Circulatory System
major organ of the circulatory system
Heart?
What is also known as the windpipe
Trachea
What starts the chemical reactions when breaking down food
Salivary glands and chewing
What is an advantage of sexual reproduction
Genetically diverse offspring, adaptability
Which system has the esophagus, stomach and intestines
Digestive system
best describes a function of the circulatory system
To circulate blood?
Where does the exchange of oxygen and carbon dioxide happen
The alveoli (lungs)
Where is food mixed with acid to break it down
Stomach
What is an advantage of asexual reproduction
What body system processes foods into a useable source of energy
Digestive system
What are the functions of valves?
The valves prevent the backward flow of blood
What is the reason the respiratory system is important
It controls breathing and gas exchange in the body
What are the two parts of the digestive system where the process begins
Mouth and teeth
Not energy efficient, takes a long time, fewer offspring, requires two parents
What system has lungs, trachea, bronchi and alveoli
Respiratory system
What type of vessel carries the blood away from the heart?
Aorta
The respiratory system is controlled by involuntary muscle movement from here
The diaphragm
What is the purpose of the digestive system
Breaks down food to release nutrients needed for energy production
What is a disadvantage of asexual reproduction?
Lack of genetic diversity, high risk of disease, limited adaptation
Compare the respiratory system to the circulatory system
The respiratory system provides oxygen for cells, while the circulatory system transports oxygen to cells
What type of vessel carries the blood towards the heart?
What role does the nose play in the respiratory system?
It inhales air, and has hairs to help filter out dust
What is the purpose of the vili and microvili?
They create a larger surface area in order to absorb more nutrients
What is something that occurs in both asexual and sexual reproduction?
Produce offspring, pass on genetics, contribute to species survival, influenced by the environment
What system has veins, arteries, heart, blood vessels
Circulatory system
