Intestinal Health

Starting from the bottom of the stomach to the anus, the intestines do the work of absorbing what we eat and putting it to good use. When they are working well, we hardly think about them. When they don't, we have questions. Ask them here.

Why is the medication heparin sometimes administered prior to a left-side cardiac catheterization?

Before left-side catheterization is performed, the anticoagulant medication heparin may be administered. This drug helps decrease the risk of the development of a blood clot in an artery and blood clots traveling throughout the body.

Can boiling kill a fungus such as C difficile?

Clostridium diff. is an intestinal (hospital borne) infectious bacterium, so boiling 'in there' is no option, but that wasn't the question, was it?

In general:

Boiling to kill anaerobic spore forming bacteria (like Clostridiaea) is a far from sufficient sterilising method, it only stops (kills) the living cells (not all), it does not stop (kill) the spores from being infectious as new germs. Also toxins are thermo-resistant as far as I know.

What is the explanation for the importance of osmoregulation in body?

Osmoregulation is important in maintaining the balance of water and solutes in the body. It helps regulate cell volume, maintain blood pressure, and ensure proper function of organs like the kidneys. Without osmoregulation, the body would not be able to effectively control hydration levels and electrolyte concentrations, leading to health issues.

What is parietal and visceral?

(1) On February 8, 2012 at 5:57 am Mysandie [0] said:

Learning a little Latin helped me to remember:

  • "visceral" refers to inner
  • "pari" = wall
  • "peri" = around
  • "epi" = upon
  • "endo" = inside
  • "myo" = muscle

Most people think of the pericardium as just a double-layered, membranous sac (The Pericardial Cavity) that is around the heart. But, the pericardium is actually TRIPLE layered: the visceral layer, the parietal layer, and the fibrous layer (fibrosa).

The visceral pericardium is the inner-most layer of the pericardium, and is also known as the Epicardium as it "lays" upon the heart.

The Pericardial Cavity lies between the visceral pericardium and the parietal pericardium. This cavity is filled with pericardial fluid which serves as a shock absorber by reducing friction between the visceral and parietal layers. The parietal pericardium is an outer layering wall of the Pericardial Cavity between the pericardial membranes.

The outer-most layer is the fibrous layer (fibrosa), and contains nerves, blood vessels, and lymphatics. This is the layer that can become inflamed, called pericarditis. (As opposed to, endocarditis, which is inflammation of the insidelayer of the heart.)

Studies the structure of cells to learn how they fuction and interact with chemical and physical factor?

Cell biologists examine the organization and function of cells to understand how they respond to different chemical and physical stimuli. By studying the structure of cells, they can gain insights into various cellular processes and interactions that are crucial for the overall functioning of living organisms.

What is a stronger anti-diarrheal than DiphenOxylate?

Loperamide is a common antidiarrheal medication that is typically stronger than diphenoxylate. It works by slowing down the movement of the gut and reducing the frequency of bowel movements. Always consult a healthcare professional before using any new medication.

Is aspergillus curable?

I think you mean aspergillosis. It's the disease caused by inhaling aspergillus, a type of fungus. And yes, it is treatable. The drugs amphotericin B, caspofungi, flucytosine, intraconazole or voriconazole are used to treat it. In extreme cases, voriconazole and caspofungin are also used combined.

How do you think skin cells are important to other body cells?

Skin cells provide a protective barrier against external pathogens and help regulate body temperature. They also play a role in immune responses by producing antimicrobial peptides and initiating inflammatory responses. Additionally, skin cells communicate with other cells in the body through signaling molecules and support the growth and repair of neighboring tissues.

What hormone initiates sperm production?

The hormone that initiates sperm production is called follicle-stimulating hormone (FSH). It is produced by the pituitary gland and stimulates the testes to produce sperm in males.

How does giardiasis move?

Giardiasis is caused by a parasite called Giardia lamblia, and it is typically transmitted through contaminated water or food. The parasite is ingested and then spreads to the small intestine where it reproduces and causes symptoms such as diarrhea and other gastrointestinal issues. Proper hygiene, such as washing hands thoroughly and purifying drinking water, is important in preventing the spread of giardiasis.

Organelle that functions as a protein factory is what?

The organelle that functions as a protein factory is the ribosome. Ribosomes are responsible for protein synthesis in the cell by decoding the messenger RNA (mRNA) and assembling amino acids into polypeptide chains.

Function of uterus of the frog?

The uterus of a frog is responsible for receiving and storing fertilized eggs until they develop into tadpoles. The uterus provides a protected environment for the eggs to develop before they are expelled into the water as fully formed tadpoles.

Does filtered water by a UV water system leave dangerous dead particulate in the water or is that just with boiled water?

A UV water system disinfects water by inactivating microorganisms like bacteria, viruses, and protozoa without leaving any dead particulates. Boiling water kills microorganisms by heat but does not remove any dead particles, which may still be present in the water.

Does everyone in the world defecate?

Only if you drink anything and eat food.

If you are pregnant but haven't eaten anything or drink

you will need the toilet.

What quadrant is the gall bladder in?

The left upper quadrant is the location of the left portion of the liver, the larger portion of the stomach, the pancreas, left kidney, spleen, portions of the transverse and descending colon, and parts of the small intestine. The upper light contains the rest of the stomach.

What do you call organisms that break things down into nutrients?

Scavengers. Organisms that break things down into nutrients is called Matter.

Look up in the dictionary the meaning or meanings and you will understand better.

Increasing the surface area between solute and solvent increases what?

Increasing the surface area between solute and solvent increases the rate of dissolution, as it provides more contact for the solute molecules to interact with the solvent molecules. This can lead to a faster dissolution process and a more efficient mixing of the solute in the solvent.

What is the effect of air on food spoilage?

Air promotes food spoilage by providing oxygen for the growth of aerobic bacteria and fungi. It also allows for oxidation of fats and oils, leading to rancidity in foods. Vacuum sealing or storing food in airtight containers can help prevent air exposure and prolong the shelf life of food.

What organ digests proteins?

The stomach is the main organ responsible for digesting proteins. It secretes enzymes like pepsin and hydrochloric acid to break down proteins into smaller peptides and amino acids for absorption in the small intestine.

Is it possible to see slightly brighter colours in one eye than the other without any eye disease?

Yes, it is possible to perceive slightly brighter colors in one eye compared to the other even without any eye disease. This can be due to variations in the light sensitivity of each eye or differences in the cones in the retina, which detect color. It is not necessarily a cause for concern unless it is accompanied by other symptoms or changes in vision.

What does the uterus do in a fetal pig?

Umbilical cord - The flexible cordlike structure connecting a fetus at the navel with the placenta and containing two umbilical arteries and one vein that transport nourishment to the fetus and remove its wastes.

What is receptor desensitisation?

Receptors generate a cellular response upon binding their specific ligand. This response can vary in magnitude. Desensitisation is a phenomenon in which activation of a receptor can reduce the magnitude of the response if it is subsequently activated again. Usually the longer a receptor is activated for the greater the desensitisation will be.

There are 3 general mechanisms as to how desensitisation occurs. The first is uncoupling of the receptor from proteins which generate the cellular response. The second is internalising receptors so that they cannot be activated. The third is reducing production of receptors so less are available. In general mechanism 1 is short term, 2 is mid-term and 3 is long term.
