9. Parts of the Heart and Their
Function
The heart is a remarkable organ responsible for pumping oxygen-rich blood
throughout the body. Let's explore its anatomy and functions.
by Jerry Arnado

10. An Overview of the Heart
The heart is a muscular organ located in the chest and is divided into four
chambers: two atria and two ventricles. It plays a vital role in circulating blood,
ensuring the delivery of nutrients and oxygen to all body tissues.

11. The Structure of the Heart
Chambers
The heart consists of four
chambers: two atria and two
ventricles. The atria receive
blood, while the ventricles
pump blood out of the heart.
Valves
The heart has four valves that
ensure blood flows in the right
direction. The mitral and
tricuspid valves control blood
flow between the atria and
ventricles, while the aortic and
pulmonary valves regulate
blood flow out of the heart.
Coronary Arteries
The coronary arteries supply
the heart muscle with oxygen-
rich blood. They branch off the
aorta and encircle the heart,
ensuring its own blood supply.

12. Function of the Atria
1 Blood Collection
The atria receive oxygen-poor blood returning from the body and lungs.
2 Contract and Push
The atria contract, pushing blood into the ventricles while the valves prevent backflow.

13. Function of the Ventricles
1 Powerful Pumps
The ventricles are responsible for
pumping blood to the body and lungs.
2 Contraction and Ejection
The ventricles contract, forcing blood out
of the heart through the aorta and
pulmonary artery.

14. Role of the Valves
1 Prevent Backflow
The valves ensure one-way blood flow,
preventing backflow and ensuring
efficient circulation.
2 Timing Mechanism
The valves open and close at specific
intervals, coordinated with the heart's
electrical system.

15. Conclusion
The heart is a complex organ with various parts, each essential for its proper
function. Understanding its structure and functions helps us appreciate the
intricacies of this remarkable machine.

16. Discover the Wonders
of the Lungs
The lungs are remarkable organs that enable the vital process of
respiration. Let's explore their intricate anatomy and the crucial role they
play in our overall health.
by Jerry Arnado

17. Introduction to the Lungs
The lungs are essential for breathing, allowing us to take in oxygen and
expel carbon dioxide. Incredibly, they have a surface area roughly the
size of a tennis court!

18. Anatomy of the Lungs
Respiratory System
The lungs are part of the
respiratory system, along
with the airways and
diaphragm - all working
together to facilitate
breathing.
Chest Cavity
The lungs are housed in the
chest cavity, protected by the
ribcage, and separated from
the abdomen by the
diaphragm.
Lobes within Lungs
Each lung is divided into
lobes. The right lung has
three lobes, while the left
lung has two to
accommodate the heart.

19. Bronchi and Bronchioles
Major Airways
The bronchi are the main
airways that branch out
from the trachea, entering
the lungs and further divide
into smaller tubes called
bronchioles.
Air Distribution
The bronchial tree is
responsible for
distributing air to all parts
of the lungs, ensuring
efficient oxygenation.
Mucus Production
The bronchi and
bronchioles are lined with
tiny hairs called cilia, which
help remove mucus and
foreign particles from the
airways.

20. Alveoli and Their Function
Alveoli
Tiny sacs at the end of bronchioles where
gas exchange takes place between the
lungs and the bloodstream.
Surface Area
The multitude of alveoli greatly increases
the surface area available for oxygen and
carbon dioxide exchange.
Capillaries
The walls of the alveoli are surrounded by
capillaries, allowing for efficient transfer of
oxygen into the bloodstream and removal
of carbon dioxide.
Gas Exchange
Oxygen from inhaled air diffuses into the
capillaries, while carbon dioxide from the
bloodstream moves into the alveoli to be
exhaled.

21. Discovering the Wonders
of the Kidneys
Let's dive into the anatomy and functions of one of our vital organs: the
kidneys. Learn how they regulate our body's balance and keep us healthy.
by Jerry Arnado

22. Anatomy of the Kidneys
Renal Cortex
The outer layer of the kidney that
filters blood and removes waste.
Renal Pelvis
The center of the kidney where
urine is collected and flows into
the ureter.
Bladder
The hollow muscular organ that
stores urine until it is eliminated
from the body.

23. Functions of the Kidneys
1 Fluid Balance 🌊
The kidneys control the
amount of fluid in your
body by regulating water
absorption and excretion.
2 Waste Elimination 🗑️
Kidneys filter blood and
remove waste such as
excess salts, urea, and
other harmful toxins.
3 Blood Pressure
Regulation ⬆️⬇️
The kidneys release
hormones that regulate
blood pressure and
maintain a healthy
balance of salt and water
in the body.

24. Renal Cortex and Renal Medulla
1 Renal Cortex
The outer layer of the kidney that
contains over 1 million nephrons where
filtration occurs.
2
Renal Medulla
The inner portion of the kidney
composed of renal pyramids containing
collecting ducts that transport urine to
the renal pelvis.

25. Nephrons and Their Role
Filtration
As blood enters each nephron, it is filtered by glomeruli to remove waste and excess fluids.
Reabsorption
Healthy substances such as glucose and amino acids are reabsorbed into blood while
excess water and harmful wastes remain in the tubule to become urine.
Secretion
The final stage where urine is transported to the renal pelvis and ureters, ready for
elimination from the body.
