UNE BIOL 1011: Final Exam Week 13
Questions and Answers.
List the functions of the circulatory system - Answer Deliver oxygen and nutrients to the cells
Take wastes away from cells
Pulmonary Circuit - Answer Carries blood to and from the lungs
Oxygen-poor blood is pumped out of the heart's right ventricle, through pulmonary arteries, to
the lungs
As blood flows through pulmonary capillaries, it picks up oxygen and gives up carbon dioxide
Pulmonary veins return oxygen-rich blood to the heart's left atrium
Systemic Circuit - Answer The heart's left ventricle pumps blood into the aorta, which
branches into arteries and arterioles that carry blood to various body parts
Blood gives up oxygen and picks up carbon dioxide as it flows through capillaries
Oxygen-poor blood leaves the capillaries and flows through venules and veins to the heart's
right atrium
Circulates blood through the rest of the body
Identify the atria, ventricles, AV valves, semilunar valves, aorta and vena cava - Answer
Blood - Answer Blood is a specialized connective tissue that circulates through the
cardiovascular system, serving critical roles in transport, regulation, and protection.
Has a fluid extracellular matrix (plasma) and lacks fibrous components under normal conditions.
Plasma - Answer Liquid portion of the blood
Contains inorganic and organic substances dissolved or suspended in water
Help maintain blood volume
Transports dissolved substances
Maintains osmotic balance and pH
Serves as a medium for cellular exchange
Formed Elements - Answer Erythrocytes (RBCs): Transport oxygen and carbon dioxide
Leukocytes (WBCs): Immune defense and inflammation
Thrombocytes (Platelets): Blood clotting and vessel repair
