Digestive System
Respiratory System
Circulatory System
The Heart
Plants
100
This organ is where water absorption is occuring
Large intestine
100
When the diaphragm contracts and lowers, this occurs
inhalation
100
This type of blood vessel brings blood towards the heart
Vein
100
This blood vessel is the largest in the body and brings oxygenated blood from the heart towards the body
Aorta
100
This process occurs in the shoot system
Photosynthesis
200
Mechanical digestion occurs in the mouth through these (hint: 2 components)
The teeth and tongue
200
These structures in the lungs are where gas exchange occurs, bringing O2 into the blood and CO2 out of the blood
Alveoli
200
Fish have this kind of circulatory system
Single-Loop
200
The pulmonary artery brings this kind of blood from the heart to the lungs
deoxygenated
200
This type of tissue transports water throughout a plant
Xylem
300
These structures, found in the small intestines, absorb nutrients into the bloodstream
Villi / microvilli
300
oxygen that is provided to the cells is used by this organelle to undergo cellular respiration
Mitochondria
300
These arteries supply the heart with blood
Coronary arteries
300
This heart chamber receives blood from the body
Right atrium
300
Carrots are this type of root
Taproot
400
The flap closes over the trachea to allow the food to enter the esophagus
Epiglottis
400
The trachea differs from the esophagus because it needs to remain open. These C-shaped structures keep the trachea from collapsing.
Cartilage rings
400
These structures in the circulatory system work against gravity to prevent backflow as the blood travels back towards the heart
valves
400
When the heart is relaxed it is in this phase of the cardiac cycle
Diastole
400
These cells can produce a waxy waterproof cuticle
Epidermis cell
500
These structures control the flow of food, digested food, and waste through the system
Sphincters
500
This disease causes the constriction of bronchioles and excess mucus production. It can be triggered by allergens, stress, and even cold temperatures.
Asthma
500
Plaque buildup within the arteries can cause narrowing which is known as this
Atherosclerosis
500
The lub-dub sound of the heart is caused by the closing of these
heart valves
500
These types of tissue are undifferentiated and can become specialized tissues
Meristematic cells
