Question

2) In organ of human beings which excretes water and salt by evaporation.
3) A process by which kidneys regulate the water content of the body.
4) Bundles of neuron fibres.
5) The structure which receives stimuli.​

Answer 1

Answer:2) The body loses water primarily by excreting it in urine from the kidneys. Depending on the body's needs, the kidneys may excrete less than a pint or up to several gallons (about half a liter to over 10 liters) of urine a day.

3) The kidneys can adjust the concentration of the urine to reflect the body's water needs, conserving water if the body is dehydrated or making urine more dilute to expel excess water when necessary. ADH is a hormone that helps the body to retain water by increasing water reabsorption by the kidneys.

4) Each bundle of nerve fibers is called a fasciculus and is surrounded by a layer of connective tissue called the perineurium. Within the fasciculus, each individual nerve fiber, with its myelin and neurilemma, is surrounded by connective tissue called the endoneurium.

5) When a stimulus is received by a sensory neuron, the impulse (or message) is carried through fibrous extensions called dendrites to the cell body. The cell body is made up of cytoplasm, cytoplasmic structures, and a nucleus, which controls neuron function.
