The adult skeletal system does. The bones allow humans not to be “blobs,” there would be no support to do things like standing, walking, sitting, kneeling or crawling. The skeletal system is made up of connective tissues (bone, cartilage, tendons, and ligaments), blood vessels that run through canals in the bone and muscles to aide in mobility. Bones are considered a type of mineralized connective tissue that contains collagen and calcium phosphate (which gives bones their firmness). Bones provide protection to vital organs. The ribs protect the lungs and the heart and the skull protects the brain. Next there is cartilage it is a type of fibrous connective tissue that is composed of closely packed collagenous fibers and a rubbery gelatinous substance called chondrin. Cartilage provides flexible support for certain structures in adult humans including the nose, trachea, and ears. Tendons are an important part of the system because they connect bone to bone, while ligaments connect muscle to …show more content…
After the body uses all the nutrients it needs solid waste is discarded in the form of feces and the liquid waste in the form of urine. The large intestines of the digestive system handles the solid waste but it is up to the excretory system to rid the body of liquid waste. In the large intestines it was mentioned that water is removed at this point and put back into the circulatory system. This is when the renal arteries bring this waste to the kidneys for cleaning. The cleaned blood travels on and the waste is then sent to the urinary bladder via the ureters. When the urinary bladder expands, it sends a signal to the brain and then urine is passed through the urethra out of the body (Essenfeld,
