in this ppt we have tell you about the biological importence of cells tissues and the organ system of the human body with different system like nervous system digestive system

2. How is the body organized?
Living things are made up of organized systems too.
Groups of cells work
together to form
tissues.
Cells are the
basic units of
life.
cell tissue organ
Groups of tissues work
together to form
organs.
Each specific cell is grouped with other cells similar in structure and function to
form tissues and ultimately organs:

4. Root hair cells Xylem vessels Red blood cells
Characteristics Unicellular found behind
root tip
Outgrowth of epidermal
cells
Row of cells
Vessels form a hallow
cylindrical tubes of cells
Flattened biconcave disc
No nucleus
Contains hemoglobin
5. Root hair cells Xylem vessels Red blood cells
Specialization Long and narrow thus
increases its surface area
Large vacuole with salt and
sugar solution making it
more concentrated than the
surrounding soil water
Cell wall thickened and
impregnated with lignin
Narrow lumen to aid capillary
action
Hallow vessel allows water
to fill it
Long vessel to reach
distances between root and
shoot
Shape and flexibility allows it
to pas through the
narrowest vessels
Shape increases surface area
for diffusion of oxygen
Cytoplasm with Hb to pick up
more oxygen
Lack of nucleus provides
more space for Hb
6. Root hair cells Xylem vessel Red blood cell
Functions Absorption of water and dissolved
minerals salts from the soil
Provides mechanical strength to plant
body
Conducts water and mineral salts
from root to shoot
Mainly to transport oxygen
in the hemoglobin to area in
the deprived of it
7. • Animal cells and plant cells can form tissues.
• A living tissue is made from a group of cells
with a similar structure and function, which all
work together to do a particular job. Here are
some examples of tissues:
• muscle
• the lining of the intestine
• the lining of the lungs
8. Animal tissues Plant tissues
muscle
bone
liver
skin
lung
mesophyll
phloem
xylem
Can you think of any more types of tissue?
11. Tissue type Types of cells Function
Epithelial tissues Layer of lining or cover
Cells usually placed end to end
Covers the external surface
Serves as a protective lining
Some form glands
E.g. Digestive gland
12. Tissue types Types of cells Function
Connective tissue Bone
cartilage
Blood
Joins body structure together
Provides protection and support
Has the ability to store or transport
materials
13. Tissue type Types of cells Functions
Muscular tissue
Nervous system
Muscles in arms heart etc
Brain cells
Locomotion
Breathing
Peristalsis
Conduct nerve impulses
throughout the body
14. Tissues types Types of cells Function
Epidermal tissue One layer of cells
May be covered with a waxy
cuticle
Covers surface of plant
Protects from physical damage
and infection
Reduce water loss
15. Meristematic tissue Undifferentiated cells Undergoes cell division to produce
new
Vascular tissue Vascular bundle of xylem phloem
cambium
Transport water and mineral salts
Transport food
Provide support
New tissue growth in the cambium
Photosynthetic Cells with chloroplasts Cells with chlorophyll
Absorption of sunlight
photosynthesis
18. ORGANS INTHE HUMAN BODY
WHAT IS AN ORGAN?
•A structure with two or more types of
tissues that work together for a specific
function
•Your body has parts you can see, like
arms and feet, and parts you can't see,
like lungs and stomach.
•Some parts, called organs, work
independently and are separate from
others.
•Skin is one example of an organ. It's
on the outside and is the largest organ
in your body
20. MAIN ORGANS OFTHE NERVOUS SYSTEM
BRAIN
The brain is an organ that serves as the center of the nervous
system in all vertebrate and most invertebrate animals.
I PROTECT
THE BRAIN
21. LUNGS
The purposes of the lungs are to bring oxygen (abbreviated O2), into
the body and to remove carbon dioxide (abbreviated CO2).
MAIN ORGANS OF THE RESPIRATORY
SYSTEM
TRACHEA
23. HEART The human heart: vital
organ, functions as a
pump
Provides continuous
circulation of blood
through the body
Regulates body
temperature
Transports food wastes
and gases to
and from cells
MAIN ORGANS OF THE CIRCULATORY SYSTEM
26. INTESTINES
MAIN ORGANS OF THE DIGESTIVE SYSTEM
HOW LONG ARETHE
INTESTINES?
The large intestine is
1,5 metres long.
The small intestine is
6 metres long.
27. Types of organ Function
Leaf Photosynthesis
Transpiration
Flower Reproduction
28. Types of organ Function
Alimentary canal To digest food
Nose trachea lungs Gaseous exchange
Heart blood Transport oxygen and dissolved substances
29. Organ system Function
Integumentary system
(skin)
Waterproof barrier
Regulates temperature
Circulatory system Regulates body temperature
Transports food wastes and gases to
and from cells
Respiratory system Takes in oxygen
Release carbon di oxide
30. Muscular system Movements of parts of the body
Muscles found in internal organs serves to move substances in the organs
Skeletal system Supports body
Protects internal organ
Lymphatic system Filters bacteria
Digestive system Takes in and breaks down food
Absorbs nutrients
Undigested food is eliminated
31. Excretory system Removes wastes from the body
(includes lungs and skin)
Nervous system Control and co-ordinate body movements
Transmit information from the brain
Immune system Defends against infection
Endocrine system Secrete hormones
Produce response in the body
Reproductive system Produce sex cells
Protects and nourishes young during development
