Fetal Pig Anatomy and Physiology Quiz

The larynx, also known as the voicebox, is responsible for producing sound by vibrating vocal cords when air passes through it. It is not involved in digestion, regulating blood pressure, or controlling body temperature.

The thymus is primarily responsible for the maturation of T-cell lymphocytes, which are important for the immune system response.

The correct function of the thyroid gland is to produce hormones, specifically T3 and T4, that are essential for various bodily functions, including metabolism and growth. It does not directly regulate blood sugar levels, control body temperature, or aid in digestion.

The diaphragm is a muscle located below the lungs that contracts and relaxes to help with the process of breathing by expanding and contracting the ribcage.

The lungs are responsible for the exchange of oxygen and carbon dioxide between the blood and the air in the atmosphere, essential for respiration.

The correct functions of the liver include storage of glycogen, detoxification of blood, and bile production. This organ is crucial for maintaining overall health and proper bodily functions.

The umbilical arteries carry blood away from the fetus to the placenta for exchange of nutrients and waste products. This process helps in maintaining the oxygen and nutrient supply for the developing fetus.

The gallbladder stores bile produced by the liver and releases it into the duodenum to aid in the digestion and absorption of fats.

The spleen is responsible for filtering blood and recycling iron within the body.

The stomach primarily functions in producing acid and pepsin for digestion, not absorption of nutrients, regulation of blood sugar levels, or oxygenation of the blood.

The pyloric valve specifically regulates the release of partially digested food (chyme) from the stomach to the first part of the small intestine, called the duodenum. It acts as a barrier to prevent the contents of the stomach from entering the small intestine too quickly, allowing for proper digestion and nutrient absorption.

The duodenum is the first part of the small intestine where the enzymatic breakdown of food begins after leaving the stomach.

The jejunum and ileum primarily function in absorbing digestion products from the small intestine into the bloodstream for distribution to the rest of the body.

The pancreas plays a crucial role in producing hormones like insulin and glucagon for regulating blood sugar levels, as well as digestive enzymes for breaking down food in the intestines. The incorrect answers do not accurately describe the main function of the pancreas.

The colon's main function is to reabsorb water from waste before it is eliminated from the body.

The rectum is a part of the digestive system that stores waste until it is ready to be expelled from the body through defecation.

Coronary arteries and veins specifically play a vital role in carrying blood to and from the heart muscle, ensuring it receives the necessary oxygen and nutrients for proper functioning.

The right and left atria of the heart receive blood returning from the body and pump it into the corresponding ventricles for further circulation.

The right and left ventricles of the heart are primarily responsible for pumping blood away from the heart to the rest of the body.

The adrenal gland is primarily responsible for producing hormones that help the body respond to stress and regulate water balance.

The ureter is responsible for carrying urine from the kidneys to the bladder.

The urinary bladder acts as a reservoir for storing urine until it is expelled from the body through the process of urination.

The urethra is a tube that carries urine from the bladder to the outside of the body for elimination.

The scrotum is responsible for holding the testes and maintaining the proper temperature for sperm production.

The umbilical vein carries oxygenated blood from the placenta to the developing fetus, providing essential nutrients and oxygen for the baby's growth and development during pregnancy.

The cranial and caudal vena cava are large veins that carry deoxygenated blood back to the right atrium of the heart. They do not supply blood to body tissues, carry blood to the left atrium, or connect the heart to the lungs for gas exchange.

The pulmonary trunk is a blood vessel that carries deoxygenated blood from the heart to the lungs for oxygenation.

The AORTA is the largest artery in the body and carries oxygen-rich blood from the left ventricle of the heart to the rest of the body. It does not transport oxygen from the lungs, control blood flow to the heart, or regulate blood pressure.

The kidneys are responsible for filtering waste from the blood and maintaining water balance in the body.
