B. Blood vesselsExplanation
Involuntary or smooth muscles are found in the blood vessels. These muscles are not under conscious control and are responsible for controlling the diameter of blood vessels, which regulates blood flow and blood pressure. They help in the process of vasodilation (widening of blood vessels) and vasoconstriction (narrowing of blood vessels) to maintain proper blood flow throughout the body.

- A.
Pharynx.
- B.
Epiglottis.
- C.
Larynx.
- D.
Bronchi
Correct Answer
B. Epiglottis.Explanation
The epiglottis is a leaf-shaped valve that prevents food from entering the trachea. It is located at the base of the tongue and covers the opening of the trachea during swallowing, ensuring that food goes down the esophagus and into the stomach instead of entering the respiratory system. This mechanism prevents choking and allows for the smooth passage of food and air.

A. LarynxExplanation
The larynx is the structure that contains the voice box. It is located in the throat and is responsible for producing sound by vibrating the vocal cords. The larynx also plays a role in protecting the airway during swallowing and preventing food and liquids from entering the lungs. The pharynx is the passage that connects the nasal and oral cavities to the esophagus and trachea. The trachea, also known as the windpipe, is a tube that carries air to and from the lungs.

- D.
All of the above.
Correct Answer
C. AII structures are smaller and more easily obstructed.Explanation
Pediatric airways differ from adult airways in multiple ways. One difference is that all structures in a child's airway are smaller compared to an adult's airway. This includes the size of the tongue, trachea, and other structures. Additionally, due to their smaller size, pediatric airways are more easily obstructed, making it more challenging for air to flow freely. Therefore, the correct answer is that all structures in pediatric airways are smaller and more easily obstructed.Rate this question:

The major artery in the thigh is called the femoral artery. This artery is responsible for supplying blood to the lower extremities. It is one of the largest arteries in the body and is located in the groin area. The femoral artery carries oxygenated blood from the heart to the thigh and then branches out to supply blood to the rest of the leg.Rate this question:

The vessel that carries oxygen-poor blood to the right atrium is the:
- A.
Posterior tibia.
- B.
Internal jugular
- C.
Vena cava.
- D.
Aorta.
Correct Answer
C. Vena cava.Explanation
The vena cava is the correct answer because it is the largest vein in the body and carries deoxygenated blood from the body back to the heart. The posterior tibia is a bone in the lower leg and is not involved in carrying blood. The internal jugular is a vein in the neck, but it carries blood from the head and neck to the heart. The aorta is the largest artery in the body and carries oxygenated blood from the heart to the rest of the body.Rate this question:

The fluid that carries blood cells and nutrients is:
- A.
Platelets,
- B.
Hemoglobin.
- C.
Lymph.
- D.
Plasma.
Correct Answer
D. Plasma.Explanation
Plasma is the correct answer because it is the fluid component of blood that carries blood cells and nutrients throughout the body. It makes up about 55% of the total blood volume and contains various substances such as water, electrolytes, proteins, hormones, and waste products. Platelets are cell fragments involved in blood clotting, hemoglobin is a protein in red blood cells that carries oxygen, and lymph is a clear fluid that circulates in the lymphatic system.Rate this question:

The blood component that is essential for the formation of blood clots is called:
- A.
Plasma,
- B.
Platelets.
- C.
Vvhite blood cells.
- D.
Red blood cells.
Correct Answer
B. Platelets.Explanation
Platelets are the blood component that is essential for the formation of blood clots. When there is an injury or damage to a blood vessel, platelets are activated and form a plug at the site of injury, preventing excessive bleeding. They also release chemicals that help in the formation of a fibrin mesh, which further strengthens the clot. Without platelets, blood clotting would be impaired, leading to prolonged bleeding and difficulty in wound healing.Rate this question:

The pressure on the walls of the artery when the left ventricle contracts is the _______ pressure.
- A.
Systolic
- B.
Arterial
- C.
Diastolic
- D.
Residual

The nervous system is subdivided into:
- A.
Central and peripheral systems.
- B.
Bones and muscles.
- C.
Brain and skin.
- D.
Spine and vertebral column.
Correct Answer
A. Central and peripHeral systems.Explanation
The correct answer is central and peripheral systems. The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes all the nerves that extend from the CNS to the rest of the body. This division allows for the coordination and communication between the brain and the rest of the body, allowing for the control of bodily functions and responses to stimuli.Rate this question:
