When you are HIV positive your white blood cells are constantly being attacked. Due to this, your body is not protected from any foreign invaders. People who are HIV positive can end up dying from simple bacteria/virus infection.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When a person is HIV positive, the virus attacks their white blood cells, which are responsible for fighting off infections. This weakens the immune system and leaves the body vulnerable to foreign invaders such as bacteria and viruses. As a result, even simple infections can become life-threatening for individuals with HIV. Therefore, the statement that people who are HIV positive can die from simple bacterial or viral infections is true.Rate this question:

B. Right Ventricle
E. Left Ventricle
G. Right AtriumExplanation
The four chambers of the heart are the left atrium, right ventricle, left ventricle, and right atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary vein. The blood then flows into the left ventricle, which pumps it out to the rest of the body through the aorta. On the other side of the heart, the right atrium receives deoxygenated blood from the body through the vena cava. The blood then flows into the right ventricle, which pumps it to the lungs for oxygenation.Rate this question:

Which type of gas do you release from your body during expiration? This is the gas that travels from your blood vessels to your alveoli to be expelled from your body.
Correct Answer(s)
Carbon dioxide
co2Explanation
During expiration, the body releases carbon dioxide (CO2) gas. This gas is transported from the blood vessels to the alveoli, which are small air sacs in the lungs. From the alveoli, the carbon dioxide is expelled from the body through exhalation.Rate this question:
- 17.
What type of gas provides your muscles with energy?
Correct Answer(s)
oxygen
o2Explanation
Oxygen is the gas that provides muscles with energy through the process of cellular respiration. During this process, oxygen is used to break down glucose and produce ATP, which is the main source of energy for muscle contractions. Oxygen is transported to the muscles through the bloodstream and is essential for the proper functioning and performance of muscles during physical activity. The symbol O2 represents a molecule of oxygen, consisting of two oxygen atoms bonded together.Rate this question:

What type of blood cell carries oxygen to the body in order to be used for energy in the muscle cells.
Correct Answer(s)
red blood cells
red blood cell
rbc
rbcsExplanation
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen to the body's tissues, including muscle cells. They contain a protein called hemoglobin which binds to oxygen in the lungs and transports it to other parts of the body. This oxygen is then used by the muscle cells during the process of cellular respiration to produce energy in the form of ATP. Therefore, red blood cells play a crucial role in delivering oxygen to the muscles for energy production.Rate this question:
