The urinary system removes waste from the blood through the kidneys, ureters, bladder, and urethra. The kidneys filter the blood and remove waste, which travels through the ureters and is stored in the bladder. When full, the bladder empties waste out through the urethra. Failure to treat a bladder infection can lead to a kidney infection as bacteria can travel back up the urinary system.

Unit b section - 3.4 excretory system
The excretory system removes waste from the body through organs like the lungs, skin, kidneys, and liver. The kidneys act as filters for the blood, removing waste products like urea, salts, and water to produce urine. The liver converts toxic ammonia into less harmful urea, which is then filtered out by the kidneys. Urine is stored in the bladder and exits the body through the urethra. The excretory system is vital for removing different types of waste and keeping the body's chemical levels balanced.

Most of these cases are diagnosed on antenatal scan or when they present with urinary tract infections. It is a congenital condition and may require various procedures to salvage the renal functions.
excretion and kidneys.ppt
The kidneys remove waste from the body through the process of excretion. They filter the blood, removing urea and excess water to produce urine. The two kidneys each contain nephrons, which act as filters. Blood enters the nephron and is filtered. Useful substances like glucose and salts are reabsorbed while urea and water remain and become urine. Urine travels from the nephrons to the bladder via the ureters for storage and later excretion. Kidney failure can occur from conditions like diabetes and high blood pressure. It is treated through dialysis or kidney transplantation.

Unit – 8:
Structure and functions of the kidney, ureters, urinary bladder and urethra
Formation and composition of urine.
Fluid and electrolyte balance
Structure and functions of the skin.
Regulation of the body temperature.
Excretory system:
The excretory system is performs the function of excretion
It is the process of removing the wastes
There are several parts of the body that are involved in this process such as sweat glands, the liver, the lungs and the kidney system
Kidney:
The kidneys are a bean-shaped organs - found abdominal cavity, just below the rib cage.
The right kidney is slightly lower than the left because of the position of the liver.
Every human has two kidneys.
Diagram of Renal System
Structure of kidney:
Kidney consist of 3 basic parts
Renal cortex (outer layer )
Renal medulla (inner layer )
Renal pelvis.
Renal cortex:
The renal cortex is the outer layer of the kidney, it is covered with capsule
Erythropoietin a hormone is produced in the renal cortex (Erythropoiesis)
Renal medulla:
Renal medulla is the inner layer of the kidney. The medulla consists of multiple pyramidal tissue masses, called the renal pyramids, which are triangle structures that contain a network of nephrons
Renal pelvis:
The renal pelvis contains the hilum.
The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney
It is also the point of exit for the ureters carry urine away from the kidney
Both of the ureters supply the urine into urinary bladder,
From there, urine is expelled through the urethra and out of the body.
The blood arrives at the kidney via the renal artery, renal veins collect deoxygenated blood
Nephron:
The nephron is the structural and functional unit of the kidney.
It is composed of renal corpuscle and a renal tubule.
Parts of Nephron:
Renal corpuscle (glomerulus within bowman's capsule)
Proximal convoluted tubule
Intermediate tubule (loop of Henle)
Distal convoluted tubule
Collecting ducts
1. The Glomerulus:
The glomerulus is receives blood supply from an afferent arteriole of the renal circulation.
Here, fluid and solutes are filtered out of the blood and into the space made by Bowman’s capsule.
A group of specialized cells known as juxtaglomerular apparatus (JGA) are located around the afferent arteriole where it enters the renal corpuscle. The JGA secretes an enzyme called renin, it is involved in the process of blood volume homeostasis (Bp).
2. Proximal Convoluted Tubule:

Refraction of light by salah sari
This document defines refraction of light and compares it to reflection. It explains that refraction occurs when light changes speed and direction moving between transparent media, while reflection is when light bounces off a surface. The document labels a refraction diagram and defines terms like incident angle, refracted angle, and angle of deviation. It also defines the index of refraction and provides examples of how light behaves when passing between media of different densities, including cases where the light ray is perpendicular to the surface, passes to a more dense medium, or passes to a less dense medium, potentially undergoing total internal reflection.
Forces by salah sari and doaa mahdawi
This document defines and describes the conditions of equilibrium for a body. It defines a force, discusses different types of forces including contact forces and forces acting at a distance. It then defines equilibrium as when two forces acting on a body have the same line of action, opposite directions, and equal magnitudes. An example problem is also included to demonstrate identifying forces and evaluating equilibrium conditions for a specific body.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
