ANATOMY

1
ANATOMY

• OVERVIEW OF THE HUMAN BODY

2
WHAT IS ..?

• ANATOMY is the study of the form and structure of
  the human body.
• PHYSIOLOGY is the study of the function or how
  the body works.

3
BASIC SUBSTANCE OF LIFE

• Protoplasm makes up all living matter.
• Protoplasm contains carbon, oxygen, hydrogen,
  nitrogen and other minerals.

 

4
CELLS

• Cells are the basic units or building blocks of
  all living things.
• Cells are made up of protoplasm.
• Cells carry on all functions of life.

5
CELLS

• Cells use food and oxygen eliminate waste, adapt
  to environment and reproduce.
• Cells may be different size and shapes.

6
Cells

• Some groups of cells may be highly specialized
  e.g. nerve cells are quick to be respond to
  stimuli, red blood cells carry oxygen.
• Some specialized cells lose some function,
  certain nerve cells do not reproduce.
• An interdependency exists among cells to carry on
  total life activities.

7
PARTS OF CELLS

• Cell membrane outer covering of cell
• Cytoplasm main substance of the cell, it is
  liquid.
• Nucleus brain of the cell.
• The nucleus contains the chromatin network and
  nucleolus.

8
PARTS OF CELLS

• The nucleolus is one or more tiny parts within
  the nucleus.
• The chromatin network is made up of chromosomes
  which contain the heredity genes, known as DNA.

9
TISSUES

• Cells group together by their shape, size,
  structure, and function, and are called tissues.
• This specialized grouping of cells make four
  different types of tissues.

Skin structure

TYPES OF TISSUE

• Epithelial tissue covers surfaces and lines body
  cavities, also forms glands.
• Connective tissue holds parts of the body
  together. It may be hard as in bone, or soft as
  in vascular tissue (Blood vessels)
• Both types repair easily.

11
TISSUE TYPES

• Nerve tissue conducts nerve impulses, and reacts
  to stimuli.
• Some nerve tissue does not repair, all is slow
  and uncertain.

12
TISSUE TYPES

• Muscle tissue produces power by contractions
  There are three types of muscle tissue.
• Cardiac, located in the heart
• Skeletal muscles, also called voluntary
• Smooth muscles, called involuntary such as
  digestive tract and kidney.
• Repairs with difficulty resulting in scar tissue.

13
ORGANS

• Tissues which form together and perform special
  functions are called organs.
• Example Stomach and the skin which contain
  epithelial, connective, muscle and nervous tissue.

14
Systems

• A group of organs working together to perform a
  specific function are called systems.
• The digestive system is made up of several
  organs mouth, stomach, intestines.
• The circulatory system contains the heart, blood
  vessels.
