what is the definition for thrombus?
A thrombus is a blood clot that forms in the circulatory system and remains where it forms rather than circulating in the blood.
What would lead to vasoconstriction of an arteriole?
Vasoconstriction of an arteriole can be caused by signals from the sympathetic nervous system, circulating hormones like epinephrine and norepinephrine, or local factors such as low oxygen levels or increased levels of certain molecules like endothelin. It results in the narrowing of the arteriole, which increases peripheral resistance and raises blood pressure.
What is a pulmonary arteriole?
A pulmonary arteriole is a small blood vessel that carries oxygen-poor blood from the right side of the heart to the lungs for oxygenation. These arterioles are part of the pulmonary circulation system that helps exchange carbon dioxide for oxygen in the blood.
What structures secretes renin when blood pressure in the afferent arteriole drops?
The juxtaglomerular cells located in the walls of the afferent arteriole secrete renin when they sense a drop in blood pressure. Renin is released into the bloodstream in response to decreased blood flow to the kidneys, ultimately leading to the activation of the renin-angiotensin-aldosterone system to help regulate blood pressure and fluid balance.
What makes up the renal portal system?
It is made up of the afferent arteriole which supplies blood to the kidneys. The glomerulus, which is the first capillary bed produces filtrate. The efferent arteriole takes blood from the kidneys. The peritubular capillary system, which is the second capillary bed reclaims most of the filtrate. Filtrate is what eventually becomes urine.
If a clot was to become dislodged what would it be?
If a blood clot becomes dislodged, it can travel through the bloodstream to other parts of the body, leading to potential blockages in blood vessels and causing serious complications such as a pulmonary embolism if it reaches the lungs or a stroke if it reaches the brain. It is important to seek immediate medical attention if you suspect a blood clot has become dislodged.
Thrombus traveling through vascular system is called?
When a thrombus travels through the vascular system it is called an embolus.
what is the definition for thrombus?
A thrombus is a blood clot that forms in the circulatory system and remains where it forms rather than circulating in the blood.
What are the five components of the circulatory system?
Veins, Heart, Arteries, Capillaries, and Arteriole

Why is an arteriole described as an organ?
An arteriole is not typically described as an organ. It is a small blood vessel that branches from an artery and leads to capillaries. Organs are made up of various types of tissues organized to perform specific functions, while arterioles are components of the circulatory system.
What is the function of a pulmonary arteriole?
a pulmonary artieriole is part of the respiratory system. inside the respiratory system is an organ called alveoli and the alveoli are covered in a network of capillary. the job of the pulmonary arteriole is to carry deoxygenated blood into the capillary network.
What blood clot forms after a fracture?
A clot that has dislodged into the vascular system is called an embolism. When you fracture a long bone you run the risk of fat from the bone marrow becoming dislodged into your blood vessels and forming a fat embolism.
