What else can I help you with?
Decreased blood flow to cardiac muscle that only injures the tissue creates a condition known as what?
Myocardial infarction is the decreased blood flow to cardiac muscle that only injures the tissue.
What type of muscle tissue causes vasoconstriction?
Smooth muscle tissue causes vasoconstriction. This type of muscle tissue is found in the walls of blood vessels and is responsible for regulating blood flow by constricting and dilating the vessels.
What does the muscle tissue look like under the skin?
Muscle tissue under the skin appears as firm, often striated (striped) tissue with a reddish or pink hue due to blood flow. The thickness and definition of the muscle can vary depending on individual muscle development and body composition.
What are the causes and effect of heart attack?
Obstuction of blood flow to the heart resulting in damage/death of heart muscle tissue.
What is the term for lack of blood supply to a tissue or organ?
The term most often used is infarction for a complete lack of blood flow to a particular organ (most often used when referring to a muscle such as the heart or skeletal muscle), or ischaemia for severely reduced blood flow. If you are simply referring to a reduced amount of oxygen then tissue hypoxia may apply.
What kind of muscle tissue would you find in the blood vessels?
Arteries have smooth muscle in their walls. The smaller the artery is, the less muscle is found. Veins have none, they count on the skeltal muscles to move blood back to the heart. The veins also have valves which prevent back flow.
What muscle tissue is found in the viscera?
The muscle tissue found in the viscera is smooth muscle. Smooth muscle is involuntary and non-striated, allowing it to contract and relax automatically to facilitate functions such as digestion and blood flow within internal organs. This type of muscle is essential for the movement of substances through the digestive tract, blood vessels, and other hollow organs.
What are the 2 main types of cell tissues in the vascular system?
The two main types of cell tissues in the vascular system are endothelial tissue and smooth muscle tissue. Endothelial tissue lines the interior of blood vessels, providing a barrier and playing a crucial role in regulating blood flow and vascular permeability. Smooth muscle tissue surrounds the endothelial layer, allowing for the contraction and relaxation of blood vessels, which helps regulate blood pressure and flow. Together, these tissues work to maintain vascular health and function.
Which type of muscle tissue is involuntry nonstraited with tapered cells?
The type of muscle tissue that is involuntary, non-striated, and has tapered cells is smooth muscle. Smooth muscle is found in various organs, such as the intestines, blood vessels, and the bladder, where it helps facilitate involuntary movements like digestion and regulation of blood flow. Unlike skeletal muscle, smooth muscle does not have the striations caused by organized sarcomeres.
What kind of tissue is skeletal cardiac or smooth?
Muscle tissue. Cardiac: the muscles in or related to the heart Skeletal: muscles that you can voluntarily control, such as your biceps Smooth: muscles in or around your organs, which cannot be voluntarily controlled (ie. the muscles in your stomach or intestines)
If blood flow to the calf muscle is 30 mL per min and the blood vessel supplying blood to the calf muscle dilates tripling its radius what is the blood flow to the muscle?
270 ml/min!
What are three of tissue that make up the heart?
The heart is primarily composed of three types of tissue: cardiac muscle tissue, connective tissue, and epithelial tissue. Cardiac muscle tissue enables the heart to contract and pump blood effectively. Connective tissue provides structural support and helps maintain the heart's shape, while epithelial tissue lines the heart chambers and forms the endocardium, playing a role in regulating blood flow and preventing clot formation.
