The circulatory system involves blood being pumped from the heart through blood vessels to supply oxygen and food to the body. The heart is made up of two pumps - the right pump sends blood to the lungs to remove carbon dioxide and absorb oxygen, while the left pump sends the oxygenated blood to the rest of the body. This ensures the body's needs for oxygen and nutrients are met through the circulatory system's transportation of blood.

Cirulatory system
The document discusses the human circulatory system. It explains that the circulatory system involves blood being pumped from the heart and circulated throughout the body. The heart is a muscular organ made up of two pumps - the right pump sends blood to the lungs to absorb oxygen, while the left pump sends oxygenated blood to the rest of the body. The circulatory system transports oxygen and nutrients to tissues and removes carbon dioxide, enabling the rapid supply of materials needed throughout the body.
The human circulatory system
The human circulatory system consists of three main parts: the heart, lungs, and blood vessels. The heart pumps oxygenated blood to the lungs, where carbon dioxide is removed and oxygen is added. The blood is then pumped throughout the body via arteries, veins, and capillaries, supplying oxygen and nutrients to cells and removing waste before returning to the heart to restart the cycle.

There are two main types of circulatory systems - open and closed. In an open system, blood is only partially contained as it travels through sinuses and vessels to directly contact tissues before returning to the heart. In a closed system, blood is entirely contained within vessels that extend throughout the body. Most vertebrates have a closed system. Circulatory patterns also differ - single-loop systems have one pump moving blood unidirectionally while double-loop systems have two pumps moving blood to and from the lungs or gills in two separate loops. Modern mammals have evolved four-chambered hearts that act as two separate pumps to separately oxygenate blood.
Circulation 1-1B
The document discusses how the circulatory and respiratory systems work together to provide cells with nutrients and oxygen while removing carbon dioxide waste. The circulatory system transports blood throughout the body in vessels like arteries, veins, and capillaries. As blood flows through the lungs, it picks up oxygen and releases carbon dioxide. This oxygen-rich blood is then pumped by the heart to cells throughout the body via capillaries, where oxygen is delivered and carbon dioxide is picked up before the blood returns to the heart again. In this way, the circulatory and respiratory systems continuously exchange gases and transport nutrients to keep cells alive.

Introduction
The circulatory system consists of the heart, blood, arteries, veins, capillaries, and lymphatic system. The heart pumps blood through the arteries, which branch into smaller arterioles and capillaries where nutrients and oxygen are delivered and waste is removed. The veins and venules then return deoxygenated blood back to the heart. The lymphatic system works with the circulatory system to collect and return fluid that leaks from capillaries back to the bloodstream. Blood is the main transport medium and carries oxygen, carbon dioxide, nutrients, waste, water, white blood cells, platelets, hormones, heat, and buffers throughout the body to maintain homeostasis.

Ch 32 & 33 lecture
Circulatory systems transport nutrients, oxygen, waste and more throughout an animal's body. There are two main types - open systems where blood flows freely through tissues, and closed systems where blood remains confined to vessels. The vertebrate heart has chambers and valves that work in a coordinated cycle to pump blood. Contractions are regulated by electrical signals from a pacemaker, moving blood to the lungs and throughout the body in separate oxygenated and deoxygenated loops.
Cardiovascular System
The cardiovascular system has three main functions:
1. It transports oxygen, nutrients, water, and removes carbon dioxide through the blood.
2. It regulates body temperature as blood absorbs and transports heat to the lungs and skin.
3. It provides protection as antibodies in the blood fight infection and blood clots to seal wounds.
Parts of the heart and their functions
This document describes the main parts of the heart and their functions. It discusses how the superior vena cava and inferior vena cava deliver deoxygenated blood to the right atrium. It then explains that the right ventricle pumps deoxygenated blood to the lungs via the pulmonary artery and the left ventricle pumps oxygenated blood from the lungs to the body through the aorta. The document also mentions the roles of the valves in regulating blood flow through the heart chambers.
Ks4 the heart and circulatory system
The circulatory system uses the heart to pump blood throughout the body via blood vessels. The heart has four chambers - two upper atria and two lower ventricles - which work together to circulate blood in two loops. Valves between the chambers prevent backflow of blood. During each heartbeat, the atria contract together then the ventricles contract to pump blood out of the heart.
The Heart
The heart is located in the chest cavity and is about the size of a fist. It has four chambers - two upper atria and two lower ventricles. The heart is enclosed in a double-walled sac called the pericardium. Blood enters the heart through the vena cava and pulmonary veins into the atria, and is then pumped out of the ventricles through the aorta and pulmonary artery. The left side pumps blood through the systemic circulation while the right side pumps to the pulmonary circulation.

Human Heart
The heart is a pumping organ located in the chest that continuously circulates blood through the body. It has four chambers - the two upper chambers are the atria and the two lower chambers are the ventricles. The septum separates the chambers and prevents mixing of oxygenated and deoxygenated blood. Blood flows from the right atrium to the right ventricle then to the lungs, returns oxygenated to the left atrium and left ventricle, then is pumped through the aorta to the rest of the body in a continuous cycle.

The heart pumps blood through the arteries and veins, which carry oxygen, nutrients, hormones, carbon dioxide, and other wastes. Capillaries allow for exchange of materials between blood and tissues. Blood transport is facilitated by blood cells like platelets and the fluid lymph. The heart has four chambers to keep oxygenated and deoxygenated blood separate as it circulates through the body and lungs.
The Study of Human Heart (PDF version)
The human heart is about the size of a clenched fist and is located in the chest. It is made of cardiac muscle and is divided into four chambers - two upper atria and two lower ventricles. The heart pumps blood through two circuits: the pulmonary circuit oxygenates blood in the lungs, while the systemic circuit pumps oxygenated blood to the entire body. It contracts over 70 times per minute due to electrical impulses generated by the sinoatrial node that spread through the heart and cause the chambers to contract in the correct sequence, pumping blood out of the heart.
Rutherford’s atomic model
Rutherford designed an experiment in 1911 where he bombarded a thin gold foil with alpha particles. He observed that most particles passed through, some were deflected at small angles, and a few were scattered at large angles or bounced back. From this, Rutherford concluded that atoms have a tiny, massive positive nucleus surrounded by electrons in orbits. This overturned Thomson's "plum pudding" model of the atom. Rutherford's results could not be explained by Maxwell's electrodynamics and he could not explain how electrons remained stable in their orbits without losing energy and spiraling into the nucleus.

RUTHERFORD ATOM MODEL
Rutherford conducted an experiment where he fired alpha particles at a thin gold foil. Most alpha particles passed straight through the foil, but some were deflected at small angles and a few were deflected at large angles. This showed that the positive charge and mass of an atom must be concentrated in a small nucleus at the center, with electrons orbiting the outside. The Rutherford model concluded that (1) the positive charge of an atom is contained in a nucleus at its center, (2) there is mostly empty space between the nucleus and electrons, and (3) electrons revolve around the positively charged nucleus.
Ernest Rutheford PowerPoint
Ernest Rutherford (1871-1937) was a pioneering physicist and chemist from New Zealand who made seminal discoveries about nuclear physics and radioactive decay, including identifying three types of radiation (alpha, beta, gamma rays) and determining that the atom has a small, dense nucleus, work for which he received the 1908 Nobel Prize in Chemistry. Rutherford made many other contributions including the first artificial nuclear reaction and speculation about the existence of neutrons, and he is honored on stamps and currency in New Zealand and elsewhere for his revolutionary scientific achievements.

Radiation
This document provides an overview of radiation and its effects on the human body. It defines radiation as the process of emitting energy through waves or particles, and identifies ionizing radiation as radiation that can knock electrons out of atoms. The types of ionizing radiation are identified as alpha particles, beta particles, gamma rays, x-rays, and neutrons. Sources of radiation include naturally occurring materials, medical equipment, consumer products, and industrial uses. Exposure to radiation can damage cells and DNA, potentially leading to cell death or cancer development over time. Methods to control radiation exposure include minimizing time spent near sources, maximizing distance, and using shielding to block radiation.
RUTHERFORD ‘ S MODEL OF AN ATOM
Ernst Rutherford was a physicist who won the Nobel Prize in 1908 for his work discovering the nuclear model of the atom. He conducted experiments where he bombarded gold foil with alpha particles, finding that a small fraction were deflected at 180 degrees, indicating the positive charge of an atom is concentrated in a tiny nucleus. He concluded atoms have a small, dense positively charged nucleus surrounded by electrons. This led to replacing the plum pudding model with the Rutherford model of the atom and eventually the Bohr model. However, the Rutherford model could not explain the stability of atoms as it predicted electrons would radiate energy and collapse into the nucleus.
Types of radiation
Different forms of radiation, including alpha, beta, and gamma, are emitted during radioactive decay as the unstable nucleus transforms into a more stable form. Alpha particles are helium nuclei, beta particles are electrons, and gamma radiation is electromagnetic radiation similar to x-rays. Ernest Rutherford discovered alpha particles in 1899 while studying uranium. The inverse square law states that the intensity of radiation decreases inversely with the square of the distance from the source. This law can be used to calculate intensity at different distances from a radioactive source.
Basics Of Radiation
The document discusses different types of radiation including ionizing radiation like alpha, beta, and gamma rays. It describes their properties and how they are emitted from radioactive atoms. It also covers radiation units, health effects of radiation exposure, and common sources of radiation including medical uses, consumer products, space exploration, and nuclear power. Radiation is used for a variety of applications but also poses health risks if exposure limits are exceeded.

Marasmus results from general malnutrition and lack of energy and protein, causing a lean body and sunken eyes. Rickets is caused by lack of vitamin D and calcium in children, resulting in soft bones and bent limbs. The document emphasizes the importance of a balanced diet containing all essential nutrients to prevent these deficiency diseases.
Separation Techniques
A pure substance consists of only one substance, while a mixture contains two or more substances not chemically combined. The purity of a substance can be determined by testing its fixed melting and boiling points or using chromatography. Various separation methods exist that separate substances based on differences in their physical properties such as solubility, boiling points, magnetism, and ability to sublime. Common separation methods include filtration, crystallization, distillation, chromatography, and magnetic attraction.

Circulatory system
The circulatory system transports oxygen, nutrients, and waste throughout the body. The heart pumps blood through blood vessels in a continuous cycle, sending oxygenated blood from the lungs throughout the body and collecting deoxygenated blood to pump to the lungs. The lungs oxygenate the blood and remove carbon dioxide, while the lymphatic system transports lymph fluid and plays an important role in immunity.

Sheep Heart CirculatoryRespiratory Dissection Lab Sheep .pdf
Sheep Heart:
Circulatory/Respiratory Dissection Lab - Sheep Heart Circulatory and Respiratory systems are
critical adaptations that allow animals to 1) take in oxygen from the external environment to make
energy in cell respiration, 2) to get rid of carbon dioxide waste produced in cell respiration, and 3)
cycle nutrients throughout the body for use by the cells. The respiratory system allows animals to
do gas exchange, moving oxygen from the external environment into the blood and CO2 from the
blood into the external environment. The circulatory system pumps the blood throughout the body
to move oxygen, CO2, and nutrients to their final destinations. There are two types of circulatory
systems in animals: closed and open. Both types have at least one pump (i.e. heart) to push the
circulatory fluid throughout the body. In closed systems, the blood is ALWAYS contained within
blood vessels, while in open systems, the fluid -- called Ifinph -- is pumped into open sinuses
instead of blood vessels. Humans have a CLOSED circulatory system, so we will focus on that
model today. Sheep Sheep are vertebrate chordate mammals like humans, so their circulatory
anatomy is almost identical to ours. They have a 4-chambered heart and blood vessels that
contain blood.Heart Diagram - External The sheep heart has 4 chambers -- a left and right atrium
on top (the external surface of the atria is called an auricle), and a left and right ventricle on
bottom. Note that whenever we refer to anatomical positions, we refer to left and right from the
position of the organism we're looking at. So the "right" is on our left, and vice versa. You can see
the pulmonary trunk/artery in blue on top of the heart, and the aorta in red. These two arteries
carry blood away from the heart after it has been pumped out of the ventricles. The pulmonary
veins and vena cava return blood to the atria. The cells of the heart are fed oxygen via blood in the
coronary arteries, which are visible on the surface of the heart. Blockage of these arteries starves
the heart of oxygen, resulting in a heart attack.The basic layout of the mammalian heart. Find the
four chambers of the heart: the left and right atria on top, and the left and right ventricles on
bottom. Remember that the heart's purpose is to pump blood throughout the body. Which
chambers of the heart beat first? Notice the valves separating them. Which valve is on the right
side of the heart? The left? What is the purpose of these valves? Do you see any other valves in
the heart?.
The Circulatory System Essay
The circulatory system transports blood throughout the body via arteries, capillaries and veins. The heart has four chambers - two atria and two ventricles - with the right side pumping deoxygenated blood to the lungs and left side pumping oxygenated blood to the body. Blood circulates through a closed loop, completing its circuit approximately every 30 seconds as it delivers oxygen and nutrients to tissues and removes waste.
The Circulatory System
The circulatory system consists of the heart, blood, and blood vessels. The heart pumps oxygenated blood received from the lungs through arteries throughout the body and returns deoxygenated blood back to the right side of the heart through veins in a closed loop. Blood is transported through increasingly smaller blood vessels from arteries to arterioles to capillaries where gas and nutrient exchange occurs through diffusion across the capillary walls before returning to the heart.
Heart and Blood Circulation in the Human Systemppt
The circulatory system consists of the heart, which pumps blood through arteries and veins to transport oxygen, nutrients, and waste throughout the body. The heart has four chambers - two upper chambers called atria and two lower chambers called ventricles. The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it out to the body.
Circulatory system
1) The circulatory system, also called the cardiovascular system, consists of the heart, blood vessels, and blood, and circulates blood throughout the body.
2) The heart pumps blood through two circuits - the pulmonary circulation to the lungs and systemic circulation to the rest of the body.
3) There are three types of blood vessels - arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart while veins carry deoxygenated blood back to the heart. Capillaries allow for the exchange of water, waste and nutrients between blood and body tissues.
Circulatory system pdf
The human circulatory system consists of three main parts - the heart, lungs, and blood vessels. The heart pumps oxygenated blood to the lungs, where carbon dioxide is removed and oxygen is added. The blood is then pumped throughout the body via arteries, veins, and capillaries to supply oxygen and nutrients to cells and remove waste before returning to the heart to restart the cycle.
Core 3 Part 2
The cardiovascular system circulates blood throughout the body, delivering oxygen and nutrients to tissues and removing carbon dioxide and waste. It includes the heart, blood vessels, and blood. The heart pumps blood in a continuous circuit, first to the lungs to receive oxygen and then throughout the body to deliver oxygen and remove carbon dioxide. Blood is made up of plasma and cellular components like red blood cells, which carry oxygen, and white blood cells, which provide immune functions. Platelets in the blood cause clotting to prevent blood loss from injuries. The heart has four chambers and uses electrical signals and valves to efficiently pump blood in two separate circuits to the lungs and body.
LIFE PROCESSES PART- 5.pptx
The document summarizes the transportation system in human beings. It describes how blood transports oxygen, nutrients, waste and other materials throughout the body using a network of blood vessels and the heart as the pumping organ. Blood is circulated via double circulation, where it passes through the heart twice - first to pick up oxygen in the lungs and then distribute it to tissues before returning to be reoxygenated. The system is maintained by platelets that help form clots to plug leaks in blood vessels. Lymph and tissue fluid also transport nutrients and remove excess fluid from tissues before returning to blood circulation.
The Human Body
The heart is a muscle that pumps blood throughout the body, providing oxygen and nutrients and removing waste. It has four chambers and works as a pump, with the right side pumping blood to the lungs and left side to the rest of the body. The heart's rhythm is controlled by electrical impulses and it requires coronary arteries on the outside to supply its own muscle with oxygenated blood. High blood pressure can damage the heart over time if not managed.
Class 7 Chapter 13 Transportation
1. The circulatory system transports nutrients, oxygen, hormones, and removes wastes through the blood vessels, heart, and blood.
2. The heart pumps blood through arteries which branch into smaller vessels and capillaries where nutrients and gases are exchanged, then blood returns via veins to the heart.
3. Blood is composed of plasma and blood cells including red blood cells which carry oxygen, white blood cells which fight infection, and platelets which help clotting.
Circulatory System Essay
The circulatory system transports blood throughout the body via arteries, veins, and capillaries. The heart pumps deoxygenated blood to the lungs and oxygenated blood to the rest of the body in separate circuits. Red blood cells carry oxygen and nutrients to tissues while white blood cells help fight infection. Together, blood flow and gas exchange allow all cells to receive necessary materials and remove waste.
The human heart
The human heart is a muscular pump about the size of a fist that beats around 100,000 times per day, pumping blood to all parts of the body. It has four chambers - two upper atria that receive blood and two lower ventricles that pump blood out, with valves allowing blood to flow in only one direction. Deoxygenated blood returns to the right side of the heart then is pumped to the lungs where it receives oxygen before returning to the left side and being pumped via arteries throughout the body on its cycle.
The human heart
The heart is a muscle that acts as two pumps to circulate blood through the body. It has four chambers - two upper atria that receive blood and two lower ventricles that pump blood out. The heart beats over 100,000 times per day, circulating blood through a network of arteries and veins to deliver oxygen and nutrients to cells and remove waste. Regular exercise and a healthy diet help keep the heart muscle strong.

Lab Practical Study Guide
Here are the most common forms of abdominal trauma:
1. Blunt trauma - This is caused by blunt, non-penetrating forces applied to the abdomen, such as a kick, punch, fall, or car accident. Blunt trauma can cause bruising, bleeding, and organ damage or rupture without breaking the skin. The liver, spleen, and kidneys are most commonly injured in blunt trauma.
2. Penetrating trauma - Sharp objects like knives, bullets, or fragments can penetrate the abdominal wall and damage internal organs. Gunshot wounds and stab wounds are examples of penetrating trauma.
3. Blast injuries - Explosions can cause penetrating or blunt force trauma to the abdomen from bomb fragments or the blast wave itself
Cardio system
The cardiovascular system consists of the heart and blood vessels. The heart is a muscular organ located in the chest that pumps blood through the body in a process called circulation. It has four chambers - two atria that receive blood and two ventricles that pump blood. The heart functions throughout life to circulate oxygenated blood from the lungs and nutrients throughout the body via two types of circulation - pulmonary and systemic. The cardiac cycle describes the repeating sequence of heart contraction and relaxation that pumps blood through the circulatory system.

The classification system helps scientists identify and categorize different types of organisms.
Electricity in action
Electricity is produced through various sources and used in many aspects of daily life. Some key points:
- Electricity is produced from sources like hydroelectric power through dams, thermal power by burning fossil fuels, and renewable sources like solar and wind.
- Pakistan's major hydroelectric dams are at Tarbela, Mangla, and Warsak. Thermal power stations are located in various cities like Hyderabad and Jamshoro.
- Electricity can be produced through movement like turning a magnet within a copper coil or wind power, and through non-renewable sources like burning fossil fuels in thermal power plants.
- Electricity is transmitted as alternating current but many devices run on direct
Sound class six
Sound is produced by vibrations that travel in waves through a medium such as air, water or solid materials. Different musical instruments produce sound using different methods of vibration like vibrating vocal chords, air, strings or membranes. The characteristics of sound include intensity, pitch and tone which vary based on amplitude, frequency and quality of vibration. Sound travels faster in solids than liquids or gases and requires a medium to travel through. When sound waves hit a surface, they can bounce back through a process called echo.
