Слайд 2Human Body Systems
Section 35–1
This section describes human organ systems and explains
how the body maintains homeostasis.
Слайд 3Organization of the Body

in the human body
The four types of tissues are
muscle tissue,
epithelial tissue,
connective tissue,
nervous tissue
The four types of tissues are
muscle tissue,
epithelial tissue,
connective tissue,
nervous tissue
Слайд 7Organization of the Body
Circle the letter of the type
of tissue that covers interior and exterior body surfaces.
epithelial
epithelial
Слайд 8Organization of the Body
What is a gland?
A gland is a structure
that makes and secretes a particular product such as saliva, sweat, or milk.
Слайд 9Organization of the Body

Слайд 10Maintaining Homeostasis
The process of maintaining a controlled, stable internal environment
is called
homeostasis
homeostasis
Слайд 11Maintaining Homeostasis
The process in which a stimulus produces a response that
opposes the original stimulus is referred to as________.
feedback inhibition
feedback inhibition
Слайд 12Maintaining Homeostasis
Fill in the missing labels in the diagram to show
how a thermostat uses feedback inhibition to maintain a stable temperature in a house.
Слайд 13Maintaining Homeostasis
Is the following sentence true or false?
The part of
the brain that monitors and controls body temperature is the hypothalamus.
true
true
Слайд 14Maintaining Homeostasis
What happens if nerve cells sense that the core body
temperature has dropped below 37°C?
The hypothalamus produces chemicals that signal cells throughout the body to speed up their activities, which causes a gradual rise in body temperature.
The hypothalamus produces chemicals that signal cells throughout the body to speed up their activities, which causes a gradual rise in body temperature.
Слайд 15Maintaining Homeostasis
What happens if the body temperature rises too far
above 37°C?
The hypothalamus slows down cellular activities, minimizing the production of heat.
The hypothalamus slows down cellular activities, minimizing the production of heat.
