The urinary system consists of two kidneys, two ureters, a urinary bladder , and a urethra. The kidneys alone perform the functions just described and manufacture urine in the process, while the other organs of the urinary system provide temporary storage reservoirs for urine or serve as transportation channels to carry it from one body region to another. The kidneys, which maintain the purity and constancy of our internal fluids, are perfect examples of homeostatic organs. The urethra is a thin-walled tube that carries urine by peristalsis from the bladder to the outside of the body. Every day, the kidneys filter gallons of fluid from the bloodstream. The normal physiology that takes place in the urinary system are as follows:. In 24 hours, the marvelously complex kidneys filter some to liters of blood plasma through their glomeruli into the tubules.
Human Eye: Anatomy, parts and structure
The names of the cranial nerves relate to their function and they are also numerically identified in roman numerals I-XII. There are twelve cranial nerves in total. Figure 1 — The location of the cranial nerves on the cerebrum and brainstem. Figure 2 — Superior view of the skull base showing the foramina and which cranial nerves pass through them. They are the only cranial nerves to pass through canals.
The nervous system is the master controlling and communicating system of the body. Every thought, action, and emotion reflects its activity. Its signaling device, or means of communicating with body cells, is electrical impulses, which are rapid and specific and cause almost immediate responses. The nervous system does not work alone to regulate and maintain body homeostasis ; the endocrine system is a second important regulating system. We only have one nervous system, but, because of its complexity, it is difficult to consider all of its parts at the same time; so, to simplify its study, we divide it in terms of its structures structural classification or in terms of its activities functional classification.
Compact bone , also called cortical bone , dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces lacunae that contain the osteocytes , or bone cells. Compact bone makes up 80 percent of the human skeleton ; the remainder is cancellous bone , which has a spongelike appearance with numerous large spaces and is found in the marrow space medullary cavity of a bone. Both types are found in most bones. Compact bone forms a shell around cancellous bone and is the primary component of the long bones of the arm and leg and other bones, where its greater strength and rigidity are needed. Mature compact bone is lamellar, or layered, in structure. It is permeated by an elaborate system of interconnecting vascular canals, the haversian systems, which contain the blood supply for the osteocytes; the bone is arranged in concentric layers around those canals, forming structural units called osteons.

Attribution CC BY. The units listed in this text were very informative. They covered all content at for the level of text. Felt the descriptions and content was more than enough for the level of education for a course with this text.
Knowing and understanding the main anatomy and organ functions of each human body system will set you on track towards scoring higher on the HESI without studying harder or spending hours poring over every detail of your massive textbook. As you come closer to completing your prerequisites, it is now time to begin preparations to take the HESI A2 Entrance Exam in order to apply and get into the nursing school of your choice. This is why the HESI is used by other healthcare programs and not just nursing schools.
