Hierarchy of Structure in Animals
An undifferentiated cell that can divide to form specialized cells is called what?
What is a stem cell?
The entire length of the digestive system is lined with which type of tissue?
What is Epithelial tissue?
A thick-walled blood vessel that carries blood away from the heart
What is an artery?
True or False: When volume in the lungs increases, the pressure increases.
False.
When the volume in the lungs increases, the pressure decreases (diaphragm is low, not pushing on the lungs = inhaling)
When the volume in the lungs decreases, the pressure increases (diaphragm is up, pushing on lungs = exhaling)
What does the central nervous system consist of?
What is: the brain and spinal cord
True or False, plants are a multicellular organism
True.
A(n) _______ is a collection of similar cells that performs a particular, but limited, function
What is a Tissue?
What is the role of the digestive system?
Takes in, breaks up, and digests food and then excretes waste
What is the function of the circulatory system?
To move nutrients and gases to all of the cells of the body AND carry away wastes through the bloodstream.
Name the order in which air enters our lungs from inhale (start) to gas exchange (end)
enters nasal cavity, through pharynx, down the trachea, to the bronchi, then to the bronchioles, and then to the alveoli where gas exchange happens.
What is the main functions of the nervous system?
What is: communication and coordination of the body's activities.
What is the root system?
An example of this tissue is blood
What is Connective Tissue?
The little flap that covers the trachea so food doesn't go into the lungs is called what?
What is the epiglottis?
__________ is when the artery becomes completely blocked, either by plaque or with a blood clot.
What is a heart attack?
Name one of the 3 functions of the respiratory system
1. Provide O2 to the cells in the body
2. Remove CO2 from the body
2. Work very closely with the circulatory system
What is a neuron? AKA a nerve cell.
What do you call the tissues responsible for moving materials like water and minerals within a plant?
What are vascular tissues? (aka the vascular tissue system)
What are the 4 types of tissues an animal is made up of?
What is:
Epithelial tissue
Connective Tissue
Muscle Tissue
Nerve Tissue
I'm eating a hamburger, it's digesting in my stomach with the help of enzymes from certain organs. Which 3 organs are helping the stomach digest food?
The Liver : Bile (breaks down food)
The Pancreas: Insulin (regulates sugar in the blood)
The Gall bladder
What does ECG stand for?
What is Electrocardiogram (ECG)
The site of gas exchange is located where?
What is "between the alveoli and the capillaries surrounding it."
What does the peripheral nervous system do?
It consists of the nerves that connect the body to the CNS (central nervous system)
The shoot system is made up of the _______ the _______ and the _______
What are the leaf, flower, and stem
The only tissue that can conduct electrical signals from one part of the body to the other is called what?
What is Nerve Tissue
How do the digestive system and the circulatory system work together?
Hint: food is energy, body (muscles) need energy to function and stay alive.
The digestive system breaks down food into small molecules (nutrients).
The circulatory system provides a way to transport nutrients to all the tissues (muscle, connective, epithelial, and nerve) within the body to help it function and stay alive.
True or False The blood in veins passes through the heart BEFORE going to the lungs
True. Heart pumps deoxygenated blood towards lungs, gas exchange occurs at the capillaries, oxygenated blood goes back into the heart to get pumped into the body.
What is the part of the respiratory system between the nasal cavity and the trachea, and how do you spell it?
What is the Pharynx.
P H A R Y N X.
True or False: A Tendon is tough, elastic connective tissues that hold bones together at the joint
False. That is a ligament. (ACL)
A tendon is less elastic and connects muscle to bone (Patellar tendon)
This part of a plant is where light energy and carbon dioxide are photosynthesized into glucose (sugar) and oxygen
What is the leaf?
