Match the system to the correct description
Respiratory
Circulatory
Excretory
Digestive
Endocrine
Integumentary
Reproductive
Nervous
1.
Reproductive System facilitates the continuation of a species
2.
Endocrine System
uses hormones to help regulate the body’s activities
3.
Excretory System
filters waste from blood to be expelled from the body
4.
Respiratory System
acquires oxygen for the body and releases carbon dioxide
5.
Circulatory System
dioxide
works with the above system to move oxygen to all cells and remove Carbon
6.
breaks down large molecules so they can be absorbed by the body
Digestive System
7.
Nervous System
activities
uses electrical impulses to control the body’s
8.
Integumentary System
protects from infection and helps regulate body temperature
9.
What three systems aid in body movement skeletal, muscular and nervous systems.
10.
What 2 systems work together to control and coordinate body functions:
endocrine system and nervous system.
11.
Explain what it means when we say the systems are interdependent?
It means all the body
systems depend on each other to maintain our body’s homeostasis. No system can do its job or function
properly unless ALL are doing their part / functioning properly.
12.
Where specifically does the exchange of carbon dioxide and oxygen take place in the body?The
exchange of carbon dioxide and oxygen takes place at the cell level between individual cells and the
capillaries of the circulatory system. The exchange of carbon dioxide and oxygen at the body or system
level takes place between the alveoli located in the lungs of the respiratory system and the capillaries of the
circulatory system that surround the alveoli.
Fill in the chart:
Body System
Function
Organs / main parts
Respiratory
To exchange oxygen and
carbon dioxide between the
body and atmosphere
Trachea, bronchi, alveoli, lungs,
diaphragm
Nervous
To coordinate and control the
activities of all body systems
using electrical impulses
Brain, spinal cord, nerves,senses
Endocrine
To work with nervous system
to control and coordinate
certain activities using
chemical signals called
hormones
To filter waste materials form
the blood and prepare them to
be expelled from the body
Glands (pituitary, adrenal,
pancreas) , hormones
To carry oxygen from the
lungs and nutrients form the
small intestine to all body
cells, to remove waste
products from all body cells
To allow movement of the
whole body or materials
within the body
To give the body support,
strength, and shape, protect
internal organs
To protect body from infection,
help maintain body
temperature, gather
information from external
environment
To ensure the survival of a
species, produce offspring
Heart, blood vessels (arteries,
veins, capillaries), blood
To break large food molecules
into small nutrients the body
can use
Mouth, salivary glands,
esophagus, stomach, small
intestine, large intestine, liver, gall
bladder, pancreas
Excretory
Circulatory
Muscular
Skeletal
Integumentary
Reproductive
Digestive
Kidney, ureter, unrinary bladder,
urethra
Muscles, tendons
Bones, ligaments, bone marrow
Skin, hair, nails
Ovaries, eggs
Testes, sperm
13. Explain how the digestive system, muscular system, and the circulatory system work together to supply
all cells with the nutrients they need to function properly, INCLUDE the role the villi play in this process.
The digestive system mechanically and chemically breaksdown food into small molecule that the
body can use, muscle line the digestive system organs and move the food materials through the system with
peristalsis, Once the molecules are small enough for the cells to use they are absorbed by the villi in the
small intestine and passed into the circulatory system to be transported throughout the body.
14. Explain how the respiratory system, circulatory system, integumentary system, excretory system, and
the digestive system work to remove waste from your body. The respiratory system receives carbon dioxide
gas form the circulatory system which is released form your body when you exhale. The circulatory system
picks up carbon dioxide and other waste from all cells in the body. The excretory system filters the blood in
the kidneys removing waste and forming urine which is sent to the urinary bladder to be stored until your
body expels it. The digestive system releases solid waste in the form of feces. Feces is the food materials tha
our body could not digest. Finally the integumentary releases small amounts of excess salt and other waste
with sweat.
15. Explain how the endocrine system and the reproductive system work together to ensure the survival of a
species.
The nervous system uses electrical impulses to coordinate and control the activities of the
body. The endocrine system receives direction from the nervous system then uses chemical signals called
hormones to coordinate growth and other specific activities of the body systems.
16. Explain the difference between a response and a stimulus. Explain the difference between an external
stimulus and an internal stimulus. A stimulus is a change in the environment that causes a response. A
response is the reaction / action taken due to a stimulus. An internal stimulus comes from inside your body
(hunger, thirst etc.) while and external stimulus comes from outside your body.
17. Compare and contrast sexual and asexual reproduction – include number of parents, which increases
diversity within a species, the material responsible for passing traits from parent to offspring, and whether
offspring are identical or similar to the parents Asexual reproduction = 1 parent, no combining of genetic
material therefore the offspring are identical to the parent. Sexual reproduction = 2 parents, combining of
genetic material from 2 sources therefore the offspring are similar to parents but NOT identical to the
parents. Sexual reproduction creates more variation / diversity within a species. Variation and diversity
within a species usually increases a species change of survival.
For each diagram below identify the organ, its main function, and the organ system it belongs to.
