The document discusses several body systems involved in homeostasis. It explains that homeostasis refers to maintaining relatively stable internal conditions despite external changes. Feedback loops allow the body to sense changes and respond to keep conditions like temperature, blood sugar, and pH levels balanced. The nervous, digestive, urinary, circulatory, and respiratory systems all contribute to homeostasis through feedback mechanisms. Key organs like the hypothalamus, liver, kidneys, and capillaries monitor levels and trigger responses to maintain homeostasis when levels deviate from their normal ranges. Diseases can disrupt homeostasis if systems are damaged or not functioning properly.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

micro teaching on communication m.sc nursing.pdfAnurag Sharma
Microteaching is a unique model of practice teaching. It is a viable instrument for the. desired change in the teaching behavior or the behavior potential which, in specified types of real. classroom situations, tends to facilitate the achievement of specified types of objectives.
2. Definition
Homeostasis is:
According to your Biology book: a process by
which organisms keep internal conditions
relatively constant despite changes in external
environments. Maintained by feedback loops.
3. Feedback Loop
Our body utilizes negative feedback loops
the most.
This is when the amount of product of a
reaction controls how fast (or slow) the
reaction goes.
In negative feedback, change in the
controlled value (body temperature, for
example) initiates responses that bring the
function of the organ back to within the
normal range (shivering or sweating).
4. In other words….
Negative feedback loops are like a
thermostat in your house.
If the temperature inside the house drops
below the point at which the thermostat is
set and the thermostat turns on the
furnace.
As the temperature within the house rises,
the thermostat again senses this change
and turns off the furnace when the
programmed temperature is reached.
5. What we need to keep the same in
our body:
Temperature (98.6 F)
Blood pH (7.4) almost neutral
Blood pressure (average 120/80)
Heart rate (80 beats per minute)
Blood sugar level
Hydration/amount of water
Amount of salts
Amount of blood (2 pints per every 25 lbs)
6. What it really means (in English!)
The human body needs to maintain things
like body temperature (98.6 F). If you get
too hot or cold then your body will not
thrive.
Too hot and your brain will overheat and
―cook‖
Too cold and your body’s systems will shut
down
7. Each system of the body contributes some
aspect to maintaining homeostasis (stable
internal balance)
9. Nervous System
Central Nervous System
Brain and spinal cord: The brain is like your
body’s central computer and the spinal cord is
the network that the nervous system uses to
send messages to and from the body.
Peripheral Nervous System
All the nerves and neurons throughout the
body: Sensory neurons (cells) send signals to
the brain and then the brain instructs motor
neurons to move/react.
10. Autonomic Nervous System subdivided
into the:
Sympathetic – responds to stress and danger.
―Fight or Flight‖ response…release of
adrenaline
Parasympathetic – dominant during sleep.
Controls all functions that just ―happen‖ like
heart beating, breathing, and digestion.
11. Nervous System
Hypothalamus - controls body
temperature with the following feedback
loop:
If too low, causes shivering of muscles and
reduced blood flow (blue skin) to create heat
If too hot, causes sweating and increased
blood flow (red skin) to get rid of heat
12. Brain Stem - Controls heart rate with the
following feedback loop:
If too low, increases nerve impulses to make
heart beat faster
If too high, decreases nerve impulses to keep
the heart rate at 80 beats per minute
13. Diseases/afflictions of the nervous
system
Stroke
Aneurism
Brain Cancer
Depression
Bipolar disorder
headaches
16. Digestive System
The digestive system is made up of the
digestive tract—a series of hollow organs
joined in a long, twisting tube from the
mouth to the anus—and other organs that
help the body break down and absorb
food
17. Organs that make up the digestive tract
are the mouth, esophagus, stomach, small
intestine, large intestine—also called the
colon—rectum, and anus.
Inside these hollow organs is a lining
called the mucosa. In the mouth,
stomach, and small intestine, the mucosa
contains tiny glands that produce juices to
begin the process of digestion.
The digestive tract also contains a layer of
smooth muscle that helps break down
food and move it along the tract.
18. Two ―solid‖ digestive organs, the liver and
the pancreas, produce digestive juices
that reach the intestine through small
tubes called ducts.
The gallbladder stores the liver’s digestive
juices until they are needed in the
intestine.
19. The small intestine allows the broken
down food (in the form of glucose and
other molecules of life) to be absorbed by
the bloodstream and transported to all
parts of the body.
The large intestine allows water to be
reabsorbed by the body. All leftover
wastes are left over to be excreted out of
the body.
Parts of the nervous and circulatory
systems also play major roles in the
digestive system.
20. Digestive System
Liver – Controls blood sugar level with the
following feedback loop:
If too low, converts stored glycogen (glucose)
into sugar
If too high, removes sugar from the blood
and stores as glycogen
21. Diseases/afflictions of the digestive
system
Diabetes
Ulcers
Acid reflux/heartburn
Stomach or liver cancer
Cavities/gum disease/root canal
Tonsillitis
Gall stones/gall bladder removal
22. Urinary/Excretory
System
Besides getting rid of wastes and
filtering toxins out of the blood, it
also…..
23. Urinary/Excretory System
Works closely with the digestive,
circulatory and nervous systems.
As the heart pumps blood around the
body, the blood carries fresh oxygen to
various cells and organs, then picks up
waste products like carbon dioxide, salt
and urea.
There is an artery and a vein that runs
into and out of each kidney to take the
blood there and back.
24. As the waste products arrive, the kidneys
perform a filtration process that removes
hazardous toxins and products that the
body can not use from water and nutrients
that can be reclaimed and recycled.
The kidneys return the reclaimed water
back to the body, but mix the waste
products into a liquid waste compound
known as urine.
25. The kidneys direct the urine to the
bladder, where it is collected and held
until it is either manually expelled or
forced out by involuntary muscle
contractions.
26. The excretory system takes advantage of
sweating by providing waste liquids to
accomplish the cooling effect.
Sweat is not pure water; instead, it is a
solution of approximately 94 percent
water and six percent waste products.
By excreting weak urine through the skin's
pores, the excretory system can perform
the dual functions of ridding the body of
waste products while also keeping it cool.
27. Urinary/Excretory System
Kidneys - Controls amount of water and
salt in body with the following feedback
loop:
If too low, retains water/salt and keeps them
from going to the bladder
If too high, pushes more water and salt into
the bladder
28. Diseases/afflictions of the
urinary/excretory system
Diarrhea
UTI infection
Colon Cancer
Constipation
Kidney stone
Flatulence
incontinence
31. Circulatory/Cardiovascular
System
The main function of the circulatory
system is to provide nutrients and oxygen
to the various parts of the body, via the
blood, which is circulated through the
veins and arteries, like a giant
transportation system.
Arteries carry the oxygenated blood from
the heart to the cells and tissues, whereas
veins return the oxygen-depleted blood
from the cells to the heart.
32. The Two forms of Circulation
In systemic circulation, arteries collect the
oxygen-rich blood from the heart and is
transported to the body tissues. In the
process, oxygen from the blood is diffused
into the body cells; whereas carbon
dioxide from the cells is diffused in the
blood. This exchange of gases takes place
with the help of capillaries that surround
the body cells
33. The pulmonary circulation is a loop from
the heart to the lungs. It is that portion,
where deoxygenated blood from the heart
is carried to the lungs and in turn, returns
oxygenated blood to the heart.
34. The circulatory system works with the
respiratory system and digestive system to
supply oxygen and nutrients to the body.
Blood carries the messenger chemicals -
hormones, secreted by the organs of the
endocrine system. Thus, the circulatory
system is also responsible for circulating
hormones for proper communication
between the body organs.
35. Circulatory/Cardiovascular System
Capillaries (smallest of blood vessels) -
Controls flow of oxygen to cells and
carbon dioxide from cells using the
following feedback loop:
If oxygen too low, gases flow from areas of
high concentration (capillaries)to low
concentration (cells) to maintain levels
If too high, the opposite happens, gases flow
from areas of high concentration (cells) to low
concentration (capillaries).
36. Diseases/affliction of the
cardiovascular/circulatory system
Heart attack
High blood pressure
Hemophilia
Stroke
Sepsis (infection)
Bruises/contusions (hickey)
38. Respiratory System
Air first enters your body through your nose
or mouth, which wets and warms the air.
(Cold, dry air can irritate your lungs.) The air
then travels through your voice box and
down your windpipe. The windpipe splits into
two bronchial tubes that enter your lungs.
A thin flap of tissue called the epiglottis
covers your windpipe when you swallow. This
prevents food or drink from entering the air
passages that lead to your lungs.
39. Except for the mouth and some parts of
the nose, all of the airways have special
hairs called cilia that are coated with
sticky mucus. The cilia trap germs and
other foreign particles that enter your
airways when you breathe in air.
These fine hairs then sweep the particles
up to the nose or mouth. From there,
they're swallowed, coughed, or sneezed
out of the body. Nose hairs and mouth
saliva also trap particles and germs.
40. Within the lungs, your bronchi branch into
thousands of smaller, thinner tubes called
bronchioles. These tubes end in bunches
of tiny round air sacs called alveoli.
Each of these air sacs is covered in a
mesh of tiny blood vessels called
capillaries. The capillaries connect to a
network of arteries and veins that move
blood through your body.
41. The muscle that helps the lungs breath is
called the diaphragm. Breathing is
something that happens passively,
something that we don't even think
about...that is unless it is something that
becomes difficult to do.
42. Respiratory System
Lungs - Controls blood pH, amount of
carbon dioxide in blood using the following
feedback loop:
If gets too low (acidic, pH below 7.4), gets rid
of excess CO2 (which caused the acid)
If gets too high (basic, pH above 7.4), retains
more CO2
43. Diseases/afflictions of the
respiratory system
Cold/flu
Pneumonia
Asthma
Lung cancer
Sinus infection
allergies
46. Skeletal System
The skeletal system offers protection,
support, blood cell formation, stores
minerals and energy and aids movement.
Calcium and phosphorus are stored within
your bones.
47. Bones are considered to be living organs
because they are made up of nerve,
muscle and epithelial tissue, as well the
connective tissue that binds everything
together.
If you were to look at the cross section of
a long bone, such as your femur, you
would see a shaft that contains either red
or yellow marrow. Red is newly produced
marrow. As bones age, the red marrow
converts into yellow. This special, yellow
marrow is an energy source.
48. Within the bones, red and white blood
cells are produced, along with platelets.
There is a fibrous sheath called a
periosteum that contains blood vessels
which supply oxygen and nutrients to the
bone tissues.
Blood vessels get in and out of the bones
by little openings called nutrient canals.
49. Skeletal System
Bone Marrow - Controls blood levels using
the following feedback loop: 2 pints for
every 25 pounds
If too low (2 pints for every 25 pounds), bone
marrow produces necessary white and red
blood cells.
50. Diseases/afflictions of the skeletal
system
Broken/fractured bones
Anemia (low RBC and/or iron)
Osteo arthritis
Torn ligament(s)
Torn cartilage
sprains
52. Muscular System
The muscles in our body are divided into
three classes: cardiac, smooth, and
skeletal.
Muscles often work in pairs so that they
can pull in different or opposite directions.
The cells that make up muscles contract &
then relax back to their original size.
Tiny microscopic fibers in these cells
compress by sliding past each other like a
sliding door being opened & shut again.
53. At every joint, tendons and ligaments also
help out. Muscles wouldn't be very useful
alone because they don't directly connect
to the bone, so even if they contract, they
wouldn't be moving anything.
Muscles are connected to tendons, which
are connected to the bones. When the
muscles contract, they pull on the
tendons, which in turn pull on the bones,
and that causes movement.
54. But without ligaments, that movement
wouldn't be too useful because it would
not be directed movement.
Without ligaments, instead of bones
bending or rotating about each other
when muscles contract, they would slide
by each other. Ligaments are what hold
the bones together. They connect at the
ends of muscles and keep them from
slipping and sliding, and force them to
bend.
55. The muscular system interacts with other
systems of the body.
During inhalation, the muscles between
the ribs relax, allowing the lungs to draw
in air.
When you digest food, muscles in your
esophagus interact with the digestive
system.
Your nervous system tells your muscles
when to move.
Even your skeletal system needs your
muscular system because your muscles
keep your bone structure intact
56. Muscular System
All muscles - Control body position using
the following feedback loop:
If muscle strength too low: Systems that rely
on the muscles to do the work necessary for
homeostasis (heart, lungs, brain, digestive
organs….) could not function
60. Lymph (Endocrine/Immune)
System
The immune system is made up of many
different cells, organs, tissues and
substances within your body.
Each aid in eliminating foreign organisms
from your body and protecting you from
various diseases and illnesses.
These foreign organisms come in the form
of viruses, bacteria, parasites and fungi.
They are known as ―microbes.‖
61. First Line of Defense – The Skin
The skin is thick and very hard to penetrate
and produces a variety of substances that
are harmful to invaders.
The eyes, nose, and mouth are protected by
fluids or sticky mucus that capture harmful
attackers.
The respiratory tract has cilia, tiny hairs that
remove particles.
Intruders that get as far as the stomach are
up against a sea of stomach acid that kills
most of them.
62. Second Line of Defense – White
Blood Cells
There are several types of immune cells,
each possessing specific duties and
characteristics. Several travel through the
body killing foreign substances as they
find them.
Others patrol the gastrointestinal tract
lining and blood vessels, safeguarding
particular organs.
63. The lymphatic system, which includes the
lymph nodes, the spleen, bone marrow
and thymus gland, produces these cells
and transports them throughout the body.
Lymph nodes and the spleen serve as
filters designed to keep harmful organisms
out of the blood stream. Most immune
cells are produced in the bone marrow,
the thymus or the spleen.
64. Lymph (Endocrine/Immune)
System
Lymph Nodes - Controls against invaders
such as bacteria and viruses
Maintains/produces white bloods cells (B cells,
T cells) to battle against foreign cells in the
body. Prevents major illnesses from taking
over the body
65. Diseases/afflictions of the
lymphatic system
Lymphoma (cancer)
Leukemia (abnormal WBC)
Any other infections
acne
