Classification
Nouns denoting body parts.
Examples
- The blood flows from the capillaries into the venules, which merge to form larger veins.
- A venule is a small blood vessel that collects blood from capillaries and merges with other venules to form a larger vein.
- The smallest type of venules, called postcapillary venules, receive blood directly from the capillary beds.
- Venules have thinner walls than arteries and are less muscular, which allows them to stretch and accommodate varying blood pressures.
- In the lungs, the venules receive oxygenated blood from the alveoli and transport it back to the heart through the pulmonary veins.
