The pancreas is an accessory organ and is not part of the digestive tract itself.

The bronchi are part of the lower respiratory tract, while the nasal cavity, pharynx, and larynx are part of the upper respiratory tract.

Alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.

The placenta is responsible for the exchange of nutrients and waste between the mother and fetus.

The liver plays a crucial role in detoxifying chemicals and metabolizing drugs.

The kidneys are primarily responsible for filtering blood and removing waste products from the body.

The liver produces bile, which is stored in the gallbladder and released into the small intestine to help digest fats.

The cerebellum is responsible for coordinating voluntary movements and maintaining balance.

The medulla oblongata controls autonomic functions, including the regulation of breathing patterns.

The medulla oblongata is responsible for regulating the rate and depth of breathing based on the body's needs.

The medulla oblongata is the part of the brain that regulates the respiratory rate by responding to carbon dioxide levels in the blood.

The large intestine is primarily responsible for the absorption of water from indigestible food matter.

The right ventricle pumps deoxygenated blood to the lungs for oxygenation.

The left ventricle is responsible for pumping oxygenated blood to the body.

The large intestine is primarily responsible for the absorption of water from indigestible food matter.

The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs.

The follicular phase is characterized by the thickening of the endometrium in preparation for potential implantation.

The luteal phase is characterized by the thickening of the uterine lining in preparation for potential implantation.

Viviparity is the reproductive strategy where offspring develop inside the mother's body and are born live.

Asthma is characterized by chronic inflammation of the airways, leading to difficulty in breathing.

Bronchitis is characterized by inflammation of the bronchial tubes, leading to coughing and difficulty breathing.

Bronchitis is the inflammation of the bronchial tubes, leading to coughing and difficulty breathing.

Lung cancer is primarily caused by smoking, which introduces carcinogens that can lead to the development of cancerous cells in lung tissue.

The umbilical cord connects the fetus to the placenta, facilitating nutrient and waste exchange.

The ectoderm gives rise to the skin and nervous system during embryonic development.

The sinoatrial (SA) node initiates the electrical impulse that triggers heart contractions.

The pancreas is responsible for producing insulin, a hormone that regulates blood sugar levels.

The lens is responsible for focusing light onto the retina, allowing for clear vision.
