The cardiovascular system consists of the heart, blood vessels, and blood. It functions to transport nutrients, gases, hormones, and waste products throughout the body. The heart pumps oxygen-rich blood through arteries and oxygen-poor blood returns via veins. Blood flows through a closed circulatory loop, being pumped from the heart through arteries, passing through capillaries where gas exchange occurs, and returning to the heart via veins. The document provides details on the components, circulation patterns, and clinical relevance of the cardiovascular system.
The cardiovascular system is transport system of body
It comprises blood, heart and blood vessels.
The system supplies nutrients to and remove waste products from various tissue of body.
The conveying media is liquid in form of blood which flows in close tubular system.
Introduction to the Human Cardiovascular SystemNaeem Ahmad
Human cardiovascular system, organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes. It is a closed tubular system in which the blood is propelled by a muscular heart.

A transport system is a means by which materials are moved ('transported') from an exchange surface or exchange surfaces to cells* located throughout the organism.
This system has three main components: the heart, the blood vessel and the blood itself. The heart is the system's pump and the blood vessels are like the delivery routes. Blood can be thought of as a fluid which contains the oxygen and nutrients the body needs and carries the wastes which need to be removed.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

1. Introduction to the Human
Cardiovascular System
Dr. Rakesh Kumar Verma
Assistant Professor
Department of Anatomy
KGMU UP Lucknow
2. INTRODUCTION
The cardiovascular system is
transport system of body
It comprises blood, heart and
blood vessels.
The system supplies nutrients
to and remove waste
products from various tissue
of body.
The conveying media is liquid
in form of blood which flows
in close tubular system.
Figure 1-2(f)
3. FUNCTION OF CARDIOVASCULAR
SYSTEM
Transport nutrients, hormones
Remove waste products
Gaseous exchange
Immunity
Blood vessels transport blood
◦ Carries oxygen and carbon dioxide
◦ Also carries nutrients and wastes
Heart pumps blood through blood vessels
6. HEART
• Heart is a four chambered, hollow
muscular organ approximately the size
of your fist
• Location:
–Superior surface of diaphragm
–Left of the midline
–Anterior to the vertebral column, posterior
to the sternum
Chapter 18, Cardiovascular System 6
14. ARTERIES
Blood vessels that
carry blood away from
the heart are called
arteries.
They are the thickest
blood vessels and they
carry blood high in
oxygen known as
oxygenated blood
(oxygen rich blood).
16. CLASSIFICATION OF ARTEIES
• Elastic- e.g. (Aorta & its Major branches)
• Muscular -e.g.(Renal, Testicular, Radial, Tibial
etc.)
• Arterioles (<0.1 mm)-
Terminal arterioles
Meta-arterioles
Thoroughfare
channel/ preferred
17. CAPILLARIES (5-8 micron)
• The smallest blood
vessels are
capillaries and they
connect the arteries
and veins.
• This is where the
exchange of
nutrients and gases
occurs.
18. BODY CONTAINS TWO KINDS OF CAPILLARIES
• CONTINUOUS-SKIN, LUNG, SMMOTH MUSCLE,
CONNECTIVE TISSUES
• FENESTRATED- PANCREAS,ENDOCRINE GLANDS,
SMALL INTESTINE,CHOROID PLEXUS,CILLIARY
PROCESS etc.
20. VEINS
• Blood vessels that carry
blood back to the heart
are called veins.
• They have one-way
valves which prevent
blood from flowing
backwards.
• They carry blood that is
high in carbon dioxide
known as deoxygenated
blood (oxygen poor
blood).
21. VEINS
• Thin Walled
• Large irregular lumen
• Have valves
• Dead space around
• Types:
Large
Medium
Small
23. VEINS
• Veins without Muscular tissue:
Dural venous sinuses
Pial Veins
Retinal
Veins of erectile tissue of sex organs
Veins of spongy bones
24. VEINS
• Factors responsible for venous return:
1.Muscle contraction
2.Negative intrathoracic pressure
3.Pulsation of arteries
4. Gravity
5. Valves
25. ANASTOMOSIS
• Communication
between vessels
• ARTERIAL:
Actual( end to end &
convergent)-Palmar,
plantar, Circle of
Willis, Labial
Intestinal arcade, etc.
Potential-Coronary,
around joints etc.
27. END ARTERIES
• END ARTERIES:
1.Central artery of
retina
2. Arteries of spleen,
liver, kidneys,
metaphyses of long
bones
3. Central branches of
cerebral cortex
28. CIRCULATION
–Coronary circulation – the circulation
of blood within the heart.
–Pulmonary circulation – the flow of
blood between the heart and lungs.
–Systemic circulation – the flow of
blood between the heart and the cells
of the body.
–Fetal Circulation
29. SYSTEMIC AND PULMONARY
CIRCULATION
Pulmonary circulation
The flow of blood
between the heart
and lungs.
Systemic circulation
The flow of blood
between the heart
and the cells of the
body.

35. APPLIED
• Problems with the
cardiovascular
system are common,
but they don’t just
affect older people.
• Many heart
problems affect
children and
teenagers.
