Blood vessels that transport blood away from the heart:
- A.
Arteries
- B.
Veins
- C.
Capillaries
- D.
Nerves
Correct Answer
A. ArteriesExplanation
Arteries are the blood vessels that carry oxygenated blood away from the heart to the rest of the body. They have thick, elastic walls that help them withstand the high pressure of the blood pumped by the heart. Arteries branch out into smaller vessels called arterioles, which further divide into capillaries. Capillaries are responsible for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. After this exchange, the deoxygenated blood is then carried back to the heart through veins. Nerves, on the other hand, are not blood vessels and do not transport blood.Rate this question:

Contraction phase of the heart where both ventricles contract to pump the blood to the lungs and the rest of the body is ____________
- A.
Diastole
- B.
Systole
- C.
Pulse
- D.
Conduction
Correct Answer
B. SystoleExplanation
During the contraction phase of the heart, known as systole, both ventricles contract simultaneously to pump blood to the lungs and the rest of the body. This is an essential process that ensures proper circulation and delivery of oxygen and nutrients to all the organs and tissues. Diastole, on the other hand, refers to the relaxation phase of the heart when the ventricles fill with blood. Pulse is the rhythmic expansion and contraction of the arteries due to the heart's pumping action. Conduction refers to the electrical signals that coordinate the heart's contractions.Rate this question:

- B.
Sensory
- C.
Efferent
- D.
Vagus nerve
Correct Answer
B. SensoryExplanation
Sensory neurons are responsible for receiving information from the external environment and transmitting it to the central nervous system. These neurons are specialized to detect various stimuli such as touch, temperature, pain, and sound, and convert them into electrical signals that can be interpreted by the brain. This allows us to perceive and respond to the world around us. Motor neurons, on the other hand, carry signals from the central nervous system to the muscles and glands, enabling movement and bodily functions. Efferent neurons are a type of motor neuron that specifically transmit signals away from the central nervous system. The vagus nerve is a cranial nerve that contains both sensory and motor fibers, but its main function is to regulate the parasympathetic nervous system.Rate this question:

Movement of food in the GI tract of the human body is:
- A.
Anti-peristaltic movement
- B.
Peristaltic movement
- C.
Sliding movement
- D.
None of the above
Correct Answer
B. Peristaltic movementExplanation
Peristaltic movement refers to the coordinated contraction and relaxation of muscles in the gastrointestinal (GI) tract, which helps to propel food through the digestive system. This movement involves a wave-like motion that pushes the food forward, allowing for efficient digestion and absorption of nutrients. Anti-peristaltic movement, on the other hand, would be the reverse motion, pushing food in the opposite direction, which is not a normal physiological process in the GI tract. Sliding movement is not a recognized term in the context of GI motility. Therefore, the correct answer is peristaltic movement.Rate this question:
