* Blood cells * Skin cells * Nerve cells (neurons) * Goblet cells (in the lining of the stomach) * Muscle cells * Gametes (female ova or male sperm)Epithelial cells play many very important roles in the human body. they are usually arranged in thin sheets of epithelial tissue and they cover internal and external surfaces. epithelial cells have many different functions, and their basic structure may be adapted to make them more efficient at their job. many epithelial cells are there to protect the tissues underneath from damage or infection.
The stomach is lined with cells, collectively called epithelial tissues. These cells are constantly being replaced and usually complete the cell cycle within 24 hours.
From stage of the cell cycle do cells somtimes exit?
The growth cycle requires _____ to run.
There are many different cells in the human body. The different cells in the body are generally grouped into tissues that have similar properties. The four main groups of tissues in the body are, muscular, nervous, connective, and epithelial. There are 3 classes of cells in the human body. Labile cells, stable cells, and permanent cells. Labile cells are dividing all the time--always in the cell cycle. Examples include cells in the digestive tract, skin, respiratory tract, and stem cells in the bone marrow producing blood cells. Stable cells are in Gap O most of the time in the cell cycle, but can be stimulated to enter the cell cycle when needed. Examples include: the liver, the proximal tubules of the kidney, and endocrine glands. Permanent cells remain in the Gap 0 phase of the cell cycle, and will not come out no matter what!!! RBC's, nervous tissue, cardiac myocytes, and the lens of the eye are examples. Permanent cells cannot be replaced!!
. be in mitosis.
Because epithilial cells usually flakes away.So always have to be replaced.Liver cells do not damaged easily.
The estrous cycle is the cycle of a non-pregnant female mammal that goes through a luteal phase and a follicular phase. Estrus is the period in which an animal will stand to be bred, and is part of the follicular phase of the estrous cycle. An easy way to remember it is that estrous is an adjective and estrus is a noun. Thus, estrous refers to the entire cycle, whereas estrus just refers to the phase in which the animal can get pregnant. Usage: The female chimpanzee can get pregnant because she is in estrus. The female chimpanzee can get pregnant in this phase of her estrous cycle.

Anestrus or Diestrus. Proestrus is when the female is about to go into estrus, and Metestrus is the period before Diestrus and after Estrus which the female goes out of heat and ovulation ends.
The length of estrous for cattle is approximately 21 days. The estrus period last about 18 hours.
ProestrusThe first phase of the estrus cycle begins with proestrus and lasts approximately 9 days. The dog's vaginal area becomes swollen and excretes a bloody discharge during this phase. This is also the phase that is often confused with a menstrual cycle. During this phase the dog's body prepares itself for a possible pregnancy, but the female will not accept the male at this time.EstrusThe second estrus phase also lasts approximately 9 days and this phase is called estrus. During this phase the female ovulates, and she will readily accept a male

She will bleed a little a couple days after estrus.
because it does When she is in her estrus cycle the scent attracts the male.
Most female does have their first estrus cycle between six and twelve months.
