Increases the amount of space inside the sub 4 hemoglobin so there's loads of room for hemoglobin to occupy a red blood cell, aiding in transport as a function.
Temperature regulation in blood involves changes when we are hot and cold, such as blood vessels widening when we are hot to allow heat to radiate from the surface of the skin, and narrowing when we are cold to conserve heat.
White blood cells, also known as leukocytes, produce antibodies and help prevent infection, engulf microorganisms, and destroy viruses and cancer cells.
The bundle of His splits into two rays, distributing the impulse through the ventricle walls, causing them to contract, a process known as ventricular systole.
The heart generates its own electrical impulse and fires it through the atrial walls causing them to contract, passing the impulse on to the atrial ventricular node, which collects the impulse from the SA node and delays it for approximately 0.1 seconds to allow the atria to finish contracting.
Ventricular systole is when blood empties from the ventricles to the lungs to get oxygenated and to the body, where it is oxygenated to the body so that the muscles can get oxygen.
The cardiac cycle refers to the heart contracting and relaxing, with two key terms associated with it: atrial diastole, when the atria are relaxed and filling with blood, and ventricular diastole, when the ventricles are passively filled with blood due to the pressure of the blood filling the atrium.
Coronary bypass involves using a piece of artery taken from somewhere else in the body to bypass the blocked area of the coronary artery, allowing blood flow beyond the blockage.
