How the body is organized Flashcards
Cell-
The smallest structural & functional unit of an organism
Tissue-
Group of similar cells that perform the same function
Organ-
A structure composed of different kinds of tissue. Perform a specific & complex job.
Organ System-
Group of organs that work together to perform a major function
Give examples of cells:
Blood cells, nerve cells, muscle cells, etc.
Give examples of tissues:
Connective tissue, muscle tissue, nervous tissue, epithelial tissue.
Give examples of Organs:
Brain, liver, skin, bones, stomach, heart
List some Organ systems:
Muscular, skeletal, circulatory, digestive, nervous, etc
What is the order of levels of organization in the human body from simplest to most complex
Cell, tissues, organ, organ systems, organism
What is the special way we remember the names of the 11 organ systems?
Dr. IE MCSNIRE
Which body system is responsible for helping organisms to make copies of themselves?
Reproductive
The lungs, mouth, throat, and nose are all a part of which system?
respiratory
Which body system defends against disease?
immune
Which body system protects the body, helps keep water inside and regulates body temperature?
integumentary (skin)
Which two body systems work together to bring oxygen to the cells?
Respiratory & circulatory
Which body system is responsible for working with the bones to allow for movement?
Muscular System
Which system helps to take in food, break it down?
Digestive
Which system helps to remove waste?
Excretory
Which system supports the body, protects it, and works with muscles to allow movement?
Skeletal
Which body system controls many body processes with chemicals/hormones such as the intake of sugar by cells?
Encrodine
List the names of each system
Digestive, respiratory, immune, endocrine, muscular, circulatory, skeletal, nervous, integumentary, reproductive, excretory
Describe how two systems of the body work together to bring oxygen to the cells.
Respiratory brings the oxygen in your body through your lungs when you breathe- which gets passed to our heart. The circulatory system helps to circulate or pass around oxygenated blood throughout your body.
Describe how two systems of the body work together to eliminate waste (excess salts, & water) from the body.
The blood vessels of the circulatory system pass through the kidneys. The kidneys are part of the excretory systems whose function is to clean the blood of excess salts, minerals, and water. It passes out of the body in the form of urine.
Describe how two systems of the body work together to bring nutrients(food) to the cells.
Digestive and circulatory:
Food and water are absorbed by the intestines through the villi and passed to the blood through the capillaries and then circulated throughout the body by the circulatory system.
Describe how two systems of the body respond to stimuli (anything that your 5 senses can detect).
Nervous & endocrine system- The nervous system relays information back to the brain to help the body maintain stable internal conditions.
The brain regulates hormones, through the endocrine system that tells the cells of the body to reproduce by making a copy of the cell.
