Weegy: What about human body? Please clarify your question. Thank you. User: Pulmonary circulation transports oxygen-poor blood from the right ventricle to the ________, where blood picks up a new blood supply. Weegy: lungs User: The various activities of the nervous system include a function such as, ________. Weegy: The nervous system is the body’s main control system. It is made up of the CENTRAL NERVOUS SYSTEM (or CNS) and a network of NERVES that extend from the CNS to all parts of the body. [ The nervous system regulates both voluntary activities, such as walking and talking, and involuntary activities, such as breathing, which you make no conscious decisions about. PARTS OF THE SYSTEM The CNS consists of the brain and spinal cord. The rest of the nervous system, called the peripheral nervous system, consists of nerves. These include 12 pairs of nerves that branch from the brain (cranial nerves) and 31 pairs that branch from the spinal cord (spinal nerves). NEURONS The nervous system contains billions of neurons (nerve cells). A neuron has a cell body, arms called dendrites, and a long projecting fibre, the axon. Electrical signals – up to 2,500 per second – can pass along axons. They can also jump between neurons by means of chemicals that pass across the gaps in synapses (neuron junctions). PARTS OF THE BRAIN The main parts of the brain are the large folded cerebrum, the brainstem, which forms a stalk at the foot of the brain, the cerebellum behind it, and central structures, such as the thalamus. NERVES Nerves are made up of bundles of the axons of nerve cells. Some of these carry information picked up by sensory receptors around the body to the CNS for processing. Other axons carry messages from the CNS to muscles, causing movement, or to the body’s glands, causing the release of hormones. Many axons are surrounded by a protective sheath containing a fatty substance called myelin. This acts to insulate the axons electrically. NERVE ... (More)
