The excretory system eliminates waste from the body through the urinary system and sweat glands. The urinary system produces about 1.4 liters of urine per day by filtering waste from the blood in the kidneys and removing it from the body via the ureters, bladder, and urethra. Sweat glands also help remove waste by secreting sweat through the pores in the skin to cool the body down during physical activity or hot conditions.

The excretory system
The excretory system eliminates waste from the body through the urinary system and sweat glands. The urinary system filters waste from the blood and produces urine, which travels from the kidneys to the bladder and is then excreted. Sweat glands also help remove waste when activated during physical activity or high temperatures, secreting sweat through pores in the skin. Maintaining healthy excretory and respiratory systems requires removing waste, staying hydrated, and cooling off through sweating or other methods.
Unrinary system
The urinary system filters wastes from the blood and excretes it as urine. It includes the kidneys, which filter toxins and regulate fluid balance, removing wastes from the blood to produce urine. The ureters carry urine from the kidneys to the urinary bladder, an elastic sac that stores urine until it is excreted through the urethra. The urinary system works hard to clear poisons from the blood and maintain the body's water balance by producing and excreting urine.

It has four main organs that remove waste from the body: the lungs, which exhale carbon dioxide; the skin, which sweats out salts and urea; the liver, which produces bile and converts nitrogenous wastes to urea; and the kidneys, which are the major organ of excretion that filter wastes like urea and salts from the blood into urine. The kidneys contain nephrons that filter the blood, reabsorb useful substances, and secrete other substances into urine, which is then excreted through the ureters, bladder, and urethra. Excretion is essential to remove cellular waste and maintain homeostasis.
Power point presentation
The document discusses the key features of the human excretory system. The excretory system includes the kidneys, which filter waste from the bloodstream. Useful substances are reabsorbed into the blood while waste dissolved in water becomes urine. The urine travels from the kidneys to the bladder through ureters, where it is stored until passing through the urethra. Sweat also helps remove water and salt through the skin, especially on hot days.
Excretory system
The excretory system removes waste from the body through various organs including the lungs, skin, colon and kidneys. The kidneys filter blood and produce urine by selectively reabsorbing useful substances and excreting waste like urea and salts. Urine travels from the kidneys through the ureters to the bladder for storage and then exits through the urethra. The main functions of the excretory system are to eliminate cellular waste and maintain chemical balance in the body. Diseases can occur if the system is not working properly, such as kidney stones, cystitis and renal insufficiency.

Urine and urinalysis
Urine is the body's liquid waste composed of water, salt urea and uric acid. Urine can be evaluated by its physical appearance (color, cloudiness, odor, clarity), also referred to as a macroscopic analysis. It can be also analyzed based on its chemical and molecular properties, including microscopic assessment.
Excretory system in Human (Class 10)
Life of every organism depends on certain basic processes. Excretion is one among them. Different organisms follow different modes of excretion. In complex organisms including humans, there is a specialized system for excretion called human excretory system.
The Human Excretory Organs
List three main excretory organs and provides a brief description of each excretory organ and their waste product.
HUMAN EXCRETORY.pdf
Various waste products are formed in our body as a result of many
metabolic activities taking place inside the body. These waste substances if
accumulated would poison cells or slow down their metabolism. Hence, the body must
get rid of these unwanted substances.The metabolic wastes to be excreted include
CO2, H2O, fat, ammonia, urea and uric acid.
The nourishment coming from food that is simplified or processed by digestion is consumed by the blood and conveyed all through the body. When this absorbed food is broken down in the tissues and many toxic and poisonous substances are produced which should be removed as they may be fatal if present beyond a certain concentration. The removal of these substances is known as excretion. Excretion and osmoregulation, both are interconnected processes and occur side by side. in higher vertebrates like humans, kidneys perform both the functions, excretion as well as osmoregulation.The system responsible for these function is known as the excretory system or urinary system

La guerra civil española
La guerra civil española estalló en 1936 cuando algunos generales se sublevaron contra la Segunda República, dividiendo a España.

The digestive _system_marina_y_susana
The digestive system extracts nutrients from food and expels undigested waste. It begins with saliva production in the mouth triggered by smell to help crush food with teeth. Food is then sent as a bolus down the esophagus to the stomach, where strong muscles and gastric juices break it down into a liquid that passes into the small intestine for further digestion and nutrient absorption. Undigested waste then moves to the large intestine and leaves the body through the anus.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

- 2. THE EXCRETORY SYSTEM The excretory system eliminates (or excretes) waste products from our body. Our body excretes carbon dioxide,urine and water. The excretory system consists of the urinary system and the sweat glands.
- 3. THE URINARY SYSTEM The urinary system is de principle way in which the body gets rid of waste from blood.It produces about 1.4 litres of urine every day. 1. The renal arteries carry blood to the kidneys. 2. The kidneys eliminate water and waste products from the bood.This combination of water and harmful subtances forms urine. 3. Urine leaves the kidneys and passes down through two tubes called the ureters to the bladder. 4. When the bladder is about half –full, it sends signals to the brain that it needs to be emptied.This is when you want to go to the toilet! 5. The bladder is empied by onether tube called the urethra.
- 4. SWEATING Our body also eliminates waste products through the skin.When we get hot, sweat glands in our skin are activate to cool down the body. These glands excrete sweat which is a mixture of water and minerals. Sweat leaves our body through the pores.
