The circulatory system comprises of the heart, blood vessels, and blood. The heart pumps blood through arteries into the body and receives it back through veins. There are three types of blood vessels: arteries, veins, and capillaries. Blood contains red blood cells, white blood cells, and plasma, which is 90% water and carries substances like carbon dioxide, amino acids, glucose, antibodies, hormones, and urea throughout the body to supply oxygen and nutrients to organs and tissues.

Body fluids and circulation 2
This document provides an overview of the human circulatory system, including:
1. It describes the structure of the human heart, including the pericardium, septum, atrioventricular valves, chordae tendinae, and papillary muscles.
2. It explains the conducting system of the heart, including the sinoatrial node, atrioventricular node, Purkinje fibers, and bundle of His.
3. It outlines the cardiac cycle and its steps, including atrial systole, ventricular systole, atrial diastole, and complete cardiac diastole, as well as the opening and closing of valves.
Circulatory assignment
The document discusses the circulatory systems of different vertebrates including fish, reptiles, and humans. It notes that while all vertebrate hearts have a closed circulatory system, chambered structure, and valves, they differ in their number of chambers and whether they have septum. Fish have two chambers with mixing of deoxygenated and oxygenated blood while reptiles and humans have four chambers with no mixing in humans. The functions of blood cells are also summarized, including their roles in oxygen transport, nutrient transport, phagocytosis, immune defense, and blood clotting.
Circulation of body fluids
Circulation of body fluids involves the movement of fluids through the circulatory system, including blood and lymph. The circulatory system consists of the blood vascular and lymphatic systems. The blood vascular system contains blood, blood vessels, and the heart. Blood is a liquid that circulates throughout the body, consisting of plasma and corpuscles like red blood cells, white blood cells, and platelets. Blood vessels include arteries that carry blood away from the heart and veins that carry blood back to the heart. The heart is a four-chambered pump that drives double circulation of oxygenated and deoxygenated blood through two separate circuits.
Blood cells & Cardiovascular system
This document discusses blood cells, the cardiovascular system, and different types of hearts. It explains that blood is composed of erythrocytes, leukocytes, and platelets that transport oxygen, nutrients, waste products, and help maintain homeostasis. The cardiovascular system circulates blood throughout the body to supply tissues with oxygen and nutrients while removing carbon dioxide and waste. Fish have a two-chambered heart with single circulation, while reptiles have a three-chambered heart and some blood mixing. Humans have a four-chambered heart that fully separates oxygenated and deoxygenated blood with double circulation.
Body fluids and circulation
This document provides an overview of body fluids and circulation. It discusses the components of blood, including plasma, red blood cells, white blood cells and platelets. It describes the circulatory system in humans, including the structure and functioning of the heart. The document outlines the cardiac cycle and explains electrocardiography. It also briefly mentions common circulatory disorders.
9 syllabus statements
This document outlines the key concepts around transport in animals from the Cambridge IGCSE Chemistry syllabus. It discusses the circulatory system, describing single and double circulation. It also covers the structure and functioning of the heart, describing the layers of the heart wall and how it pumps blood through the body. Finally, it summarizes the components and functions of blood, including red blood cells, white blood cells, platelets and plasma. It also briefly discusses the lymphatic system and blood clotting.
Body fluids and circulation 1
This document summarizes key aspects of blood, lymph, and blood grouping. It discusses how blood consists of plasma and formed elements like red blood cells, white blood cells, and platelets. It describes the functions of these blood components and how red blood cells transport oxygen via hemoglobin. The document also outlines the properties of lymph and its roles in tissue fluid, immune responses, and fat absorption. Finally, it explains blood grouping by ABO and Rh systems, including antigens, antibodies, universal donors and acceptors, and the concept of Rh incompatibility in pregnancy.
Red blood cell
Red is a red blood cell that has matured and is ready to begin its journey through the body. It was created in the bone marrow and its job is to carry oxygen from the lungs to the rest of the body. It travels to the heart where it enters the right side to be oxygenated before traveling to the left side and being pumped throughout the body. Red blood cells circulate for about 30-45 seconds, have a lifespan of around 120 days, then are removed by the spleen. They transport oxygen through veins and capillaries using hemoglobin, which gives them their red color.

BODY FLUIDS AND CIRCULATION CLASS 11 - ASWIN KUMAR
Blood is a connective tissue composed of plasma and formed elements. Plasma is 55% of blood and contains water, proteins, minerals, and blood clotting factors. Formed elements include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and lack a nucleus. White blood cells help fight infection. Platelets help with clotting. Blood types depend on antigens on red blood cells. Matching blood types is important for safe transfusions. The coagulation process involves clotting factors that create fibrin clots to stop bleeding. Lymph is tissue fluid collected by the lymphatic system and returned to veins.

The circulatory system is made up of three independent systems - the heart, lungs, and arteries/veins - that work together to circulate blood, nutrients, gases, hormones, and other substances to and from cells. It transports around 2,000 gallons of blood daily through 60,000 miles of blood vessels. The circulatory system is responsible for homeostasis and fighting disease by moving an average of 5-6 quarts of blood plasma, red and white blood cells, and platelets. It also transports lymph to help rid the body of unwanted materials.

Blood cells
This document summarizes the different types of blood cells: red blood cells, white blood cells, and platelets. Red blood cells carry oxygen throughout the body via blood flow. They contain hemoglobin, an iron-containing molecule. White blood cells are involved in the immune system and protect the body against infection and foreign invaders. There are five types of white blood cells. Platelets function in blood coagulation and have a lifespan of 5-9 days. The main metal present in blood is iron, which is contained in red blood cells. A normal human has 5.78-6.21 liters of blood.
Circle Fish
The fish's circulatory system has a two-chambered heart that pumps oxygen-poor blood to the gills to receive oxygen and then to the systemic capillaries to deliver oxygen throughout the body before returning to the heart to repeat the single circuit. In contrast, the human heart has four chambers and a two-circuit circulatory system with pulmonary and systemic circuits to oxygenate blood and deliver it to the entire body.
Circulatory system
The circulatory system, also known as the cardiovascular system, transports blood throughout the body using the heart and blood vessels. The heart pumps blood through arteries and capillaries, which deliver oxygen and nutrients to tissues and remove waste. Blood then returns to the heart through veins. The circulatory system maintains homeostasis by regulating temperature, pH, and the delivery of substances to cells.
Respiration
The respiratory system allows for the exchange of gases between the blood and external air. In humans, the respiratory tract includes the lungs and structures that move air to and from the lungs. The lungs contain bronchioles and alveoli that provide a large surface area for gas exchange between the blood vessels and air. Plants also exchange gases through diffusion via leaves, stems, and roots using structures like stomata and lenticels.
The red heart journey
The red blood cell carries oxygen through the body via the following path:
1. Red blood cells pick up oxygen in the lungs via the pulmonary arteries after being pumped from the heart's right ventricle.
2. They return to the heart and are pumped from the left ventricle into the aorta and travel through decreasingly smaller arteries to capillaries where they release oxygen.
3. Deoxygenated blood travels through veins back to the heart's right atrium and is pumped to the lungs to restart the cycle, passing through the liver and spleen which remove old red blood cells.
circulatory_system
The circulatory system transports blood throughout the body using arteries, veins, and capillaries. The cardiovascular system pumps blood from the heart to the lungs and body, while the pulmonary system handles blood flow between the heart and lungs. Blood carries oxygen, nutrients, hormones, and waste products as it circulates through the body in a continuous loop. Maintaining a healthy circulatory system requires a balanced diet, regular exercise, avoiding tobacco, and managing stress.
BODY BLOOD AND CIRCULATION _BODY FLUID
18.1.2 Formed Elements
Erythrocytes, leucocytes and platelets are collectively called formed
elements (Figure 18.1) and they constitute nearly 45 per cent of the blood.
Erythrocytes or red blood cells (RBC) are the most abundant of all
the cells in blood. A healthy adult man has, on an average, 5 millions to
5.5 millions of RBCs mm–3 of blood. RBCs are formed in the red bone
marrow in the adults. RBCs are devoid of nucleus in most of the mammals
and are biconcave in shape. They have a red coloured, iron containing
complex protein called haemoglobin, hence the colour and name of these
cells. A healthy individual has 12-16 gms of haemoglobin in every
100 ml of blood. These molecules play a significant role in transport of
respiratory gases. RBCs have an average life span of 120 days after which
they are destroyed in the spleen (graveyard of RBCs).
Leucocytes are also known as white blood cells (WBC) as they are
colourless due to the lack of haemoglobin. They are nucleated and are
relatively lesser in number which averages 6000-8000 mm–3 of blood.
Leucocytes are generally short lived. We have two main categories of WBCs
– granulocytes and agranulocytes. Neutrophils, eosinophils and basophils
are different types of granulocytes, while lymphocytes and monocytes
are the agranulocytes. Neutrophils are the most abundant cells (60-65
per cent) of the total WBCs and basophils are the least (0.5-1 per cent)
among them. Neutrophils and monocytes (6-8 per cent) are phagocytic
cells which destroy foreign organisms entering the body. Basophils secrete
histamine, serotonin, heparin, etc., and are involved in inflammatory
reactions. Eosinophils (2-3 per cent) resist infections and are also
Comparative anatomy of heart structure
1. All chordates have a circulatory system with blood and lymph traveling through separate yet interconnected vessels.
2. In vertebrates the blood vascular system is closed, with a contractile heart and continuous vessels. The heart pumps oxygenated blood from the veins into the arteries.
3. Over the course of evolution, the structure of the heart has become more complex and compartmentalized. In early vertebrates like sharks the heart had two chambers, while in advanced mammals it is a four-chambered heart that fully separates pulmonary and systemic circulation.

Biology:Transport in Humans (JYSS)
The human circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through a closed system of arteries, veins, and capillaries. It has four chambers - two atria which collect blood and two ventricles which pump blood. Blood carries oxygen, nutrients, hormones and waste products as it circulates. It contains plasma, red blood cells, white blood cells and platelets. The circulatory system transports these substances between tissues and organs via a network of blood vessels, and returns waste products to the kidneys and lungs.
transport in human being
The human heart has four chambers - two atria and two ventricles - that pump blood throughout the body via arteries and veins with one-way valves. The heart's rhythm is controlled by a natural pacemaker and can increase during exercise or decrease in response to higher blood pressure. Blood carries oxygen, nutrients, hormones and waste products around the body in a liquid called plasma within three main cell types - red blood cells, white blood cells and platelets.
10 transport in humans 2019
The circulatory system transports blood around the body using blood vessels. Blood carries oxygen, nutrients, hormones and waste products as it circulates from the heart through arteries and veins, with an exchange of substances occurring in capillaries. The circulatory system can operate through single or double circulation, with double circulation being more efficient as blood passes through the heart twice. Heart disease is caused by factors like lack of exercise, diet, stress and smoking, and can lead to coronary heart disease if arteries become narrowed or blocked.
The world of blood vessels
Blood plasma is a straw-colored liquid that makes up 55% of blood volume. It contains water, proteins, glucose, clotting factors, and other dissolved substances. Plasma also transports proteins and electrolytes throughout the body while helping to fight infections. Red blood cells transport oxygen throughout the circulatory system via arteries, arterioles, capillaries, and veins. White blood cells help the immune system fight pathogens. Platelets help the blood to clot and stop bleeding. Together, these components and blood vessels work to supply the body with oxygen and nutrients and remove waste.

This document discusses extremity vascular injuries, which can result in limb loss or death if not properly treated. The most common causes are road traffic injuries. Clinical features include signs of active bleeding, ischemia, pain, pallor, and pulse absence. Imaging like duplex scans and angiography can help diagnose the injury. Early surgical repair of damaged blood vessels is needed to restore blood flow. Complications include compartment syndrome, which requires fasciotomy to reduce pressure. Close monitoring is also needed after reperfusion to watch for systemic effects. With proper emergency treatment and surgery, many extremities can be saved from amputation.
Vascular Emergencies
This document discusses vascular emergencies and trauma, including acute limb ischemia caused by embolism or thrombosis, vascular trauma to the head and neck, cervical veins, subclavian artery, and blunt aortic injury. It also covers abdominal vascular trauma and extremity vascular injuries. Key points include the importance of history and physical exam findings in diagnosis, the need for immediate anticoagulation or surgery depending on the situation, and computed tomography playing a role in identifying injuries from blunt trauma.
Vascular trauma
1. The document discusses various types of vascular injuries including sharp, blunt, transection, laceration, and contusion injuries.
2. Signs of vascular injury in the extremities include pain, pallor, pulselessness, perishing cold, paresthesia, paralysis and the "P's". Complications can include bleeding, ischemia, and complications from vascular injury.
3. Evaluation of vascular injuries involves assessment of signs like hard or soft pulses, Doppler, CT angiography, and possible urgent exploration and repair in cases of threatened limbs with paresthesia and paresis.
Vascular trauma
This document summarizes the assessment and treatment of vascular trauma. It discusses the history of vascular surgery, mechanisms of injury, initial assessment and treatment focusing on controlling bleeding and ischemia. Signs of arterial injury are outlined. Surgical management may involve angiography, open exploration, repair, bypass or ligation. Compartment syndrome is a risk and location of injury impacts outcomes. Treatment of venous and carotid trauma is also addressed.
VESSEL ligation
Ligation of blood vessels is commonly performed in oral and maxillofacial surgery to control bleeding. The document discusses the definition and reasons for vessel ligation. It then describes the general ligation procedure and techniques for ligating specific vessels like the external carotid artery, lingual artery, and internal carotid artery. Ligating vessels helps arrest blood flow after amputation or in cases of hemorrhage, aneurysms, or tumors. While ligation reduces risks, it can also potentially damage nearby nerves or tissues if not performed carefully.
Peripheral Vascular Injuries
This document discusses peripheral vascular injuries. Some key points:
- Peripheral injuries account for 80% of vascular trauma cases, with the lower extremities most commonly involved.
- Combined arterial and skeletal injuries in the extremities significantly increase the risk of limb loss compared to isolated injuries.

Circulatory system
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps oxygen-rich blood received from the lungs through the arteries to the body's tissues, and deoxygenated blood returns to the heart via veins to be re-oxygenated in the lungs. The circulatory system transports nutrients, gases, hormones, and waste products throughout the body and helps fight infections through white blood cells.
Circulatory System BY: EMYLIE LANTORIA.pptx
The document discusses the circulatory systems of various organisms. It describes two main types of circulatory systems - open systems where blood mixes with interstitial fluid, and closed systems where blood remains confined to vessels. Vertebrates have a closed dual circuit system, with one circuit moving blood to and from the lungs, and another moving blood to and from the rest of the body. The human cardiovascular system consists of a heart that pumps blood through arteries, capillaries and veins in two separate circuits - the pulmonary and systemic circuits.

Introduction_to_the_CVS.pdf
The cardiovascular system comprises the heart, blood vessels, and blood. It transports nutrients to tissues and removes waste products. The heart pumps blood through a closed system of arteries, capillaries, and veins. Arteries carry oxygenated blood away from the heart while veins carry deoxygenated blood back to the heart. The document provides detailed descriptions of blood components and the structure and function of the heart and different types of blood vessels that make up the cardiovascular system.
Circulatory System.pptx
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through two circuits - pulmonary circulation and systemic circulation. In pulmonary circulation, deoxygenated blood leaves the right ventricle and is pumped to the lungs where carbon dioxide is released and oxygen absorbed. Oxygenated blood then returns to the left atrium. In systemic circulation, oxygenated blood leaves the left ventricle and is pumped through arteries to tissues throughout the body, where oxygen is delivered and carbon dioxide and waste are collected and returned to the right atrium via veins.
urinary system.pptx
The adrenal gland is divided into the medulla and cortex. The medulla releases catecholamines in response to sympathetic input. The cortex produces mineralocorticoids, glucocorticoids, and sex steroids. The kidneys filter blood and produce urine through nephrons in the cortex and medulla. They are supplied by the renal artery and drained by the renal vein. The ureters carry urine from the kidneys to the bladder. The bladder stores urine until urination. The urethra then carries urine from the bladder out of the body.
Bio report
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through arteries and veins, circulating oxygen and nutrients to tissues and removing waste. It has four chambers and valves to ensure one-way blood flow. Blood contains red blood cells, white blood cells, and platelets in plasma. The circulatory system has three circuits: pulmonary, systemic, and coronary. Diseases can affect the heart and blood vessels. The document provides details on the structure and function of the circulatory system and common circulatory problems.
Circulation ppt
The circulatory system consists of the blood circulatory system and lymphatic system. The blood circulatory system contains blood, heart, and blood vessels. Blood is a connective tissue composed of plasma, red blood cells, white blood cells, and platelets. Plasma is 90-92% water and contains proteins like albumins, globulins, and fibrinogen. Red blood cells are biconcave and transport oxygen and carbon dioxide. White blood cells help fight infection. The heart has four chambers and uses double circulation to oxygenate blood in the lungs and transport it to the body before repeating the cycle. Lymph flows unidirectionally through lymph vessels and drains excess fluid from tissues.

11. Transportation in Animals and Plants by Dilip Kumar Chandra
The document discusses transport systems in animals and plants. It describes how circulatory systems transport oxygen, nutrients, wastes, and other materials throughout animal bodies using blood, blood vessels and the heart. The circulatory system consists of arteries, veins and capillaries. Arteries carry oxygen-rich blood away from the heart while veins carry deoxygenated blood back to the heart. Transport of water and nutrients in plants occurs through xylem tissue while transport of food occurs through phloem tissue. Transpiration through leaves generates suction that transports water through xylem vessels in plants.

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.
