Answer:
vasoconstriction of capillaries.
baroreceptors in the aortic arch.
Explanation:
Vasoconstriction of capillaries and baroreceptors in the aortic arch are the two quick responses of body to maintain normal blood pressure during hemorrhage. Vasoconstriction is very necessary for lowering acute blood loss during hemorrhage means escape of blood from a ruptured blood vessel as well as maintain body heat and arterial pressure. The function of baroreceptors is to respond to the change in the tension of the arterial wall when blood pressure changes.

Controls what enters and leaves the cell
whenever one turns the pages of a book, uses a pen to take notes, or raises one's hand, one's actions are made possible by the somatic nervous system.
The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system that controls skeletal (voluntary) muscles to control body movement. It also connects the organism to its environment by receiving external stimuli through the senses of sight, hearing, taste, and smell. In contrast to the autonomic nervous system, which functions largely independently of conscious control in innervating heart muscle and exocrine and endocrine glands, the somatic nervous system uses efferent motor nerves to govern voluntary actions like walking and smiling.

The inner ear structures containing granules and helps with gravitational equilibrium are: the semicircular canals called utricle and saccule.
Ear is the organ involved in the hearing of sounds and also maintains the balance of the body. The ear is distinguished into three parts: the outer ear, the middle ear and the inner ear. The outer ear is called pinna. The middle ear consists of three most important bones called the malleus, incus and stapes.
Semicircular canals are the parts involved in balancing. These are the tiny tube like structures that contains a fluid. Apart from balancing, the semicircular canals are also able to detect the head position.
