Gastrointestinal, Nervous, And Circulatory/Lymphatic Systems

ANSWERS

The lymphatic system is a network of specialized vessels and organs whose primary function is to return lymph from the tissues to the bloodstream.
The lymphatic system is a component of both the circulatory and immune systems and is frequently overlooked in textbooks. The lymphatic system’s functions complement those of the bloodstream because it regulates fluid balance and filters pathogens from the blood.

gastrointestinal tract

The organs absorb food and liquids and convert them into substances the body can use for energy, growth, and tissue repair. Waste products that the body cannot use exit the body via bowel movements. The gastrointestinal system comprises the mouth, pharynx (throat), esophagus, stomach, small intestine, large intestine, rectum, and anus. It also contains the salivary glands, liver, gallbladder, and pancreas, which produce digestive juices and enzymes that aid in the digestion of food and liquids—also known as the digestive system.

The nervous system is divided into two parts:

The brain and spinal cord comprise the central nervous system.
The peripheral nervous system includes nerves that branch off the spinal cord and travel throughout the body.
The nervous system is responsible for signal transmission between the brain and the rest of the body, including internal organs. The activity of the nervous system thus controls the ability to move, breathe, see, think, and so on.1

A nerve cell, also known as a neuron, is the basic unit of the nervous system. The human brain has approximately 100 billion neurons. A neuron has a cell body containing the nucleus and particular extensions known as axons (pronounced AK-sons) and dendrites (pronounced DEN-drahytz). Nerves are bundles of axons found throughout the body. Neurons can communicate over long distances thanks to axons and dendrites.
