Transcript Animal Organ Systems

Animal Organ Systems
• Anatomy and Physiology
Fundamentals of Life
 All
living things are made up of cells.
 Cells are the most basic structure of life.
 Cells need oxygen, food/energy, and
water to survive.
Natural Hierarchy
 Cells
are the most basic and simple.
 Cells that are all alike work together to form
tissues which perform tasks.
 Tissues that are alike work together to form
organs which complete jobs.
 Organs work together in organ systems to
carry out processes.
 Organ systems work together to support the life
of an organism.
How do we study animals?
look at the outside of them – the
outer physical structures.
 We look inside of dead animals – the
internal physical structures.
 We look at the tissues under a
microscope – microscopic structures.
 We study the chemical reactions
between cells, tissues, and organs.
 We
Anatomy
 The
study of the form, shape, and
appearance of an animal – its structures
both internal and external.
 Gross
anatomy is the study of the
structures – internal and external – that we
can see with the naked eye.
 Microscopic anatomy is the structures that
can only be seen under magnification
Physiology
 The
study of the functions of the cells,
tissues, and organs of the animal.
 Biochemistry
 How cells, tissues and organs work
together to complete a task…digestion.

 Heart
 Technically
a muscle
 Pumps blood with 4 chambers and 2 valves
 Arteries
 Carry
oxygen rich blood from lungs and heart
to tissues
 Veins
