The heart has four chambers. The two superior receiving chambers are the atria (= entry halls or chambers), and the two inferior pumping chambers are the ventricles (= little bellies).
On the anterior surface of each atrium is a wrinkled pouchlike structure called an auricle
The cardiovascular system can be thought of as the transport system of the body.
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.
gross Anatomy of kidney, description of external and internal structure of kidney, the relation of right and left kidney. difference between right and left kidney, and some clinical abnormalities relate to kidney,
This presentation covers internal structures of heart like atria and ventricles & external structures like emerging blood vessels and grooves on the heart. I hope this PPT will be helpful for instructors as well as teachers.
In this presentation there is the complete basic anatomy of the Heart. in this presentation there is complete description of heart including anatomy, external feature, relations of the heart, layers of heart, structure and functions of heart, circulation of heart, blood supply and nerve supply of the heart is explained in the simplest form which is very useful for the students who are appearing for the various medical entrance exams like medical, dental, physiotherapy, ayurved, pharmacy, nursing and also beneficial for the students who are doing preparation for NEET and other medical entrance

The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
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.

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.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

heart anatomy
1. Anatomy of the heart
The heart is located within the bony thorax
and is flanked on each side by lungs.
The apex is directed toward the left hip and
rests on the diaphragm-in 5th
intercostal
space.
2.
3. The base (posterosuperior aspect),
from which the great vessels of the
body emerge, points toward the right
shoulder and lies beneath the second
rib.
4.
5. Coverings of the heart
Double sac of serous membrane, the
pericardium
Thin visceral pericardium, or epicardium
(hugs the external surface of the heart-
part of heart wall)
6. Parietal pericardium, dense fibrous
connective tissues (protect the heart-
anchors to it’s surrounding structures.
Serous fluid is produced by the serous
pericardial membrane.
7. Wall of the heart
Outer epicardium(visceral pericardium)
Myocardium consist of thick bundles of
cardiac muscle twisted (contraction)
8.
9. Endocardium is a thin sheet of
endothelium that lines the heart
chambers (continous with lining of
blood vessels)
10. Chambers and associated
vessels
Two atria and two ventricles.
The superior atria are receiving
chambers.
The inferior,thick-walld ventricles are
discharging chambers (actual pump of
the heart).
11. The right ventricle forms most of
anterior surfaces… the left ventricle
forms the apex.
Interatrial or interventricular septum
divides the heart longitudinally.
12. Valves
Four valves, which allow blood to flow in
only one direction.
The atrioventricular, or AV valves are
located between the atrial and
ventricular chambers on each side.
The AV valves prevent backflow into
the atria when ventricles contract.
13. The AV valve-bicusped or mitral valve
consist of two cusp, or flaps, of
endocardium.
The right AV valve, the tricusped valve,
has three cusps.
Chordae tendineae : tiny white cord –
anchor the cusps to the wall of the
ventricles
14. Semilunar valves (three cusps) (pumonary
and aortic valves), guards the bases of two
large arteries leaving the ventricular
chambers.
15. Cardiac circulation
Single organ
Heart function as a double pump
Pulmonary circulation
Systemic circulation
16.
17. Pulmonary circulation
The right side works as the pulmonary
circuit pump.
It receives oxygen-poor blood from the
veins of the body through superior and
inferior venae cavae and pumps it out
through the pulmonary trunk.
18. From pulmonary trunk to right and left
pulmonary arteries , which carry blood
to the lungs, where oxygen is picked up
and carbon dioxide is unloaded
Oxygen-rich blood drains from the lungs
and is returned to the left side of the
heart through the four pulmonary veins.
20. Systemic circulation
Blood returned to the left side of the
heart is pumped out of the heart into
the aorta to systemic arteries branch to
supply all body tissues
21. Function of the systemic
circulation
It supplies oxygen- and nutrient-rich
blood to all body organs.
22. Blood supply of the heart
Coronary arteries : are branches from
the base of the aorta and encircle the
heart in the atrioventricular groove
Right coronary artery :posterior
interventricular and marginal arteries
Left coronary artery:anterior
interventricular and circumflex arteries
23. Cardiac veins drains into coronary sinus
then to right atrium.
