It permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous. Together with the skeletal system it forms the musculoskeletal system, which is responsible for movement of the human body.

The integumentary system includes hair, scales, feathers, hooves, and nails. It has a variety of additional functions; it may serve to waterproof, cushion, and protect the deeper tissues, excrete wastes, and regulate temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperatureThe integumentary system in the human beings consists of the skin, hair, nails, glands, and nerves. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.]]> 2018-10-29 09:36:59 UTC https://padlet.com/r_saprio/thesystems/wish/297920175 1 The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. r_saprio https://padlet.com/r_saprio/thesystems/wish/297922256 2018-10-29 09:45:16 UTC https://padlet.com/r_saprio/thesystems/wish/297922256 2 Your digestive system is uniquely designed to turn the food you eat into nutrients, which the body uses for energy, growth and cell repair. Here's how it works.The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.Throat Also called the pharynx, the throat is the next destination for food you've eaten. From here, food travels to the esophagus or swallowing tube. The Esophagu is a muscular tube extending from the pharynx to the stomach. By means of a series of contractions, called peristalsis, the esophagus delivers food to the stomach. Just before the connection to the stomach there is a "zone of high pressure," called the epiglottis; this is a "valve" meant to keep food from passing backwards into the esophagus.StomachThe stomach is a sac-like organ with strong muscular walls. The stomach secretes acid and powerful enzymes that continue the process of breaking down the food. When it leaves the stomach, food is the consistency of a liquid or paste. From there the food moves to the small intestine.Small Intestine is made up of three segments, the duodenum, jejunum, and ileum, the small intestine is a long tube loosely coiled in the abdomen .The small intestine continues the process of breaking down food by using enzymes released by the pancreas and bile from the liver. Bile is a compound that aids in the digestion of fat and eliminates waste products from the blood. Peristalsis (contractions) is also at work in this organ, moving food through and mixing it up with digestive secretions. The duodenum is largely responsible for continuing the process of breaking down food, with the jejunum and ileum being mainly responsible for the absorption of nutrients into the bloodstream. r_saprio https://padlet.com/r_saprio/thesystems/wish/315435190 2018-12-18 08:24:14 UTC https://padlet.com/r_saprio/thesystems/wish/315435190 3 While food is in the small intestine, nutrients are absorbed through the walls and into the bloodstream. What's leftover (the waste) moves into the large intestine (large bowel or colon).The colon (large intestine) is a five- to seven -foot -long muscular tube that connects the small intestine to the rectum.The appendix is a small tube attached to the ascending colon. The large intestine is a highly specialized organ that is responsible for processing waste so that defecation (excretion of waste) is easy r_saprio https://padlet.com/r_saprio/thesystems/wish/321148248 2019-01-16 10:20:42 UTC https://padlet.com/r_saprio/thesystems/wish/321148248
