Discuss how the nervous, circulatory, and respiratory systems interact with each other.
Liula [17]

Explanation:

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

Is the vagus nerve the heart rate centre of the brain?
koban [17]

Answer:

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.

Explanation:

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.

There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts

The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:

-Sensory: From the throat, heart, lungs, and abdomen.

-Special sensory: Provides taste sensation behind the tongue.

-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.

-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.

Of the following choices, what is the approximate LD50 of the least toxic substance? 20 mg/kg, 70 mg/kg, or 130 mg/kg
pychu [463]

The approximate LD50 of the least toxic substance will be 130 mg/Kg.

  • The dose necessary to cause the death of 50% of a population under test after a predetermined test period is known as the LD50 value for a drug.
  • Commonly used as a broad indicator of a substance's acute toxicity are LD50 values.
  • Greater toxicity is indicated by a lower LD50. A low LD50 of 500 mg/kg or less implies severe toxicity.
  • Moderate toxicity is indicated by an LD50 of 500 to 1,000 mg/kg. A modest toxicity level of 1,000 to 2,000 mg/kg is indicated.
  • The species is especially vulnerable to the poison if the LD50 is low. The lethal dose (LD50) of a specific poison might change significantly between several animal species.
  • Thus out of all the options, LD50 130 mg/kg will have the lowest toxicity and 20 mg/kg will be the highest.
