Physical science, the systematic study of the inorganic world, as distinct from the study of the organic world, which is the province of biological science. Physical science is ordinarily thought of as consisting of four broad areas: astronomy, physics, chemistry, and the Earth sciences. Each of these is in turn divided into fields and subfields. This article discusses the historical development—with due attention to the scope, principal concerns, and methods—of the first three of these areas. The Earth sciences are discussed in a separate article. #answerwithquality #BAL
I'm not going to fully write out <span>3-4 paragraphs but I will give you some information to start out with :) I greatly enjoy doing research and writing about the things I have learned.
Arteries:
Arteries are </span>any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body. <span> Each artery is a muscular tube lined by smooth tissue and has three layers. These are the three layers and their purpose.
*The i</span>ntima-T<span>he inner layer lined by a smooth tissue called endothelium
</span>*The media- A<span> layer of muscle that lets arteries handle the high pressures from the heart
*</span>The adventitia-Connective tissue anchoring arteries to nearby tissues
Veins<span> are </span>blood vessels<span> that carry </span>blood<span> toward the </span>heart<span>. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the </span>pulmonary<span> and </span>umbilical veins<span>, both of which carry oxygenated blood to the heart. In contrast to veins, </span>arteries<span> carry blood away from the heart.
</span>Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small.
<span>
*Superficial veins are those closer to the surface of the body, and have no corresponding arteries.
</span><span>*Deep veins are deeper in the body and have corresponding arteries.
</span><span>*Perforator veins drain from the superficial to the deep veins. These are usually referred to in the lower limbs and feet.
</span><span>*Communicating veins are veins that directly connect superficial veins to deep veins.
*P</span>ulmonary veins<span> are a set of veins that deliver oxygenated blood from the </span>lungs<span> to the heart.
*</span><span>Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart.
I hoped this helped and gave you some useful information. Good luck, I hope you do well on your assignment :) ~Sadie

Respiratory therapists are specialists and educators in cardiology<span> and </span>pulmonology<span>. Respiratory therapists are clinicians trained in advanced </span>airway management<span>; establishing and maintaining the airway during management of trauma, intensive care, and may administer </span>anaesthesia<span> for surgery or conscious sedation.</span>
The DAP has three core components: knowledge about development and learning; knowledge about individual children; and, knowledge about the social and cultural contexts where children grow and learn.
Answer:
Social components influencing addiction include, though not exhaustively, neighbourhood crime, availability of the substance, tolerance and acceptance of drug use and poor support from community and society in battling the problem [6].
What are the physiological effects of drugs?
They speed up messaging to and from the brain, making you feel more alert and confident. This can cause increased heart rate, blood pressure and body temperature, reduced appetite, agitation and sleeplessness. In large amounts stimulants may cause anxiety, panic, seizures, stomach cramps and paranoia
