11
Which organ system includes the spleen?
The lymphatic system includes the spleen.
This enzyme begins the process of carbohydrate digestion in the mouth.
In the mouth, the saliva begins to break down carbohydrates using salivary amylase. Lipase is important for the digestion of fats and this occurs in the duodenum of the small intestine. Proteases break down proteins and this process begins in the stomach. Nucleases breakdown nucleic acids, but this does not begin in the mouth.
During exhalation, the diaphragm does which of the following?
During exhalation, the air pressure in the lungs must increase greater than atmospheric pressure, to force the air out. To do this, the diaphragm must relax and lift. Inhalation involves the diaphragm contracting and lowering to allow for more volume in the lungs for air to enter. The only answer option that corresponds with the relaxing and lifting movement of the diaphragm during exhalation is answer option [A].
Electrical impulses called “action potentials” move along the axon of a neuron by _______________?
The axon is covered in myelin sheath leaving small bare intermittently spaced regions referred to as the Nodes of Ranvier. The action potential, which is an electrical signal, spreads down the axon toward the axon terminal by jumping from one node to the next. This movement is called salutatory conduction. Elongation, repolarization, and chemical messaging are not appropriate answers for this question. Therefore, the correct answer is [D].
