The physical breakdown of food into smaller pieces, which begins in the mouth with chewing.
What is mechanical digestion?
The "windpipe" that is kept open by C-shaped rings of cartilage.
What is the trachea?
These are the only arteries in the body that carry deoxygenated blood.
What are the pulmonary arteries?
These bean-shaped organs are the primary site for the filtration and removal of nitrogenous wastes.
What are the kidneys?
This type of muscle is striated, multinucleated, and under voluntary control.
What is skeletal muscle?
This leaf-shaped organ produces a "cocktail" of enzymes and bicarbonate to neutralize stomach acid.
What is the pancreas?
Inhalation occurs when air pressure inside the lungs becomes ______ than the atmospheric pressure.
What is lower?
A person with this "universal recipient" blood type has no antibodies in their plasma.
What is Type AB+?
The liver converts highly toxic ammonia into this less toxic nitrogenous waste for excretion.
What is urea?
Pairs of muscles, like the biceps and triceps, that work in opposite directions to move a joint.
What are antagonistic pairs?
This enzyme, activated by the presence of fats, breaks down triglycerides into fatty acids and glycerol.
What is lipase?
The primary physical process (movement from high to low concentration) that allows gas exchange at the alveoli.
What is diffusion?
In a blood pressure reading of 120/80, the "120" represents this phase when the heart is contracting.
What is systolic pressure?
This tube carries urine from the bladder to the outside of the body.
This tube carries urine from the bladder to the outside of the body.
This occurs when a muscle is stimulated so frequently that it cannot relax, resulting in a sustained contraction.
What is tetanus?
This section of the large intestine is primarily responsible for the reabsorption of water and the production of Vitamin K by bacteria.
What is the colon?
A respiratory condition characterized by the inflammation and narrowing of the bronchioles, often triggered by allergies.
What is asthma?
The straw-colored liquid component of blood that consists of 90% water and various proteins.
What is plasma?
The central collecting region of the kidney where urine gathers before entering the ureter.
What is the renal pelvis?
These specific muscle fibers are dark red, contain many mitochondria, and are designed for endurance.
What are slow-twitch fibers (Type I)?
These microscopic folds on the cell membranes of the villi create the "brush border" to maximize absorption.
What are microvilli?
These small, branching tubules in the lungs lack cartilage rings and serve as the final airway passages before air reaches the alveoli.
What is a bronchiole?
This specific node in the heart delays the electrical signal briefly to allow the ventricles to fill with blood.
What is the AV (Atrioventricular) node?
These cells in the hypothalamus monitor blood osmotic pressure and trigger the "thirst" sensation.
What are osmoreceptors?
This regulatory protein covers the binding sites on actin, preventing myosin from attaching during relaxation.
What is tropomyosin?
