Maintaining homeostasis science

Living things carry out

Nutrition, transport, excretion, respiration, and regulation

The life function of nutrition is carried out by

The digestive system

The digestive system

Breaks down food to create energy for life functions

Autotrophic

Organisms make their food on their own examples our plants.

Heterotrophs

They cannot make their food on their own

Nutrition

It’s when organisms convert in organic and organic foods into smaller pieces that can be transported by blood

The life function transport is carried out by

The circulatory system

The circulatory system

Movement of materials within an organism includes the heart blood and blood vessels

Trans Pork.

Movement of materials, also known as circulation absorption, and takes in nutrients

The life function excretion

Is carried out by the excretory system

Excretory system is

removal of waste think X exit

Excretion

Removal of waste, the release of cellular waste

The life function Respiration is carried out by

The respiratory system

Respiratory system

It’s where the energy in food gets converted to ATP the form of energy which can be used by cells

Respiration

It is not breathing

The process that converts energy from food into ATP it’s the release of energy by an exchange of gases

Anaerobic

Organisms do not need oxygen

Aerobic

Organisms need oxygen for respiration

Life function regulation, carried out by

The nervous and endocrine system

Regulation

the process in which you respond to external and internal stimulate to maintain homeostasis

Nervous system

Control with electrical messages delivered by nerve cells

Endocrine system

Hormones are chemical messages that direct activities in other organs

Nervous and endocrine system

The control of various activities of an organism
