Gas exchange in the lungs occurs across this membrane by rapid diffusion

What is the respiratory membrane?

100

Process uses hydrochloric acid & enzymes like pepsin, trypsin, chymotrypsin & carboxypeptidase to break proteins into smaller chains of amino acids.

What is protein digestion?

100

This plasma protein is converted into active fibrin by thrombin during the major event of blood clot formation.

What is fibrinogen?

100

Kidneys rely on these tiny filtering units to remove wastes and extra substances from the blood.


What are nephrons?

100

This blood type is known as universal donor; it can be given to nobody of the ABO blood group

What is O negative?

200
This group of neurons in the medullary rhythmicity center stimulates the respiratory muscles during breathing

What is the ventral respiratory group?

200

Organ stores bile & releases it into the duodenum through contraction of its muscular wall, but can sometimes develop cholesterol gallstones that require surgical removal.

What is the gallbladder?

200

This structure forms when platelets stick together at the site of a damaged blood vessel, helping stop bleeding especially in small vessels

What is a platelet plug?

200

Pair of organs regulates water balance, blood pressure using renin, red blood cell production through EPO, electrolyte levels, and the body's pH

What are the kidneys?

200

This respiratory function brings air into the lungs during breathing

What is inhalation?

300

These tiny grape like air sacs in the lungs are surrounded by capillaries and the are the main site where oxygen enters the blood and carbon dioxide leaves the body 

What are alveoli?

300

People who are lactose intolerant lack enough of this enzyme needed to break down the sugar lactose in the small intestine

What is lactase? 
300

After a blood vessel is injured this is the first of three processes the body may use to slow or prevent blood loss

What is vascular spasm?

300

This organ performs deamination of amino acids, converting toxic ammonia into urea before its excreted by the urinary system

What is the liver?

300

This function of the circulatory system prevents excessive blood loss after a vessel is damaged

What is hemostasis?

400

This brainstem region contains the ventral respiratory group that stimulates the muscles responsible for breathing

What is the medulla oblongata?

400

This hormone released by cells in the stomach & the duodenum stimulates the stomach to increase gastric secretions during digestion.

What is gastrin?

400

This process involves platelets, clotting factors and fibrin formation to prevent blood loss after vessel injury

What is blood coagulation?

400

This group of cells located at the end of the ascending limb of the nephron loop sense low levels of sodium, potassium or chloride and helps trigger renin release.

What are macula densa cells?

400

This kidney function is triggered by low Na+, K+ or CL- & helps raise blood pressure

What is renin release ( blood pressure regulation)?

500

This condition involves rapid deep breathing that lowers blood CO2 levels and can temporarily breath holding time

What is hyperventilation?

500

This hormone is released by the duodenum when acidic chyme enters it & stimulated the pancreas to secrete bicarbonate to neutralize stomach acid

What is secretin?

500

This liver produced protein is the inactive precursor that is converted into thrombin during blood clotting

What is prothrombin?

500

This plasma protein is converted by renin to begin the process that ultimately produces angiotensin, helping regulate blood pressure.

What is angiotensinogen?

500

This digestive function uses bile & lipases to break down fats for absorption into the lymphatic system

What is fat digestion?
