Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination

Function The urinary system helps maintain homeostasis by regulating water balance and by removing harmful substances from the blood. The blood is filtered by two kidneys‚ which produce urine‚ a fluid containing toxic substances and waste products. From each kidney‚ the urine flows through a tube‚ the ureter‚ to the urinary bladder‚ where it is stored until it is expelled from the body through another tube‚ the urethra. The kidneys are surrounded by three layers of tissue: The renal fascia

1. Anatomy- study of the structure and shape of the body and its parts. Physiology- study of how the body and its parts work or function. The relationship between anatomy and physiology is that anatomy has to do with the structures and names of the body‚ while physiology has to do with the function and how the structure works. An example of their correspondence is the cardiovascular system‚ consisting of the heart and blood vessels (anatomy) and how the heart pumps oxygen‚ nutrients‚ and wastes

This lab connects to the biology course through the unit of homeostasis‚ specifically the lesson on sensations. Sensation is the conscious awareness of the stimulus. Additionally‚ a reception receives the stimulus. For the visual response of the lab‚ the photoreceptors (contain light-absorbing visual pigments) are the cones since the subject is present in light (colour). The cones detect and then covert the stimulus into an action potential. The eye obtains the physical stimulus in the form of light

their own job while working together to keep the body healthy. The kidneys “prevent the buildup of wastes and extra fluid in the body‚ keep levels of electrolytes stable‚ such as sodium‚ potassium‚ and phosphate‚ make hormones that help regulate blood pressure‚ make red blood cells‚ and keep bones strong (“Your Kidneys and How They Work” 3).” The ureters are thin muscular tubes that are 8-10 inches long that carry urine from the kidney to the bladder. The two layers of smooth muscle that

Magnesium is required for energy production‚ oxidative phosphorylation‚ and glycolysis. It contributes to the structural development of bone and is required for tToo much magnesium from food does not pose a health risk in healthy individuals because the kidneys eliminate excess amounts in the urine [28]. However‚ high doses of magnesium from dietary supplements or medications often result in diarrhea that can be accompanied by nausea and abdominal cramping [1]. Forms of magnesium most commonly reported to

Introduction: Homeostasis is the tendency of the body to seek and maintain equilibrium‚ a state of balance‚ within its internal environment. Endotherms are “warm blooded” animals that produce and maintain their own internal body heat. Most mammals and a few birds‚ are endotherms; this is beneficial because the enzymes in the body that carry out metabolic processes have an optimum temperature at which they function‚ having the body constantly be‚ or be close to‚ this optimum internal temperature
