Integumentary System (skin)

The effect of uranium on skin depends from: chemical form (fluoride, metal, nitrate, etc.), physical form (solid, liquid-solution, gas), quantity, time of contact, particles dimensions, etc. Uranium metal (natural isotopic composition) in bulk form is not so dangerous.

One type of hard thick patch of skin is a corn. Corns develop on the feet, particularly on the toes. Another type of hard thick patch of skin is a callus. Calluses usually develop on the feet and the hands.

An embalmer's job is to drain the body's blood and fluid as part of the embalming process, which helps preserve the deceased's body for viewing.

The outermost layer of the skin, called the stratum corneum, contains mostly dead cells called corneocytes. These cells are constantly being shed and replaced with new cells from the underlying layers of the skin.

The skin is mainly composed of two types of cells: keratinocytes, which produce the protein keratin for strength and structure, and melanocytes, which produce melanin for skin pigmentation and protection from UV radiation. Other cell types found in the skin include fibroblasts, immune cells, and sweat and oil glands.

The integumentary system consists of three main layers: the epidermis, dermis, and hypodermis. The epidermis is the outermost layer and provides protection, the dermis is the middle layer containing blood vessels and nerves, and the hypodermis is the deepest layer made up of fat and connective tissue.

Yes, your skin will grow back. The outer layer of your skin is constantly replenishing itself through cell regeneration, so the damaged skin will eventually heal and be replaced by new skin cells as part of the natural healing process. Be sure to keep the area clean and protected while it heals to promote optimal skin regeneration.

Polymers can help the human body by being used in medical devices such as implants and prosthetics, drug delivery systems, and tissue engineering scaffolds. They can be designed for specific functions like controlled release of drugs, biocompatibility, and mechanical strength to support and enhance the body's natural functions.

The integumentary system, which includes the skin, helps with thermoregulation by regulating body temperature through processes like sweating and shivering. Additionally, the cardiovascular system plays a role in thermoregulation by adjusting blood flow near the skin to help dissipate or conserve heat.

Churning of the body usually refers to a feeling of discomfort or unease in the stomach, often accompanied by bloating, gas, or indigestion. It may be caused by various factors such as overeating, consuming rich or spicy foods, or digestive issues. It is important to identify the underlying cause and address it accordingly to alleviate this sensation.

The epidermal cells that are actively mitotic and replace superficial cells are found in the stratum basale, also known as the basal layer or stratum germinativum.

a seed coat, storage tissue, and a dormant embryo. the seed coat protects the seed from drying out, endosperm is the temporary food supply and the cotyledon is the embryo.

Careers associated with the integumentary system include dermatologists, estheticians, skin care specialists, and dermatopathologists. These professionals focus on diagnosing and treating conditions related to the skin, hair, and nails. Additionally, roles such as cosmetic chemists and skincare product developers also contribute to the industry.

Common tumors found in the cardiovascular system include cardiac myxoma, angiosarcoma, and atrial septal defect. In the integumentary system, common tumors include basal cell carcinoma, squamous cell carcinoma, and melanoma.

In human skin cells produced by mitosis, there are 46 pairs of chromosomes, totaling 92 individual chromosomes. This is because each pair consists of one chromosome from the mother and one from the father.

· Lungs o Get rid of CO2. o Lose water vapor (Incidental loss: because it is unavoidable and is not a method of controlling the water content of the body.) · Kidneys o Remove urea and other nitrogenous waste from the blood o Expel excess water, salts, hormones and drugs. · Liver o Excretes bilirubin with the bile to the small intestine to later be expelled with the feces. · Skin o Expels water, sodium chloride and urea during sweating. (Incidental loss: because sweating is a response to a rise in temperature and not to a change in blood compostion.)

Dolphins have smooth skin that feels like rubber. Because their skin is slippery, water flows easily around it. To keep their skin smooth, dolphins shed it constantly. Dolphins have a special layer of fat under their skin called blubber. Blubber acts like a winter coat and keeps dolphins warm in cold water. Dolphins that live in the cold water often have a thicker layer of blubber than those that live in warmer waters. Blubber is also light and helps keep dolphins from sinking while they swim a little bit like an inner tube.

The epiglottis is a flap of tissue that closes over the trachea when we swallow to prevent food and liquids from entering the airway. Its main function is to direct food and liquids into the esophagus, which leads to the stomach, instead of the trachea, which leads to the lungs.

There are approximately 2 to 5 million sweat glands in the human skin. These glands are responsible for regulating body temperature by producing sweat, which evaporates and cools the body. Sweat glands are found throughout the body, with higher concentrations in areas like the palms, soles, and armpits.

It is only eating your dead skin cells so it is not harming your live skin cells. Technicality, it's benefitting you - the problem arises when mites start living in your mattress and pooping. Many people are allergic to mite waste.

I think it's more like 80%. I'm not really sure though.

**Edit**

Sadly this is incorrect.

This is one of those "Eww! Gross!" factoids that sound very scientific, but isn't really true. Sometimes a specific percentage of dust is said to be skin, usually about 70 or 80 percent, but unless you're a molting bird or reptile (or you work in Dr. Frankenstein's laboratory), very little of your environment is composed of dead body parts.

There are far more common sources of dust pollutants, including animal dander, sand, insect waste, flour (in the kitchen), and of course lots of good, old-fashioned dirt.

Every time we open a window or a door, we stir up and move around tiny, airborne particles that eventually settle around the house. Humans do shed dead skin, but most of it is carried away by water when we shave or bathe, ending up not on our floors but in our sewers. Now don't you feel better?

there are 46 chromosomes in a human skin cell.

Bacillus Subtilis is a common rod shaped bacteria which is found in abundance in air, water, soil and decomposing plants. It can temporarily inhabit human skin and gastrointestinal tract of humans upon human contact with surface or medium that is being colonized by the said bacteria.

I screwed up-- the first person had it right. Here's their answer: "A protein is composed of several amino acids chained together - so no melanin is not a protein. Melanin is formed from the amino acid Tyrosine and is NOT a chain of amino acids thus it is not a protein nor is it a amino acid."

Each human skin cell has 46 chromosomes, which are organized into 23 pairs. This includes one set of 23 chromosomes inherited from the mother and another set of 23 chromosomes inherited from the father.
