This node is known as the heart’s natural pacemaker.


SA node 

300

The four characteristics of muscle cells include excitability, contractability, extensibility, and this.


Elasticity


300

This pregnancy change results in increased oxygen demand


Ventilation increases


400

A substance that releases hydrogen ions in water is known as this

Acid 

400

The little brain responsible for balance and coordination.

Cerebellum 

400

These arteries are the only ones that carry deoxygenated blood.

Pulmonary arteries


400

This muscle type is found in the digestive tract and blood vessels


Smooth muscle

Blood volume increases by this percentage during pregnancy


30–50%


500

Bases balance acids by doing this with hydrogen ions
