The Ureters - Anatomical Course - Neurovascular Supply -TeachMeAnatomy
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. is made of skeletal muscle and may be opened to allow urine to pass through. Calcium is not only the most abundant mineral in bone, it is also the most and the interactions of the skeletal, endocrine, digestive, and urinary systems. The kidney and urinary systems help the body to eliminate liquid waste called urea, and to keep This controls red blood cell production in the bone marrow.
If urine backs up, or is allowed to stand still, a kidney infection can develop.

About every 10 to 15 seconds, small amounts of urine are emptied into the bladder from the ureters. This triangle-shaped, hollow organ is located in the lower belly. It is held in place by ligaments that are attached to other organs and the pelvic bones.
The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra. The typical healthy adult bladder can store up to 2 cups of urine for 2 to 5 hours. Nerves in the bladder. The nerves alert a person when it is time to urinate, or empty the bladder. This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten. Lymphatic System The lymphatic system protects the body from infection.
Adenoid, tonsils, thymus, lymph nodes, spleen The brain can stimulate defense mechanisms against infection. Respiratory System The respiratory system supplies oxygen to the blood and removes carbon dioxide. Lungs, larynx, pharynx, trachea, bronchi The brain monitors respiratory volume and blood gas levels. The brain regulates respiratory rate.
Digestive System The digestive system stores and digests foods, transfers nutrients to the body, eliminates waste and absorbs water. Stomach, esophagus, salivary glands, liver, gallbladder, pancreas, intestines Digestive processes provide the building blocks for some neurotransmitters. The autonomic nervous system controls the tone of the digestive tract. The brain controls drinking and feeding behavior. The brain controls muscles for eating and elimination.

The digestive system sends sensory information to the brain. Reproductive System The reproductive system is responsible for producing new life. Testes, vas deferens, prostate gland, ovary, fallopian tubes, uterus, cervix Reproductive hormones affect brain development and sexual behavior. It churns food and mixes it with various lubricating and digestive secretions.
The Small Intestine, liver, gallbladder, and pancreas The duodenum is the first section of the small intestine. It is about 10 inches long. The jejunum is the second section of the small intestine, further enzymes are secreted here, which aid digestion.
The ileum is the longest section of the small intestine, where the bulk of food absorption takes place. Absorption of nutrients etc. The liver is the largest gland in the body weighing about 3 lbs. It is a gland in the sense that it secretes BILE. It is also essential in the Metabolism of proteins, fats and carbohydrates.
The gallbladder stores bile secreted by the liver until needed in the ileum. The pancreas is a long narrow, lobed gland that is located behind the stomach.
Once food is absorbed in the ileum, the residue is passed into the large intestine. This is between five and six feet long! The caecum lies between the ileum and the colon. The appendix is attached to the caecum, the appendix no longer serves any real function and can be removed without any ill effects. The colon is divided into four sections: Once the excess water which is a by-product of digestion has been absorbed by the colon the solid waste is passed to the rectum.
