The document provides information about the circulatory system including its structures and functions. It describes the heart, blood vessels (arteries, veins, capillaries), blood, and the two pathways of circulation. The pulmonary circulation carries blood to the lungs and back to the heart while the systemic circulation carries blood to the body and back to the heart. Interactive activities are suggested to help explain the circulatory system and components of blood.
The circulatory system is the system in the body that functions to conduct oxygen, nutrients, and wastes in the body. It si composed primarily of the heart as the main organ, the blood vessels, and the blood. The heart is the pumping organ of the body works night and day to keep the blood circulating in our body.

The circulatory system is an organ system that permits blood and lymph circulation to transport nutrients, oxygen, carbon dioxide, hormones, blood cells, etc. to and from cells in the body to nourish it and help to fight diseases, stabilize body temperature and pH, and to maintain homeostasis.
This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which returns excess filtered blood plasma from the interstitial fluid (between cells) as lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The more primitive, diploblastic animal phyla lack circulatory systems. The lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to get returned to the blood.

An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. Gymnosperm seeds are often configured as cones.
biological macromolecules large cellular components abundantly obtained naturally and are responsible for varieties of essential functions for the growth and survival of living organisms.
An organic fertilizer is a fertilizer that is derived from organic sources, including organic compost, cattle manures, poultry droppings and domestic sewage.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

– Carries blood that contains
waste and CO2
Exception pulmonary vein
– Blood not under much
pressure
– Valves to prevent much
gravity pull
Venules: larger than capillaries
19. Your Heart: The Vital Pump
At REST, the heart
pumps about 5
QUARTS of blood a
minute.
During EXTREME
EXERTION (exercise)
it can pump 40 quarts
a minute.
21. Structure of Heart
Four chambers
– Two upper (Atria)
Right Atria
Left Atria
– Two lower
(Ventricles)
Right Ventricle
Left Ventricle
22.
23. Bloods Path Through the Heart
Both Atria fill at same time
– Rt atrium receives oxygen POOR blood from
body via the vena cavas
– Left atrium receives oxygen RICH blood from
lungs through four pulmonary veins
After filled with blood atria contract,
pushing blood into ventricle
24. Both ventricles contract
Right ventricle contracts and pushes
oxygen-poor blood toward lungs,
against gravity,
through pulmonary arteries
25. Left ventricle contracts and forces oxygen
rich blood
out of heart through
aorta (largest vessel)

27. The Blood
Body contains 4-6 L
Consists of
– Water
– Red Blood Cells
– Plasma
– White blood cells and
platelets
28. Erythrocytes (RBC)
Transporters of
– Oxygen

Fibrin (sticky network of protein
fibers)
– Form a web trapping blood cells
31. Section 37-2
Blood Clotting
Break in Capillary Wall
Blood vessels injured.
Clumping of Platelets
Platelets clump at the site
and release thromboplastin.
Thromboplastin converts
prothrombin into thrombin..
Clot Forms
Thrombin converts
fibrinogen into fibrin, which
causes a clot. The clot
prevents further loss of
blood..
32. Blood Types
Massive loss of blood requires a transfusion
Four Types
– A
– B
– AB
– O
Inherited from your parents
34. What happens when you mix blood
types?
Plasma contains proteins that
correspond to the shape of the
different antigens
If you mix one type with the
wrong one, you get CLUMPING
Type O is the universal donor
Type AB is the universal acceptor
37. Rh Factor
Rhesus factor (Rh), also inherited
– Rh+ (have antigen)
– Rh- (NO antigen)
Can cause complications in pregnancies
– mother Rh- 1st baby Rh+ : blood mixes with
mother; mother’s body makes anti-Rh+
antibodies
– 2nd Rh + body attacks baby
– Now have medicine to prevent antibody
formation

• Pump, pump, pumps your Blood.
• The right atrium’s where the process begins, where the
CO2 Blood enters the heart.
• Through the tricuspid valve, to the right ventricle, the
pulmonary artery, and lungs.
• Once inside the lungs, it dumps its carbon dioxide and
picks up its oxygen supply.
• Then it’s back to the heart through the pulmonary vein,
through the atrium and left ventricle.
• Pump, pump, pumps your Blood.
