Answer:
Pulmonary artery
Explanation:
The pulmonary artery delivers oxygen poor blood to the lungs that comes from the right ventricle of the heart. The pulmonary artery is also the only artery in the body that carries unoxugenated blood. When the blood goes to the lungs, it picks up oxygen and drops off carbon dioxide to be expelled from the body. The pulmonary vein then takes the oxygen-rich blood and brings it back to the heart.
A unique feature of the nucleus is that it disassembles and re-forms each time mostcells divide. At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.

Answer:
<h2>(b). two capillary beds.</h2>
Explanation:
- A human has a complete circulatory system that plays an important role in the circulation of the blood in the body of the human.
- Generally, there are two vessels that are responsible to transport the oxygenated blood and deoxygenated blood in the body.
- Generally, the artery carries oxygenated blood except for the pulmonary artery and the other is the vein that transports the deoxygenated blood except for the pulmonary vein.
- Capillaries are the microscopic vessel that is originated from the artery and connects the venules.
- When they are present in the form of a network is generally known as capillary beds and plays an important role in the exchange of nutrients, gases and other materials between the tissues cells and the blood.
- They are categorized as two capillaries bed, three capillaries bed and some other on the basis of the capillary in a network.
- Two capillary beds play an important role in the delivery of blood from the heart to the thumb and from thumb to the left ventricles.
