    Study Notes

    Cerebrovascular Disease

    • Cerebrovascular disease is a condition that affects the blood vessels in the brain, leading to a blockage or aneurysm.
    • Aneurysms can cause a more deadly hemorrhagic, or bleeding, stroke.

    Heart Attack

    • A heart attack occurs when the coronary artery is blocked, usually by a blood clot formed on a ruptured plaque in the artery.
    • The blockage deprives the heart muscle of oxygen and nutrients, leading to damage or death of the heart tissue.
    • Symptoms include chest pain, shortness of breath, and potential life-threatening consequences.

    Arrhythmias

    • Arrhythmias are abnormal heart rhythms due to irregular electrical impulses in the heart that can lead to palpitations, dizziness, or fainting.
    • Causes include aging, heart attacks, or other heart conditions.

    Cardiomyopathy

    • Cardiomyopathy is impaired heart function due to the weakening or thickening of the heart muscle.
    • Causes include genetics, infections, and certain drugs.
    • May lead to heart failure.

    Congenital Heart Defects

    • Structural abnormalities present at birth, often due to genetics or maternal exposure to certain substances during pregnancy.
    • Altered blood flow through the heart, leading to a range of symptoms.

    Pulmonary Arteries

    • The pulmonary arteries deliver oxygen-poor blood from the heart to the lungs.
    • The arteries are shaped like tubes with an opening called a lumen.

    Renal Arteries

    • The right renal artery originates from the anterolateral aspect of the aorta and runs to the right kidney.
    • The left renal artery originates from the lateral aspect of the aorta and runs to the left kidney.
    • The renal arteries supply the kidney parenchyma with oxygenated blood.

    Types of Arteries

    • Arteries are blood vessels that carry oxygenated blood away from the heart.
    • Aorta: The largest human artery, originating from the left ventricle.
    • Arterioles: Small blood vessels that branch out from arteries.

    Neutrophils

    • Neutrophils, a type of white blood cell, contain up to 5 nuclear lobes.
    • They are critical for the immune system, playing a role in fighting infections.

    Lymphocytes

    • Lymphocytes are smaller than monocytes and have a round nucleus.
    • Types include T cells and B cells, responsible for cell-mediated and humoral immunity.

    Monocytes

    • Monocytes are the largest of the white blood cells and have a kidney-shaped nucleus.
    • They function as phagocytic cells and antigen-presenting cells, removing microorganisms, antigens, and dead or damaged cells.
