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