• The nervous system is the body system that controls and coordinates the functions of all other organ systems.
• It allowing for integration and regulation of various bodily functions.
• It consists of the brain, spinal cord, nerves, and sensory organs.

Explanation

• Bile is produced by the liver and stored in the gallbladder.
• It is released into the small intestine to facilitate fat digestion and absorption.
• Bile breaks down fats into smaller particles, making it easier for enzymes to digest them.

Explanation

This is the typical concentration in a healthy person during fasting.

The normal blood glucose level is about 80–100 mg/dL, which is roughly 0.08% of the blood by weight.

0.8% and 0.7%:

These are closer to the correct range but still slightly higher than what is typically considered normal. 

7.5%:

This is significantly higher than the normal range and would indicate a serious medical condition like diabetes.

Explanation

In humans and higher animals, the exchange of gases (oxygen and carbon dioxide) is carried out by the respiratory processes, which include:

• Breathing (inhalation and exhalation)
• Transport of gases through the blood
• Exchange of gases in the lungs (oxygen in, carbon dioxide out)

Explanation

Respiration involves two main processes:

1. Mechanical Process (Ventilation):

• Breathing in (inhalation)
• Breathing out (exhalation)
• Movement of air in and out of the lungs

2. Biochemical Process (Respiratory Exchange):

• Exchange of oxygen and carbon dioxide between the lungs and blood
• Transport of oxygen and carbon dioxide through the bloodstream
• Cellular respiration (cellular metabolism)

Explanation

We can measure our blood pressure on our own using a digital blood pressure monitor for automated readings or an instrument called a sphygmomanometer for manual readings.

A sphygmomanometer also known as a blood pressure monitor, is a device used to measure blood pressure.
