Why are nephrons surrounded by many tiny blood vessels
The blood vessels and the heart are lined by the endothelium! The heart is also lined by the epicardium, and is surrounded by the pericardial sac.
No, most blood vessels are innervated by both sympathetic and parasympathetic nerve fibers. However, sympathetic nerve fibers typically have a more pronounced effect on blood vessel activity compared to parasympathetic fibers.
The part of a tooth where the nerve and blood vessels are found is called the pulp chamber.
The dermis, or lower layer of the skin, contains blood vessels and sensory nerve endings

Blood vessels and nerves that supply nutrients to the bone cells within the osteon (Haversian system).
Neuron or nerve. Either will fit.
The pulp in teeth is the part which is taken out when you have "root canal therapy", it is the nerve and blood vessels. The pulp in teeth is the part which is taken out when you have "root canal therapy", it is the nerve and blood vessels.
Blood vessels are surrounded by smooth muscle. This is often known as visceral muscle. This type of muscle also lines the blood vessels and internal organs.
The dermis.
Yes, the dermis is rich in blood vessels (when you itch or scratch your skin and it turns red) and the dermis is rich in nerve fibers because of when you touch your skin you can feel it. TRUE
