The Excretory system is responsible for the elimination of wastes produced by homeostasis.
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. ... From there, urine is expelled through the urethra and out of the body.
The circulatory system transports fluids throughout the body;
it consists of the cardiovascular and lymphatic systems.
The heart and blood vessels make up the blood transportation network, the cardiovascular system.
Through this system, the heart pumps blood through the body’s vast system of blood vessels.
The blood carries nutrients, oxygen, and waste products to and from the cells.
VASCULAR CIRCUITS
The heart consists of two muscular pumps dividing the circulation into two components:
pulmonary circulations
systemic circulations or circuit
Pulmonary Circulation
Rt ventricle propels low O2 blood into the lungs via the pulmonary arteries.
CO2 is exchanged for O2 in the capillaries of the lungs.
Then the O2 -rich blood is returned via the pulmonary veins to the Lft atrium.
This circuit, from the right ventricle through the lungs to the left atrium, is the pulmonary circulation.
Systemic Circulation
Left ventricle propels the O2 -rich blood through systemic arteries (the aorta and its branches),
exchanging O2 and nutrients for CO2 in the remainder of the body’s capillaries.
Low- O2 blood returns to right atrium via systemic veins (tributaries of the superior and inferior vena cava).
This circuit, from left ventricle to right atrium, is the systemic circulation.

Explore the mysteries of our skeletal system and delve into the fascinating stories behind our bones. Uncover the unique characteristics of our skeletons and understand how they protect our bodies and provide us with mobility.
The framework of bones and cartilage which gives shape and support to the body an animal is called skeleton. Skeletal structure is composed of hard material which is made up of calcium called bones. The human skeleton is made up of 206 bones. In human beings, the skeleton is present in side the body, so it is called endoskeleton.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

18. The
Appendicular
skeleton
• It consists of the bones of the shoulders,
