The circulatory system transports blood throughout the body using the heart and blood vessels. The heart pumps blood into arteries which branch into smaller arterioles and capillaries where nutrients and oxygen are exchanged, then blood returns to the heart through veins. Blood contains red blood cells, white blood cells, platelets suspended in plasma which carries nutrients, waste, hormones, and antibodies. The circulatory system allows for transportation of these materials to sustain life.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
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

Circulatory system
1.
2. The
Circulatory System is
responsible for transporting materials
throughout the entire body. It
transports nutrients, water, and
oxygen to your billions of body cells
and carries away wastes such as
carbon dioxide that body cells
produce. It is an amazing highway
that travels through your entire body
connecting all your body cells.
5. The
heart pumps blood by contracting
and relaxing. It is a hollow muscular
organ. It is about the size of your fist
and located in the middle of the chest
cavity. It is composed of cardiac
muscles that contract involuntarily. It is
located between the lungs and
protected by the rib cage.
6.
7.
8. Right Atrium - It receives
deoxygenated blood from the body
Right Ventricle - Receives
deoxygenated
blood from the right
atrium and pumps
the blood to the
lungs for oxidation
Left Atrium - It receives oxygenated
blood from the right and left lungs
through the pulmonary veins.
Left Ventricle - It receives oxygenated
blood from the left atrium, and pumps
blood to all parts of the body.
9. Ventricular septum - the wall between the
right and left ventricles of the heart.
Atrial septum - is the wall of tissue
that
separates the right and left atria of the
heart.
Pulmonary vein - is a large blood vessels
that carries blood from the
lungs to the
left atrium of the heart.
Pulmonary arteries - carry deoxygenated
blood from the heart
to the lungs.
10. Superior Vena Cava(precava or SVC) is truly superior, a large diameter,
yet
short, vein that carries deoxygenated blood
from the upper
half of the body to the
heart's right atrium.
Inferior Vena Cava(posterior vena cava or
IVC) - is the large vein that carries
deoxygenated blood from the lower half
of the body to the heart’s right
atrium.
Aorta - is the largest artery in the body and
pumps blood throughout
the body.
11. Tricuspid Valve - is located between
the
right atrium and right ventricle
and
ensures the flow of blood from
the right
atrium into the right
ventricle prevents
the reverse.
Mitral valve(bicuspid valve or left
atrioventricular valve) - is a dual-flap
valve in the heart that lies between the
left atrium and the left ventricle.
Mitral Valve + Tricuspid Valve =
atrioventricular valves.
12.
Aortic valve - It is normally tricuspid
(with three leaflets), although in 1% of
the population it is found to be
congenitally bicuspid (two leaflets). It
lies between the left ventricle and the aorta.

14. Blood
is a specialized bodily fluid in
animals that delivers necessary
substances such as nutrients and
oxygen to the cells and transports
metabolic waste products away
from those same cells.
Blood is also known as the “Red
River Of Life”
15. Transports
oxygen from lungs to body
Transports carbon dioxide from the
tissue back to the lungs
Transports nutrients from the
digestive
tract to the tissue
Transports wastes and excess water the
tissue to the kidneys
Transports antibodies to the tissues
Helps regulate body temperature
16.
17. Solid Parts: Red Blood Cells, White Blood Cells, and Platelets
Liquid Part: Plasma
18.
19. Red
blood cells (also referred to as
erythrocytes) are the most common type
of blood cell. It contains an iron
compound called hemoglobin which give
them their red color. The RBC transports
oxygen from the lungs to different cells of
the body and carbon dioxide as waste
product which they carry back to the lungs
where it is expelled.
20. White
blood cells(also referred to as
erythrocytes) act as soldiers of the body.
They travel in the blood stream but do
most of their work in the tissue. The
approximate white blood cells in the blood
should a person have is 5 000 to 10 000
per cubic millimeter of blood. It is
produced in the lymph nodes, spleen and
bone narrow.
21. – ingest and kill bacteria
Lymphocytes – produce
antibodies to fight foreign cells
Monocytes- are large scavenger
cells that clear tissue spaces of
dead and foreign matter
Neutrophils
22. Platelets, or thrombocytes are small,
irregularly shaped clear cell fragments, 2–
3 µm in diameter, which are derived from
fragmentation of precursor
megakaryocytes. The average lifespan of a
platelet is normally just 5 to 9 days. Platelets
are a natural source of growth factors.
It the agent of blood clotting
23.
24. Plasma
is the liquid part which
comprises 55% of blood. Plasma
caries antibodies to the tissue,
transports waste material from the
body cells to the lungs, liver, kidneys;
it contains fibrinogen which helps the
blood clot when the blood gets
injured.

31. An
artery is an elastic blood vessel that
transports blood away from the heart.
Arterioles is the smallest arteries and
they play a vital role in
microcirculation. Microcirculation
deals with the circulation of blood from
arterioles to capillaries to venules (the
smallest veins).
32. Pulmonary
arteries - carry blood
from the heart to the lungs where the
blood picks up oxygen. The
oxygen
rich blood is then returned to the heart
via the pulmonary
veins.
Systemic arteries - deliver blood to the
rest of the body. The aorta is
the main
systemic artery and the
largest artery
of the body
33. A vein
is an elastic blood
vessel that transports blood
from various regions of the
body to the heart. Venules is
the smallest veins in the body.
34.
Pulmonary veins - carry oxygenated blood from
the lungs to the left atrium of the heart.
Systemic veins - return deoxygenated blood from
the rest of the body to the right
atrium of the
heart.
Superficial veins - are located close to the
surface of the skin and are not located
near
a corresponding artery.
Deep veins - are located deep within muscle
tissue and are typically located near a
corresponding artery with the same name (for
example coronary arteries and veins).
35. A capillary
is an extremely small blood
vessel located within the tissues of the
body, that transports blood from arteries
to veins. Capillaries are most abundant in
tissues and organs that are metabolically
active. For example, muscle tissues and
the kidneys have a greater amount of
capillary networks than do connective
tissues.
38. It
is a decrease in number
of red blood cells (RBCs) or
less than the normal
quantity of hemoglobin in
the blood.
39. Polycythemia
is overpopulation
of red blood cells. Too many red
blood cells will make the blood
too thick so the blood movement
through the cells is to slow or
sluggish
42. The
thrombocytopenia is a disease in
which the are to few blood platelets. The
blood tends to seep out of the circulatory
system, making black and blue bruise
spot and tiny pinprick-sized blood spots.
This happens because there are not
enough platelets to plug up small breaks
in the capillaries in which if not covered
fatal bleeding may occur.
43. Hemophilia
is failure of blood
to clot properly. This is
hereditary disease occurring
exclusively in males and
transmitted directly only by
females.
44. Congenital
heart disease is a
general term for a range of birth
defects that affect the normal
workings of the heart. Congenital
means that a condition is present
at birth.
45. Rheumatic
heart disease is a condition
in which permanent damage to heart
valves is caused from rheumatic fever.
The heart valve is damaged by a disease
process that begins with a strep throat
caused by streptococcus A bacteria, that
may eventually cause rheumatic fever.
46. High
blood pressure (also called
hypertension) occurs when your
blood moves through your
arteries at a higher pressure than
normal.
47. Coronary artery disease, is a condition in
which plaque builds up inside the coronary
arteries. These arteries supply oxygen-rich
blood to your heart muscle.
Plaque is made up of fat, cholesterol,
calcium, and other substances found in the
blood. When plaque builds up in the arteries,
the condition is called atherosclerosis. The
buildup of plaque occurs over many years.
48.
49.
Systemic circulation is the part of the
cardiovascular system which carries
oxygenated blood away from the heart to the
body, and returns deoxygenated blood back
to the heart. This physiologic theory of
circulation was first described by William
Harvey. This term is opposed and
contrasted to the term pulmonary circulation
first proposed by Ibn al-Nafis.
50. Pulmonary
circulation is the
portion of the cardiovascular
system which carries oxygendepleted blood away from the
heart, to the lungs, and returns
oxygenated blood back to the
heart.
51.
52. Dead blood platelets release a certain
enzyme from which the blood protein called
thromboplastin is formed
In the presence of thromboplastin, calcium
ions, and Vitamin K, the blood protein
prothrombin becomes thrombin.
The union of thombin and blood protein
fibrogenis changed into fibrin in which the
fibrin fibers from the thread like network and
traps more platelets and blood cells
eventually becoming clot that plugs the cut.
