helps to regulate blood pressure and stimulate energy production.
Angiotensin II helps to constrict blood vessels, causing an increase in blood pressure by narrowing their diameter to reduce overall volume flow.
Vasopressin is a hormone which also contributes to elevations in blood pressure as it binds to receptor sites on the smooth muscles of smaller arteries, resulting in their constriction.
