This document provides an overview of several human body systems and their functions, including the digestive, reproductive, circulatory, respiratory, excretory, nervous, skeletal, muscular, and immune systems. It describes how the digestive system breaks down food, the reproductive system produces and stores gametes, the circulatory system transports substances around the body, the respiratory system supplies oxygen and removes waste, and the excretory system removes waste. It also explains that the nervous system processes information, the skeletal and muscular systems provide support and movement, and the immune system protects the body from pathogens.

Body System and 1.2 Systems

workbook next week.
4. Digestive System
• It breaks down food into molecules that
the body can use.
• Human digestive system is made up of the
digestive tract, which is a series of hollow
organs.
6. Digestive system
• Inside the hollow organs is a lining called
the mucosa.
• Mucosa – tiny glands that produce juices
to help digest food.
11. Reproductive System
• The reproductive system involves a group
of specialized organs that produces, store
and release gametes for reproduction.
• The female reproductive system has the
uterus ( womb) where babies develop
before birth.
14. Circulatory System
• The circulatory system transports
substances to and from the cells, such as
transporting oxygen, nutrients and waste
materials.
24. Nervous System
• The nervous system functions in
collecting, transferring and processing
information via cellular communication
involving nerve cells, or neurons.
26. Skeletal and Muscular Systems
• The skeletal and muscular
systems provide support and
protection by means of the bones,
and boy movements.
28. Immune System
• The immune system is the body’s defense
against infectious organisms and other
invaders. The immune system is made up
of a network of cells, tissues, and organs
that work together to protect the body.
