Vascular smooth muscle

Actions of drugs on cardiovascular preparations Introducion The experiment outlined in this report was carried out with the intention to observe and explore the effects of certain named drugs on a vascular preparation, in the cardiac region specifically. The cardiovascular preparation used in this experiment was an isolation of the descending aorta of a rat. This isolate is particularly useful as it mirrors the responses that would be observed in a human sample, thus this experiment will give

Project Background (500 words) The placenta is a fetal organ that is vital for the growth of the fetus during pregnancy. Abnormalities in placental development can result in pregnancy complications such as intrauterine growth restriction (IUGR) and pre-eclampsia (PE), which affect one in ten pregnancies in New Zealand. IUGR occurs in 3-5% of all pregnancies, and is associated with an assortment of increased risks of its own, such as hypoglycaemia, hypothermia, developmental delays and increased

medication once daily to help decrease his blood pressure. The mechanism of action of amlodipine is to inhibit calcium ion influx across cell membrane during cardiac depolarization; produces relaxation of coronary vascular smooth muscle and peripheral vascular smooth muscle; dilates coronary vascular arteries; increases myocardial oxygen delivery in patients with vasospastic angina (Vallerand et al.,

The process of vascular remodelling appears to be a consequence of direct injury or chronic disease, involving alveolar hypoxia. As a result, medial thickening, intimal fibrosis and formation of angioproliferative (plexiform) lesions (which consists of endothelial cells

system’s main functions are heat production, enabling movement, and posture. There are three types of muscles: smooth, cardiac,

Shearing forces acting on the vascular endothelium generated by blood flow causes a release of calcium and subsequent cNOS (cyclic nitric oxide synthase) activation. Therefore, increases in blood flow stimulate NO formation (flow-dependent NO formation). Nitric oxide then causes independent

Connection of epithelial tissues to muscle fiber * Supply of hormones all over the body * Nutritional support to epithelium * Site of defense reactions Locations of a Connective Tissue: Connective tissue is found everywhere in the body except the central nervous system. 3. Muscular: a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. It

7. (4 pts) Explain your allergic (inflammation) response to the bee sting. How will this response affect your BP? After being stung by the bee, one indicator that you are having an allergic reaction in this case is extreme redness of the skin. The bee sting injected allergens into your body and your body overreacts trying to fight off the allergens and cause an allergic reaction.There are minor allergic reactions and more severe ones. In this case if my body is turning red everywhere, and not

are both increased. These changes in blood volume and cardiac output are most likely due to the increased metabolic demand that result from increases in both lean and fat mass. The large fat depots in significant obesity produce a low-resistance vascular circuit that may further increase cardiac output. There may also be changes in renal absorption of salt and water. The combination of these factors is proposed to produce a form of volume overload which can give rise to high output failure later

MEDSCI 305 2013 Lab 2 – Role of Calcium in Smooth Muscle Contraction 1.0 Aim The aim of this lab was to identify the significance of calcium’s role on the contraction of the smooth muscle (1 pg. 25). 2.0 Introduction The smooth muscle (SM) which is found within the wall of blood vessels located in the veins, arteries, arterioles and capillaries. It can also be found in the stomach, intestines and urinary bladder. It has an important function of modulating the contractility
