What is NOT a component of blood?
What is NOT a component of blood?
Adipocytes are fat cells and not a component of blood. Blood is composed of plasma (fluid) and cellular elements (red blood cells, white blood cells, platelets).
Does peripheral resistance solely cause pressure dissipation and flow velocity reduction in capillaries?
Does peripheral resistance solely cause pressure dissipation and flow velocity reduction in capillaries?
Peripheral resistance is a major factor in blood pressure dissipation, but not the only one. Other factors include the diameter of blood vessels, viscosity of blood, and length of the vessel.
What is the function of the Hagen-Poiseuille equation?
What is the function of the Hagen-Poiseuille equation?
The Hagen-Poiseuille equation predicts the flow rate of a fluid in a conduit based on factors like pressure, viscosity, length, and radius of the conduit.

Study Notes
- Mammals have a closed circulatory system called the cardiovascular system.
- Blood travels from the heart through blood vessels of varying diameters.
- The systolic pressure is generated when the heart contracts and the diastolic pressure is generated by the elastic recoil of the arteries.
- Peripheral resistance explains why pressure dissipates and flow velocity is reduced in blood capillaries.
- The no-slip condition, or peripheral resistance, reduces blood flow and pressure.
- The Hagen-Poiseuille equation predicts the flow rate of a fluid in conduits.
- Precapillary sphincters and smooth muscle cells in arterioles control blood flow and flow rates.
- Interstitial fluid is recaptured through osmotic pressure and the lymphatic system.
- Blood is driven back to the heart through the action of two types of muscle tissues.
- The mammalian heart has four chambers and is composed of cardiocytes.
- The cardiac cycle is split into three stages.
- The pulmonary arteries are histologically different from other arteries, contributing to lower pressure in the pulmonary circuit.1. The heart has different stages during the cardiac cycle.
- During atrial systole and ventricular diastole, the atria contract to force blood into the ventricles.
- During ventricular systole and atrial diastole, the ventricles contract to prevent blood from entering the atria.
- Cardiac output measures the volume of blood pumped per minute by each ventricle.
- Blood is a type of connective tissue that functions in the transport of substances, defence, and fluid balance.
- Blood is composed of plasma and cellular elements.
- Plasma carries nutrients, respiratory gases, hormones, and waste products.
- Plasma also contains important proteins functioning in pH and fluid balance, clotting, and defence.
- Cellular elements of blood include leukocytes, platelets, and erythrocytes.
- Erythrocytes carry respiratory gases to and from body cells.
