Digestive system
This flap of cartilage covers the opening of the larynx during swallowing.
This is the primary site of gas exchange in the lungs.
This thyroid hormone plays a crucial role in regulating metabolism.
These are the smallest veins that collect blood from capillaries
What are venules?
This muscular sac stores urine.
These enzymes, secreted by the pancreas, are crucial for the digestion of proteins in the small intestine.
What are trypsin and chymotrypsin?
The volume of air inhaled or exhaled during a normal breath is known as this.
What is tidal volume?
This mechanism, where the product of a pathway inhibits an earlier step in the pathway, is common in endocrine regulation.
What is negative feedback?
This is the layer lining the inside of the heart chambers
The presence of glucose in the urine, known as glucosuria, often indicates this condition.
This section of the small intestine is primarily responsible for the absorption of vitamin B12 and bile salts.
These structures in the nasal cavity help to warm, humidify, and filter inhaled air.
What are the nasal conchae (or turbinates)?
Produced by the adrenal cortex, this hormone regulates sodium and potassium balance.
What is aldosterone?
This is the period of ventricular relaxation and filling.
This nitrogenous waste product is the primary end product of protein metabolism and is excreted in urine.
What is urea?
These lymphatic capillaries within the villi of the small intestine absorb digested fats.
What are lacteals?
The maximum volume of air that can be exhaled after a maximal inhalation is known as this.
What is vital capacity?
These chemical messengers exert their effects on target cells by binding to specific receptors.
Heart rate is primarily regulated by this division of the autonomic nervous system.
What is the parasympathetic nervous system (via the vagus nerve)?
This part of the nephron is primarily responsible for the reabsorption of glucose and amino acids.
These structures at / around the oral cavity help in chemical part of digestion
what are salivary glands ?
This law states that the total pressure exerted by a mixture of gases is the sum of the partial pressures of the individual gases.
What is Dalton's Law of Partial Pressures?
This hormone, released by the posterior pituitary gland, stimulates uterine contractions during childbirth.
What is oxytocin?
This specialized tissue in the right atrium initiates the electrical impulses that drive the heart rate.
This hormone, produced by the adrenal cortex, increases sodium reabsorption in the distal tubule and collecting duct.
