Which blood vessels carry blood that is rich in oxygen from the lungs back to the heart?
-
Coronary arteries
-
Pulmonary arteries
-
Coronary veins
-
Pulmonary veins
Correct Answer
A. Pulmonary veinsExplanation
The pulmonary veins carry blood that is rich in oxygen from the lungs back to the heart. After oxygen is exchanged for carbon dioxide in the lungs, the oxygenated blood is transported by the pulmonary veins to the left atrium of the heart. From there, it is pumped into the left ventricle and then circulated throughout the body via the systemic circulation. The pulmonary veins are responsible for returning oxygenated blood to the heart, allowing it to be distributed to the rest of the body's tissues and organs.Rate this question:

Which muslces or muscle group is MOST important for respiration in humans?
-
Internal intercostals
-
Diaphragm
-
External intercostals
-
Transverse abdominis
Correct Answer
A. DiaphragmExplanation
The diaphragm is the main muscle responsible for respiration in humans. It is a dome-shaped muscle located at the base of the lungs, separating the chest cavity from the abdominal cavity. When we inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity and allowing the lungs to expand. This contraction of the diaphragm creates a vacuum effect, drawing air into the lungs. When we exhale, the diaphragm relaxes and moves upward, pushing air out of the lungs. Therefore, the diaphragm plays a crucial role in the process of breathing.Rate this question:

Golgi tendon organs (GTOs) can affect a static stretch by causing _________.
-
Relaxation of the muscles(s) being stretched through autogenic inhibition.
-
Contraction of the muscles(s) being stretched through autogenic inhibition.
-
Relaxation of the antagonist(s) through reciprocal inhibition
-
Contraction of the antagonist(s) through reciprocal inhibition
Correct Answer
A. Relaxation of the muscles(s) being stretched through autogenic inhibition.Explanation
Golgi tendon organs (GTOs) are sensory receptors located in the tendons that connect muscles to bones. When a muscle is stretched, the GTOs detect the increase in tension within the tendon. This information is then sent to the central nervous system, which triggers a reflex called autogenic inhibition. Autogenic inhibition causes the muscles being stretched to relax and lengthen, which helps prevent injury and allows for a greater range of motion. Therefore, the correct answer is relaxation of the muscles being stretched through autogenic inhibition.Rate this question:

What organ is PRIMARILY responsible for the digestion and absorption of nutrients?
-
Stomach
-
Pancreas
-
Small intestine
-
Large intestine
Correct Answer
A. Small intestineExplanation
The small intestine is primarily responsible for the digestion and absorption of nutrients. It is a long tube-like organ located between the stomach and the large intestine. The inner lining of the small intestine is covered with tiny finger-like projections called villi, which increase the surface area for absorption. The small intestine receives partially digested food from the stomach and continues the process of breaking down the food into smaller molecules that can be absorbed into the bloodstream. It also absorbs nutrients such as carbohydrates, proteins, fats, vitamins, and minerals, which are then transported to the cells of the body for energy and other functions.Rate this question:
