Capillaries

Maggots are larval flies and feed on necrotic tissue -- ie, dead tissue. This is why you don't hear of maggot infections in live humans; larval flies do not feed on living tissue. Generally, the only time that maggots will be found on living things is when said host has some sort of serious injury or wound that is festering or gangrenous. But, even in these cases, it is the festering necrotic tissue that is being eaten, and not the living tissue. In fact, it is precisely this ability to eat rotting tissue, while preserving living cells that makes the maggot useful for medical purposes. In areas of the world that are technologically impoverished, larval flies may be deliberately applied to wounds to clean them; this poses no danger.

So, any fear of being eaten alive by maggots is unfounded and unjustified. If they are ingested, one's body would digest them as any other foodstuff. It would be unlikely that they could enter the human body in any other way.

There are, however, numerous parasitic worms that could inhabit a human host; the most obvious (and easily detectable) would probably be the common pin worm, which looks nearly identical to a maggot; Pin worms are an intestinal parasite, and can readily be observed when they are secreted in the stool of an infected person. This seems the most likely reason for the posting of this question. These are not larval flies (insects), but rather actual worms, and similarly pose no serious risk to the host; they are most common in elementary school children, who are in close contact with each other without handwashing, etc. Usually, the only symptom for young children is restless sleep, as the worms are nocturnal and more active at night, causing annoying rectal itching. Older children or adults will likely notice the tiny worms in their stool eventually, and make inquiries. They are extremely common in the third world, though frequently appear in the U.S. and other developed areas. One's physician can treat them with a single dose of any number of wormicides.

In any case, don't panic... although upsetting and revolting in the extreme (to our Western sensibilities), it's really not a very big deal. Call your doctor.

The right pulmonary veins carry oxygenated blood from the right lung to the left atrium of the heart. This blood then enters the left ventricle before being pumped to the rest of the body to deliver oxygen and nutrients.

The shrinkage crack can be controlled by maintaining the mould temperature at the crack point by reducing the cycle time, improving the sparay pattern, adding gates, using oil lines for heating purpose.

60,000 miles, or the equivalent of 2½ times around the world!

There is no vein that connects directly to the right ventricle. The inferior and superior vena cava enter the right atria and the pulmonary artery leaves the right ventricle.

Ether

'This line is filled with ether gas, so if you have ever broken or cut one and get a funny smell or some white fluid on you, don't worry, it is not harmful'.

Arteries have the largest diameter, then arterioles, and last, capillaries.

Capillaries pick up carbon dioxide from the cells of the body and deliver oxygen.

true

The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps

Capillaries are the smallest blood vessels. They connect arteries and veins. They are the site of gas, waste, and nutrient exchange between the blood and the body tissues.

Capillaries in the small intestine absorb nutrients from the digestive tract. Capillaries in the small intestine also bring oxygen and carry away waste from the intestine.

no. they contract and open due to oxygen demand and some circulating messenger chemicals in the blood like epinephrine (adrenaline- you get nervous and your hands get clammy b/c of this)

A capillary time, or capilllary refill time is how long it takes for your capillaries to refill. The best way to test this squeeze the tip of your finger, then let go. Time how long it takes to go from white to normal color. So a 6 second capillary time is one in which this takes 6 seconds Normally it should happen fairly quickly In the medical world anything over 2 seconds is bad

Items like eggshells and some types of balloons have very thin walls that can be easily damaged. Eggs, for instance, have a fragile shell that can crack with minimal pressure. Similarly, balloons can burst with a small puncture or excessive stretching. Both are examples of structures that require careful handling due to their delicate nature.

To allow the rapid and efficient transfer of oxygen and nutrients (glucose, electrolytes) from the circulation into the nearby cells, and transfer the carbon dioxide and waste products out of the cell back into circulation.

Substances that can exit the blood include oxygen, carbon dioxide, nutrients, waste products, and hormones. These substances move across the capillary walls through processes like diffusion and filtration. Oxygen and nutrients typically exit into tissues to support cellular functions, while waste products like carbon dioxide are transported back into the blood for excretion. This exchange is crucial for maintaining homeostasis in the body.

Increased capillary filtration hyperemia and swelling in a localized area indicate enhanced blood flow and fluid accumulation, often due to inflammation or tissue injury. This process is typically a response to various stimuli, such as infection, injury, or irritants, leading to vasodilation and increased permeability of blood vessels. The resultant edema is part of the body's healing response, facilitating the delivery of immune cells and nutrients to the affected tissues.

Pure diffusion ...

everything flows from high concentration toward low.

No energy is expended in these exchanges.

Capillaries can leak due to various factors, including increased blood pressure, inflammation, or damage to the endothelial cells that line the capillaries. Conditions such as infections, allergic reactions, or certain diseases can also disrupt the tight junctions between endothelial cells, allowing fluid and proteins to escape into surrounding tissues. Additionally, factors like hypoxia and certain toxins can compromise capillary integrity, leading to leakage.

This is because blood is flowing to an area that the body is trying to protect from damage.
