What is the biggest organ in the bodyliver or skin?
Skin is actually the largest organ. It covers your whole body, and no other organ is bigger than that.
Is the adipose tissues found in the dermis of the skin?
As far as I know they are in the epidermis, so no.
There are two types of sweat glands on the skin: apocrine â?? found mainly in the armpit area â?? and eccrine glands, which are found all over the skin surface. The mechanism of sweating, is controlled by the bodyâ??s autonomic nervous system
What does The epidermis contain that allows it to provide a protective physical barrier?
The dermis contains fat cell, blood supply, and nerves. It also contains hair follicles, oild glands, and sweat glands. Fibroblasts in the dermis make collagen.
The dermis is composed of connective tissue and contains blood vessels, nerve endings, hair follicles, lymph vessels sebaceous glands(oil glands), and sudoriferous glands(sweat glands).
collagen fibers, arector pili, sebaceous glands, sudoriferous glands, sensory receptors pacinian corpuscle, meissener's corpuscle, hair root, stratified epithelium The dermis contains, among other things, hair follicles, sebaceous glands (oil), sweat glands, free nerve endings (pain), pressure/touch receptors and a microvascular supply.
Why is it important to carry out skin analysis?
i do notice :-
wrinkles
colour
hairy skin or not
how many black spots
and much
Which accessory organs of the skin are affected by acne?
the things that affect acne are hot water and soap or you can use a chemical product
What is the treatment for cutaneous larva migrans?
Thiabendazole or albendazole are used to treat the infestation. Mild infections can be treated by applying one of the drugs to the skin along the tracks and the normal skin surrounding the area.
What part of the skin releases sweat?
Sweat is used to cool off your body- whether that extra heat comes from hardworking muscles or from overstimulated nerves, your body will produce tiny droplets of water to cool off.
The average person has about 3 million sweat glands in the layer of skin called the dermis along with nerve endings and hair follicles.
What is the protein in the epidermis that thickens and protects the skin called?
The protein in the epidermis that thickens and protects the skin is called keratin. It is a fibrous structural protein that forms a protective barrier, helping to prevent water loss and protect against environmental damage. Keratin is a key component of hair, nails, and the outer layer of skin.
Does skin turn blue when it does not get oxygen?
Blood in the arteries is bright red, blood in the veins is dark red mostly from the impurities that are being carried back to the kidneys and liver for disposal that are mixed in and brownish which darkens the red color to more maroon. Blood in veins can look "blue" when viewed through the skin because of light refraction and other factors. But the blood is red and the veins are actually white.
When a person donates blood, it comes from a vein, not an artery. It is also not exposed to air, or it would be contaminated and need to be disposed of. It also happens to be dark red, NOT blue.
The common misconception of "blue" blood is continued due to textbook illustrators use of blue and red to differentiate arteries and veins. Venous blood is actually a burgundy or maroon color.
An Optical Illusion
The reason we see blue is more into the optics side of science. It is really because of how light reflects on our skin, and the way different wavelengths piece through our skin with different effectiveness.
The veins you see through your skin appear blue because red light goes through the skin much more easily (and thus more) than blue light. The red light is absorbed, and the blue is reflected. Optical scientists also believe that the eyes see more of the blue color than the red.
A vein is just a tube blood travels through when returning to the heart and lungs after depleted of nutrients and oxygen, the neutral color of a vein itself doesn't change the color of the blood.
It is not the blood but the veins that "look" blue, and even then it is not the actual color of the vessel. The difference is in the way colored light moves through the tissues, and how the eye perceives those colors of light.
The oxidation state of the iron in the hemoglobin also affects the color but only slightly and not as much as the wastes carried in the veins do.
Some factor of the changes in blood coloration do relate to the respiratory pigment, hemoglobin. Hemoglobin is a topologically complex molecule that very readily binds to oxygen. Once the molecule is fully saturated, it reflects in the crimson red spectrum, and therefore fully oxygenated blood appears to be bright red. After the hemoglobin molecule gives up its oxygen to tissue that needs it, the molecule becomes much less reflective, and with the added wastes the venous blood carries, the returning blood appears very dark red to purple. However, it is more the addition of wastes that impacts the darkened color, not so much the change in oxygen content.
As mentioned above, blue is often used in illustrations in charts and diagrams of the circulatory system and vessels to contrast against red, with usually red representing the arterial system bearing O2 and blue being the "deoxygenated" blood in the venous system. However, this tradition of using these colors is just that: tradition. It is not based on actual blood color. The colors could just as easily be shown as yellow or green for the purposes of the illustrations to show blood flow.
The reason why only veins appear blue to your eye is because they are the most superficial to the skin and therefore seen through the skin. Arteries can not be seen because of how deep they are in the body (a protective mechanism of our bodies). The color blue/violet is the highest frequency of the visible light scale; it therefore has the most penetrating power to be seen through skin, fat, etc. Red is low frequency and is filtered out by skin and fat, which is why it cannot be seen.
Science Project: If you took a red diode light and put it in milk, it would appear blue in color because milk filters the red out much like our fat/skin. Try it and see!
What color skin would Egyptians have?
There is more than 1 ethnic ( race or ethnicity) group In Egypt. Egyptian people are a mixed diverse ethnic group of people. But they are all the exact same race. But it really depends on what descendents the person carries. If the person is from Southern Egypt them he would be very dark that also includes Frizzy hair, large nose and lips just like Black Africans do ( I'm not racist). And Southern people of Egypt carry a more African Sudanese ancestry. While In most places in Egypt have Arabic culture and People who have colored eyes and have blonde,or any colored hairs exept black either have a Turkish/European ancestry. But in skin color it is tan,brown,dark brown,light brown,light olive,dark olive,pale,and fair skin. Egyptians come in all colors. Egyptians have skin colors Indians from India have. Most Egyptians have Arabic Ancestry so it would most likely be either Fair or Tan.
What is the purpose by sebaceous glands?
because they secrete sebum
Sebaceous glands are oil glands that are in the hair follicles in our skin.
The function of Sebaceous Glands is to produce an oily secretion, called sebum, which is your skin's natural lubricant.
Sevaceous glands contain groups of specialized epithelial cells and are usually associated with hair follicles. They are holocrine glands that secrete an oily mixture of fatty material and cellular debris called sebumm through small ducts into the gair follicles. Sebum helps keep the hair and skin soft, pliable, and waterproof.
It secretes sebum.
because they produce oil that would keep our skin lubricated and protected Sebaceous glands produce oils to lubricate the skin. Produce oil to the lubricate the skin
The sebaceous glands produce an oily fluid called sebum that helps keep hair and skin soft and regulates body heat by controlling the evaporation rate of perspiration.
What tool will you use to separate the skin from the muscle layer?
so, a frog has 2 layers of skin and what do you use to separate the skin from the muscle?
Yes, it can. In James Bond: Goldfinger, one of the actresses set to play a golden girl actually died from suffocation in her changing room after being painted from head to toe in gold paint. Her major airways (nose and mouth) were unobstructed and there was no sign of foul play. After that accident, paint was applied to everywhere visible by camera. This way, the women's backs could be left unpainted, thus, suffocating was prevented. So, yes, oxygen osmosis does happen and it is vital to survival.
How often do you replace your epidermis layer of skin?
Your skin sheds every 28-45 days, rejuvenating the epidermis and allowing the next generation of skin cells to come forward. The dead skin needs to slough off to allow the new cells to the top. We shed about 40 lbs of skin in a lifetime!
The volar skin refers to the skin on the palm of the hands and the soles of the feet. It is characterized by its thicker, tougher texture compared to other skin areas, as it needs to withstand friction and pressure from activities such as gripping and walking. This skin contains more sweat glands and fewer hair follicles, contributing to its unique properties and functions. The volar skin also plays a crucial role in providing tactile sensitivity and grip.
