Cardiovascular system Flashcards
What is the role of the CS
To move blood throughout the body to supply nutrients and oxygen and get rid of waste and Carbon dioxide.
What is the function of the systemic circulation?
Systemic circulation moves oxygenated blood from the heart to the body to supply nutrients and oxygen, and removes waste and carbon dioxide.
What is the role of the pulmonary circulation?
Pulmonary circulation moves blood from the heart to the lungs for oxygenation and to remove carbon dioxide, then returns the oxygenated blood to the heart.
What is the main artery that carries blood from the left ventricle to the body?
The aorta carries oxygenated blood from the left ventricle to the body, supplying the head, arms, organs, and legs.
Where does the abdominal aorta split, and what does it supply?
The abdominal aorta splits into two branches that supply the pelvic structures and the legs.
What are the two main veins that return blood to the heart, and where do they drain?
The superior vena cava (from the head, neck, and upper limbs) and the inferior vena cava (from the legs, pelvis, and abdomen) drain into the right atrium of the heart.
How does blood flow through the heart after returning from the body?
Blood flows from the right atrium to the right ventricle, then to the lungs via the pulmonary arteries. After oxygenation, it returns to the left atrium, then to the left ventricle, and is pumped out to the body.
Why is the cardiovascular system important for pharmacists?
The cardiovascular system is key for drug delivery via the bloodstream and is associated with common conditions like hypertension, atherosclerosis, and angina that require pharmacological treatment.
