What is Diaphragm?

What is Embolism?
Trace the path of oxygen-rich blood from the lungs to the body.
What is → Pulmonary veins → left atrium → mitral valve → left ventricle → aorta → body
The main function of platelets in the circulatory system.
What is Platelets (thrombocytes): Blood components that help stop bleeding by forming blood clots at sites of damaged blood vessels?
Difference between arteriosclerosis and atherosclerosis?
What is Arteriosclerosis is hardening/stiffening of arteries; atherosclerosis specifically involves fatty plaque buildup inside arteries?
Pulmonary Circulation.
What is → The respiratory system brings oxygen into the lungs and removes carbon dioxide, gas exchange happens in the alveoli. Oxygen moves from the alveoli into the blood, and the circulatory system transports it to body tissues via the ascending and descending aorta. Carbon dioxide is transported back to the lungs via pulmonary arteries to be exhaled.
A patient has prolonged bleeding after a minor injury because their blood does not clot normally.
