Heart Anatomy
The valve located between the left atrium and left ventricle.
What is the mitral (bicuspid) valve?
Vessels that carry blood away from the heart.
What are arteries?
Primary function of red blood cells?
What is oxygen transport?
Name two organ systems directly involved in oxygen delivery.
What are the respiratory and cardiovascular systems?
This gland is considered the “master gland”?
What is the pituitary gland?
Heart chamber has the thickest myocardium?
What is the left ventricle?
This blood vessel is the primary site of exchange?
What are capillaries?
Which plasma protein is most important for maintaining osmotic pressure?
What is albumin?
Which organ system works most closely with the cardiovascular system to regulate pH?
What is the respiratory system?
This hormone lowers blood glucose levels?
What is insulin?
The vessel that carries deoxygenated blood from the heart to the lungs.
What is the pulmonary artery?
Why do veins contain valves?
What is to prevent backflow of blood toward the heart?
Main role of the lymphatic system?
What is returning excess interstitial fluid to the bloodstream and supporting immune function?
How do the nervous and endocrine systems differ in signal transmission speed?
What is:
Nervous signaling is rapid and short-term; endocrine signaling is slower and long-lasting.
This gland regulates metabolic rate?
What is the thyroid gland?
Structure that prevents back flow into the right atrium during ventricular contraction?
What is the tricuspid valve?
Which vessel type experiences the greatest resistance to blood flow?
What are arterioles?
Where are lymphocytes primarily produced or matured?
What is:
Bone marrow (production) and thymus (T-cell maturation)
Which system is primarily responsible for long-term regulation of blood pressure?
What is the renal (urinary) system?
What hormones are released during the stress response?
What is Cortisol
Identify the correct sequence of blood flow starting from the superior vena cava.
What is:
Superior vena cava → Right atrium → Tricuspid valve → Right ventricle → Pulmonary valve → Pulmonary artery → Lungs → Pulmonary veins → Left atrium → Mitral (bicuspid) valve → Left ventricle → Aortic valve → Aorta
How does vessel diameter influence blood pressure and flow?
What is:
As vessel diameter decreases, resistance increases, raising blood pressure and reducing flow.
Explain how the lymphatic system supports cardiovascular function.
What is:
The lymphatic system returns fluid to circulation, prevents edema, and supports immune defense.
Describe how at least three organ systems work together during physical exercise.
What is:
Muscular (movement), cardiovascular (oxygen delivery), respiratory (gas exchange), and nervous system (coordination).
Explain the difference between endocrine and exocrine signaling.
What is:
Endocrine signaling releases hormones into the bloodstream, while exocrine signaling uses ducts to target specific locations.
