Carry blood from the arterioles to the venules
Which vessels transport blood between the lungs and the heart?
Pulmonary arteries and veins
What is the definition of pulse?
The alternate expansion and recoil of the blood vessel wall
What is the major cause of hypovolemic shock?
Hemorrhage or loss of interstitial fluid
What is the classification of hypertension (HTN) when blood pressure exceeds 140/90 mm Hg?
Primary essential (idiopathic)
What causes neurogenic shock?
Nerve condition that relaxes blood vessels
What is the effect of septic shock on blood vessels?
Toxins dilate blood vessels
What influences pressure in large peripheral veins?
Central venous pressure
What is the major risk factor for hypertension (HTN)?
Genetics
What is the definition of blood viscosity?
Thickness of blood
What are the components of arteries?
Tunica intima, tunica media, and tunica externa
What is the function of veins?
Collect blood for return to the heart, with valves preventing retrograde movement
What do capillaries serve as?
Exchange vessels for nutrients, wastes, and fluids
What are common disorders of arteries?
Arteriosclerosis and atherosclerosis
What can be used to manage arterial disorders?
Balloon angioplasty and vasodilators
What are potential disorders of arteries?
Aneurysm, thrombosis, and stroke
What are common disorders of veins?
Varicose veins, hemorrhoids, and thrombophlebitis
What does systemic circulation do?
Carries blood throughout the body
What is the function of hepatic portal circulation?
Assists in homeostasis of blood glucose levels
What does fetal circulation involve?
Unique structures like the placenta, umbilical arteries and vein, ductus venosus, ductus arteriosus, and foramen ovale
What factors influence blood pressure?
Blood volume, heart contractions, and heart rate
Study Notes
Anatomy and Function of Blood Vessels
- Arteries consist of tunica intima, tunica media, and tunica externa; they distribute nutrients and gases, regulate blood pressure, and serve as reservoirs
- Veins have tunica intima, tunica media, and tunica externa; they collect blood for return to the heart, with valves preventing retrograde movement
- Capillaries serve as exchange vessels for nutrients, wastes, and fluids
- Arteriosclerosis and atherosclerosis are common disorders of arteries, leading to reduced blood flow and potential ischemia
- Balloon angioplasty and vasodilators can be used to manage arterial disorders
- Aneurysm, thrombosis, and stroke are potential disorders of arteries
- Varicose veins, hemorrhoids, and thrombophlebitis are common disorders of veins
- Systemic circulation carries blood throughout the body, while pulmonary circulation carries blood to and from the lungs
- Hepatic portal circulation is a unique blood route through the liver, assisting in homeostasis of blood glucose levels
- Fetal circulation involves unique structures like the placenta, umbilical arteries and vein, ductus venosus, ductus arteriosus, and foramen ovale
- Changes to fetal circulation occur at birth, involving the closure of specialized fetal blood vessels
- Blood pressure is the force of blood in the blood vessels, with factors like blood volume, heart contractions, and heart rate influencing it
