HELLO THIS A PPT ON HUMAN BODY

1. Hello everyone my name is Aarvin
Gupta, so in this presentation I
would show u that how human
body works .

2. To understand human body we
have to understand it’s organ
systems for eg. Digestive,
respiratory, circulatory systems etc.
So lets get started.

3. There are 11 major systems in a human body
which are the integumentary, skeletal,
muscular, nervous, endocrine, cardiovascular,
lymphatic, respiratory, digestive, urinary, and
reproductive systems. But I have studied only 7
types of systems which are the following :

4. 1. Digestive System
2. Respiratory System
3. Circulatory System
4. Nervous System
5. Muscular System
6. Skeletal System
7. Excretory System

5. Digestion involves the breakdown of food into smaller
and smaller components, until they can be absorbed and
assimilated into the body. The process of digestion has 5
stages. In simple words the organs that take in food and
liquids and break them down into substances that the
body can use for energy, growth, and tissue repair.
Waste products the body cannot use leave the body
through bowel movements. Images shown on next slide.

7. Respiratory system is the network of organs and tissues that
help you breathe. This system helps your body absorb oxygen
from the air so your organs can work. Humans have two type
of respiration aerobic and anaerobic respiration. It also cleans
waste gases, such as carbon dioxide, from your blood. Common
problems include allergies, diseases or infections. Human
respiratory system includes the following

9. The circulatory system is made up of blood vessels
that carry blood away from and towards the heart.
Arteries carry blood away from the heart and veins
carry blood back to the heart. The circulatory
system carries oxygen, nutrients, and hormones to
cells, and removes waste products, like carbon
dioxide. It includes heart, blood, blood vessels etc.

11. The nervous system is the part of an animal's body that
coordinates its behavior and transmits signals between
different body areas. In vertebrates it consists of two
main parts, called the central nervous system (CNS) and
the peripheral nervous system (PNS). The CNS contains
the brain and spinal cord. The PNS contains The nerves
that branch off from the spinal cord and extend to all
parts of the body. It contains brain, spinal cord, nerves
and sense organs.

13. The muscular system is an organ system consisting of
skeletal, smooth and cardiac muscles. It permits
movement of the body, maintains posture and
circulates blood throughout the body. It contains
muscles and tendons.

15. The skeletal system includes all of the bones and joints
in the body. Each bone is a complex living organ that
is made up of many cells, protein fibers, and minerals.
The skeleton acts as a scaffold by providing support
and protection for the soft tissues that make up the
rest of the body. It includes bones, cartilage,
ligaments, bone marrow.

17. The excretory system is the system of an
organism's body that performs the function of
excretion, the bodily process of discharging
wastes. The Excretory system is responsible for
the elimination of wastes produced by
homeostasis.

19. NOW WE WILL SEE THAT HOW THESE ALL ORGAN SYSTEM
WORKS

20. Now lets learn what is biological organisation. That
how ecosystem is formed.
First comes the cell, group of cells form tissue then
group of tissues form organs then group of it forms
organ system and group of it forms a human body
then comes a population and then different
population form a community and this forms
ecosystem

21. ACCORDING TO ME THE MOST WANTED ORGANS
OF A HUMAN BODY ARE THE BRAIN AND HEART .
NOW I WILL EXPLAIN THERE FUNCTIONS.

22. It's the muscle at the center of your circulation system, pumping
blood around your body as your heart beats. This blood sends
oxygen and nutrients to all parts of your body, and carries away
unwanted carbon dioxide and waste products. So The four
major functions of the heart are:
•To transport nutrients, gases and waste products around
the body.
•To protect the body from infection and blood loss.
•To help the body maintain a constant body temperature
('thermoregulation')
•To help maintain fluid balance within the body.

23. The brain controls our thoughts, memory and speech, movement of
the arms and legs, and the function of many organs within our
body. The central nervous system (CNS) is composed of the brain
and spinal cord.
Functions of a Brain are :
•Attention and concentration.
•Self-monitoring.
•Organization.
•Speaking (expressive language)
•Awareness of abilities and limitations.
•Mental flexibility.
•Inhibition of behavior.

24. 1.Eat healthy.
2.Get active.
3.Stay at a healthy weight.
4.Quit smoking and stay away from secondhand smoke.
5.Control your cholesterol and blood pressure.
6.Drink alcohol only in moderation.
7.Manage stress.

25. 1.Exercise your body. Research shows that exercise:
...
2.Exercise your brain. If you want to stay sharp, use
your brain now, and don't stop. ...
3.Eat a healthy diet. A healthy diet will
help keep your brain healthy, and help your heart,
too. ...
4.Socialize.
