Hola!
Human skin are made from various tissue.
In us there are four basic types of tissue, That are :
→ Epithelial tissue
→ Muscular tissue
→ Nervous tissue
→ Connective tissue
[ note: There are many sub-tissues in human skin but mainly these four are considered ]
hope it helps!
The sequence of events that will occur are as follows:
- Receptors in her toe receive stimuli.
- The sensory neuron generates an impulse.
- Interneurons relay the impulse to motor neurons in the spinal cord.
- She immediately moves her foot
<h3>What is Nervous System?</h3>
The brain, spinal cord, and nerves make up the nervous system. It greatly affects how you feel and think, as well as how your body behaves. You can walk, speak, swallow, breathe, and learn thanks to it. It also regulates the body's emergency response.
To learn more about the nervous system with the help of the given link:

The cell wall contains not only cellulose and protein, but other polysaccharides as well. The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
The small intestine is the site where almost all of the digestion and absorption of nutrients and minerals from food takes place. ... The inner surface of the jejunum, its mucous membrane, is covered in projections called villi, which increase the surface area of tissue available to absorb nutrients from the gut contents.
The digestive process
The digestive tract -- also called the gastrointestinal tract or alimentary canal -- provides the pathway through which foods move through the body. During this process, foods are broken down into their component nutrients to be available for absorption.
Extra information
Digestion actually begins in the mouth, as the enzymes in saliva begin to break down carbohydrate (starch). As food is chewed, it becomes lubricated, warmer, and easier to swallow and digest. The teeth and mouth work together to convert each bite of food into a bolus that can readily move into the esophagus ("the food pipe"). In the meantime, taste buds located in the mouth help you to enjoy each mouthful -- or to find the food distasteful, as is sometimes the case. After the bolus is swallowed, it enters the esophagus where it continues to be warmed and lubricated as it moves toward the stomach.
The acidic environment of the stomach and the action of gastric enzymes convert the bolus into chyme, a liquefied mass that is squirted from the stomach into the small intestine. Carbohydrates tend to leave the stomach rapidly and enter the small intestine; proteins leave the stomach less rapidly; and fats linger there the longest.
The small intestine is the principal site of digestion and absorption. There, enzymes and secretions from the pancreas, liver, gallbladder, and the small intestine itself combine to break down nutrients so that they can be absorbed. The pancreas is a veritable enzyme factory, supplying enzymes to digest proteins, fats, and carbohydrates. Intestinal cells also supply some enzymes. The liver produces the bile required for the emulsification of fat, and the gallbladder stores the bile until it is needed. The absorption of nutrients in the small intestine is facilitated by tiny projections called villi, which provide more surface area for absorption. The nutrients pass through the intestinal membranes into the circulatory system, which transports them to body tissues. Nutrients are then absorbed into the cells, where they are used for growth, repair, and the release or storage of energy. The overall process -- called metabolism -- is highly complex.
Undigested chyme proceeds from the small intestine into the large intestine (colon), where it becomes concentrated, as liquid is absorbed in preparation for excretion. Bacteria cause fermentation, which facilitates further breakdown, but absorption of nutrients from the large intestine is minimal.
